PD: Primary Drive undo ESA PD7

[paw99]

I am surprised to find no help about this in forum. Maybe I am looking wrongly. I got the primary locking device from spares co, but nut still refuses to move.
I would be grateful for a range of solutions, up to the final blowtorch/ grinder methods!
About 35 years since put on.

I use " chain mole grips " and a bit of wood the right height .

Maybe use a blow torch if you put it together with Loctite ?.

If you google mole chain grips ,
Lots around , Machinemart show them, Not the Mole name though.

My problem is not locking the drive, but actually shifting the very tight nut, and maybe the blowtorch will have to be the way.

Heat is your friend

What I like about my idea is it's holding the shaft still,
Some other ways the shocker is going through the motion,
So hard to tell how tight you are going,
Also other ways are straining the shaft in the flywheel fit, So I don't like air hammers etc,
I don't like loctite.

I hand ground the rounded end of my socket flat to get full engagement on the relatively thin hex of the nut.

Bill, for your information the Spares Co tool is a sprocket looking device.

Paw99, heat and a bigger spanner!

Ian , But that will work through the shocker ?.
Sorry not keen on that idea, I can see strain every where.
