Dear mates

I am doing upgrade on the transmission.
Will put the 13.5g rollers and the crutch spring.
I studied and find the nuts torque as below. Are they correct?
Driving pulley nut (19mm)75-83 NM
Driven pulley nut (19mm) 54-60 NM
Clutch bell nut (34mm) 45-50 NM.

Tons of thanks in advance

It’s more than likely “clutch bell nut” and just mislabeled (that the big 30 something mm one)

I’d say about 20-30 lb/ft, or really as tight as you can get it with pliers and not slipping out of your hands.

If you’ve got the socket? Like, two pneumatic seconds with the rattle gun. Brrrp. Brrrp. Done.

Pay attention, the nut goes on with the little ribs down and the chamfered edges up. And a dab of loc-tite on there too, please.

Inspect and grease everybody while you’re there!

You are right. I should name it clutch assembly nut😅.
Thanks for your instructions.
Can I grease all parts with the rollers grease?

Are you referring to the roller bearings in the clutch centre? If so yes, you can use lithium high melting point bearing grease on those roller bearings but be careful not to over pack those or damage the centre clutch bearing seals as you put the clutch back on the shaft.

As greasy says, no grease whatsoever on the rollers in the variator.

Noted. No grease for the rollers in the variator.
Only apply on the bearings.
Thanks all!!
