DISTRIBUTOR CAP 18D2 REPO
Reproduction distributor cap for the Lucas 18D2 distributor, also listed as 48-98660.
This is a reproduction distributor cap for the Lucas 18D2 distributor, listed in our records under part number 425049 and also known by the older number 48-98660. If your bike's parts book still shows the earlier form, that's the same cap.

The 18D2 distributor was fitted to a range of Triumph and BSA machines running that ignition setup, and the cap is the part that seals over the distributor body, carrying the rotor arm contact and the connections that feed the plug leads down to the points and condenser underneath. It's a wear-and-tear item — cracks, carbon tracking, or a loose fit on the body are the usual reasons to swap one in.
We don't have a lot of extra detail on file beyond the description, so if you're not sure your distributor is an 18D2, give us a call or check the casting number before ordering.
