Has anyone done a 5CP bearing replacment?

[Greg Pack]

I've got a 20 year old 5CP2120 pump with a fresh warranty head and seal kit. and it sounds like the bearing might be going out (I am assuming it's not the motor bearing at this point)

I'm thinking It's best to just replace the pump and salvage the head for spare parts. But before I do that, has anyone bothered putting a new bearing in, and if so is it worth the trouble? KR doesn't even have the part on their website so I'm assuming it's not commonly done.

Thanks

I've never done the bearings on a 5CP pump but I did change the bearing on a 310 pump once. Never again will I do that. Now I call Kleen-Rite and order a 310 crankcase less the head. I've got one now that's banging pretty good that I need to change out.

Yes. Make sure you replace the shaft seal & bearing cover O-ring when you do the work. It's pretty easy. Maybe 20-30min to do both.

Kleen-Rite has it.
