I give up on this pump

biggerred · Dec 4, 2014

Trying to change the seals on this M & W pump I took off a Super M. The front seal is a no brainer but how on earth does this drive cog come off to get to the seal behind it? I also see no seal been the two body sections. (I've got to change the half moon keys holding the gears).

Ya need a special tool and an impact . Tool can be made with some square stock and a big nut and a welder.

I notice that the shift is not threaded. What would an impact wrench do?

I forgot to mention it's keyed.

If it is keyed, it is maybe a press fit. Can you hook a puller jaws behind it?

If it is keyed then it will have to be pulled from first glance i figured that it was a rev. thread .Now as to how much room is behind as to what kind of jaw puller you will need and it should be no less then a three jaw puller .

Should be a small retaining ring next to the shaft rear. Drive dog is supposed to slide off the keyed shaft. Provided my memory is not failing.

Thanks everyone. I'll go the puller route and go from there. Thanks again.

Drive the puller to force the removal. Jim

What is on the reverse side? Any chance of sticking it in a press?
