Hi,
I've sourced most parts separately so was wanting to check i'm not missing anything when i put it all together. M20B25 engine, b25 gearbox, not sure about clutch plate, flywheel. Think flys are the same - is there a diff between clutch plates?
1) Put spacer (2mm ish) onto crank flange
2) Bolt flywheel with 8 bolts onto crank
3) Align plate and bolt clutch cover to flywheel (6 bolts). I see there three different positions the cover can be mated (i.e. every 120deg). Presume any of these will do?
4) Release bearing into gearbox with release arm in position over it, attached on one side with clip.
5) Shielding plate that goes around the crank etc, is this bolted to box then engine or vice versa?
6) Bolt box up to engine. I've got some torx bolts, 7 i think of various sizes, does anyone know if the rest are just standard bolts? how many in total? Use washers with torx bolts?
Have I missed anything? I see on some photos people have a plate bolted onto the flywheel but don't see what thats for!
Cheers
Gearbox, clutch, flywheel, engine assembly?

well point one you are putting the spacer the wrong side as its not a spacer its a big washer.
The sheild that goes between the gear box and the engine has to go on the engine side first.
Once you start putting it all together it will all come clear.

Check that the crank has a bearing fitted into the end of it to take the end of the gearbox input shaft, and that it has the correct size inner race.
This bearing isn't fitted on engines that came from autos, and there was a change in the input shaft end diameter at some time.
