Topic: Pesky oil pump shaft seal...

[Sparco195]

Rebuild the oil pump on my 1974 CB750 and I got to the point removing the small oil seal that is inside the pump housing. No matter that I've tried it's not coming out. I've actually ruined the housing trying.

I ordered and used pump off ebay and still have the seal to swap out but I don't want to destroy another one. Is there a special trick to get it out? Do people just leave it alone?

[Sparco195]

It's only my opinion but it seems like it was put in backwards.

The seal lip is facing down towards the inside. I really don't see how to get it out...

Very easy once you know how >>> forums.sohc4.net/index.php/topic,175754.msg2045243.html#msg2045243

Nice job, Trigger! That's simpler than my approach. Gotta go find a tap...

Great idea

Yes, we used to use a tap to pull worn starter bushings on vw engines, etc. works great.

Based on that same concept... wouldn't an appropriately sized easy out work, too?  ("screw extractor")

[Keith]

I think the flat bottom of the tap helps. The tap cuts a thread and pulls the piece upward as it turns. I don’t think the easyout would work as well.
