Engine/Transmission (1994 - 1998) overflow valve washers

[Blackcloud]

Simple question. When doing timing,is it safe to reuse the overflow washer,or should a new one be used?

If you mean the sealing washers on the banjo bolts they can be reused.

Every now and then the washers on banjo bolts will leak if reused. But not always, most of the time they are O. K.

Why are you messing with the overflow valve washers while setting timing?

 

[illflem]

If you meant the delivery valve washer, it should be replaced

 

[Cooker]

Not all pumps have delivery valve washers. What year is your truck?



If your truck does have them, like illflem said, they do need to be replaced.

Sorry,I ment delivery valve washer(brain fart),too many irons in the fire.

If I am not mistaken, your 96 probably will not have D-Valve washers. Mine didn't.

I'm not sure if my 97 has them or not but Drees1 did my timing and we didn't replace anything and I have no problems.

I thought it was delivery vavle o-ring that needed replacing after doing the timing. Are on 2 different subjects?



O-rings Bosch 2 410 210 033-000

 

[Cooker]

The following is from Piers' delivery valve installation instructions:



"7. Some older 160hp pumps have copper or steel gaskets under the delivery valve holder. These should be replaced at this time with the new ones from the kit NOTE: If your pump did not have these gaskets do not use new ones. "



John,

The O-ring is a different animal, but you bring up a good point that it should also be replaced IMO. Some say they can be reused if removed carefully. I guess I am not careful enough and mine always get destroyed

I checked with the local,very respectable Bosch repair shop today. They looked up my truck in their application guide and said that delivery valves in the 96 trucks don't use washers. Now I can time in peace... Thanks for all your responces.
