XUD9 to EW10 conversion

[MattBLancs]

Here's the thread, short version is 2.2 HDi gearbox does not fit 2.0 8 valve HDi as fitted to 306

Certain ml6 will bolt to dw10 (8v HDi)

But physically the 6 speed 2.2 I had, box would not fit the 8v block

To be honest, I think looking at the pictures is good but a bit risky!

Am sure I have read DW10 and DW12 are different sized bellhousings - pattern the same, but the overall spacing of the bolts was larger. (Will try and find the thread on it)

Am also worried quite how different the gearbox input shafts look, here's a zoomed in view from your image:

Splined area looks massive!

Agreed, it looks massive, but I was doing some investigation about it, took luk and sachs catalog and did a little cross reference

JPX/504 uses a Ø215mm disc, with 10 straight splines. Pressure plate uses 6 bolts
This was a very common spline for light trucks, my other jeep uses a clark 240V trans is similar, GM S10 to

EW10A/EW10J4/DW10TD/EW7J4/XU7JP4 uses the same Ø230mm disc 18 splines with the BE3R | BE4R | BE4/5 | BE3/5

Both XUD and EW10A used the same BE4R transmission, maybe with a different splined input shaft

I like the XUD9 because I won't need to adapt a thing, just rebuild it. But it will probably cost the same as an used EW10A. I Like the XUD9 because seams to be a very fuel economic engine

I like the EW10A because they're plenty available from various donors, will work with a stock ECU, has more torque and power than a stock XUD9, is a more modern engine and lighter.

This guy swap a 2.0HDI (DW10?) to a XUD9, looks totally plug and play
