D4C &
D4D
STEERING CLUTCHES
| The D4C (models 39A, 40A) and D4D (78A, 22C, 82J, 83J
and others) steering clutches went through a small design difference from
the earlier D4 4G, 7J, 2T, 5T,
and 6U/7U series. The early D4's originally used the riveted on lining style of friction
discs and progressed to the bimetallic 3F5504 discs. The D4C and D4D
continued with the 3F5504 bimetallic discs while the steel discs
and inner driving drums went through a change. The inner driving
drums changed from straight splined driving hubs to a ramp style driving
drum (8H1174) and this requires the use of the 2H6936 steel
separator plates. This design began during the production of the
late 6U/7U models. D4 3F5504 Bimetallic friction discs @ $18.00 ea (Qty 11 used per clutch) D4 2H6936 Steel separator plates @ $12.00 ea (Qty 10 used per clutch) |
