Is it at all feasible to swap the 85-95 shorter input shaft from an R151F into a 1996+ R151F? Or 96-04 R150F.
I have a 2009 70-Series Land Cruiser's R151F trans and transfer case with the longer input shaft, and am wanting to use a Doomsday Diesel 22R to VW TDI adapter as they clock the TDI over 20 degrees to the passenger side,a HUGE plus trying to fit the tall ALH into a Suzuki/VW/Toyota Samurai build. this moves the oil pan over to the driver's side significantly since it clocks at along the crank axis, and also reduces the overall installation height 2 inches, so you get significantly better Samurai hood clearance or mounting height away from the front diff/high steer. This is also very much preferred for a Toyota solid-axle swap or 79 - 85 Toyota pickup. The ALH does not fit in very well mounted near vertical in those solid-axle front-end applications, but it does fit significantly better when clocked over 20 degrees (valve cover towards passenger side fender, like the native VW installations are typically clocked in VW transverse applications, 12 degrees up to 20 degrees depending on model.
I have two R151F 22RTEC bellhousings.
I have the 1996+ long input shaft trans.
I was slightly concerned about mixing & matching gears from different trannies due to different wear patterns.
I have read that the helix angles on the gears changed at some point, but this may only pertain to the AX15 Jeep version of the R-series trannies, which was 1994 or perhaps 1992 changeover.
I can't swap the entire guts from the 86-87 22RTEC turbo R151F, as I have late model R452 5th gears to swap into the 1996+ R151F, but I should have an entire set of internals from a 86-87 R151F turbo trans on Monday. The 5th gear overdrive upgrade parts that I have do not work on the early transmission internals, however. So in order to keep those for my .695:1 overdrive swap, I have to use the shafts of the 1996+ R-series
