ABSTRACT:
A transmission bearing cover for limiting wear of a rotatable braking mechanism in a vehicle powertrain having a clutch for releasably coupling an engine to a transmission input shaft includes an annular non-rotatable member disposable about the input shaft and having an annular projection engageable with a non-rotatable clutch release bearing assembly. When the rotatable braking mechanism is substantially worn and the clutch is sufficiently disengaged, the clutch release bearing assembly axially translates to a clutch-braking position and engages the projection rather than the worn braking mechanism to prevent substantial damage to the bearing cover or bearing assembly.
