I have a spare idler pulley set for the M113K engine. The s/c idler pulley is subjected to significant sideways force and this leads to wear on both the bearing and internal wall of the pulley.
Often when you come to replace the bearing a perfect fit can no longer be achieved as the internal wall as worn away.
To combat this I had two sets of idler pulleys sent to a machine shop so the pulleys could be machined out and new harder steel seats could be fitted for the bearings. The bearing where also replaced at the same time.
One of those sets is on my current car and Im having a clear out so would be prepared to sell on the other spare set I had upgraded.
Looking for £190
