Surplus and new spares are made available to site members and up to date technical, machine dating and component drawing information is available to download, most of which is not available elsewhere.

Technical help from Rudge experts...

Sam E Radial is on hand to answer those nagging technical questions like "I am restoring a 1928 Special cylinder head which came to me dismantled. I have 2 spacers on the rocker spindles, can you tell me where they go?

The 1928 Special/Sports was the first road cylinder head to have splayed ports to aid cooling. The spacers, Overhead Rocker distance collar L318 x 25, are fitted on the non pushrod (LH) side and control the lateral movement of the rockers. (see picture below) These can be re-made, if the rocker lateral movement exceeds approx 0.010".
