Was supposed to just be an oil change on '07.5 Cummins. But I noticed his tensioner pulley had weird "bubbles" and the belt looked questionable.
He leaves for a road trip tomorrow so I opened my big mouth.
I will say, this was one of the bigger PITA serps I've done (that didn't outright require removing the front clip or bend-over mode aka service mode).
Everything wanted to fight me. I finally rigged up a way to pull my serp tool with a ratchet strap to MAX out the tensioner travel and then barely got the belt on.

Weird bumps on old tensioner pulley. Bearing was dry but spun free, like dry skateboard wheels. These bumps left corresponding wear lines in the back (smooth side) of the belt.

I spent WAY too long on a 6.7 belt. If I were flat rate I'd unquestionably be fired. I think I'm just incompetent.....
