Hyd malfunctioninng -control valve/Release & releif valve

Magnetic stainer to be put at Suction line

Sample procured, new design under development R&D 10.12.14 Proto will be ready by 17.11.14

Release& release valve qualityTo study setup and implement the same, either on vendor end or QA

QA 17.11.14 IT was concluded that testing facility at vendor end and at QA shall be same

CRE 1200 kg to be implemented UNDER IMPLEMENTATION Matl/QA 2W Feb'14 NG Models are being made with CRE only

2CA guide seal leak-post modified

Design needs improvement in SC tractors

ECN Implementation Matl/QA 10-12/11.14 Only Modified CA Guide to be assemble with immediate effect

3Diff hsg breather leak / ineffective breathing action

Integrated breather to be used - existing breather is in effective

New breather under trails, prelimnary trial is OK R&D 2w Dec'14 3dec 10 pcs

Pre loading process to be standarized

To ensure the pre loading process as per SOP QAcontineous

processCutt off no - QAD-5518648

Wheel thrown away after brg breakage- spacer size to be increased

Dim 53 changed to dim 40 mm to protect wheel comes out - to be revisited - to be implemented

Matl/QA 20.11.14implemented after consumption of stock 125 tractor

5RV assy - control valve mtg stud leak

Control valve mtg face Sq ness / O ring dim & material / groove depth/widh to be checked

Analysis of failure was studied, porousity problem apeared

QA/R&D New design concept drawn, trial by 2w Dec'14

6Hyd pump adopter leak from O ring

CFT to study the problem at assy line

Hyd Adopter design modified Mat/QA 18.11.14 Action taken details with cutt off nos awaited

Tendom pump with 10.9 CC to be explored Mat/R&D 4w Nov'14 Comprehensive action by Nov 14

Failed sample with proposed action sent to Xinchai on 14.8.14 - corrective action awaited

PC 3.9.14Modifed sample expected in Nov 14 from Xinchai

Spare parts stock to be purchased from Allena only Spareparts 3.9.14 Drawing already approved

Radiator to be protected by providing net gril till improvement from Xinchai in water pump get implemented

Proposal along with proto photo re sent to RD by PC- trial to be done

RD 6.9.14

Coolant bottle mtg location to be changed

New location drg & proto ready by month end- trial by RD 5.11.14

5 saples received, but not approved yet, pending with R&D

NRB failure understodd due to procurement from unauthorised source

To ensure procurement of NRB 2016 from quality source Matl NAAction already taken by quality source of bearing

NRB 2016 to replaced with Sintred bush

NRB to replace with cintred bush - further study to be done

RD NA Dropped yet as action taken as above

Failed items to be analysed metallurgically - report to share & spectroscopic analysis to be done

QA 3.9.14 Ok

Radiator( high value) - conseq failure a) water pump shaft

broken b) coolant resorvoir mtg at radiator breakage

CFT observation is shaft of water pump breakage subsequent to

bearing failure - brg is of inadequate strength

9Plannet carrier (NRB 2016 fails & conseq teeth damage )

Spider kit strengthening to be explored -CFT analysed the failure

7Power steering hard < 1000 rpm with tendom pump

Tendom pump flow 8.5 cc / rev & AX series pump flow 9.0cc/rev - Drawing of M/s Bosch approved

4Hub brg - power steering - 30206 breakage

SN Field Concern Action concluded Further Actions planed Resp Trgt date Remarks

Oil starvation observed - Scoop to be added for better lubrication of Spider kit -ECN to be released

RD 17.11.14

Surface finish & cylindericity of BP shaft to be improved

ECN released - QA to submit report QA 3.9.14

11 Brake pedal Misaligned Brake pedal being received in pair paired brake pedal to be painted & fitment in set Done

12 Sealing screw ( drain plug - Gb) ERN -209 /31.7.13 released Sealing tape to be used Matl

13Battery Side shifting in AX series

K- series & NG series already have side batterry

Battery Side shifting in AX series to be done -ECN to release by 18th Aug -Implementation

Done Implemented

14Power steering tank leakfrom breather

In effective breathing OK , if oil level is upto bottom marks - either marks to be changed or bottle to be changed

QA 10.12.14 Intermediate action with low oil level

15Trumpet hsg - break from Flange

Low flange thickness & weaker strengthening ribbs wrt to compititors

Wall thickness increased from 20mm to 23+1 mm - sample received

Mal/QA 21.11.14 Price increase by 2kg per piece

16 Oil pressure switch Not working - post modified failure

Data for post modifed failure given - to be analysed QA

1Trcebility of major items wrt chassis no

To elliminate possibility of items mix up or claims agaisnt differrnt chassis no

List of major 20 items provided - traceability to be work out

R&D /QA

2Sticker on tractors how to operate tractor on different implement

to facilitate the customer to use appropiate gear & engine rpm - our eng rpm range is from 1800- 2300 rpm

mktg given the sample to R&D - to be work upon R&D /QA 1W Dec'14

NSD / 31.10.14
