901 swap Q
 

the shift rod part of the conversion has always made me feel a little unsure about the conversion.

Most or all of the conversion things ive read for this swap mention bending/welding/lengthening the shift rod etc.

But if its bent, i dont see how it turns the shaft on the tranny???(the side to side motion on the shift pattern, the neutral area)the clockwise/countercw motion of the shaft.

i would think there would be a necessity for 2 couplers or u joints at the bends in order to keep a smooth shifting tranny.

but, if theres 2, then you wont be able to shift, the joints will just flex.


The only way i can think to correct this is to Not bend the shaft, but instead angle the whole shaft, but im not sure how much it would affect shifting.

heres a quick sketch of what i mean about the bent rods

u can easily see that the wide angle the bent rod swings at vs the stock one.

heres a sketch that shows angling the whole rod

any input/suggestions appreciated.

Hi,

exactly that´s one of the reasons, why I engineered a shifter with a lowered shifting rod. The system withg the bend rod is working, but it´s not working so very well, as there is always some pressure on the bushing. The reason for this is, that the bend rod wants to make a bigger circle in the back of the car. As it is fixxed to the gearbox it can not do this circular movement. That causes pressure on the bushings and makes the shifting a harder work and by this more and more less exact.
On my system the shift rod is lowered to the ground of the tunnel and is going straight to the back of the car. Besides my shifter only has a shift ratio of 55 mm per gear and is very precise and secure to shift. Have a look on my site and follow this link www.bugat5speed.de/cms/content/view/115/52/.

If you´ve got questions, please contact me.

I've done the 2 cardin joint setup to mine. It works perfectly. Almost TOO smooth.

Sandeep has done the same thing, but with different parts.

Do u have pics of yours or sandeeps setup?
