So,

I have the 1989 928S4 in the shop for a rebuilt Ac compressor install/ evacuated and recharge and figured I would have them do the accessory belts. I had the belts and figured it would save me some time.

I dont hear from them for a few days...I get a call and they tell me the tech working on the car "nicked" the crankshaft pully changing out the belts and they had to order a new pulley from Germany. Is this the vibration damper.

Im thinking what kind of nic are we talking about here. Is there any thing that I should worry about that they are replacing. Also anything else to address why the pulley/damper is off???

I think I need to take a ride to the shop tomorrow to see for my self the nic.

Pully/damper is that senstive?

Pulley bolts to the front of the damper. It's a drawn steel part that can be nicked/dented/distorted by a "mechanic" who trys to pry the belts off without removing a couple tensioner arms. Be glad they chose to replace it, rather than just try to bang it back into shape. You may want to give them 928 Intl's phone number to get the part in a day rather than a month.

Also--

If they are not aware already, they need to know that the crank bolt needs 218 lbs/ft of torque. There's a special flywheel lock tool to keep the crankshaft from turning. It takes a big bar to get the bolt loose, and a 3/4" drive torque wrench to get the right tightening torque on that bolt. 27mm head on it, by the way.

Actually, I am glad that they are replacing the pulley rather then banging it back into shape. I just figured the pulley would be able to take some abuse. Not much but it must of been one hell of a hit.

Good shop they only work on porschce, audi and mercedes... sounds worse then it is I guess.

thanks

I'll bet they tried to hold the pulley with a wrench to loosen the bolt.

The pulley is thin sheet metal and probably got gouged to hell. Make sure they're using the aforementioned flywheel lock tool rather than trying to loosen the crank bolt some other way.

I'll second that as I had to replace my pulley during a recent TB/WP job because the previous owner or mechanic used a pipe wrench to loosen/tighten the pulley bolt at some point in its life. The pulley grooves were crushed in two spots that led to premature belt wear.

If in doubt, replace the pulley.

what a bunch of dumbass's

They have to loosen the tensioner arms anyway to mount a new belt. WOW, now it cost you a pulley, which yeah isnt the end of the world, but if i were you, that would be the last time i ever went to that garage.

It reminds me of the guy who was doing a 928 TB replacement and decided lets just cut the belt with a razor blade. WHY PEOPLE!

They are eating there mistake soup to nuts. Bet the tech wont do that again!!

And what's wrong with that? As long as it was at the 45 mark on the 32V engines or anywhere else on the 16Vs, it wouldn't matter if he cut it or pulled it off in one piece. Would it?

Just hope they get the big washer on the crank bolt on the right way.

heinrich

agreed

RyanPerrella

well Imo

The guy didnt put it at 45 deg

When I bought it, my '81 had bite marks from a monster pipe wrench on the pulley. Monkey business.
