pabogala Posted January 30, 2016 Share Posted January 30, 2016 I just got my t-rex engine case covers. I searched and searched and can't find the torque specs for the bolts at the engine case cover. Anyone can help me out here? Link to comment Share on other sites More sharing options...

kakusaizou Posted February 1, 2016 Share Posted February 1, 2016 They are usually torqued at 8ft-lbs. Link to comment Share on other sites More sharing options...
castanzarules Posted February 1, 2016 Share Posted February 1, 2016 I've got a document with all of the FZ chassis torque specs if anyone is interested. I believe I got it from someone else on this forum actually. It doesn't have everything but it has a lot. Link to comment Share on other sites More sharing options...

Shit happens! I just stripped one of them for trying to do everything right. FML... roookiee! any comments, solutions? Link to comment Share on other sites More sharing options...
Guest Ralph Posted February 2, 2016 Share Posted February 2, 2016 The numbers are from the official service manual but like I said I tend to do them by feel, torque wrenches tend to be a little unreliable at such low settings, feel is a thing only experience will give. We used to spend a lot of money with Brigs & Stratton and reps would call when in the UK they could not believe I tightened the big end bolts by feel but tests with their very expensive mini torque wrench showed I was spot on, they must have been impressed as they gave me the wrench, never used it and much to my regret I left it at work when I retired. what you are feeling for is the bolt just starting to stretch don't just tighten one bolt in a case take them all up to snug then nip them up diagonally don't just work your way round a case.

pabogala Posted February 2, 2016 Author Share Posted February 2, 2016 Ok, so I found a possible solution that you guys already might know, it is called helicoil and it is a thread repair kit. I will order it and get it fixed. There is no oil leaking at the time but want to avoid it for whenever I run the motorcycle and oil gets hot.

Yes sir, I am starting to get my own experience I try to read and follow videos before I do any work, I know that to tight engine covers you have to follow the criss cross sequence but crap, this is my second time screwing it up with a damn torque wrench, first time I broke a bolt and now I stripped the thread. That was the last time I use a torque wrench. Link to comment Share on other sites More sharing options...
Guest Ralph Posted February 2, 2016 Share Posted February 2, 2016 Helicoil work well there is also a cheaper Australian I think system that works just as well, cant remember its name once done you are very unlikely to strip one out, I have never seen one fail. Maybe your wrench is out? I have tested a few and some were way off, always brake the wrench a few times before using on anything that matters.

pabogala Posted February 2, 2016 Author Share Posted February 2, 2016 One last thing, I have read in other forums to fix only what gives you problems. Should I just drive it and see if it leaks and if not just leave it that way or go ahead and re thread that sun of a gun? Link to comment Share on other sites More sharing options...
