Hello! I am having trouble finding a gasket kit for my '76 OM616's injection pump. Could someone provide a good source please? I have some oil leakage from the bottom I want to fix but if I am going to pull it I would d like to go through all gaskets while I have it off.

I will be doing a 2nd tank WVO system on this so Viton O-rings would be a plus.

Most kits I see are for '77 and up and start at 068 and go up, I have an 066

PES4M 550320 RS58
0400 114 066

thanks!

What is leaking from the bottom?

The kits used to show up on ebay. How to identify which on you need is going to be a chore.

Certified Bosch fuel injection shops should be able to get them. If not the original bosch other companies make the kits.

People used to purchase the Viton O-rings separately.

Note some kits are for only the fuel injecting Pump and other kits included the fuel injection pump and the governor.

It does not seem to hold the correct amount oil when I attempt to fill the pump, so I suspect the lower gasket. That and I get an oscillating idle on cold start up, maybe pneumatic govenor o-rings?

Either way when the time comes to pull this off I would like to have all the parts to be able to address anything it needs. I have seen the Ebay ones but non are definitive to work on my pump.

I have some local German auto repair shops that I will call and see if they have a source.

thank you for the reply

still looking if anyone has a supplier

Did you reach out to a local Bosch injection shop?

I did, they couldn't help me. It is a very small town and I think they stopped working on the older vehicles a while ago. I guess I can try some town North or South of me. I just didn't think it would be this hard to track down.

If you pull out the diaphragm you need to be sure to note where the shims go and i what order.

A new diaphragm is a separate part from the kit. The O-rings in the vacuum area go on the shaft. People have been finding the shaft and or bushing are worn and leaking vacuum.

Buried somewhere in the repair links there is testing the hosing for vacuum leaks, and you may even find the gasket kit number.
