Dear Tom,
Good p.m. and may this find you well. Good advice, whc. should be added to the FAQs.
Just heard from my nephew, who completed the job (we lacked a grommet for the pipe from waterpump to heater control valve, new alternator bushings, and a new alternator belt tensioner).
All parts went in fine. The water pump does not leak. Apparently I seated the balancer correctly. The distance from the front of the timing belt case to the front of the balancer is 2 1/8" =/- 1/32". This is the same as on my 940s, which have the factory-original balancers.
I used acetone to clean the crankshaft end, block face's water pump sealing surfaces, the wells into which the crank, cam, and intermediate seals are seated, and the timing belt tensioner stud's recess. This way, we made sure to remove all contaminants.
We lubricated the seals with an emulsion of grease and motor oil. We improvised a seating tool for the crank seal, and turned the crank bolt to press the seal into place. I will make one out of 2" diameter Schedule 40 PVC pipe: it is the perfect diameter.
How are your kids' cars doing?
Yours faithfully,
spook
