Just done mine for the second time as the first replacement mast lasted only a month before the drive pulled out of the mast, the seller sent me another one FOC.

What I did was remove the toothed drive as you did by stripping down the motor gearbox but instead of following the instructions on LexLS to manually wind in the new drive I got hold of 2 spade tags and a bits of wire on the motor and then used a spare car Battery to wind the new drive into the gearbox which gave me more control.

Popped it back in position and all working fine again.

I would at least be looking for either a free replacement or a full refund.
