1.h Norton SOHC and OHV/SV Petrol and Oil Tank Parts

- Modern Reproduction of the classic 2.5" butterfly filler cap, as used on Norton International oil tanks (as well as pushrod and sidevalve petrol tanks). Notice: 

- Modern Reproduction of the classic 2.5" butterfly filler cap, as used on Norton International and SOHC Manx oil tanks (as well as pushrod and sidevalve petrol tanks). This item is the same as 0120b except it is UK made and of a slightly higher quality than the other type. It comes supplied with rubber seal. I also sell cork style replacement washers (Item 0466) if you prefer to use that type.

Smaller 2" butterfly oil filler cap, as fitted to Norton CS1 (none International) and pushrod/sidevalve Nortons from 1930's through to the 1950's. Comes with cork washer fitted (which many from other sources do not!)

This is a replacement cork sealing washer to fit the 2" butterfly cap fitted to Norton OHV/SV oil tank caps (the caps can be ordered separately - Item 0120c)

This is a replacement cork sealing washer to fit the 2.5" butterfly cap fitted to Norton International/SOHC Manx oil tanks and OHV/SV petrol caps (the caps can be ordered separately - Item 0120b and 0120b_HD).  It is approximately 63mm outer diameter

Cork washer that fits behind hte Chaincase inspection Cover (our Item no 0378). Prevents oil weep down side of chaincase!

These are 4mm internal ID Nitrile O rings and are fitted onto the shaft of the Norton Oilers (Item 0570 and 0571) just under the top brass ferrule, and one is fitted to stop excess oil travelling up the shaft.  These are replacement O rings which can be fitted if the original O ring gets worn, or you damage the original if stripping to clean old castor oil.  The original 'Oilers' were normally fitted wtih a form of rubber/leather washer at the same point - and I would expect that either one or two of these modern O rings would make a good replacement.  Sold as a pack of 3

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

- Good quality Copper washer suitable for 1/4" BSP fittings on most Norton SOHC/OHV/SV engines - i.e. One Way Valves, Breather Unions and Crankcase Oil unions. They can also be fitted to 1/4 BSP petrol taps if required - see listing for details. Sold as a pack of 3

These Red Fibre Washers are a smaller diameter than 'normal' 1/4" BSP washers - but then pre-threaded by us - so they are a good fit on those Norton fittings that used 1/4" BSP thread, but have a groove behind the thread - e.g. Norton pre-48 Oil Sump Plugs and some breather union fittings.  See detail listing for more information.  This listing is for a bag of 5 washers

These Red Fibre Washers are a smaller diameter than 'normal' 1/4" BSP washers - but then pre-threaded by us - so they are a good fit on those Norton fittings that used 1/4" BSP thread, but have a groove behind the thread - e.g. Norton pre-48 Oil Sump Plugs and some breather union fittings.  See detail listing for more information.  This listing is for a pair washers

These Red Fibre Washers are a nice close fit on 1/4" BSP threads and are useful for many Norton fittings - such as those breather unions and petrol taps that have a 1/4" BSP thread that comes up close to the hex or shoulder. Unlike many BSP fibre washers available these days - these ones are a good fit to the thread.  See listing for more information. Price is per pair

Red Fibre washer that fits over most 3/8" BSP Banjo fittings, as well as 3/8" BSP Oil Tank fittings.  These washers are a good 'sized' fit - which is important for getting a good seal. These are sourced from a top quality manufacturer.  Price is for a Pair

- Modern equivelant Dowty washer (outer washer is zinc plated steel, inner washer is neoprene). This washer is used behind the timing chamber filter bolt and also at the back of the rear cylinder crankcase mouth bolt (that has an oil feed)
