bluespanner Posted October 28, 2013 Share Posted October 28, 2013 Des anyone know if the output shaft of a 5 speed box is adequate to bolt a flange to, then hang a prop off? How much support does the output shaft have internally? I see that the genuine RWD gearboxes have a different rear housing. Any thoughts? The idea that's pinballing round my brain at the moment is to repower a mk5 transit with an engine and box that doesn't eat fuel pumps, injectors, flywheels, starters, oil pumps, etc etc etc. Quote Link to comment Share on other sites More sharing options...
discomikey Posted October 28, 2013 Share Posted October 28, 2013 The LT77 and R380 (IIRC) were used in rover cars of some description and type, so it must be possible. maybe its worth a google. Quote Link to comment Share on other sites More sharing options...

western Posted October 28, 2013 Share Posted October 28, 2013 both were used in BL/AustinRover/Rover group cars, I don't know what items you would need to make a LR box RWD only. Quote Link to comment Share on other sites More sharing options...
discomikey Posted October 28, 2013 Share Posted October 28, 2013 if the output shaft is supported by a bearing, and sealed from the outside world. surely, as long as you could find a prop flange/ slide on prop joint like the americans quite often have off a gearbox, and you had a way to mount it, (of which there are plenty of ex transfer box stud/threaded holes to use) then it would be ok to use as it is? presuming tranny van handbrakes are on the rear wheels which IIRC they are.

dirtydiesel Posted October 28, 2013 Share Posted October 28, 2013 My brother has a 200tdi in a mk3 transit car transporter, he originally used a sherpa lt77 box. His first box didn't last too long, it kept getting hot and losing oil. We rebuilt the 2wd housing and output shaft onto a early defender lt77 but the top gear wasn't as high as the sherpa box. which made it run even hotter which led to it failing again last week. The reason we reused the tailshaft housing was because the housing has the gearbox mounting in the bottom and the speedo drive in it as well. we are now considering going either to a 2wd converted 200tdi zf auto, or adapting a isuzu box onto the 200tdi. Both of these have nice high 5th gears which will help counteract the 5.14 rear end and 27" tyres Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted October 28, 2013 Share Posted October 28, 2013 The splines on the output shaft are a very long way from the rear most support bearing for the shaft, I cant see them lasting very long with a prop hanging off them. Ashcrofts or AW transmissions might be able to help.. Quote Link to comment Share on other sites More sharing options...
JeffR Posted October 29, 2013 Share Posted October 29, 2013 If my memory is correct, TR7's used the same, albeit, different, gearbox Quote Link to comment Share on other sites More sharing options...
Gremlin Posted October 29, 2013 Share Posted October 29, 2013 Sherpa box is your best bet, but they die behind a tdi, i had one mated to a series transfercase, and i fried the bearings once. Then i killed the output splines, and binned it. I do not recall a support bearing in the tail housing...............but i could be wrong. The output spline is different than the landrover spline for sure (thats why i killed mine) G Quote Link to comment Share on other sites More sharing options...
