SOHC Crankcase Union/Oil Filter 1/4" BSP Copper Washer - Pack of 3

Product no.: 0090b E5264-C1
- 1/4" BSP Copper Washer - pack of 3. This washer is suitable for use in 3 places - the main Oil pipe unions that screw into the crankcase (see second photograph), the Oil filter bolt that fits at the base of the timing case chamber or the sump plug screw. This washer is annealed (hence the none shiny appearance) and is therefore soft and suitable for this application. It is also slightly wider than normal making it suitable for each of the applications described here. However, for the drive side one way valve, or the straight through breathers/unions fitted to the SOHC Manx timing case, cambox oil pipe or front breather union (if fitted) - you might find the slimmer 0090c E5264-C2 is more suitable (or use an alternative fibre washer). This washer is sold as a pack of 3 (sorry they are not cheap - this is because they are specials and annealed)

SOHC Engine - Complete Cheesehead SS Bar-turned Screw Set

Product no.: 0091 CH HD1
Complete cheesehead screw set for SOHC engine, in stainless steel with red fibre washers - comprising : 18 screws in total - 4 cambox front bevel screws, 6 rear cambox screws, 7 timing case screws, 1 crankcase screw and high quality fibre washer set (including obligatory spare washer!). Update 26/4/14: These cheesehead screws are 'bar-turned' in Stainless Steel, to the same dimensions as the original 1930's/40's Norton items - i.e they are machined from solid bar, rather than being mass produced 'pressed thread' items. The primary reason for doing this is that the 'cheesehead' of Norton screws of this item has a distinctive shape and was slightly wider than the proprietary cheeseheads screws available today (these have width of 0.407", rather than standard width of approx. 0.375"). The set consists of 18 screws. An original NOS (New Old Stock) Norton cheesehead screw was used as a pattern (see photograph 3), these screws copy that profile exactly. Sorry, not cheap as I have these screws machined specially for me from oversize bar

Product no.: 0102 SW002
Used on upright Norton gearbox's, these stainless steel thin width spring washers fit under the blind nut on the front gearbox cover.

Crankcase Breather - Fibre Washer

Product no.: 0249 A11/719FW

Surprisingly it is very difficult to find good quality vulcanised (red fibre) washers to fit 1/4"BSP fittings. These red fibre washers are of the highest quality (from a specialist manufacturer) and have just the right external diameter - but are a very tight fit on the thread. To fit them I place the breather (or similar 1/4" BSP fitting) in soft jaw vice, then place these washers just onto the thread - then I carefully use a pair of large pliers (the circular hole with coarse teeth) to carefully wind them onto the thread. Although this is difficult - the result is the correct size washer that does not look out of place under a Norton breather (unlike many modern ones that are far too wide and look out of place). These are high quality washers from a top manufacturer - sold in pack of 5. Note: do not buy if you are worried you might not be able to fit them!!

Norton Wheel Bearing - Felt Steel Cup

Product no.: 0312 A2/439

I am very pleased to be able to offer this very distinctive steel cup, which is pressed into the end of both front and rear Norton hubs on the brake side, and retains the felt washer, to stop grease escaping into the brake drum. As I am sure many of you have found - even if you have one of these available on your own hub, chances are it will be in bad condition if it has previously been prized out and punched back in, when the wheel bearings were last changed. This pressed cup is high quality and identical to the Norton original that was used as the pattern. To fit, place it above the recess on the brake side of the hub, then use a small punch (or screwdriver) to push it into the recess. If your hub recess is worn, you can also put a couple of additional punch marks on the rim of the hub, as per the plunger hub shown here in the second photograph
