Norton Chaincase Central Retaining Washer (Stainless Steel)

Product no.: 0380 A2/496
This distinctive heavyweight pressed steel washer retains the Norton pressed steel outer chaincase centrally, in conjunction with the central securing nut (A2/495) which I also hope to offer shortly. It is item No 15 in the second picture, taken from the 48 Spare Parts Catalog) These washers often get distorted over the years, so that the lip is not able to exert full pressure - which in turn means the chaincase is more likely to leak oil. This washer, as well as being an exact copy of the original profile, has a distinct lip which should ensure best chance of ensuring a fully retained chaincase. It is manufactured in stainless steel and polished

Norton - Renolds Primary Chain Half Link

Product no.: 0450 A11/477c
Renolds half link for Norton Primary Chain. First and foremost, I would say it is not considered good practice to fit half (or one and a half) links to primary chains. However, if you find that fitting a different toothed sprocket leaves you with a difficult range of adjustment, then this half link may be used - at least until normal chain stretch allows for it to be removed. Note: these are half links . . . which are quite unusual. It is more usual to fit a 'link and a half' which we also sell seperately. However, these are available if a link and half will result in too long a chain.
