Re: [Healeys] water pump bearings

Hi John,
I sent you a pic separately. the bearing and shaft are one piece on a bj8
pump.
Just rebuilt mine.
Biggest issues are you really need a press to get the brg out of the housing,
and a press to get the impeller off the brg. You can improvise with a vice,
but you run the risk of breaking the impeller. And usually, the back of the
impeller needs to be cleaned up on a lathe where the seal goes.
I rebuilt the old original pump with the grease drilling. All good.
Problem with the new pumps is they are county......
Mike Salter has brgs and seals for bj8 pumps
Best
Chris
PS. Yes Patrick, I took pics and wrote an article for you.... ;-)

housing. The other does not but both shafts with the bearings appear very
similar.

Are the bearings available? Any thoughts on rebuilding the pump?
