Norton Clutch Plates - Friction (none Sureflex)

Product no.: 0254 A2/393b
These friction clutch plates are the same fitting as the Sureflex plates, but are manufactured by my offshore 'cheap and cheerful' manufacturer (who make lots of clutch plates for all kind of British bikes). As at 2/3/14 I have not tried these myself yet, but they look well made and the friction material is bonded to the plate (as with Sureflex) and looks quite similar to the original Norton friction material in composition. In summary, if you want the best - then go sureflex, but if want to try a cheaper alternative that look to offer good value for money, then try these (I will be doing that myself shortly!)

Upright Gearbox Clutch Worm Lever Arm and Bolt

Product no.: 0418 A2/377+378
This is a faithful reproduction of the Clutch Worm Lever Arm and the special 'reduced head' bolt that is fitted to all Norton upright gearbox's from early 1930's to 1950. It slides over the the eccentric worm spindle and can be adjusted then locked to maintain the correct tension of the clutch lever cable. Both the arm and the special reduced head bolt are faithful copies of the original Norton items, and if I say so myself look really nice quality. The casting is a 'Lost Wax' casting, the patterns been copied from an original arm - lost wax giving a finer finish than a sand casting (but more expensive to reproduce). The reduced head bolt is also identical, and matched to the arm, including the shouldered face that matchs the coutersink in the arm. The only variation from original is that they are both manufactured in stainless steel, with the arm having a satin finish similar to an original. They are the finishing touch to a pre-war Norton gearbox restoration (and look great when also fitted with our stainless end nuts) - particularly as originals are now getting extremely hard to find. The second photograph shows an original arm fitted to a Manx gearbox, so you can see that ours are identical! (note the same arm is also employed on the SOHC exhaust lifter, although Norton gave them a different reference number!). Sorry they are not cheap, but the price reflects the high cost of having patterns made for casting the arm and the expense of lost wax castings

Norton AMC Type Gear Lever

Product no.: 0421 D12/406b

It was fitted to late Norton DOHC Manx and Norton Domintaor's.
