SHIFT PRESSURE VALVE REPAIR - CONTINUED
Exercise care to keep dust, dirt and other contaminants out of shift pressure valve assembly. Make sure
hands, clothing and tools are clean. Do not assemble these parts where wind may carry airborne particles.
Failure to follow this procedure could result in damage to equipment.
Install washer (42) and screw (43) in valve body (3).
Spools, slugs, pistons and springs must be installed in the same position, in the same bore from which they
were removed. Some springs are color coded to match the color coding on the valve body, to aid in proper
assembly. Failure to follow this procedure could result in damage to equipment.
Use clean lubricating oil to lubricate three spools (50) and slugs (49) and install.
Chill stop (44) to -60F (-51C) and position in valve body (3).
Use a brass punch to install dowel (45) in stop (44). Ends of dowel (45) must be below surfaces of valve body (3).
Always wear safety glasses when removing or installing parts restraining compressed springs. Remove
restraining parts slowly to relieve spring pressure. Injury may result if you do not follow this procedure.
Install spring (46).
Use clean lubricating oil to lubricate and install new preformed packing (48) and piston (47).
