A comedy of “therefore…” ‘s
They’re in the center of the hanger, which is a threaded rod. The bushings slide down this threaded rod and are pushed/retained/restricted against the Hym joint(the center pivot bit) by nuts.
Therefore, these nuts and everything else on the threaded rod needs to come off in order to slide off the old bushings and slide on the new ones.
If that wasn’t bad enough, this includes the motor plates, which (like everything else) spin off down the threaded rod. However, my motors get in the way of this, both because the wires will get twisted and the motor Cans will hit the deck.
Therefore, the motors need to be removed from the motor plates.
However, the locktited pinions don’t fit through the center slot in the motor plate.
Therefore, I need to remove the pinions with a torch.
Repeat this in reverse for the reassembly, then repeat again for the front.
TLDR; I need to fully rebuild the mechanical drivetrain every time. I’ve done it twice, and it’s a PITA
