there is the friction plate with a splined hub in the middle theis sits on the gearbox shaft and the domed coverplate incorporates a spring/s that press the friction plate agaist the flywheel

the bottom of the well is what the clutch mates to, so get all the rust of that. Then there is the raised rim with a further raised bit at the edge clean all that too especially the corner between the flat and the little raised rim- this is the location for the cover, if any crap stops the cover sitting in its rebate clean and square then your going to get judder.

fit the friction plate to the flywheel with the high part of the boss sticking out hold it in place with the clutch alignment tool, then fit the cover plate you have to screw it down gradually against high spring pressure so do it in stages and keep turning the alignment tool so that the friction plate is matched to the spigot hole in the crank. you will need 6 M6 bolts and shakeproof washers make sure the bolts are at least 8.8s (not some crappy "black Iron" stuff for holding wheelbarrows and roof gutters together)

James do note that the heavy flywheels were used on the lower compression engines resulting in torqy running, combined with the old gearboxes meaning you could climb mountains with that set up, ie - on a hill, Hetty will be chugging away in second and you'll be revving your nuts off in first....

So with the heavy wheel on a late engine with a late 'box, I guess you'll gain momentum at the expense of acceleration?

Cheers Paul. I'll take a wire brush on the grinder to it then

Actually answered a lot of questions that where on my mind, can't see how it would be bolted to the flywheel, but I'll wait and see why

Yes saw that in Roy's site, I will probably buy it at L2B and seek Roy's advice there about the centralising tool,

Thanks for the advice, I think I can nail this in te next month or so. I'll wait until after L2B to do it cos I won't need the car after then for a while

Ps, lining up tool? Simple as it sounds?

Sam,
the 'heavy' flywheel/coil spring clutch was fitted right across the range of A series vehicles, also on 652 Visas, until the introduction of the 'light' flywheel/diaphragm clutch in February 1982.

There's also improved smoothness to consider, as well as those other factors you've mentioned.

Ken

Pretty much. Its a stick [plastic] it passes through the clutch friction plate and into a hole [spigot bearing] in the flywheel. It keeps it all in line [centralised] while you bolt the clutch cover [diaphragm] up. Then you take it out. Without using it you will not get the gearbox to connect to the engine.
They do usually supply one with the clutch kit but if they don't any more I am sure someone will lend you one.

Yes to the torque, although you still need to drop the clutch and rev on the hills. I maintain that the heavy flyweel slows down the speed changes placed on the crank. I think that this is a good thing to make the crank last longer.

I'm guessing here but if Citroen had put an external oil filter on the 435cc unit, this would have been practically bomb proof unit.

Is that possible?

Ooh that's a kind offer

Are you at London to Brighton??

Thanks

Some great advice. Thanks. I'll clean it up and report back with a picture.

I'm feelin pretty confident about this, I'll get this cracked easily I recon

I thought 435s did have oil filters, it was 425 that don't?
