Clutch Plate / Slip Disc

Post by neonwall »

Fairly simple Q here however Im don't have a manual and wanting to reinstall clutch on R80 RT 1986. What is the correct orientation of the Slip Disc and what is the correct torque for clutch Bolts?

A couple of images I found are contradictory as attached. Any help appreciated

Aha! I could only see one image previously but now I see that you are referring to the friction disk.

The longer spigot points towards the gearbox. Here you go:

Do you not have a workshop manual? The Clymer manual is a really useful investment, with good step-by-step pictorial guides to almost every procedure and it has all the torque settings and tolerance limits you could ever need:

What's a Nm? :lol: But yes, something like 15 ft-lbs is right.

There are lots of metric conversion web sites available to help determine exact equivalents. Where a torque is given, it's best to assume that trouble will follow if not closely adhered to. I've been using this site for about 15 years....

Scroll down the first page until you get to Torque and there will be all the conversions you'd ever need.

Wobbly -

I was just joshing about Nm...actually that is the site I go to a lot to make my conversions. My memory says that 1 Nm is about 0.7 ft-lbs.
