Mike,

Looks great clean.

Get that 915 gearbox apart asap. The pressure washer will force water past the differential (axle flange) seals and, if left for any length of time, damage the big tapered roller bearings that support the differential and ring gear. Of course it can get in all sorts of other places – past other seals, breather. The seals are designed to keep oil from leaking out, not high pressure water from getting in.

Please get it completely disassembled, hot, dry and re-lubricated. Water in hidden places in a transmission spells D-E-A-T-H.


That gear looks like part of a fixed 2nd gear. This transmission is going to need some VERY careful inspection. I’ll bet the bearings that support the input shaft and pinion shaft in the main differential casting are now slip-fit at best.

Please give us a blow-by-blow description of what you find.

Best,
Grady
