[Healeys] Locking Crank

[Michael Salter]

The factory tool was a "slugging wrench", pic attached.
The rotating assembly of a Healey engine has significant inertia so using this tool precludes the necessity to "lock" it.

If(!) my memory t serves me right, you can take the sump off and jam it with a piece of wood.

Otherwise, maybe get something to lock the flywheel. Per attached. I used this for work on the clutch but should do the job?

Years ago, I put a massive spanner on the nut and clouted it with a big hammer. Yes, the crank moved but the nut surely tightened up. It is an absolute beast of a spanner…open-ended, just one end. Heavy as anything, looks like something out of a Challenger tank’s toolkit.

Have fun. Simon

Had a bit of a mishap with my BJ8 engine that is installed in the car.

Drive shaft and gearbox in place and tunnel off.

Need to re-tighten the crank nut.

So how is the easiest way to lock the crank ?

Is it safe (no damage) to lock the prop shaft flange and in 4th gear ?

Thank you
