even without the carrier, the pinion was still binding when the setscrews were tightened. So I took it apart again.
I was thinking of adding a shim on the theory that tightening the setscrews is pushing the retaining ring and the pinion forward, jamming the pinion against the casing.
Compared to another torque tube, there is less of the retaining ring visible in the setscrew holes. That also makes it seem the piston is too deep.
I took it apart originally because there were fragments of the original bushings everywhere, as well as a failed okie bushing.
