Type 9 - input shaft swap (again)
Nitrogeno25 - 5/12/13 at 03:36 PM

I know this was covered in other topics, but my situation is a bit different:

I have one box very well used and another in very good condition but with long input shaft.

The long input shaft box is from a 2.3 V6 (according to the forum) as it has the same ratios as the 2.0 but long input shaft.

Can I just swap the short shaft in the no so good box and use it in the good one?

Any other thing to look for?

Many thanks.

Regards

The 2.8V6 T9 box from the Capri also had a longer input shaft but this has a slightly taller 1st gear ratio than the 2.0 so may not be compatible. This of course could all be cobblers as I am not a gearbox expert....

I undestand that but mine has the same ratios as the 2.0.

As I'm not a gearbox export neither, I'm concerned about swaping parts and specifically gears from one box to another.

Thanks!

Other than the length the 2.3 and standard type 9 input shafts are identical and interchangeable.

The 2.8 one has a different number of teeth and can only be used with the 2.8 lay gear.

Yes you can take it all apart and swap input shafts - I believe the short cut is just to chop the end off with an angle grinder though :-)

Yes indeed you can BUT since the splined section on the V6 box is longer and slightly further forward it can sometimes hit the flywheel/crank before the bellhousing is fully home onto the engine.

Some years ago a track day acquaintance of mine suffered a broken crank. I got press ganged into helping him sort the car (I had the spares he needed) and on striping the engine as well as the broken crank I found the centre main bearing cap etc had snapped out of the block. After we got teh engine rebuilt (replaced actually) I carefully checked clearances on re assembly and found it was a V6 box with a shortened shaft. The spline bit was too far forward and had been pushing the crank forward for several years during which it appeared OK, until it all broke. Solution was to get a short section of the splines ground off at a machine shop
