Brake drum

Item №
28-643
Description
Facts

Reproduction of the brake drums and related parts for swingarm frame Big Twins 1958-72.

Note: due to manufacturing tolerances please check (during assembly) if the brake shoes drag on the inside of the brake drum. In order to avoid machining the brake shoe sides (which of course is possible), place shims like WW 26-901 or WW 27-749 on the rear brake sleeve. This moves the wheel hub and the connected drum to the right and therefore prevents the brake shoe linings from grinding.

  • fits Big Twin 1967-1972
  • rear
  • cast iron, chrome-plated
  • thread: 3/8”-20
  • replaces Harley-Davidson part number 41400-67
  • gross weight: 5 kg
