OK so let's start this off by getting some common questions out of the way because there's not a lot of info for M10's in the E30 community and I'm getting sick of doing research and trying to remove this crank pulley off my engine for machining.
The M10 found in 84-85 318i's are not like the M10's found in 2002's, Attempting to remove the crank pulley off the engine can be done with the starter method but if your engine is taken out of the car or you took out your distributor/wiring for a standalone ecu conversion then this method can't work. The Impact method is a solid method but you do need to be careful since the engine still can turn if the flywheel isn't held down by the clutch or a screwdriver. However the impact method can work for removal if you also jam a screwdriver into the flywheel teeth before you go ham on the 30mm Bolt. Installation still requires the usage of a torque wrench set to 120 to 150 pounds respectively, Finally you can lock the flywheel itself with a small tool but this will require removing the bowl reinforcement cover (Part Number: 11141277030) and then the inspection cover to lock down the flywheel with the tool. I originally thought about removing the transmission but that's only if you're also changing the flywheel/replacing the clutch.
So what's all of this for? Essentially I'm going to add information here with pictures once I get the pulley off for machining, If you got pictures and information on how you did it, Drop it here. (M20 folks, please add your own information here as well so it helps out others when they do the crank pulley on the M10 and M20)
