A.-Start with aligning the installation to the driven machinery in all 3 directions by means of the engine jacking bolts or by means of jacks to support the suspended machinery. Align the installation approximately 5 to 10 mm higher in vertical direction relative to the driven machinery. A more accurate vertical pre-alignment can be calculated as follows:Measure the TB value of the supplied mounts at TB1 or TB2 position , see fig.1.Take the calculated static deflection of the mount from the relevant calculation report and multiply this with 1.15.Subtract this value form the unloaded TB value of the relevant mounting type from the table at section 2 . The result of this calulation subtractred with the supplied TB value will give the vertical pre-alignment value of the engine above the input shaft of the driven machinery, for an alignment with zero pre-set in the vertical direction. Formulated as :Vertical pre-alignment (mm) =(TB supplied)-((TB unloaded)– (static deflection x1.15)) In both other directions the alignment can be made to the definite values. B.-Fit an intermediate plate with jacking bolt holes under the basecasting (B), dimensions depending on the method of chocking. Insert bolts through the 4 holes in the base casting in the intermediate plate use bolt size, material and tightening torques as per below table:

C.- Remove nut (H) and washer (G) and place adjusting nut (F) in position by turning it, until the top of the nut is above the top casting (A) according to below table, see also fig.1 .

Fig. 1 :setting of HA nut pos.F. C.-Attach each mount to the engine/installation fixingholes and fit washer (G) and nut (H) to the internal limiter assembly (C.1+C.2) handtight at this stage.Take care to bring the internal limiter assembly (C.1+C.2) in the upper position by turning it anticlockwise with a spanner on the top hexagon.The internal limiter assembly is supplied asembled.Make sure that the identification plate can be read in the installed position. E.-With the engine correctly aligned ,fit 4 jacking bolts each mount in the threaded holes of the intermediate plate. Lock the bolts with equal moderate torque to the foundation.The mounts are supplied pre-loaded by means of 4 bolts , nuts and washers (J+K+L), these have to be removed by first unscrewing the nuts until they are free from the top- and basecasting (A and B) and unscrewing the bolts from the threaded holes in the basecasting (B).Remove the bolts and nuts sideways from the slotted holes in the top casting (A). F.- Gently load the mount by means of the engine jacking bolts or jacks until the engine load is completely taken by the mounts. Make sure that the installation load is as near to the operating condition as possible.

G.-Turn the internal limiter assembly (C.1+C.2) down until a greater torque is felt. At this point the central buffer foot touches the intemediate plate. Tighten the top-part to the bottom–part with the maximum torque according to the below table.

H.-Gently turn the internal limiter assembly (C.1+C.2) anti-clockwise up, taking care not to disconnect the top-part from the bottom-part .Should this connection be released then the above procedure should be repeated. To avoid the disconnection, either the installation should be locally lifted over 1 to 2 mm or the top casting(A) of the individual mounts should be lifted the same distance by inserting the 4 pre-tensioning bolts (J) in the base casting (B).The lower nuts (L) should be turned against the top casting (A) and Raise the top casting (A) Remove the pre-tension bolts (J) after the internal limiter assembly (C 1+2) is free to rotate. Repeat the same for all the mounts. I.-Check the load distribution over the individual mounts at the positions TB 1 and TB 2 . The deviation in average TB values between the mounts should not exceed 2 mm and ideally be less. The deviation from TB1 to TB 2 of a single mount has to be less then the maximum deviation in mm as per below table.

Leave the engine in this condition for a minimum of 48 hours, preferably 1 week, before continuing with the alignment of the engine. J.- Correct the alignment in vertical direction by means of turning the jacking bolts in the intermediate plate.Apply maximum 1/3 turn (equals to 2 sides of the hexagon) each jacking bolt each time , taking care to keep the TB values within tolerance. In case of the horizontal alignment needs to be corrected in either direction, the top- and bottomcasting (A and B) have to be fixed again by means of pre-tension bolts and nuts (J+K+L) same as supplied. In this condition for all the mounts , the engine can be moved on the jacking bolts , applying force only at the intermediate plate .Remove the pre-tensionbolts as described in section E. After completion of the alignment work, the holes for the foundation bolts can be drilled through the intermediate plate. See fig. 2

Fig. 2:Driling of foundation bolt holes through intermediate plate. K.-The individual chock thicknesses under each mount can now be measured for chock manufacturing , or can be prepared for cast resin chocking between the intermediate plate and the foundation. L.-The limiter clearance in each mount must now be set as follows : Turn the internal limiter assy (C.1+C.2) down (clockwise) until it makes contact with the foundation. From this position the internal limiter assy (C.1+C.2) should be turned anticlockwise upwards over 2 revolutions. Note:In case of an asymmetric limiter clearance the limiter should be turned anticlockwise upwards over the revolutions calculated as follows: required clearance / thread pitch. See the accompanying drawing for the limiter clearances the thread pitches are given in the first table of this instruction. M.-Tighten nut (H), tightening torque according to below table and at the same time block internal limiter assy (C.1+ C.2) with a spanner at the top hexagon.

NOTE: The rubber element must not be painted , if painting is carried out on the supported machinery , the rubber element must be shielded from the paint .

2. Maintenance

Maintenance of the rubber element should be done in accordance with DIN 7716 , to achieve the best possible lifetime of the rubber element. Under normal working conditions and professional lay-out of the mounting system a lifetime expectancy of 8 to 12 years of the rubber element is realistic. The actual lifetime is influenced by (dynamic) load and environment. The functional lifetime of the rubber element is determined by the vibration behaviour of the supported mass for which the ISO 10816-6 section 6A/B gives a good guidance. The maximum working deflection due to nominal load , creep and thermal loads that the mount would accept is stated in the tables below for each individual type and compound. The mentioned values are to be measured at 20°C rubber temperature.

The environmental influences on the lifetime can be minimised by periodical visual inspection of the rubber part for oil contamination and damages .Any oil contamination should be cleaned with conventional mild household cleaning agents. Cleaning of the rubber element should be done in accordance with DIN 7716 , to achieve the best possible lifetime of the rubber element. Under no circumstance the rubber element can be cleaned with solvent cleaning agents, if the direct environment of the rubber element is cleaned with these aggresive solvents , the rubber element must be cleaned afterwards with the above mentioned cleaning agent. Rubbersurface temperature of the mounts must be within +70° C / -20° C.

3. Periodical inspection.

-Introduction: The functional behaviour after a period of time in service of the T series mounts is influenced by several environmental circumstances during the service life of the mounts. Provided the installation of the mounts is done according to the appropriate installation instructions only a periodical inspection of the mounts is necessary to determine the condition of the mounts. The following criteria should be inspected and reported: -Mount identification numbers -Mount working temperatures -Internal limiter clearances. -Load situation over the mounts (TB values). -Rubber surface condition. It is recommended to incorporate only the rubber surface inspection and internal limiter clearance in the normal service schedules of the installation with a minimum of once each year .The other inspections only in case of a major overhaul.

10

-Mount Identification: All mounts of the T series are equipped with an Identification plate on the top casting and additional stamped number on the top casting (See fig.3). Note the mount type (as indicated on the ID plate) and the stamped number on the top casting into the inspection report at the end of this manual for each mount. Note that on one installation all mounts are of the same type.

Fig. 3:Stamped Identification number and ID plate on the mounts.

-Mount working temperature: During all inspections on the mounts, it is important to note the rubber surface temperature of the mounts, as the thermal expansion of the mounts influences both load condition (TB value) and limiter clearances of the mounts. Note the rubber surface temperature on the inspection report at the end of this manual when you measure the TB values! -Internal limiter clearances: In the warm condition measure the clearance between the internal limiter (see fig.4 ,C.1+C.2) and the foundation through the slot in the base casting (B). Insert a thin metal strip (Hacksaw blade) of about 1 mm thickness in the slot and slide it all the way through to the other side of the mount. Turn the strip up until contact is made with the underside of the limiter on one side and the foundation on the other side. A clearance of 1,5 mm for T35/50/60/90 and 2 mm for T75/140/200/230 at this position is the absolute minimum that can be accepted in the warm condition.

Fig 4: limiter clearance. Same applies for the clearance above the buffer to the base casting (B), see fig.5 : This upper clearance can not be checked directly, but if you will find a clearance below the buffer smaller than the height of the slot, then the upper clearance is present. This is easily detected by sliding the mentioned strip over the topside of the slot until contact to the buffer is made.

Fig. 5: limiter clearance above

12

In the case that a resistance is felt while sliding the thin strip below the underside of the limiter or if it is not possible to slide the 1 mm thick strip completely through to the other side of the mount, then there is not enough clearance between underside of the buffer and the foundation. The limiter clearance has to be set before commencing with other service activities. It is advisable to set all the limiter clearances to avoid limiter contact at another position after adjusting one limiter, due to redistribution of the load on the mounts.

Note the measured limiter clearances as ok or not ok together with the mount surface temperature on the inspection report at the end of this manual.

When appropriate, the limiter clearance in each mount can be set as follows : Loosen the connections with the suspended machinery above each mount by removing (I) and loosening nut (H) see fig.4. The limiter clearance in each mount can be set as follows: Turn the internal limiter assy (C.1+C.2) down (clockwise) , until it makes contact with the foundation. From this position the internal limiter assy (C.1+C.2) should be turned anticlockwise upwards over 2 revolutions. In the adjusted condition the position of the central buffer should be marked relative to the suspended machinery, see fig.6.

Fig. 6:Marking limiter position after adjustment.

13

Tighten the nut (H), holding the central buffer (C.1+C.2) by the top hexagon,see table at section 1 M or the relevant mount drawings for the used tightening torques of the bolt connections. -Load condition (TB values): With all limiter clearances in tolerance , the TB values can be measured of all mounts on 2 reachable points TB1 and TB2 of a mount and always in the longitudinal direction of the installation , see fig.4 and fig.7.

Fig.7: Position of TB measurements The TB values represent the distance between Top and Base casting in correspondence of the machined surface on the base casting and are measured with a sliding caliper as shown on fig.8:

Fig.8:Measuring TB values with sliding caliper.

Longitudinal direction

The measured TB values are averaged for one mount and compared to the values of the other mounts. The minimum TB value for a mount type and rubber compound are given in the table at section 2 ,maintenance. The deviation from TB1 to TB 2 of a single mount has to be less then the maximum deviation in mm as per table at section1,installation. The temperature of the rubber mount surface must be measured and noted together with the average TB value on the linspection report at the end of this manual. -Rubber surface inspection: Inspect the rubber part visually for oil contamination, ozone cracking, swelling and mechanical damages. Note the condition on the inspection report at the end of this manual. The rubber element should be replaced either when the rubber element is swollen due to contamination or cracks in the surface. In case of replacement of the rubber element, attention is made to the identification number and plate on the mount .When ordering spare parts always mention the stamped identification numbers see fig 2.

4.Disassembly and replacement. Disassembly: Before commencing any work on the mount,mark the mount and the installation with the same individual marking at the installed position.For instance 1P, meaning nr .1 mount on portside of the installation. Attach the pre-tension bolts and nuts/washers (J+K+L) fig.4 , to the mount and clamp the top casting (A) between nuts and washers (J+K+L), taking care not to change the TB value of the loaded mount. Remove cap (I) and unscrew nut (H) and remove together with washer (G).Hold limiter (C 1+ C2) by top hexagon while unscrewing nut (H). Support the installation by means of a hydraulic cylinder or similar nearest to the mount to take the weight of the to be removed mount, create a gap of approximate 2 mm between underside of installation and HA nut (F) Carefully mark the position of the basecasting (B) to the intermediate plate and remove the bolts holding the basecasting (B) to the intemediate plate The mount can be removed sideways by removing the top-part (C1) of the limiter from the bottom part (C2) by screwing anti clockwise the limiter up by means of the

15

top hexagon on the top-Part (C1) until the top part can be removed.The mount can now be removed sideways . With the mount removed fom the installation, disassembly of the mount can proceed. In the case of necessary replacement of the rubber element (D), we advice to ship the mount to VULKAN-DMR for replacement and inspection. Shipping address; see: www.vulkan-dmr.it. Should you choose to undertake the work on board , the following procedure should be followed; Note the use of a hydraulic press or special tool according to fig 9 is necessary.

Fig 9: dismantling tool Inspect the threads of top part limiter (C.1 ) on dirt and damages before attempting the asembly to C.2. Assemble top-part of limiter (C.1) in bottompart ( C.2) and turn the top-part clockwise in until top and bottom parts are connected , gently turn the assembly clockwise down , releasing the bufferdisc (C.2) from the base casting (B). Put the pre-tensioned mount on it’s side to free the underside of the base casting (B).Turn the limiter assembly down until the bufferdisc can be held by hand and

16

release the connection between top and bottompart (C.1 and C.2).Remove top and bottom part from the mount by turning both parts individual anti-clockwise. Measure the TB values at the known positions and note for later usage. Place the mount in a hydraulic press or the VULKAN-DMR dismantling tool and release the nuts (L) below the top casting (A). Press the top casting with the hydraulic tool until the upper nuts (K) are just free from the top casting (A) While fixing the position of the top casting , remove the pre-tension bolts and nuts (J+K+L). Sligthly remove the load from the top casting (A) allowing it to rise to the unloaded height. Remove the mount from the tool and tap the top casting (A) outer diameter from bottom to top with a plastic hammer, to release the rubber element (D) from the top-(A) and base (B) casting.If the rubber element (D) remains stuck in the top-casting (A), thin steelbladed tool can be inserted between Rubber element (D) and top-casting (A) where both parts meet.The rubber element can then be levered out gently , taking care not to damage it in the case it should be re-used again. Remove rubber bushing (E) from base casting (B) . Carefully inspect all parts of the mount(s), order spares by contacting VULKAN-DMR (www.vulkan-dmr.it). Make note of the punchmarked ID nr on the top casting of the mount as shown in fig 2 and the information on the ID plate. Allways refer to these numbers when ordering spares. Assembly: Inspect parts for re-use and replace if needed. Press in rubber bushing (E) by hand in base casting (B). Place rubber element (D) on base casting cone (B) . Place top casting (A) on rubber element (D) , align slotted holes to base casting threaded holes. Place pre-tension bolts and nuts (J+K+L) in the threaded holes of the base casting (B) .Nuts (K+L) above the top casting and below top casting. Ensure at least 15 mm clearance between top casting (A) and lower nut (L) Place the mount in the hydraulic press or special tool (fig.8) and press the top casting (A) until the noted former TB value is achieved. Fasten the upper nuts (J+K+L) to the top casting (A) firmly , release the press or tool.Re-check the TB value and correct if necessary by adjusting the upper nuts (J+K+L). Tighten the lower nuts (L) to the top casting (A). Place the partly assembled mount on it’s side , allowing the lower part of the limiter (C.2) to be inserted from the base casting in the HA nut (F). Screw in the limiter by hand holding the bufferdisc of the limiter (C.2), until the bufferdisc is just in contact with the base casting (B).

17

The mount is now ready for installation. See section 1 , starting at B, for installation of the mount , fit the top part of the central buffer C.1 to the lower part C.2 at the conveniant moment

5. Storage & Spare Parts

Storage of the rubber element should be done in accordance with DIN 7716 , to achieve the best possible lifetime of the rubber element. It is advised to store the rubber elements in protective enclosures, at an air temperature of maximum 25°C and avoid a high degree of humidity and exposures to Ozone and Ultraviolet light. The rubber element can be protected for a period of approx 2-3 years with a protective transparent oil resistant layer on request. It is advised to replace the mounts in case of a refitting of the suspended machinery. It is advised to store spare parts with a minimum off 1 complete mount per suspended machinery. In case of replacement of the rubber element, attention is made to the identification number and plate on the mount .When ordering spare parts always mention the stamped numbers and type designation , to allow us to supply an identical product .

6.CONCLUSION -The calculated natural frequencies ensure at cruising speed an excellent isolation towards the dominant 4th and 8th order alternating torque moments as can be taken from the Campbell diagram. There are no rigid body resonance behaviour at 440 rpm and 900 rpm under normal combustion. The first order should be well balanced; at misfiring condition higher amplitudes are expected at around 450 rpm. -The deflections due to gravity are within the allowable 12,5 mm for T90 in 55° Sh.A. -The load due to impulse loadings are within the max values acceptable by the mounts. -The flexible mounts have been selected in order to reduce the effect of a machine on its environment, according to Vibration Severity Level 7.1, ISO10816-6, Table 1. The calculated foundation forces expected at resilient mount base calculated due to 8th order excitation are of 9,9 N in lateral direction and 4,8 N in vertical direction. 7.-DISCLAIMER. The 6 DOF analysis is based on the data provided by our customer. The analysis itself was carried out using approved methods of analysis. The conclusions from the 6 DOF analysis depends therefore on the data, provided by our customer, of the individual system components (overall dimensions, masses, inertial values, connections) and from the characteristics of the VULKAN-DMR mounts selected. Missing data is replaced by assumptions based on experience or taken from available data bases , it is the customer's responsibility to check the validity of the INPUT data used in our analysis. Changes or additions to the data initially provided can lead to changes in the system's response, so that the conclusions initially drawn up are no longer valid. VULKAN-DMR takes only and full responsibility for the validity of the data concerning VULKAN products. The 6DOF rigid body analysis is based on STEADY STATE (excitation independent of time) operating conditions. TRANSIENT (excitation time dependent) operating parameters, in particular frequent shock/impact loadings, requires a transient analysis. The analysis EXCLUDES possible interaction between the considered system and other coupled systems. It is the customer responsibility to verify VULKAN-DMR 6 DOF analysis by supplying a copy of the analysis for the purposes of data validity to all sub suppliers. VULKAN-DMR must be immediately informed, in writing, of any changes to the data originally provided. The analysis is based on data supplied to VULKAN-DMR by designated persons. Liability for the validity of this data is not accepted by VULKAN-DMR.
