I actually talked to Wagler last week about a belt problem and they told me they are currently in the process of having a tensioner finished for the lb7’s soonWondering if anyone knows why the Wagler mechanical belt tensioner won't work for an LB7 but an oem one will for for 02-10 model year duramax engines..?
Anyone know if there's any other companies making one? tired of belts getting shredded.
I spoke With Austin a while ago when they first released them and he said they would have them for the lb7s shortly after the new year but ya..... still waiting Hahahah (hate waiting).....I actually talked to Wagler last week about a belt problem and they told me they are currently in the process of having a tensioner finished for the lb7’s soon
Good point here. I’m also curious if what they come up with will work on 01 lb7 since they have the unique tensioner.my only thought would be that the idler pulleys are in a different location on LB7 so the tensioner may interfere with the LB7 idlers or may not have enough throw.
Be aware that you either need to mod the bracket to accept the LB7 CCV or you have to remake your CCV. I do not know if the LLY bracketry is a different offset than LB7 but that would be another thing to check to make sure the belt runs true.I was thinking of using an lly alternator bracket and if the idle puller is in a different spot i think routing the belt differently.
I haven't had any belt shift since getting their tensioner. I'm not saying their tensioner is the "be-all-end-all", but some form of rigid tensioner is what these trucks need with RPM and dual pumps. The factory tensioner doesn't seem to have enough force.I ordered one last night. . Pricey but if it works and keeps the belt from jumping ribs and keeps it on it will be worth it .
I know the feeling. My comment about making your own was pointed at the LB7 guys due to availability from Wagler.I too fabricate a lot of my own stuff but sometimes you have more time than money then sometimes it’s like now where I have more money than time . :thumb:
