Cambox Bearing - SOHC (Inter Mod 3040 and CS1CJ) Camshaft Back Roller Bearing : RHP C3

- Single row caged roller bearing. Fitted to Model 30/40 (International) SOHC engines. These are either RHP or Hoffman (Hoffman became RHP) - both best quality and in correct and very difficult to find C3 fit.

(C3 type are slightly looser tolerance bearings and were originally used in these racing engines. The C3 type are not essential for cambox's - but are definitely a rare luxury today, when even the standard RHP type have been unavailable for the last couple of years). Not cheap - but the proper thing and when they are gone they are gone!!

Note this bearing, fitted to International Nortons is bigger than the bearing fitted to SOHC magnesium cambox backplates. This bearing is 1.812" outer diameter - to fit SOHC aluminium cambox's, in case you are not sure which bearing you require.
