Just read that the clutch for an M46 uses a different release bearing to an M46 one, is this correct or not?
Also as far as I know the M46 I have will have a mechanical speedo cable on it, but my 92 240 will have an electronic diff one. Will the spot on the M46 need to be blocked off with something?
Philia_Bear
there are 2-3 types of release bearings
1. Cable clutch
2. Non cable but flat flywheel
3. non cable but dished flywheel

I would suggest tearing your parts car down. Then you can get an idea of what goes where.

Thanks guys, I think I know what I need now.
@Slowbrick I may do that if I have the opportunity.
When ordering new stuff do I need new flywheel bolts and if so how many?
Slowbrick
There are 8 bolts. That being said ive used them numerous times and i still have my legs hahaha

They usually are not an issue, even on trucks we re use them. Flywheel bolts.
Yes there is more than one throwout bearing, early, which is m45, and later, m46 and 47. The pivot height changes between dished and flat flywheel basically.

So basically what I want to buy is a 9" clutch rather than 8.5 because it will work with the dished/stepped flywheel and my M46 will also work with it?
I guess this must mean that the input shaft length is the same with both flat and stepped flywheel?
The other thing is that on the parts car the reverse collar thing is broken so I have to reach under the rubber surround and pull the white lockout thing up manually, to be able to go into reverse. I haven't been able to find the parts necessary to fix this, does anyone have part no's or anything?
Vee_Que
Yes. Buy a dished flywheel kit, everything else is the same.

Currently have an idea of reducing labour costs and also learning something by swapping over the pedal box, and steel firewall plate for the clutch cylinder, myself.
How complex a task is this?
What is involved?
Vee_Que
Pretty easy. you don't need to change the plate if the hole is already in the current firewall plate.
240
There is no hole in the current firewall plate so it'll need to be swapped.
Steering column has to come out presumably?
Vee_Que
I've drilled into one before, not too hard.

Have a look at your firewall plate - in some cases the auto cars came with a grommet and provisions to fit a clutch pedal/master. It is less of a job if you can use your old firewall plate as then you don't have to worry about undoing the steering shaft etc.
240
I thought the steering would have to be moved out of the way anyway to do the pedal box?
The firewall plate is literally just blank, flat steel. I'll take a photo tomorrow in case I'm missing anything but I'm pretty sure there's no hole or anything there already.
I guess drilling is an option but doesn't really seem like the right thing to do compared with swapping over the plates...
Vee_Que
Yeah, it's a similar amount of time.
The pedal box goes in and out without affecting the steering.
Samman88
Drilling is an option but not one that I would personally take, especially if you have one with the holes in it there to swap in! Getting the plate out is not fun as it is on the rear (inside the car) side of the firewall. Once all the bolts are out you have to spin it on the steering shaft untill you can get it through the hole in the firewall, then remove it from the shaft where you split the shaft at the spline in the engine bay.
Hence why I asked if you could use your existing one.

The firewall plate and pedal box is the most shitty/annoying part of the whole job, IMHO.
It's not "hard" as such, but lots of contorting your body and working blind and in confined spaces.
Philia_Bear
The firewall plate is effing easy with a big stepped drill bit and a driver extension to a drill
The pedal is not that hard but involves lying on your back on the door sill hoping another swarm of redbacks don't eat you

Can confirm drilling is not that big of a deal. Thats how we did mine. Id rather drill it than have to get my hands right up behind the dash. That being said, if you arent in a rush and can get in there then I would remove the drivers seat and laying down with a head torch it wouldnt be such a big deal. With the seat in it becomes a matter of how flexible you are.
