Installation notes
The arm is mounted on the threaded shaft of the vacuum motor and secured with the corresponding cap nut (7058965). Ensure correct adjustment of the arm length so that the wiper blade describes the desired sweep angle across the windscreen without touching the rubber seal or frame. Used in combination with 8¼ inch wiper blade with standard hook attachment.
Compatibility
Only for vacuum wiper motors with threaded shaft design. Does NOT fit electric wiper motors or vacuum models with splined shaft. Check before fitting that the motor has a threaded shaft and the corresponding cap nut is available. For vehicles with other motor types, different arms are required.
Historical context
Vacuum windscreen wipers were fitted to many WWII and post-war military vehicles and operated by vacuum from the inlet manifold. The adjustable Trico arm allowed adaptation to different windscreen sizes.
