m52 b28 convertion starter motor not meeting up with fly

[gafta]

hello all . im in the process doing a engine swap m42 to m52 b28. ok so im using a m42 gear box m20 flywheel and a m20b25 clutch . looking at quite a few read ups and most folks are saying in order to fit a m20 flywheel to the m52 you will need to get the flywheel machined as it bottoms out on some bolts for the sump?
well today after work before reading that post i managed to fit the flywheel to the m52 and fit the clutch . i offered up the m42 gearbox and bolted it to the block. now as im using a m20 flywheel i also have a m20 starter motor . i placed the starter motor in the correct position and have noticed there is no resistance . on closer inspection the starter motor teeth aint on the ringgear . what am i doing wrong ? help please guys

to some up parts
m20 flywheel
m20 b25 clutch
m20 starter motor
m42 gearbox
m52 b28 e36 block

Is this with no power to the starter motor?
Where have you fitted the round 'spacer' on the flywheel bolts?

The engine and box is out th car the spacer went on after the flywheel .thanks. I did a part number check on the starter it's defiantly a m20 starter .

Back of flywheel normally need to be slightly relieved to clear a couple of sump bolt heads, which is why I asked about the 'spacer'. It's not a spacer at all - it's a load spreader, a sort of joined up set of washers, which goes between the flywheel face and the bolt heads.
If incorrectly fitted, between the crank and the flywheel, it would probably provide the required clearance, but this would be extremely unsafe.
If your flywheel is all bolted up, with the sump in place, and you have clearance, then there is no need to machine your flywheel, but I've no idea why yours is different from others.
If you apply 12 volts to the 6mm terminal on your starter solenoid, then you should see the pinion fly out and engage with the ring gear.

Mr Moore you are spot on . I have removed the gearbox and on closer inspection the fly wheel was up against the sump bolts . Would it be best to remove the rear lip of the fly wheel up to the ring gear ? Cheers and also can I use the m20 b25 clutch bearing ? Thanks
