A10 speedometer driveshaft

Does anyone know how to remove the speedometer driveshaft from the outer gearbox casing? I want to get the casing vapour blasted and it cannot stay in place.

My method is to remove the nut (if the type which takes one) remove the retaining screw in the outer cover, attach an old speedo cable to the thread and clamp cable in a vice then gently tap the cover off the speedo bush using a hide or rubber mallet.

Fantastic advice and quick too.  Mine was a little less willing to come out.  The advice gave me confidence to put a ring spanner behind the nut and screw the nut back on.  See photo.  I applied some heat and screwed the nut down.  In fact I ended up with four ring spanner's before the sod was loose enough to pull out.

This will let me take my gearbox casings with the engine casings to get vapour blasted tomorrow.  My engine and gearbox rebuild is gaining momentum.

On stripping I found the interior of the gearbox covered in a waxy grease almost a varnish. All the components were reluctant to move.  Has anyone else found this? 

Any gems of advice for the rebuild?
