Hilliard Clutch Maintenance
Large Truck Unit Centrifugal
Clutch Change (P/N 107-291)
Beginning in the second quarter of 2000 most
large truck units are equipped with centrifugal
clutch P/N 107-291, which supersedes P/N
107-204. Centrifugal clutch P/N 107-291 has
three belt grooves and its engagement speed is
600 ± 100 RPM. When this clutch is installed on a
unit equipped with a two groove belt, the belt
should be placed in the two grooves nearest to the
clutch hub.
