Does anyone know if Don M installs new copper sealing washers when he does new nozzles? To me, they look like the old ones that were on the injectors when I sent them in. I have the new washers if necessary, but how do you get the old ones off? They are on there TIGHT.

Thanks for the help.

 

remove them with a pliers carefully not to damage the nozzle if they are old i dont think don would put used ones on? maybe he forgot to take them off? id call him!

 

Thanks...that's exactly what I was thinking...it doesn't make sense to rebuild them and put on new nozzles and old copper washers. They just don't look like the new ones I bought from Cummins

 

I am not one to doubt Don's work... maybe they were used, but within spec.

However, I would call him before messing with anything... we are only human, mistakes are made.

 

It was ten years ago but my Don M's came with new washers...

 

Don sends new washers with injectors.
Take a close look at washer, do you
see a mark where they were compressed.
If you don't see a mark they are new.

 

I have a call in to Source Auto, who will contact Don for me. The new ones I have are all nice and square on the edge, and about 1.5 mm as spec. The ones on my injectors are rounded, compressed and appear to be uneven, so I think is is just an oversite, as MadHat suggested can happen with humans...

I'll update when they get back to me...

 

Just got a reply from Bill at Source... Don says that they ARE new, however they are slightly rounder and thinner than the Cummins stock ones. So, we're all good. At least I have a spare set of washers if I need to pull the injectors again
