[Healeys] Water pump leak

[John Spaur]

If you have a press to remove and reinstall the pulley they are easy to rebuild. The impeller will break if you try to pull or press on it. The impeller is brittle because it is made from unobtainium. I can’t recall if Mike includes the instructions to make a do-it-yourself press but it is simple. You need a flat steel plate about slightly larger than the pulley, drill four oversize holes to match the ones in the pulley. Get a space, such as a socket that is slightly smaller than the end of the water pump shaft. Put it over the end of the shaft and bolt the plate over it onto the pulley. Tighten the bolts in an alternating sequence to press the pulley shaft free from the pulley. When you press the pulley back on don’t press on the impeller, only press on the shaft and pulley. Make a note of the clearance from the impeller to the pump body and the depth of the shaft into the pulley so you can obtain the proper clearances when fitting it all back together.

Look very carefully Keith and you will probably find that the leakage is from the hole in the casting just forward of the gasket. 

That hole is there to allow any coolant that comes past the seal to leak out before it can get into the bearings.

Those pumps are pretty easy to rebuild. The instructions are in the Workshop Manual and I  have a kit for them.
