Engine/Transmission (1994 - 1998) Timing... Replace seals & washers each time?

[Mackie007]

I just got my Snapon timing kit in so I'm tempted to set the timing this weekend. Problem is I didn't buy any of the consumables listed in the timing faq yet. Do you guys that play with your timing alot think this would be:



Probably ok?



Or best wait till I have the parts on hand?



Best Regards,

Mac

Have parts on hand or it will not seal. Always replace the oring for the delivery valve.

 

[Mackie007]

Thanks for the quick responce, I'll exercise some patience and get the seals before I proceed.



Best Regards,

Mac

I would replce the lock washer and the O-Ring. I have gotten away without replacing either but for the $8-$10 it cost to replace them it worth doing so IMHO.

 

[Cummins4Life]

Anybody have part numbers for the Oring and washer?

 

[Mackie007]

I copied these from the FAQ listed at the top the 12 Valve Engine and Transmission forum.

Mackie:



Your 1996 pump likely does not have delivery valve sealing washers. I bet yours is a "gasketless" design. Most 1994-1995 used these washers. Cummins literature shows pump #'s that should not have the washers under the delivery valves.



If your nervous wait, but you are likely ok. I do like to change out the lock washer on the injection pump gear/shaft each time. Its cheap insurance.



Clean the taper and gear really well (Electrical Contact Clr. or Fast drying brake cleaner).



Good luck
