This item listing is for a kickstart spring cover of the type that were commonly fitted to early Sturmey Archer gearbox's, with a kickstart shaft of 0.625" diameter. This cover was of a type fitted commonly to Sturmey Archer CS gearbox's on some Norton single cylinder models from the mid 1920's to the early 1930's. These spring covers are machined from solid steel billet/bar - and this listing is non-slotted (i.e. it does not have a slot on its edge for the kickstart spring to feed through - see Item 1246 for the slotted version).
Price is each.
We have copied this cover from an original 1920's Sturmey Archer kickstart spring cover - which probably came from a CS type gearbox, but may have been fitted to other similar Sturmey Archer gearbox's of that period. The original spring cover also had a hole on it outer edge - which was to allow the early type kickcstart spring to protrude through, as they tended to press against the shaft of the kickstart lever.
We have made this spring cover in 2 variations - the type with the hole already cut into the cover (see Item 1247) - and this type, which does not have the hole .. . in case there was a variation we were unaware of, which had an internal spring, or if you want to cut the hole yourself. All other dimensions are identical to Item 1247.
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 the external tang types were of the type commonly fitted with this type of spring cover. 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.
This cover is noticeably different to the later Sturmey kickstart cover we offer (Item 1248 and 1249) in that its centre hole is made for a 0.625" diameter kickstart shaft - as shown in one of the accompanyning photographs, while on later (early 1930's) Sturmey gearbox they moved to a 1" 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.
