Broken T-case pics please...

[wehring]

Does anyone have any pics of broken M939 t-cases? I have an interest in building some bolt-on braces but do not have a broken case to use as a guide. If anyone has any broken case housings I would like to get my hands on them.

Here is a couple. Rockwell rates the case at 650 foot pounds of input torque in low range and 7350 input torque in high range. Low range is 1.79 and high range .732 It holds 13.5 pints of oil and weighs 460 pounds. This is the 3rd one in here this year and all broke in the same place.

Please call me. I would like to get my hands on that case so I can make some add-on brackets for support.

it is very understandable if they are using low and reverse and there is high weight and very good traction.

They were 3 trucks that were all stock.

Non were over 20000 pounds. The case is rated at 650 pounds of input torque in low range and that is about all they are good for. They all had good traction in the sand and were stuck at the time and in reverse.
