My 1990 crank pulley is 36 mm.

I have the water pump out without having to remove the crank pulley. My front crank shaft seal appears to be leaking. Is this an easy thing to replace? Any potential gotchas?

I read somewhere that the shaft was splined and the orientation couldn't be messed up, is this true?

What is the best way to remove the pulley? Will regular puller work?

Sorry about all the questions, but I'm not a mechanic and would appreciate some guidance from the bb brain trust!

Thanks.

Brian.

To lock the pulley I used a chain strap wrench around the pulley make sure you bend up the lock tab on the nut, it's a keyway so you do not need a puller or a timing mark. a good 6 point socket and a breaker bar...or just an impact wrench..you could avoid the strap wrench should spin right off... reinstalling with a torque wrench per spec. when removing the seal be careful avoid nicking the seal seat.., reinstalling the seal make certain everything is well cleaned and free of all grit grime, etc. ...I use a block of wood and tap it in across the face of the seal to avoid it racking ...final seating is done with an appropriate sized socket, to make sure it is fully seated.

The older I get.. the faster I was....

well not splined, but it is keyed (woodruff key) where the pulley fits onto, so yes, you can't get it wrong.

see photos from Vin's engine build thread here:

I'd go the few extra bucks and get the Corteco seal....not a job you want to be repeating for a while

also check the pulley once removed if there is any scoring you might want to re-sleeve ii.
