COMPONENT SYSTEM DESCRIPTIONS
A. BASKET (TUMBLER) DRIVE SYSTEM
There are two (2) drive assemblies. Each drive assembly consists of a 5 HP (3.72 kw) drive motor, which is
connected to the drive shaft by two (2) “B” section V-belts, driving a shaft-mounted (5.6 to 1 ratio) gear reducer.
This produces a basket (tumbler) speed of approximately 31.5 r.p.m. Proper tension is maintained on the
V-belts by tightening the gear reducer turnbuckle support. The oil in the gear reducer must be changed every
6 months by 1-1/2 quarts (1.4 liters) of I.S.O. viscosity grade 460 gear oil.
