4x4_Welder Posted May 11, 2006 Share Posted May 11, 2006 I have a project and a spare tranny, so I must ask this question- On an EA-81 d/r 4speed, how much torque can the transmission handle? No shock loading, just constant smooth power. What do you think would break first? Quote Link to comment Share on other sites More sharing options...
jeffast Posted May 11, 2006 Share Posted May 11, 2006 not sure how much it could take but i was told the synchros would fry first Quote Link to comment Share on other sites More sharing options...
mikeshoup Posted May 11, 2006 Share Posted May 11, 2006 I would think the differentials would chip first. Quote Link to comment Share on other sites More sharing options...
4x4_Welder Posted May 12, 2006 Author Share Posted May 12, 2006 Basically, what I need is something to reverse the direction of power, slow the speed down, and split it 90º with a differential. I have an engine and automatic transmission, and I want to hook the output of the auto to the input of the tranny, run it in low range, in reverse, and take power off the axle stubs. The tranny will be locked in reverse, under a plate, with no linkage connected to it. Quote Link to comment Share on other sites More sharing options...
SOOBOUTLAW Posted May 13, 2006 Share Posted May 13, 2006 I've blown two diffs and a transfer case on three separate trannies. Quote Link to comment Share on other sites More sharing options...
4x4_Welder Posted May 14, 2006 Author Share Posted May 14, 2006 Maybe I should just throw this thing together and see if it holds- it'll see some pretty decent stress on it, hoepfully the wheels will slip before it reaches the breaking point if I remember not to overload it. If/when it breaks, it'll be replaced by a Ford 9" diff with 7.30 gears, flipped upside down. Quote Link to comment Share on other sites More sharing options...
