Hi,  I got a new-to-me oil-water pump from a guy I know which I'm going to use to replace the leaking pump on my K75.  I've successfully removed the pump and cover plate from the engine block, however the impeller gear is stuck.  It won't come out with just pulling by hand. I don't want to apply any force at the moment until I confirm how it should be removed.

Question: should this part just pull out of the block or do I have to get into the oil reservoir to release it?

Hi Rob
That guy should just pull straight out - resistance is probably the o-ring.

Cheers SuziQ. I'll use more persuasion.

That thing has been living, on it's own, in the bottom of my box of engine bits for a few years now. Thing is, I have two oil/water pumps in there as well, and they are both complete with those shafts in place. Which is worrying...

Yeah. I had to use the two screwdriver trick to get the last one out. It warn't comin out not no way no other way.
