I have a NA 1.6 in a rabbit with a leaking pump seal. It is the one on the front. Can someone give me a part number and a place I might be able to order one?

I don't know the number but a guy on ebay is selling the entire VE pump seal kit. I ordered one and really didn't need anything but the top gasket, so I might have the seal you need left. Let me know if you want it. Others on here may tell you and I would mostly agree that when one seal goes the rest are soon to follow. You might want to send it to someone to reseal it....If your cheap like me you won't and will just try to get by until you can afford to do it all.

I think being cheap is a precursor to owning a Vw diesel. Only on second thought, it's not really being cheap...more like "frugal". I really only need the front seal but I see what you mean about the others leaking. I have never had a top seal go but I have thrown several pumps away for leakage issues. I never knew they could be resealed. I might fashion a holding jig out of an old pump engine mount. I broke my vise so I won't attempt a full reseal until I can get another one and ensure the pump is held vertically.

Thats actually a great idea.

Well, I removed the pump and the seal and found some shaft play in the main shaft. i am guessing this is what caused the seal to go. I can move the shaft emought to see fuel squeeze out so I am guessing that is bad. Even worse it looks as if that bushing/bearing is the 1st thing to go into the pump during assembly. Any tips??

Well there i sonly one bushing in there, once you get the pump taken apart replacing that bushing isn't to bad.
Good idea to get a book.

I though I had a PDF on them but looks like I just printed it.

It's out there somewhere on the interweb.. If I come across it I will post up the link.

Guess I had better do some looking. I suspect you are corect though. How could a single bushing last with those forces against it..

I have an old 1.5 pump that was sitting for 20 years. It was completely siezed. I took the pressure head off this weekend to practice . As long as the parts were all frozen together it was a snap to reassemble. After I loosened them up I had some fun holding it all together. Holding the plunger from the back side with a pick helped. I did not take the cam plate out because it looks like the governor thing has to come off and it has those odd rounded bolts. I cleaned the housing and reassembled it and it now snaps right over. I have no idea if it would ever work again but maybe when I get some more info I will try getting the pump apart one more stage.

The governor linkage is maddening but I found if turned the pump upside down and tried to put the pump on the cover instead of vise versa, it slipped right on

It is kind of humbling to work on 70's technology and have it be that much of a pain

How do i get the bolt loose on the front of the pump?. It has a slotted collar with a set screw in the middle. It looks like this has to be loosened to allow the flyweight to come off the shaft and allow the front pump to slide out of the bore. Once the flyweight mech is out, how does that large sleeve that sits behind the cam plate come out?
