Should I get my water pump rebuilt or buy new ?
If rebuilt then any suggestions who can do a good job .
Cheers

I had one rebuilt by a club member on the forum, on going to fit it, it appears that the new one I had fitted previously had possible led to scoring of the block so I have ended up fitting a blanking plate and the EJ ward external electric water pump. Its a good solution but 15 x the price of refurbed water pump. So my refurbed has not been used. Why did I look to replace the new one I had bout from the normal suppliers? Because there are lots of stories of the new ones failing and damaging the J shaft, hence installing a new one as a short term item to be replaced by rebuilt one. happy to discuss further if you wish, John

Last time I looked the new ones were out of stock everywhere.

Seem to be back in stock now.

Faversham installs new ones on all engines they rebuild and I do not think they would risk a warranty claim if they were prone to fail.

Each to his own!

There was a rumour about the hardness of the new pump gear but when tested they were as expected when compared to original

I met Trevor a while back when I was in Kent having a new hood/frame fitted at S.E.T. He has very firm opinions about water pumps and header tanks in Stags. Only the original type water pump in his engines, and definitely no header tanks. He was somewhat dismissive of my external, belt-driven water pump and Volvo header tank!

This is how to check a water pump but it was to late for me when I done this! I could cut it with a small hacksaw, if its been harden I don`t think you can do that?

There are some crappy water pumps still in circulation.

The correct parts to rebuild a pump have (like much other stuff) recently risen in cost dramatically.

The pioneer Weston (oem) seal is now £28 + the dreaded…. Just a few years ago (pre covid) they were £13.

using the best parts available seems to now be about £100 per rebuild…. Just in proper parts.

Cheaper parts are available…. But cannot recommend.

The new pumps seem ok but do have a pressed on impellor.

A pressed on impellor is a bit dubious for rebuilding…. So if I do one I add a grubscrew and loctite.
