1. Refer to the appropriate illustration 195, 196
or 197. Thoroughly clean all of the previously
removed components. Inspect all of the
components for wear and for damage. Especially
check the condition of the hose for the connector
(9) and the diaphragm or the seal ring (4) for
damage. Replace any component that is worn
and/or damaged.
2. If the valve mechanism cover (5) was removed,
install the valve mechanism cover. Refer to
this Disassembly and Assembly Manual, "Valve
Mechanism Cover - Remove and Install".
3. If equipped, install the seal ring (4) in the recess
(11) in the valve mechanism cover (5).
Improper assembly of parts that are spring loaded
can cause bodily injury.
To prevent possible injury, follow the established
assembly procedure and wear protective equip-
ment.
4. If equipped, install the spring (12), the cap (13),
and the diaphragm (4) into the recess (11) in the
valve mechanism cover (5).
5. If equipped, ensure that the two domes on the
plate (3) are uppermost and ensure that the offset
hole is toward the connector (9) of the valve
mechanism cover (5). Install the plate (3). Install
the screws (2). Tighten the screws (2) to a torque
of 1.3 N·m (11.5 lb in).
6. Push the plastic cover (1) onto the valve
mechanism cover (5).
7. Install a new O-ring (10) onto the connector (9).
8. Install a new joint (8) to the connector (9). Install
the connector (9) into the valve mechanism cover
(5) and onto the cylinder head.
9. Install the fasteners (6). Tighten the fasteners (6)
to a torque of 9 N·m (80 lb in).
10. Install the hose onto the connector (9). Ensure
that the hose is clear of all hot surfaces, clear
of all components that move, and clear of all
g01122836
components that vibrate when the engine is
operating. Tighten the hose clamp (7) to a torque
of 5 N·m (44 lb in).
