[AT] OT, sort of: Harm in keeping clutch engaged while stopped?

[Mark Greer]

The thrust bearing surface on the crank will wear excessively if you ride
the clutch pedal for long periods of time or shift a lot. At one time in my
past I rebuilt a number of 366 and 427 Chevy tall deck truck motors, all of
which came out of delivery trucks. These were in C60 trucks that were used
primarily for in town deliveries with lots of shifting and sitting in
traffic. Almost every one had a crank worn well beyond acceptable limits on
the rear main thrust face. Over half of them required welding and regrind on
the thrust face and the rest were band-aided with special main bearings that
have an extra thick thrust flange.
