First I pulled with my Olympic arm wrestling hands, then pried with a screw driver, then I pried with a cats paw, then a hammer and crow bar. NOTHING!
Then I decided its power tool time! Got out the grinder and cut away the pump. Finally I was able to rip off all the existing pump and rust.
BUT.....In the process it looks like I damaged the front of the motor (see in attached photo #1).
My Questions are:
1) Can I still use this motor? Picture #1 (3363736) It looks sketchy....
2) Is my other motor (8528157) compatible? They look like the same exact motor?
3) Are there any more efficient ways of removing a rusty pump from the driveshaft other than brute force?
4) Is there anything you can put on the driveshaft/pump interface to avoid rust build up?
