Decided to sort the leaky water pump on the Stag engined TR. Turned out a lot easier than I thought as I found I could remove the cover and pump without removing the inlet manifold
Try that on a standard engine:P
It turned out the problem was corrosion pitting on the face of the impeller, annoying as it has only been three or four years since it was rebuilt, but as the teeth are perfect I think it is a good candidate for a ceramic insert, I shall have to check LD parts website again, but I shall refurbish it and keep it as a spare.
Since I had an electric water pump left over from when the Sprint engine ate its waterpump and jackshaft a few years ago, I decided to fit that. Stagdad provided me with a bung, and I have spent the weekend replumbing the cooling system to suit.
I have run the pump through a resistor so it only takes 3 amps, this was plenty to cool the sprint engine, and will suffice on the stag engine until we get some hot weather, and I can always change the resistor if needs be. I could always fit a proper controller I suppose, but they are not cheap, so I will see what happens
I also took the oportunity to reseal the leaky left hand cam cover and checked the tappet clearances while I was about it as the fast road cams only use 10 thou clearance on inlet and exhaust, but all was fine in that department
I have a few photos here
