Metal gears for 7x12s
#27
At last I have managed to find the time to get on with the job.

The spindle was removed by the gentle application of a large hammer and a block of wood.
The problem bearing just behind the flange was removed with a 3 leg puller.

   

As recommended, I eased the fit of the bearing and new gear on the shaft, to allow the pre load to be set, but I did not ease the fit of the bearing directly behind the flange as I believe this must be as firm as possible.

So to fit this bearing I warmed the bearing on a hot plate until the oil just started to smoke, then dropped it onto the shaft.

   

   

A perfect fit with no problems

The gears were centralized in the head by rubbing down the spacers on
some wet / dry paper.

   

One thing worthy of a note is that the selector fork is not even, the larger part goes to the bottom.

   

I had to thin down the nuts by 1.5mm each , this was done by assembling the lathe with one nut while I machined the other.

All seems OK so I will wait to see if it makes any difference to the work
