mackaholic Posted February 25, 2006 Share Posted February 25, 2006 If Watts Mack can't find them for you they probably don't exist. I needed a wear ring for an 866 v-8. My local dealer claimed they were no longer available. Not at Watt's. The parts man I talked to went straight to Mack and found one. He did say not to mess it up though as that may be the last one. Oh, by the way, don't remove the wear ring from the crank(if it has one), the new style rear main goes right over it to repair any damage. I think they only used the wear ring stlye in 73' or 74'. Good Luck! Quote Link to comment https://www.bigmacktrucks.com/topic/852-thermodyne-v8-375hp-main-big-end-bearings/#findComment-4337 Share on other sites More sharing options...
