I'll give the tensioners the submerged oil test tonight.
ALA - As Long As...
I ordered the later style idlers and 2 new sprockets from Pelican on Wednesday AND there here at my door on Friday.

Good Job Wayne.
I pulled the old idlers out and installed the new sprockets on the new idlers. The sprockets seem to be tight in the idler???
Put the new idlers in (with oil) and pivioted them. Seems that the right one has a momentary bind in it, almost like a notch. Pulled the idler back out and looked at the shaft. Found rust pits on the shaft.
Could that have been causing my noise??
