Power Seat Coupling Thisis the plasticsafety shear pin that commonly breaks. It is designed to snap if there is too much resistance on the seat track. It is designed to break instead of cracking the plastic transmission housing or straining the motor to a point where it blows the fuse. If you have hit the power seat switch & you hear the motor(s) running but it isn't going any where it is a good chance this has snapped. They are a white plastic that become fragile over the yeras. This new GMpart # 20614175replacement coupling is deisgned to be stronger but still snap in a problem event. It is a much better quality plastic with a higher resin base.
this part is used in the following vehicles but not limited to:

$29.00(NEW GM) Fits all GBodys with power seats. Also fits a wide array of other vehicles. Just take a look at the track. If it has an old hour glass design this should work. There will be 1 single motor. How to Remove and Replace the Power Seat Coupling Sheer Pin.
This is basically and R and R situation. There are 3 7 MM headed screws holding the motor on to the metal frame.
You want to remove the 1 in back first as it is hard to reach. Then the front bottom. Then the top screw.
At this point the motor is loose.
Remove any broken debris from the motor. Cleaning is suggested.
Then remove any broken debris from the transmission, again Cleaning is suggested.
Install the coupling on the motor shaft. The coupling is designed to fit tight. If it was loose it would eventually egg out with use.
Slide motor back in to alignment. The power seat coupling shear pin will have to be rotated to align with the power seat transmission shaft.
Now that you have Both joined together the screw installation can begin.
Install the lower front screw hand tight. Then do the same to the top screw, again just snug so the rear screw will be able to be aligned.
Tighten the rear screw.
Tighten the top front screw. Tighten the Bottom screw.
You have now successfully installed the new power seat coupling shear pin.
Thank you,
