G'day Drew. Probably a silly ? but have you installed the abutment ring (two halves) behind the thrust washer?

Hi Drew,
ring looks like this, and fits in the groove on the gearbox shaft behind the chain wheel

 So just add to Morris, when they arrive, (obviously if in one piece you'll split them) check they fit in the recess in the back of the thrust plate, then hold 'em in place in the groove in the mainshaft with some grease......good luck
