Mini Spares special baulk rings are CNC grooved and precision machined for concentricity. They use the original type fixings to ensure that the correct areas receive heat treatment. They are similar to the pre 2000 Genuine Rover product in terms of performance and reliability and are better and cheaper than the later Rover product which proved to be unreliable in service.
This type of baulk (synchro) ring has been the same since 1962 except for changing from steel to sintered. The rings slow down the gears to ensure that they mesh without crashing. They have a friction surface that is the first thing to engage with the next gear when shifting. The height that the ring sits proud of the cone surface indicates the wear, but the common sense approach is to replace them sooner rather than later.
Order as 22G2033EVO. Retail price £15.66 inc VAT each. Four are required per car.
NB: These are the Mini Spares version of the genuine Rover sintered type but for a metal upgrade based on the original type used on 1960’s Coopers, Mini Spares can supply part number C-22A1741.
