SOHC Breather and One Way Valve Copper Washer- Pack of 3

Product no.: 0091b E5264-C2

- 1/4" BSP Copper Washer - pack of 3. This washer is suitable for use in 3 places - the Drive Side One Way Valve and the straight through breather or unions fitted to SOHC crankcase fittings and cambox. These washers are not quite as wide as item 0090b, and therefore look less obtrusive when fitted behind these unions (you may decide though you prefer to fit red fibre washers which we also sell). These can also be fitted to 1/4 BSP petrol taps. Sold as a pack of 3

SOHC Crankcase Feed/Return Oil Pipe Union

Crankcase Oil Pipe Union - AF

Product no.: 0246b A11/721-AF

This is the Union that fits into International and SOHC Manx crankcases for both Feed and Return. It allows for the standard 3/8" BSP SOHC Norton oil pipes to be connected. It is very close to original but is a modern item, and uses a larger spanner hex, requiring a UNF spanner. This is a cheaper alternative to the original brass union that I have made specially (Item no 0246), but as you only need to screw it in once this is not really an issue - item is still high quality and is cadmium plated. - Price is per each

SOHC Crankcase Union/Cambox Union/Breather Union (straight thru)

Product no.: 0248b A11/719

This is a faithful reproduction of the straight through union fitted to SOHC (and DOHC) cambox's for connecting the cambox oil feed pipe (fitted at top of crankcase and cambox), but also used as a front crankcase breather on many Inters and magnesium racing engines.  Finally it is also fitted as a breather union on the bevel chamber of magnesium racing crankcases behind the inner timing cover (while Inter crankcases instead employ a pressure telltale unit).  Copied from an original pre-war item

Crankcase Breather (straight thru) - AF

Oil Tank Union (without gauze)

Product no.: 0248d A11\292
This is the oil tank union fitted to many International\Manx oil tanks with the larger 3\8" BSP fitting on both sides (crankcase unions were smaller on the crankcase side). Please note - these do not have gauze filters fitted, which the 'Feed' side union would have had originally (I might make some of these in the future). Gauze can easily be added in by soft soldering.

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
