Ref Description
1 1152-420-000A CLUTCH SHAFT
Following initial testing and racing of the 1152-900-000A gearbox in the LMP3
application, it has been determined that the diameter of the ground nose journal on the
1152-420-000A Clutch Shaft requires amendment to optimise the fit inside the engine
crank bush.
Clutch shafts with issue number 3 or lower were manufactured with the ground nose
journal diameter measuring Ø15.938/15.927mm. These parts require modification to
reduce the diameter to Ø15.799/15.773mm (ref. Figure 1.1).
