Description

This replacement rear axle is the correct fitment for the 1971-1978 BSA and Triumph 650 and 750 twin cylinder models fitted with either conical or disc brake rear hubs. Although it can be used on the later T140 models, this axle is flanged under the head, where the later 37-7113 axle does not have the flange.

The axle, or “spindle” is 5/8″-18 TPI UNF, and measures 11″ OA and 9-7/8″ UH. The original design of the axle was specified for use in the conical rear hub, and it featured a flange under the head of the stationary end of the axle. Sourced from LF Harris in the UK.

The axle is supported by bearings on both sides of the hub and is captured through the adjusters on each slotted end of the swinging arm. When inserted from the drive-side through the hub and speedometer drive, the axle exits through the swinging arm and adjuster on the timing-side and is secured with a locking nut.

The rear wheel must be at the correct level to allow the axle to pass through the swinging arm. A portable jack positioned under the frame is useful for positioning the motorcycle to accept the rear wheel and axle. Refer to the factory workshop for directions on removing and re-installing the rear wheel assembly.

We also offer a premium version of this axle made in 303 Stainless Steel, see recommended links
