BSA Spacer tube, swinging arm
Spacer tube for the rear swinging arm pivot, keeping the arm centered and correctly spaced on its mounting bolt.
This is the spacer tube that fits into the swinging arm pivot on the rear suspension. It sits inside the pivot assembly, keeping the arm centered on its mounting bolt and maintaining the correct spacing between the frame lugs so the arm doesn't bind or wander side to side as it pivots.

The catalog places it under the swinging arm figure alongside centre stand and rear brake control listings, which is where you'd expect a pivot spacer to turn up on the parts diagram. Our records show it appearing in catalog entries from 1969 to 1970.
If you're rebuilding the rear end and the bushings or pivot bolt have seen wear, it's worth checking this tube for scoring or ovaling at the same time, since it rides right there with them. The catalog doesn't tie this part to a specific model, so confirm fitment against your bike before ordering.
