Fuel Injection Pump Delivery Valve Holder I
Dear (salutation):
We have become aware of a number of incidents involving the PC2.2, 2.3 and dual fuel engine, where a fatigue crack has occurred in the fuel injection 5
pump delivery valve holder. The crack is initiated at the filter seat radius l
(shown on attachment) and progresses to the holder 0.D.
The crack results from an insufficient radius at the filter seat, causing a stress riser at this point. This may result in leakage of fuel oil under high pressure during the injection stroke, creating a potentially dangerous situation.
Holders produced prior to January 27, 1982 have not been observed with this condition.
To insure reliable operation of your injection equipment, we recommend the following:
1.
Return all existing delivery valve holder shelf stock (Part No.
P12606909) to our Beloit facility for inspection. All holders found with improper radius will be replaced.
2.
Nolders installed in new or rebuilt pumps after January 27, 1982 should be removed from pumps and returned for processing per No. I above.
3.
All holders must be removed from pumps on engines built after January 27, 1982 and returned for processing per No. 1 above. A listing of your engines in this category is listed below.
To facilitate change-out, Fairbanks Morse.will make available a pool of holders for replacement purposes. Please furnish your purchase order stating scheduled shipment requirements based upon your planned change-out schedule.
Our invoice will be rendered with shipment. Upon receipt of new material from Fairbanks Morse, return suspect holders to Beloit for full. credit.
Prior to returning any holders, please attach the enclosed Returned Goods tag and mark the shipment clearly with this identification number.
Inconing 1
- 12/3/84 shipments should be made prepaid.
Return shipments will be prepaid by Fairbanks Horse Industries. Labor for removal and reinstallation on the engine will be to the users account.
Instructions will be provided with each shipment. This offer will be valid for shipments received through June 30, 1985.
If you are in doubt regarding the age of a holder please return for credit.
To summarize:
1.
Estimate your requirements (include shelf stock).
2.
Furnish purchase order with schedule and " ship to" instructions.
3.
Arrange for replacement as soon as material is available.
4.
Return holders for credit.
We regret the inconvenience caused by the actions recommended above; however, we appreciate your assistance in correcting this matter.
Very truly yours, T. J. Skinner Manager, Product Support TJS/bkw Engines Built After January 27, 1982 - (listing of engines)
