Primary clutch torque?

Question? How many guys actually torque the clutches? I just did mine and 69ft/lbs is effin tight. It feels like you are gonna snap the bolt off by the time it gets torqued. I was just wondering if when you install it the way I used to (impact gun snug) if the clutch would slip on the shaft as it is just a friction fit tapered shaft, therefore resulting in lost power due to slippage? I will find out next time I ride I suppose. Seems to be a valid question as I am sure there are a few guys that are not tightening the clutches properly. Have good day.

Hey Mickey, if you read this perhaps this could be part of my issue?

I don't use a torque wrench, make sure you clean the two mating surfaces off before you do it. I do know if you overtighten it the clutch will hit the thin plate behind the clutch.

Doubt yours is slipping

Todd why do you not torque the clutch shaft bolt, I would have thought that next to head bolts that would be one of the most important ones to torque.

I'm sure there is a great reason to but in seven years of working on UTV's I never have and never had a issue.

Michael has been doing it 13 years and never has.

You need a clutch holder to do it too and we just never bought one.

We do torque head bolts though.

Sometimes around here when someone ask me how tight should something be I tell them to tighten it to 1/4 of a turn before it breaks and I have got some strange looks.

I have had my fair share of machines apart and I never have torqued the clutch and never have I had a problem. I have a cordless mastercraft 1/2" impact and it snap out a whopping 65lbs of torque so I usually rattle the clutch up with it. I just make sure I have a fresh battery in there before I do it.

Well technically I think you are supposed to get it as tight as you possibly can, but be sure not to get it too tight.

I dont think you should have any issue as long as your tourque wrench is right. I have done it both ways... All I will say is when I just used an impact I got it way to tight and could have busted the clutch. So , my two cents is trust the torque wrench.
