COMPONENT REBUILD
Valve Body Assemblies
1. Disassemble the main valve body, the lower
valve body and the accumulator valve body
using Figure 173 as a guide.
2. Disassemble the valve bodies one at a time.
Lay each valve line-up out in order as you
remove them from the valve body casting.
3. Inspect each valve, valve spring, bore plug and
retainers for any wear and/or damage.
Caution: Refer to Pages 22 through 33 for
the differences in "PTO" valve bodies and
the NON-PTO valve bodies and spacer plate.
None of these parts will interchange, so if
replacement is necessary, use extra care in
the inspection process for replacement parts.
