CLEAN
^
All valves, springs, bushings and control valve body in clean solvent.
^
Dry using compressed air.
INSPECT
^
All valves and bushings for:
-
Porosity
-
Scoring
-
Nicks
-
Scratches
^
Springs for damaged or distorted coils.
^
Valve body casting for:
-
Porosity
-
Cracks
-
Inter connected oil passages
-
Damaged machined surfaces
ASSEMBLE
^
Control valve assembly (350) exactly as shown.
-
Notice the position of the valve lands and bushing passages.
-
Position the pressure control solenoid so the connector tabs face outward.
NOTICE: TCC PWM solenoid (396) cannot be installed until TCC solenoid has been installed and torqued to proper specifications.
INSTALL OR CONNECT
1. Checkballs into the valve body assembly (350).
^
Retain with Transjell TM J 36850 or equivalent.
2. Valve body assembly (350).
^
