My '63 1200 Herald

[Daves 63 1200]

Newbie from Kent. Bought my Herald 5 weeks ago, covered over 1000 miles of trouble free daily commuting. At 1001 miles the clutch started to slip so the mission began to see whats what.

After removal of passenger seat, carpet and tunnel cover the box came out through the door. This was when I realised this was no ordinary clutch. It had 9 what appeared to be valve springs on the outside of the cover ???.

What is required to convert to "standard" style clutch? flywheel? slave? fork? I purchased clutch online and now have standard clutch.

I also have a set of Revolution wheels to fit, 6j x 13  but no nuts. Do i go longer standard studs or longer metric?

Many thanks in advance Dave.

a quick  look on clutches at  rimmers shows the engine numbers when the 9 coil spring clutch was updated to a diaphragm cover

you will need a GRB207 throwout bearing

see https://www.rimmerbros.co.uk/Item--i-GRID005175

 

and you should change the 0.75 dia slave for a 0.875" dia slave

see   eg.   https://www.rimmerbros.co.uk/Item--i-GRID005177

Thanks Pete. Rimmers told me they no longer stock the 9 spring. Would need a later flywheel. Cant remember what mine looked like as there are two different ones on Ebay. Newer cover bolt holes dont line up on my flywheel.

Do the dowels align ok? 

 If they do its Easy to drill and tap new holes by hand or bench drill and tap

As you have located an Easy option is get a used from where ever .

Nothing aligns. Later flywheel it is, as already have clutch kit from James Paddock along with some other bits.
