Re: z750L: Repair starter clutch
08 Jul 2025 22:59Then you need a clutch holder, trying to hold the clutch any other way will likely result in damage (I assume you span it off with an air-gun etc)I saw the same tips in the service guide made by a user on the forum, but when it's set in 1st gear, it will spin, since I don’t have any friction plate or springs installed… No clutch is installed, right?You can try putting it in 1st gear and get someone to apply the rear brake while you torque the nut. Correct torque is important
A razor blade will work but be careful not to damage the surface
I feel that is something stupid I don`t understand here![]()

Re: z750L: Repair starter clutch
08 Jul 2025 23:15I was doing some quick research, and others recommend using a torque stick. I think that would be better value for money, since I can use it for other activities later as well.Then you need a clutch holder, trying to hold the clutch any other way will likely result in damage (I assume you span it off with an air-gun etc)I saw the same tips in the service guide made by a user on the forum, but when it's set in 1st gear, it will spin, since I don’t have any friction plate or springs installed… No clutch is installed, right?You can try putting it in 1st gear and get someone to apply the rear brake while you torque the nut.

I found a kit in Norway: Momentstaver, 5 stk. - Biltema.no
If I remember correct the service manual said 100-160Nm.

Yes, Torque Stick, and Impact gun. Quick, no drama, and no help needed. That is what I used.

How much should I torque the bolts that hold the pressure plate on the clutch? The bolts with the spring behind them?

Clutch Hub lockout - 132.39 Nm
Clutch spring bolt - 8.83 Nm
I found the Clutch Hub lockout in my service manual where it gave me a range off 108-160 Nm (80-118 ft.lbs), but I will torque it to around 133 Nm than.
