- CP3457-9Release Fulcrum Dia ‘A’ = 50mm.






RELEASE MECHANISM.)As the spring rate and clamp load of the clutch in-creases so does the release bearing load required to release the clutch. The release bearing used should be a highquality steel caged radius contact ball bearing either 38mm, 45mm or 50mm (for Ø115mm, Ø127mm, Ø138mm and Ø140mm carbon / race clutches) or 54mm for (Ø184mm, Ø200mm and Ø215mm carbon / race clutches). The release mechanism should be arranged so that the bearing is free of the spring fi ngers when the clutch is fully engaged. The release travel should be limited by means of an external stop to avoid damage to the diaphragm spring. Suitable release bearings are available from AP Racing see details opposite and below.

IMPORTANT NOTE / INSTALLATION OF BEARINGS.To prevent internal damage to ball races when fi tting bearings onto release mechanism, use only the minimum force necessary on the surfaces marked ‘B’ only. The following bearing assemblies are fi lled with Kluber Asonic HQ72-102 grease, CP3457-1, -2, -6, -11, -16.
