Idler pulley broke off
hi all,
I really had no warning this was going to happen, the bolt just snapped after a mile of driving fom my house (I need to drill out the thread which is left)
I need a new bolt and pulley, am I missing any other parts as this is all I could find at the bottom of the engine bay?
I hope ASP can sort me out, does anyone know what the crack is with the bolt breaking?

I checked both bearings, the inside pulley bearing is perfect, the outside pulley bearing has a fair amount of play but turns freely?
I just want to avoid this from happening again. I had driven the car all day and not heard any noises/grinding etc........ the worn bearing vibrating, caused metal fatigue and the bolt gave after time maybe?
I might try and fabricate a support bracket.

I just realise the pulley I need to replace is the 6 ribbed accessory plastic pulley.
I dont think ASP will supply this.
Does anyone no the part number of a pulley I can use, is the W210 E55 the same?
cheers

I searched aimlessly for a replacement plastic pulley, no luck. If you happen to find one, please let me know.
The issue I came across was the plastic pulley was/is only being sold in a package with the SC idler with pricing ranging from 250-500

the original pulley is 90mm ext DIA and 17mm int DIA, I have found/sourced from a local AC DELCO supplier a 6 ribbed pulley which is almost identical, so I have ordered for £16.

Now I have to work out have to take the front engine plate/braket off that holds the other pulleys,alternator,waterpump etc so I can drill out the broken of bolt thread.
OOH and what do you know....... MB doesnt seem to be able to supply me a new bolt as it comes with the idler pulley kit ...........£270

I bet your bolt broke from the heat caused by the outer pulley being worn out.. Now that it is getting hot, I bet we see more stock idler pulley`s fail soon..

I had all those pulley`s made by ASP and bbeen running the them for at least 4K miles.. Very quiet, smooth and no problems at all..

The Plastic pulley I sourced is spot on, I cant belive that MB would not sell me the bolt separately as it only comes with the idler as a full set, typical!
the gap between the two pulleys was very tight and they were almost touching so I have used a 2mm steel washer to keep them apart and not vibrate against each other which might have been the cause of the bolt breaking due to metal fatigue.
also I dont see why it would not be possible or what the issue would be, to have a solid double pulley machined to fit......... both belts spin a the same rate.............do the not?

Bringing this post back from the past. £ C43 £ AMG £ How did the GATES pulley work?
I replaced my accessory belt, as the car was idling the plastic accessory pulley broke tearing apart the new belt. I think the 90,000 miles of engine heat and extra tension the new belt has caused the pulley to disintegrate.
Is there a better way to fix this then spending $400 at stealership? I found many listings on Ebay that appear to sell the plastic accessory pulley only.

This happened to me as well. I replaced the plastic part with a DAYCO 89130 for $25. This part is verified and fits perfectly. http://www.ebay.com/itm/390913099113?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
Now about that bolt.. Does anyone have a source for this? What did you end up going with. I know this thread is pretty old but I'm hoping to get some feedback from someone.
