Raw Water Pump Teardown

I agree with you guys on not using a brass or similar softer metal drift for shaft extraction. I will do differently in the future. For those without an arbor press, here's the method I used to put the shaft/bearings back in the housing. I used long bolts through the flange on the shaft and then used part of a harmonic balancer puller. I went slowly turning each bolt about a 1/4 turn each and pushed it back together nicely. We'll find out how successful this was when I get her out of storage and fired up.

Might be some confusion here. I am suggesting that you DO use a softer metal if you are going to hammer the shaft out.

That's correct. I agree with you. Need to use brass or something softer than stainless.

i just ordered a new one yesterday. so today while i wait for it to be shipped i took the old one apart .just wacked shaft, it slid out , didn't mess with pulling bearings. popped the side cover off the accessible bearing. threw some greae back in it .popped the side cover back on bearing.
put the shaft on a piece of wood. put the body on the bearings put a piece of wood over the end and gave it a couple wacks and she slid home .no need for special tools .unless u are pulling the bearings from the shaft. there isn't much to these things .i wouldn't hesitate to ever rebuild one of these , theres nothing to them. no biggie. i most likely will find some bearings for this old one and keep it for a spare. no need to blow a couple hundred dollars. if ya can change a damper plate , or your old manifolds and risers . to rebuild this pump is a piece of cake.
