3. To inspect or replace the Charge Relief Valve,
use a 1 wrench to remove the hex plug and
the spring and poppet. Remove the shims
from the counter bore of the plug. Do not
alter these shims unless new parts are used,
in which case adjusting the valve setting, by
shimming, is necessary. To install, insert
poppet, spring, shims and plug. Be certain
shims are in place in plug. Torque to 30-60 ft.
lbs.
4. The removal of the Charge Check Valves
requires the use of a draglink socket. These
check valves are cartridges which are
threaded into the end cap.
Installation
5. The
Charge
Check
Valves
are
interchangeable with each other.
It is
suggested that they be replaced in pairs. Use
caution when installing these valves to
prevent damage to the O-ring on the cartridge
as it is inserted past the threads in the end
cap.
6. After assembly, be certain the check
valves are below the surface of the end
cap. Torque check valves to 30-40 ft. lbs.
7. When installing the Charge Pump, align the
new gasket so that the small relief valve port
is open. Be certain the port in the charge
pump and the end cap are aligned. Rotate
the charge pump shaft so its tang aligns
approximately with the slot in the end of the
main pump drive shaft. Hold the idler spacer
in place and install the charge pump onto the
end cap. Rotate the pump slightly until the
tang and slot on the shafts engage and the
pump is solidly on the end cap.
8. Insert the four (4) cap screws and torque to
10-11 ft. lbs.
NOTE:
When reinstalling the vacuum inlet hose on
the charge pump, do not tighten to more than
14 to 21 ft. lbs. torque.
