Hi,
Could you please help in repairing a Gehmann pump which was lying in my club unused for some time. I have to pictures. also I can get all the O rings and silicon grease. My main problem is I am not able to figure out how the pump is fitted to its base.
rgds,
Dileep

First the basic. The V plate screws to the base of the pump using two countersunk screws.
Are those all of the parts that you have?
If you need more pictures just let me know.
Hope this helps

Looking at mine, I get the impression that you have the wrong part screwed into the pump housing.
In mine it's the long shaft that's screwed in the base part, with a brass nut, not that short piece.
Hope this helps

Thanks a lot for reply and pictures.
The base I was mentioning is the one which is attached in this picture.

Here's the exploded diagram of the pump. Did you get the seal kit from Airguns of Arizona? The Gehmann pump is a FX 3 stage pump.
