    Default Berk Pump...Rebuild or Not???

    Here are pictures of my Berk Pump. Each one is of a different fin. To me they look kinda beat up but I don't have too much to compare to other than pictures of new ones. Engine is still out and I'm leaning more towards pulling this out right now and rebuilding it, but can't get the proper motivation to do the job. What do you think?

    Just have the impeller blades cleaned up, no biggie. No need to buy a new impeller. Jack at MPD cleaned up an impeller for me that hit a rock bar last summer. He did an awesome job on it. It was way worse than the pictures above.

    So if the bowl has any edges that have small dings they need to be smoothed also?

    This.... Pull the bowl and check the impeller/ring.. You wont know till you pull it out.. Rebuild kits with rings are around 200 bucks from any of the site sponsors. I shipped my impeller to HTP and my shaft and bearings to JBP. They cleaned up my stuff and my pump runs worlds better now.

    If the engine is out the rest is a no brainer, not to mention its only dec. So plenty of time for a rebuild.

    I think it would depend. But if one was to pull their bowl and take/post pictures the people in the know would speak up with what needed to be done.

    But until you pull it and post picks its all speculation aint it.

    Likely on any given bowl with some minor "dings and divots", you can "work" the edges with a diegrinder and file. I would agree the impeller above looks pretty grim (especially with the inequity of the leading edges of the blades) , some work cleaning up and indexing the blades may net you some more time out of it but honestly for the price of a new or "reconditioned" impeller I'm not sure I wouldspend the time or the $ to resurrect particular one that one just my 02 ...Tom

    I have no clue on the clearance. Havn't checked anything out other than pulling the inspection hatch.

    Given the responses and PM's, it looks like I'll probably be pulling this thing sometime this week. We'll see how it works out.

    What does one of the pumps weigh anyways?

    Why pull the whole pump. Just pull the bowl impeller and shaft and impeller, they are pretty light.

    then post pics of everything and you will get some good opinions. Then its just a matter of fixing or replacing.

    one good peice of advice. DO NOT buy a rebuild kit until you have decided on what do do with your old impeller. If they are going to resurface it then the ring on the rebuild kit will not be standard. Ask me how i know.
