I've tried to rebuild two water pumps with the same thought as Ken, but
neither attempt was successful.B  The cast iron vanes broke both times I tried
to press them off the shaft.B  I also know that others found out they don't
always go back together the way they hoped; once taken off the shaft the cast
piece is not as tight when put back on and it will shortly tear the pump
apart, hit the housing and wreck it too. On the whole, not many good options
for these pumps.B

I know you have a Stag as well and may be familiar with LDParts in the UK.
Pete Howell, the owner, says not to trust "new" water pumps, as you don't
know where they're made. If the teeth are fine, just rebuild the old one.
He has a kit.

I know the shaft went on my Dolly Sprint a few years ago and a "new"
replacement (actually from Robsport) failed after just 70 miles.

So, no matter if it's a Dolomite, Sprint, TR7 or Stag, I would try and just
replace the bearing if the shaft isn't too bad.

Cheers
