Well I finally got around to getting some oil and putting the x-feed gearbox/motor back on. I wired the motor directly to an switchable 32A 3 phase feed and turned her on. I was met with a clicking noise and the gear level twitching in time to the clicks. So, I dropped the power and took off the front panel (which holds the hi/lo selector). The oil level sits below the bottom edge, so that was a bonus and when I powered her up again, I was surprised not to see oil splashing out.
With the gears running, I was able to see the problem, the gear that engages the driveshaft is not meshing with the gears, so it is being forced out. This is causing the handle to twitch and the clicking noise (which is the collision of teeth as the gear slips).

Teeth engagement with the power on:
If I hold the gear lever so as to force the gear engagement it works fine but as soon as I let go it slips. I was hoping the shaft holding the gear was eccentric but it isn't.
There is a screw that tightens against the shaft but this is just to stop it from spinning whilst you are trying to tighten the nut that holds it all in place (note the flat on the shaft).
The brass housing that the selector gear rides on is keyed to the selector handle, so it cannot easily be rotated.
One thought was to plug the hole and move it over a few thou. Any thoughts or comments?
