Norton Upright Gearbox - Cam Plate or Quadrant Spindle Washer - Pack of Three: these are the special, thick/wide pan washers used to secure the gearbox quadrant and lever arms on all Norton upright gearbox's (1933 type onwards).
I have these washers made specially - they are thicker than any commercially available pan washers and the correct diameter. They are then tumbler deburred to remove sharp edge before going to my platers where they are dull nickel plated (original Norton finished). Hence why the price is more expensive than normal washers!
There are 3 of these per gearbox - two on the main gearbox shell, one of which retains the main gearchange quadrant (shown in photograph) and the other two retain the two quadrant/ratchet levers. Therefore these are sold in a pack of three (and sprayed in duck oil for protection).
The reason it is important to use these correct thick washers, is that they ensure there is no loosening and therefore sideplay of the gearchange levers and quadrant - which gives best chance of clean gearchange.
Hint and tips: If you are experiencing loose or vague gearchanges with your upright Norton gearbox, here are the more obvious things to check:
- Clevis pins or holes on the gearchange quadrant/ratchet levers are worn. We sell new clevis pins (see seperate listings)
- Gearchange positive stop plain bearings are worn or loose - there are two of these in the top of the front gearbox plate one at the back and one at the front they often come loose or get worn - they normally need replacing (I will be offering these shortly)
- These thick washers have been omitted or the bolts are loose and the gearchange levers wobble around
