Magneto Chain Soft (Rivetable) Link (Renolds)

Product no.: 0394 A11/113R
This item is a Renolds 'soft' link to fit a magneto chain. This type of rivetable link is always preferable to a 'split' type link and would have been fitted orignally. These can be fiddly to fit, but the normal process is to fit the soft link, ensuring the back plate of the soft link is resting against a firm metal surface, then use a punch and small hammer to peen the end of the soft link pins so that the outer plate cannot come off. The end of these pins are unhardened for this purpose. It is not unusual to find that once this has been done the result is this link becomes a 'tight' spot on the chain, in which case give it may required slight tweaking and movement to restore full movement. Each chain comes supplied with a soft link, but if you feel you have damaged the link supplied (i.e. hit it too hard with the hammer!), then I also supply these spare links seperately here. These links are high quality 'Renolds' make.

Magneto Chain Link and Half (Renolds)

Product no.: 0432 A11/113H

First and foremost i would say it is not recommended to fit a half link (or link and a half as it actually is), but I know that on some rare occasions you may have an unusual timing covers where the chain can either be too slack/tight with standard links. Therefore this item is for a Reynolds link and a half to fit Norton magneto chains
