I was wondering if there was a Subaru guru that could answer a question for me.
If you took a 4x4 hi/lo gearbox and put the diff right up as close to the back of the gearbox as you could get it (say allowing 50mm for a coupling) how far apart would the axles stubs be???
I chased up some pics via Google and its looking like using Subaru stuff might put the drive shafts too far apart. So I thought it best to ask.
I got some rough measurements for the later gearbox off a google link, around 620-640 from the drive shafts back to the end of the extension housing. Can anyone confirm??
I was thinking the earlier 4 speed dual range would be perfect for my needs.
Can anyone tell me how long the R160 diff is, front of diff flange to the center of the shafts shafts.
Reason I ask is that I am wanting to make a small tractor type machine with a driven bogey setup. I had toyed with the idea of chain drives as only a diff between each side is really needed, I was thinking of a Renault or VW type transaxle, then I thought of the Subaru drive train. It might actually be a disadvantage having open diffs front and back, I would assume that 4x4 is a locked center arrangement, is that right?? as opposed to the later AWD stuff which apart from the real good gear would be an open center diff.
There will be well less hp going in the front than the standard engine, its looking like 20hp at this stage. It will be reduced down below crank speed (probably about 1/3) so not enough rpm to run an auto I would suspect, just in case anyone was thinking of mentioning it.
550mm is what I am shooting for. Could go 50mm each way. Could probably come in 50mm each end with CV joints.
Given that I sort of have a handle on the gearbox length, going by pics of the diff, it is way too long, Subaru parts might not work out how I had hoped.
Next question would be how much could I take out of the extension housing on the back of a early 4 speed box.
Any help with the above would be appreciated.
Thanks in advance.
