Chris, I'm new to Brit classics & I managed it ok- can't remember exactly, but I think you have to take clutch apart, remove primary chaincase, slacken off gearbox & swing it towards engine to allow removal of primary chain, undo the big nut holding the spring/ crankshaft shock absorber assembly & slide it off the splines. There are probably a few tab washers and stuff along the way, but was pretty easy (in my opinion). Can't remember how long it took, but I would guess a couple of hours tops, and that would be with me triple checking everything & carefully laying it all out...

If it is clutch slip, the dome will be hot. If it is the sprocket and sliding member slipping, the clutch dome will be cold.

To clarify, the 1957 on clutches have lining material in the clutch basket, an extra plain plate and a different centre. Mixing components is not going to be immediately obvious.

There's a description here:

Just make sure you've loosened the secondary chain before doing this!

Alternatively you might be able to slide the engine and clutch sprockets off together (leaving the chain joined and the clutch chainwheel and bearing assembled on the carrier that fits over the gearbox mainshaft).

When the friction material is fitted to the outer clutch hub, there are no extra steel plates, but the outer hub acts as an extra friction plate. There are still 4 steel plates and 3 friction plates (except NH which has one less of each )with the back of the outer hub effectivley being the 4th friction plate.The lip at the rear of the inner hub is removed from the 57 on inner hub.

I was wondering if you mixed the new centre (with no lip) with the old basket (with no friction material), whether we thought we might generate slippage.

What does the team think?
