Default Triumph Clutch Center Nut

I'm rebuilding the clutch on the '62 Triumph TR6 650 I just bought and need to know the torque setting for the clutch center nut. I scoured the internet and found a setting of 50 ft lbs for a much older Triumph but that seems likes a lot less than the torque it took to get that nut off.

Try this first

https://www.jockeyjournal.com/forum/s...ad.php?t=57757




Then go here and check the manual for your year.

If you can't find it and nobody posts it before I get to the shop, I'll try and remember to check the book and post it up for you.

Thanks for your quick response. I did several searches of this forum and I have a paper copy of the manual on the classic bike site but neither give the torque setting I need.

I would really appreciate your supplying it if you can find it.

Looks like 50 ft/lbs is correct according to my books.

Now, make sure you post an intro and show us what you're working with. I'm in a good mood this morning so I decided to just give you the info but watch out for Tattoo...he must be sleeping late since he's not here harassing you about an intro himself haha.

Many thanks. I'll use 50 ft lb, bend the washer tabs, and hope I did good.

I just did an intro, so I shouldn't be in too much trouble

50 ft-lbs is good.They used more on a T140,but they were using a bigger thread about then.
Tab washers are almost useless,sometimes worse than useless.I'd leave out the tab washer and just use blue Loctite.

Not to be a dick, but leaving out parts is not what Edward Turner had in mind when his engineers designed motors, etc. Leave it in, even if you think it should not be there.

Edward Turner didn't have Loctite.

The problem with a tab washer is that it's soft.It can crush and you lose tension.Then all comes loose.It can wear after that and get looser.

Carroll Smith gave some good advice in his book "Engineer to Win".Flat hard washers are good.Even no washer is good.Loctite is good.
