t/a transmission

I posted earlier How does the over run clutche work in relation to the main drive shaft i took it apart last night and any way the trans was not pulling with the t/a not ingaged were can i get new rebuilt kit

This applies only to the mechanical TA, not hydraulic controlled later TA systems.
The OR clutch is designed to allow the whole TA assembly to rotate as a unit in the direction of engine rotation when the TA disk clutch is locked up (engaged) this is direct drive. The power goes from the engine clutch to the TA planetary gears and body of the TA gearbox. This rotation (because the TA disk clutch is locked) drives the housing and gears at the same time. At this time the OR clutch internals are riding along doing nothing.

When the TA lever is pulled back, it releases the TA disk clutch. This allows the TA planetary gears and gear housing to be free from one another. This causws the TA housing to try to turn opposite to the engine direction. The Overrunning clutch stops this motion, transferring the reduction reaction torque to the transmission housing at the rear of the TA.

A parallel to this story is a drill screwdriver attachment that was popular before variable speed drills and cordless reversable drills. It was a fist sized speed reducer and bit holder with two split sections that the operator was to grab with fingers to make the driver turn either forward, or reverse, with much slower speed than the drill motor, and controllable force. Its operation in the forward direction (driving screws) used fingers as the one way clutch, absorbing torque reaction from its internal planetary gears. Also imagine a regular pickup truck stick shift with all the mounting bolts and cross member mounts removed. If put in gear, and the clutch let out, the gear box would rotate, and the PU would not move. I hope this works as an explanation.

We rebuild them if your core is good, email open

can you tell me how much the cost and time or if i can rebuild it my self see i have been working around cars and tractors all my life what would a rebuild kit cost it doesnt look that hard from what i see

I have replacement parts for the t/a and t/a clutch feel free to send me an email. 1 year warranty and 17 years rebuilding.
