gwrightoy Posted February 28, 2018 Share Posted February 28, 2018 Does anyone know what these were for? Part no.1-7-8 FS/MSC 78359 centres 1 ft . 9 1/2" OD. Big and heavy with bronze bush in centres. See photos. Would make an excellent pot stand laid on their flat as they definitely won't blow away 😀Also any one with AEC (possibly matador) can they check any parts books for a new unknown steering worm and nut .Part no.Lv7 FW 2530-99-825-4526.

David Herbert Posted February 28, 2018 Share Posted February 28, 2018 No idea from the part number but it looks like the differential from a small traction engine or a road roller. The brass bush turns freely on the rear axle and the big spur gear that drives it bolts to the outside flange. One big bevel gear is keyed to the axle and that takes the drive to the wheel on the far side of the machine. The other big bevel gear is fixed to the inside of the other wheel and that is free to rotate on the axle. The four holes are there to take a pin that can be inserted through a hole in the wheel that is against the differential. That locks the wheel to the differential assy thus locking the differential.
