Valve Body

Disassembly

1. Remove and discard valve body gasket. Loosen and remove 11 bolts from reinforcement plates and detent spring guide bolt from the separator plate using a 10mm socket.

   NOTE: When removing the 11 bolts, note the location of the two shoulder bolts. They must be installed in the same locations when assembling the valve body.

   
   
   
   
   

2. Remove separator plate, reinforcement plates and separator plate gasket. Discard gasket.
   
   
   
   

3. Remove the two relief valves and seven check balls from the valve body. Note the location of the orange ball. It is not interchangeable with the six black balls.

   NOTE: The check balls are numbered one through eight. Check ball number seven was eliminated in a previous production year. There are a total of seven check balls.

   
   
   
   
   

4. The following procedural steps detail the removal and installation of the individual valves. Each valve body bore has been assigned a reference number on the assembled view. The illustrations have been assigned a corresponding reference number. Each set of illustrations contains the views necessary to remove and install the components contained in a particular valve body bore.
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   
   

Assembly

1. Install the seven body check balls.

   Note the location of the orange ball. This ball is larger than the others and must be positioned as shown.

   NOTE: The check balls are labeled one through eight. Check ball seven was eliminated in a previous production year. There are a total of seven check balls.

   
   
   
   
   

2. Install the pressure relief valves.
   
   
   
   

3. Note the location of the alignment holes. These two holes are smaller than the other bolt holes to ensure proper alignment of the gasket and separator plate with valve body. These two holes also align the valve body gasket and valve body assembly with the case.

    CAUTION: The two shoulder bolts must be installed at alignment holes only.

   
   
   
   
   

4. Use a new separator plate gasket. Slide the gasket and the separator plate over the two alignment holes. Position the three reinforcement plates and loosely install the 11 retaining bolts. Loosely install the detent spring guide bolt. (This bolt is the same as the short valve body assembly-to-case retaining bolts.)

    CAUTION: Do not use a shoulder bolt at the detent spring guide or damage to valve body casting will result.

   
   
   
   
   
   

   Item	Part Number	Description
   1	7F282	Reinforcement Plate
   2	7A008	Separator Plate
   3	—	Detent Spring Guide Bolt
   4	—	Alignment Hole

5. Starting at the center (large) reinforcement plate and working outward, tighten the 11 retaining bolts to 9-14 Nm (80-123 lb-in). Tighten the detent spring guide bolt to 9-11 Nm (80-97 lb-in). Install shoulder bolts.
