DIFFERENTIAL-GEARING

This is a top-drive differential, so the input shaft and all the gears that drive the differential are attached to the cover. Using a chain fall attached to the roof of the Futurliner they were able to lift this 400 lb. assembly vertically. Next, they attached this assembly to an engine hoist that was positioned outside of the Futurliner. Once everything was firmly chained to the engine hoist it was backed away from the Futurliner and differential-gearing assembly was lowered to the floor. It appears that the gearing ratio of this differential is someplace between 16:1 and 24:1.

Using a chain-fall attached to the roof of the Futurliner the 400 lb. differential is hoisted up through the floor.

Del Carpenter and Basil Lewis attach the differential to a engine hoist and back away from the Futurliner.

It appears that the gearing ratio of the differential is someplace between 16:1 and 24:1. Next comes the disassembly of this assembly and replacement of bad bearings and parts.

Here we see the freshly primed differential and a support bracket hanging from the engine hoist. They have been refurbished and await installation.
