How to do IMS bearing job without locking crankshaft?

They sell small flywheel locks that bolt into the bell housing and have teeth that locks into the flywheel outer ring (after you set the crank at TDC...)

PS: I would definitely lock the crank (@ TDC) and lock the cams before removing the chain tensioners is not worth taking a chance.

I was thinking of the same thing. However, when you replace IMS bearing, the flywheel is already off. So locking flywheel is not going to work... Have to think of a way to lock the flywheel flange of crankshaft...I'm thinking of bolting 2 flat bars on flywheel flange to bell housing to lock the crankshaft down.... Just an idea...hope it's gonna work...

I don't think that set-up would stop it from moving. remember, even the slightest movement is enough to upset the timing.

If you want to try that route, I'd suggest an L-shaped flat bar, something like a faming square where you can bolt it to, say, A, crank and C. Then another for E, crank and G. This way, it's well-triangulated so it can't rotate.

Good point. I thinking I'm going to do the following
