I'm in the middle of rebuilding my engine, I put the gearbox in but have replaced bearing and end plate so need to re-shim the gearbox. My hub is off being powder coated. I tried to reassemble it but it locked up when I nipped the endplate down.


If you use one of the spacers instead of a hub to 'pull the layshaft into place' how do you stop the layshaft turning while you tighten down on the spacer?

Just done mine, i built it it up rough to crownwheel then used clutch holding tool to stop gearbox moving, pulled layshaft in then took it all apart and shimmed it, must be a better way but it worked.

2 hub cones small taper to small taper and i hold the layshaft with a glove on my hand or clutch holding tool

What a trick!! But then to undo it... I bet its a real B......!

Cheers to those who offered their help. Now SORTED.

I had tried to tighten down on the layshaft puller tool holding it as suggested, even so the box still would lock down with the end plate not even tight. So I carried on torqued down the endplate, fitted the clutch spider and used the clutch holding tool to lock it all up. To my surprise the hub nut went two full revolutions before tightening down on the puller.

With this done it was just a matter of taking it all apart again and getting the right shim in. With a 2.0mm shim I get 0.08mm, pretty damn good.

Can now hopefully get on with the rest of it.
