Lambretta Tool, Final drive (puller) pulling sleeve, MB

It is important when fitting the layshaft and checking the tolerances in the gearbox, that the layshaft is pulled all the way into the rear hub bearing, as far as it will go.

One way is to use a copper/alloy hammer, then fit the rear hub and tighten it up but this can be difficult on the workbench.

As an alternative Mark Broadhurst came up with this sleeve design.

Offer the layshaft into the bearing, fit the sleeve locating the allen screw in the layshaft grooves, fit the special nut provided, hold the sleeve with a spanner and tighten the nut until the layshaft is drawn into position, when it locks up remove the sleeve turn it around and retighten up, Once it locks but the sleeve is loose, undo the nut and turn it around, finally tightening the nut solid.

Ideal to fit the layshaft and keep it tight so the gearbox can be shimmed up correctly.

TIP use some grease on the threads.
