0.265 to 0.334 kg/m (23 to 29 lb/in)
8.
Locate the right-hand back plate and brake assembly to the
axle end, positioning the back plate spacer and insert against the back

10.
Position the hub key in its location and fit the hub.
11.
Secure the hub to the half shaft with the nyloc nut and

12.
Repeat the operations for the left-hand hub, back plate and
brake assembly.
