Info needed on cable shift 901, Someone splain to me in Big Bird terms Options

[mrdezyne]

Lots of good info out there on cable shifters for the 901 and 930 transaxles. I've been trying to keep up with most of them, but I'm having trouble visualizing what has to happen at the tail end of a side shift 901. I've seen several brackets and how the cables are connected but I still don't have a clear picture. Can someone in the know help provide a little insight? Please use small words and lots of pictures.... (IMG:style_emoticons/default/blink.gif)

Let cable shift 101 begin....

There are two movements that need to happen. The shaft on the transmission needs to be pushed in or out to select the pairs of gears, (1-R), (2-3), (4-5) and then the shaft must be rotated clockwise or counter-clockwise to select the actual gear (1,2,3,4,5,R).

So the cable shifter needs to translate the push/pull action of a pair of cables into a rotational motion and a push/pull motion that is probably perpendicular to the way the cable is connected to the transmission.

To complicate things, both motions need to happen without largely affecting one another. That is to say that the rotational motion part cannot interfere with the operation of the push/pull part and vice-versa.

The simplest motion to implement is the rotational. Simply put a lever arm on the shaft and connect the cable to the far end.

In the diagram, the rotational action is shown without the in/out action.

The in/out action is a bit harder to implement because the cable that is responsible for that action must be able to push or pull the shift rod while it is simultaneously rotating. In the case of Bondo's shifter, he uses a lever so that the push-pull cable can enter the assembly from the top. There is no room under the car for a cable to enter unless you are going with a high ride-height.
