I went and looked again and this time i now see the single set screw on the end of the gear box shaft. the gear box drives the shuttle arm with a slip clutch. the set screw must have been out of sight when we had the faults and never noticed it. When the clutch would slip, it must have hidden this set screw from us allthis time......
i remember trying to tighten the clutch nut to solve our trouble....to no avail.
Pays to just ask here.....i might have to hang out here more often
