Hi 951 buddies
I'm replacing belts and rollers on my 951. I decided to reseal the front side of the engine.
There are two issues:

1. Crankshaft: Oilpump gear is stuck and is not moveable
2. from 2 balance shaft housing one (the upper) is not moveable

Did any one ever have problems with getting out one of the two or both?

Any recomandations?
kind regards

They are both "glued" on with loctite 574. Try a little heat.

When I recently did the seals on the front of my engine, the gear was very hard to remove. I could move it a bit but then it would hang up on the shaft. I ended up using some 2000 grit wet sandpaper on the crank, took quite a bit of work to get the surface finish correct to get the gear off.

For the balance shaft housing, you might try hitting it with a rubber mallet on the sides, i.e. top, left, bottom, right and it should break free. A few pictures of the work I did here:

Thank a lot for the Most helpful Information. It is good to know that it May happen that Things don‘t work out as they normale should.

thank you Buddies.

Be very careful not to scratch the shaft. That is where the front seal makes contact and a scratch, even a small one will cause oil to leak from the seal.

****, one time I had to cut the oil pump off the crank because the inner drive gear was so stuck...

but more often they just slide out.

I wonder if antisieze between the gear and the crank snout would help and not hinder?

Heat gun on the gear might help

Comparing our two Situation Mine seems to stick more in the oilpump
