| X140 Extract from W.M/441/24.11.13. The road wheels run on the axle tube in a similar manner to our own but the tube is only 2" dia. and the bearings 44" apart. Ordinary self-contained ball bearings are used but appear rather small for the job. The axle shafts and driving dogs for the wheels are in one solid piece and have to be withdrawn to remove the wheel. The inner ends of the axle shafts are hexagonal to take the drive, and the driving ~~clutches are of the~~ dogs have 3 jaws which are a tight fit in the wheel hub jaws. The differential gears are of the spur wheel type, 3 pairs of pinions being used. 5's pitch bevel gears are fitted and the ratio is 22/57 teeth. The axle box appears to be a steel casting and an aluminium cover fitted on top. The differential gear is apparently dropped in through the top and bolted down by two split bearing housings, the axle shafts of course being inserted up the tubes. | ||
