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!!

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
