k Series flywheel locking tool.
Can anyone help with advising the best solution regards locking the flywheel / crank, whilst trying to remove the crank pulley nut, on the Rover K Series engine? Does anyone know who produces a locking tool that can be inserted into the ring gear or flywheel on the drivers side engine appature - perhaps Laser Tools, or suchlike? I intend to use an air ratchet gun to spin it off. Any advice appreciated.

Big flat blade screwdriver on the big web at the back of the block. I’ve also used an allan key.

Big screwdriver into teeth. Held that with one hand and pushed the breaker bar with the other.

Same approach but used a piece of flat bar with G Clamp to hold it in place to leave both hands free.

In gear, handbrake on and someone leaning on the footbrake - came undone easily.

An air ratchet won't undo it - an air impact gun might - but just as easy with a breaker bar and a heave.

OK I know I'm in the minority here and I'm about to be shot down by people saying it's always worked for them but I've never liked the idea of trying to wedge something into the flywheel with one hand and swing on a breaker with the other. Maybe you all get away with it but knowing how tight the crank bolt can be to undo, if I was swinging on it and something slipped I don't like the thought of gashing my hand as the breaker gives way (it happened to me once when a cheap breaker snapped the pivot pin and I had a nasty bruise and gash across my wrist).

So I always use a Laser 4523:

It's really designed to be bolted onto the two bolt holes where the bellhousing attached, locking the flywheel from the top, but with the engine in place obviously you can't to do that, but it will fit on the top stud where the starter mounts:

To be honest the stack of washers on the other bolt there was belt and braces and these days I don't bother, if you tighten the top but it has no great urge to go anywhere so long as you make sure that the tooth is properly engaged with the flywheel.

PS: I almost exclusively work on the car on my own so the options involving "getting a mate to" don't work for me.

Well they're not exactly single-use!

In my case that's less then £1 for each time I've used it I'm sure.
