I'm hoping for some old mechanics tips or something here.
As background, I'm running an AHU from a 98 Jetta currently installed in a 91 Jetta. As part of making everything fit, I did an AC delete, and am using a pulley to run the water pump off the serpentine belt, instead of the v-belt.
I'm trying to remove the water pump pulley so I can remove the lower timing belt cover, since the cover does not clear this recessed pulley the way it would clear the original pulley, due to the different offset. I need to get the cover off to check on the crank sprocket, as I suspect it has begun to slip.
I saw in some of the writeups that you can counterhold the pulley with a wrench behind it...but that is the stock pulley. The offset on this pulley does not allow a wrench to fit behind it.
I've tried vice grips, an impact driver, penetrating oils, various combinations of wrenches, but whatever I do the pulley just wants to turn, and I can't get any leverage against the bolts. I've tried with both the belt off and the belt on, but even with the belt on it just slides on the belt. I'm getting close to wrapping a chain wrench around the pulley, but I know this will really scrape up the surface.
If anyone has been in a similar situation, PLEASE let me know how you overcame this problem. I'm afraid to drive the car until I diagnose the crankshaft problem, so I'm stuck driving a beater pickup in the meantime (crappy MPGs)
