I finally got tired of going under my truck to lock in the 4wd. Had 2 shift motors go bad on me, and now the module is bad. I can get a 1354M, but I don't have the money right now. I have an extra t-case, some parts, and work is slow as hell. That's when I got to thinkin...
The Plan: Build a setup that utilizes bicycle brake cabes to turn "shift rod"
-I've read too many times the problem with making a linkage is that you can't get a linkage to produce 270* of rotation. A cable wrapped around a pulley will rotate until there is no more cable to pull. Utilizing 2 cables one to engage(green) and one to disengage(red), Also having a pull in both directions will make up for having no detent in 4Hi.
First, I found an Idler pulley (?4.3GM?), I pressed the bearing out of it, then welded it to the gear i pulled out of a bad shift motor.
Notice how the pulley is centered with the dampener bracket. this will allow me to run one cable on each side so that they don't interfere with each other(I had previously removed the dampener from this bracket)
Since the gear just slides onto the shaft, some kind of retainer had to be made. I made this really quickly out of a piece of spring steel I found under my work bench. I then put a little grease in the pulley so it didn't bind. It will most likely get replaced with a better idea.
Need to make the some kind of pulley for the cable. This will do, an air fitting. the cable will rest in the groove
i cut the end off the fitting so that only a little shoulder was left
I then drilled holes in the bracket. put the cut down fittings through, and welded them in.
The grooves on the fittings are actually in line with the outter grooves of the pulley.
Tomarrow, I'm going to the store to buy some cables. Then I'll fab up some adjustable mounts and go from there. It's a start.
