1 C DISASSEMBLY (AUXILIARY PARTS)
DISASSEMBLY
1. Remove in the sequence shown in the figure referring to the disassembly note for specially marked
parts.
2. Code all identical parts (such as pistons, piston rings, connecting rods, and valve springs) so that
they can be reinstalled in the cylinder from which they were removed.
3. Clean the parts with steam, blow off any remaining water with compressed air.
Note
Care should be taken during the disassembly of any part or system to study its order of
assembly. Any deformation, wear, or damage should also be noted.

HYDRAULIC CIRCUIT 7C
HYDRAULIC CIRCUIT
OUTLINE
The flow of the individual hydraulic circuits are identified as listed below.
(Numbers indicate individual circuits)
Line pressure source 7
Control element operation system line pressure.... 1,2,3,4,5,6,7,8,9,10,11,12
Auxiliary line pressure 13
Throttle system pressure 16,17,18,19
Governor system pressure 15
Torque converter system pressure 14
1. Line pressure
The line pressure is the hydraulic pressure of the oil emitted from the oil pump after adjustment
by the pressure regulator valve.
2. Throttle pressure
Derived from the line pressure, the throttle pressure is the hydraulic pressure generated by the throttle
valve which operates in conjunction with the intake manifold vacuum.
3. Governor pressure
Also derived from the line pressure, the governor pressure is the hydraulic pressure which varies
in conjuction with the vehicle's speed. It is controlled by the governor rotating together with the out-
put shaft.
