    Default Sherwood E35 - graphite bushing removal?

    I'm doing a major rebuild on an E-35. How are you guys removing the old graphite bushing so that you can replace it? I thought I could drill it out on my drill press but it's an odd size. Hammer/chisel and break it?

    thanks
    Bob

    Bob, perhaps find a machine shop who owns a dead-end or blind-bore collect and slide-hammer style bushing puller.

    Apply some heat to the housing as to mildly expand it a bit.

    Better yet, replace the E-35 with a Johnson F5B-9 or F6B-9 crankshaft style seawater pump!

    around here, most drill thru the side of the bushing, on either end of a diameter, and then shatter the rest of the bushing so it comes out in pieces....

    Thanks, thatís basically what I wound up doing. The bushings shatter pretty easily so it only takes a few minutes. Funny, this
    is pretty well hidden information for such a common pump. I have another one on the bench to rebuild so I think Iíll do a youtube video.

    Ricardo, unfortunately not enough clearance for any other style pump

    Even the Sherwood tech data I have is silent on the removal of the bushing....they pretty well cover the installation but don't say anything on the extraction process...

    Mark, after having searched myself, I came up with the same assessment.

    Odd!

    Took one out today. Fill the bearing with heavy grease then use a 5/8" shaft and a hammer. Put shaft into bushing as far as you can and rap it with the hammer. May need to add grease as the bushing comes out.

    I always found it easier to press them in....the are brittle and won't take much abuse...

    I agree when putting them in..once moving dont stop. I cracked a brand new one stopping halfway installed. I was talking about taking them out with the grease.

    Just a suggestion:

    When installing friction fit (or interference) items, such as this bushing, cool the bushing and apply mild heat to the receiving part.
    You will be surprised at how much a bit of contraction and expansion helps the installation.

    Understand - just wanted to make sure the thought that came to mind was shared for Bob's potential benefit.

    Honestly, I never thought about your hydraulic extraction process for this particular piece - every one I've taken out was already 'condemned', so its destruction was a given.

    guys, any tips on how to press in the bushing without a fancy slide hammer? like a piece of pvc or socket wrench socket or something? Also, do I grease it first? With what.... oh, and the new impeller, what do I grease that with, if anything? And finally, what about the gasket? treat with anything? Sorry for all the dumb questions. It's my first rebuild.

    Rather than Hy-Jacking an old thread (this one is well over a year old), I would suggest starting a new thread for your specific question.
