Joe Ditchkus Posted January 16, 2016 Share Posted January 16, 2016 I do not know on a Mack but on a Series 60 Detroit they use 1/2" ratchet or breaker bar.

Solution Challenger Posted January 17, 2016 Solution Share Posted January 17, 2016 8mm for the mounting bolt. I break it loose with an allen wrench and small cheater pipe. I cut a 1/2" piece off of the allen wrench, put that piece in a ratchet wrench and use them to remove the bolt. Then reverse order to reinstall the bolt. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/43540-tensioner-pulley/#findComment-320346 Share on other sites More sharing options...
