LOCATION: Auckland, New Zealand
LATHE: Maximat V10P (Metric). S/No. C 7404311.
I had just finished boring an opening in 3mm plate and was about to de-burr when I got a sound as if something was winding up and releasing with a spring like effect. My Initial reaction something had got caught in the drive belt. Not so.
I then checked the head stock gears, and all was OK.
While I had not been using the automatic feed, drive was going to the Norton Gear box via the reversing gears. Putting the reversing gears in neutral, enabled the chuck to be freely turned by hand. On further investigation the problem was located in the change speed gear lever and gears of the gearbox.
I suspect that either the ball races or needle rollers have collapsed.
Has anyone had any experience with the Metric Norton gearbox (its detail differs between it, and the Imperial version). Can this lever and shaft be removed without removing the gearbox? It is not absolutely clear from the parts diagram. Has anyone had any experience of what procedure is needed?
Also does anybody have a wiring diagram for the 5 button electrical box? I would just like to have one on hand as I have to re-cable the milling head.
