Cheers, I'm planning to replace the ring gear, apparently the centre boss is keyed to the shaft.
When I get this drive working will be continuing to renovate this machine but will stop short of painting it.
New soleplate, front roller end caps, new bearings throughout, clutch cable and cutter blade regrind all on the agenda.
But firstly need to restore the drive.

PS Have now got the ring gear off but not the boss, and have new ring gear on order.
What I think was happening to make me lose drive was the ring gear was slipping on the boss, which was why with the rollers lifted she would drive but when the weight was on the rollers the ring gear slipped on the boss.

New ring gear should be here by next week so have till then to remove the boss, which according to TMS might not be easy.
Okay, off to get the blow torch and try some heat to expand it.
