The Triumph Dolomite Club - Discussion Forum

I had originally sought a replacement (see wanted section discussion) but thinking I may as well think about reconditioning the existing one first. Background is that this belongs to my 1850 auto project, spun over the engine, which generated enough oil pressure for it to leak (a goodly amount!) of oil through the slot.

I'm guessing £20 for an engineering works to skim the impeller bottom face, but the spindle is a bit cruddy near the water flinger (it's not dirt, corrosion?), which I'll need to remove to change the bearing and oil seal. Everything seems to be in a good condition as such, gear teeth, bearing still smooth, oil seal intact so not sure why it was passing that much oil.

What does collective wisdom say, keep or chuck?

Corrosion on the spindle there is common; you'll be surprised how it cleans up with a bit of emery and the heat you'll need to apply to ease the flinger off.

Definitely needs the impellor machining.

Definitely worth a rebuild, definitely don't throw it away!

Raf, the late great Jonners wrote an article about the water pump. I posted it in the members only section. Should I do the same as what was done with his SU carb article?

EDIT: I've gone ahead and posted a sticky thread HERE

I had Jon's write up as a bookmark long before I even thought about tackling a water pump! Thanks though for highlighting it, and for Alun's reassurance that the one I have is perfectly salvageable. Best get busy and find an engineering place around these parts then.

Thanks!
