These specials are CNC grooved for correct shape and machined for concentricity using the original type fixings to get the correct areas of heat treatment plus correct degrees of angles on specific areas. Manufactured from the original drawings, giving them the same quality and reliability in performance as the Rover Baulk Ring supplied pre millennium.
This type of remote baulk (synchro) ring has been the same since 1962 but previously changed from steel on Cooper s to the current sintered type.
These rings slow down the gears to ensure that they mesh without crashing. They have a friction surface on them that is the first thing to engage the next gear when shifting. The height of how the ring sits proud of the cone surface indicates the wear, but the common sense approach is to replace them.
Sold individually.
