This Part of the Manual contains the recommended removal, overhaul and installa­tion procedures that should be taken when servicing the steering system on the MF 150, 165 and 175 Tractors.

Determine the possible cause of any malfunction by consulting the "Trouble-Shoot­ing" Section of this Manual before any attempt is made to repair the system. Follow­ing this practice will result in more accurate maintenance of the steering system and will aid in preventing unnecessary repairs.

CHECKING AND ADJUSTING CARBURETOR AND THROTTLE LINKAGE FOR MF 135 AND MF 150 TRACTORS

To adjust, refer to the following chart and proceed as outlined.

Engine Speeds: Low Idle Speed .................................................................. 725-775 rpm Maximum Engine Speed (No-Load) ............................................ 2225-2275 rpm

Ignition Timing (Crankcase Degrees and RPM): Static Setting .................................................................. 120 B.T.D.C. Desired Dynamic Setting ...................................... Adjust to provide 260 B.T.D.C.

1. Choke Adjustment - Disconnect air intake hose. Operate choke knob and observe position of choke plate in carburetor to make sure it will fully open and close.

Adjust choke cable so plate will be FULLY open when choke knob is located 1116 inch away from panel. Reconnect air intake hose and tighten clamp securely.

2. Carburetor Control Rod - With the engine stopped, disconnect carburetor control rod clevis from governor control lever. See Figs. 1 and 2. THE ENGINE MUST NOT BE OPERATED WITH THIS CONTROL ROD DISCON­NECTED.

Move the governor control lever fully rearward (if linkage is connected, by moving the hand throttle to the maximum throttle position). Then move carburetor control rod rearward to the max­imum throttle position and observe location of pin holes in governor lever and clevis.

If control rod is properly adjusted, it will be necessary to move the clevis forward slightly (ap­proximately 1132 inch toward the closed position) to align the pin holes. Readjust clevis length if required, retighten locknut and reconnect clevis to governor control lever. MAKE SURE PIN FITS FREELY AND THAT CLEVIS DOES NOT BIND AGAINST LEVER.

3. Carburetor and Distributor Adjustment, See Figs. 1 and 2.

a. Start engine and allow it to reach normal operating temperature. TEMPORARIL Y lower engine idle speed to approximately 500 rpm by adjusting the idle speed stop screw. This will aid in adjusting carburetor idle mix­ture and prevent the distributor advance mech­anism from operating.

b. Install timing light and check that dis­tributor is timed to the proper static setting (before distributor advance mechanism starts operation). Readjust timing as required.

c. Check and adjust the idle mixture. To adjust, turn idle mixture adjusting needle "in"

@ 2000 rpm or higher

until engine rpm begins to decrease. Then turn needle "out" until engine operates smoothly at the highest rpm.

d. Readjust low idle speed to final setting of725-775 rpm.

4. Hand Throttle Linkage - If throttle link­age is being replaced or improper governor opera­tion has been encountered, proceed as outlined.

This part of this manual is concerned with the overhaul procedures for the Perkins AD3. 152 Diesel Engine. All of the procedures and service information contained in this part assume that the engine has been removed from the tractor and pertain only to the basic engine itself, without regard to any particular application in which the en­gine may be used.

NOTE: For specific detailed information concerning the lubrication systellt and the other engine systems of the AD3.1S2 engine, refer to the appropriate part within this section of your Ilutilual.

Before starting disassembly, make a complete diagnosis of the engine to be sure that an overhaul is really necessary. If the overhaul is necessary, inspect the en­tire engine for any evidence of external leaks, or defective parts, that must also be corrected before it is assembled and returned to the customer.

Thoroughly steam clean the engine before disassembling it or removing any com­ponent parts of the fuel system. Also, make sure to cap or otherwise cover all fuel openings as soon as they are exposed to prevent dirt from entering the fuel system. CLEANLINESS IS VERY IMPORTANT AND CANNOT BE OVER-EMPHASIZED.

Where the right and left-hand sides are mentioned in this Part, it refers to the en­gine as viewed from the rear. Direction of engine rotation, however, is viewed from the front.

DESCRIPTION AND OPERATION

The clutch assembly includes a cover with a splined hub, a spring-loaded pressure plate and a friction disc. See Fig. 1.

The splined hub in the clutch cover is con­nected to the PTO input shaft and the cover is bolted to the engine flywheel. Therefore, the clutch cover and the PTO input shaft will turn whenever the engine is running.

Nine coil pressure springs are used to obtain a pressure plate loading of 945 to 1035 lbs. The pressure plate is controlled by three re­lease levers.

The friction disc is connected to the main transmission input shaft and is released by the clutch release levers and pressure plate. This controls the tractor drive train and permits the tractor ground travel to be stopped or started while the PTO shaft continues to rotate.

This Section contains the recommended overhaul procedures for the standard 6-speed transmission (dual clutch), removed from the tractor and placed on a stand. Although some components will vary slightly, (depending upon the unit in which the transmission is installed i. e. gasoline or diesel engine) the basic overhaul procedures will remain the same. Refer to the Tractor Parts Book to ensure that the correct parts are ordered.

For instructions pertaining to removal and re-installation from the tractor using this transmission, refer to the appropriate tractor "write-up".

DESCRIPTION AND OPERATION

The Hydraulic System described in this part is similar to the one used on the MF 35, 50 and 65 Tractors. It has Draft Control through the top link and Master Control Spring, also Posi­tion Control regulated by the operator.

One difference in the two systems is that the MF 35, 50 and 65 Tractors have a slow re­sponse control which restricts the dropping of the implement by regulating the amount of travel of the control valve to an exhaust posi­tion. On this system, the rate of lowering an implement is controlled by a dash pot, which retards the control valve toward the exhaust position. This enables the tractor to be oper­ated in slow response over an uneven terrain and still maintain an even depth of the imple­ment. The control valve is spring-loaded to­ward the intake side, rather than toward the ex­haust, as is the earlier system. The hydraulic 'system can be raised into transport position or lowered pOSition with either the draft control

-lever or ·the position control lever. Fig. 1 shows a view of the lift cover assembly, stand­pipe and the hydraulic pump assembly posi­tioned as they would appear in the tractor also shows identification of Controls.

To operate the hydraulic system in poSition control, the draft control lever must be all the way to the rear of the quadrant. The lower links can then be positioned by the position con­trollever. When the position control lever is moved toward the rear of the quadrant, the lower links will raise. When moved toward the forward side of the quadrant, the lower links with lower in proportion to the poSition of the lever. This lever is used for attaching imple­ments and for operating implements that are not draft controlled.

To operate the system in draft control, the position control lever must be placed in trans­port position (to the rear of the quadrant against stop). The draft control lever, which is on the outer quadrant, is provided with an adjustable locater which allows the operator to lower the implement to the same depth each time. When operating in draft control, the im­plement is raised to transport and lowered with the draft· control lever.
