Jangy's Tuner lesson




The answer is - Very, very likely.
If you can visibly see pulley wobbling it means that it is at the edge of the woodruff key and it is grinding at the end of the crankshaft.
If you are lucky the key is repairable.
If not, you will need a new crank. Around $15,000 parts and labor.
Scenario #1: Original bolt has been reused. If it is the case, than it has already been stretched and will not provide adequate force to keep pulley in place.
Scenario #2: New bolt, but it has not been installed correctly. Proper installation requires torque-angle gauge. It is somewhat dificult to use on the crank due to the location and many shops and "wanna-be mechanics" just "wing it".

The result is loose bolt and pulley sliding off.
Now to the question of the day - Is there a damage to the crank?
The answer is - Very, very likely.

Installing crank pulley on the Kompressor motors is somewhat delicate procedure. Woodruff key is behind the front cover and is almost impossible to see. One has to go by feel as pulley is slid on the end of the crank and it's proper position is verified against other pulleys.
My best wishes to you my friend.
Why does the stock pulley appear to be one piece and the Kleeman appears to be a slipped and keyed affair?
Thanks
wow! not stoking any fires but a bolt falling out after only 12 hours to me at least, sounds like the pulley wasnt seated all the way. than the bolt was torqued to the unseated position. or not torqued to the specs which is degrees of angle first than ft lbs i believe.
you can go to alldata.com and buy a 1 year subscription for your car for $25. its for mechanics and tells them how to work on your car such as correct pulley installation fyi.
renntech uses the factory pulley damper/dampener the presses a larger outer ring pulley so i seriously doubt it is a pulley problem but thats my .02c.
My best wishes to you my friend.
IMHO As soon as I heard the sound/felt something wrong I would have had the car flatbedded to MBLN or Fletcher Jones or whatever is closest to the Toll Road. Have a certified MB tech look at it instead of tightening down the pulley.
Good luck with the car bro.
