This item listing is for a kickstart spring cover of the type that were commonly fitted to later Sturmey Archer gearbox's, with a kickstart shaft of 1.00" diameter. This cover was of a type fitted commonly to Sturmey Archer 3 speed and later 4 speed gearbox's, probably late 1920's - early 1930's.
This particularl type has no hole on its lip - and is of the type likely to be fitted to later Sturmey Archer gearboxs that have an internal spring tang (i.e. our item 1066) - see photographs attached of gearbox's of this type (we also sell a similar cover, with hole in it for an external tang spring - our Item 01247).
Price is each.
We have copied this cover from an original Sturmey Archer kickstart spring cover - and that can be seen in the photographs. We have copied the dimensions from that. Becasue there were (seemingly) so many variations of Sturmey Archer gearbox's - fitted to many makes, as well as Norton's, if not entirely sure - we would recommend you email us on paul.norman@racingvincent.co.uk and we can confirm dimensions - particularly the interal diameter of the main body (that would normally slide over a lip on the gearbox cover) and the depth.
If you look in the same section as this spring cover listing - you will also see that we sell a variety of Sturmey Archer kickstart springs - and we would expect this cover was used mainly with our spring type - Item 1066.
However, because of the number of small Sturmey Archer gearbox variations in that period - please email me on paul.norman@racingvincent.co.uk if you wish to check dimensions - particularly the inner bore diameter of the cover, and the depth . . . which may vary on other Sturmey Archer gearbox's.
Please Note: I have seen in pictures, variations of later Norton Sturmey Archer gearboxis (i.e. 32-33), where the kickstart spring cover looks to have an additional lip around its outer face - these covers do not have that - they are exactly as they look in the photographs - so please check with us if you are not sure if you have that type of gearbox before ordering.
This cover is noticeably different to the other Sturmey kickstart cover we offer (Item 1246 and 1247) in that its centre hole is made for a 1.00" diameter kickstart shaft - as shown in one of the accompanyning photographs, while on the other (CS type?) Sturmey gearbox they used a 0.625" shaft.
These kickstart spring covers are now extremely rare to find - and normally heavily dented and damaged. We have only made a small batch of these, but because of the prohibitive cost of having press tooling made (we have been quoted @£2k) . . .instead, we have had small batch's machined from solid billet/bar. Because of this, hope you will understand why they are not as cheap as a mass produced item.
