disassembly
1. Remove the bypass plate (22) from the
center section.
2. Remove the plug seals (26) and discard.
Refer to figure 31, on page 35.
IMPORTANT:
Before removing the check
plugs, it is important to note their specific loca-
tion, i.e., check plug (24) needs to be reinstalled
in the same port it was removed from and the
same for check plug (25). After removing the
check plugs, inspect for debris or damage.
3. Remove the check plugs (24) and (25) and
inspect. Refer to Check Plugs & Seals, page
35.
— Charge Relief Kit —
4. Remove the pin, spring and ball that make
up the charge relief kit (202). Depressing
the charge spring with the (clean) flat side
of a slotted screw driver will allow the pin
to slide out. Use caution when relieving
spring force. Inspect the center section at
the charge seat for wear or damage.
NOTE:
The check ball should seat properly in
the check seat.
inspection
1. Inspect all components for unusual wear or
damage. Pay particular attention to the cen-
ter section’s threaded ports and passages;
there must be no lose particles or debris.
assembly
1. Install the charge relief kit (202). Beginning
with the ball, then the spring, followed by,
the cross pin.
2. Install the new check plugs (24) and (25) in
their proper ports.
3. Install the new plug seals (26).
4. Install the bypass plate (22). Applying a very
small film of grease on the bypass plate, will
help secure it in the center section.
Center section — non-Charge
NOTE:
For non-charge ZT-2800 units without
“charge relief,” a rubber plug (16) will be
present rather than connecting tubes (ref.
on page 27, Figure 21a). See diagram to
the right.
