ASSEMBLY
CAUTION
As the safety relief valve and check valves are assembled, the arrangement of
preformed packings and backup rings is extremely important. If the preformed
packing and backup rings are improperly installed, internal leakage or premature
equipment failure may result. Use the illustration shown for proper arrangement of
parts.
1.
Apply petroleum jelly to preformed packings (21 and 18) and backup rings (22, 20, and 19).
2.
Install backup ring (22), two preformed packings (21), backup rings (20 and 19), and preformed packing (18) onto
CKCB XCN check valve (17).
3.
Repeat steps 1 and 2 as required for all CKCB XCN check valves (17) disassembled.
4.
Remove caps/plugs installed into steering control manifold (2) and install four CKCB XCN check valves (17) as
required into steering control manifold (2).
5.
Apply petroleum jelly to preformed packings (16 and 14) and backup rings (15 and 13).
6.
Install preformed packing (16), backup ring (15), preformed packing (14), and backup ring (13) onto check valve
(12).
7.
Repeat steps 5 and 6 as required for all check valves (12) disassembled.
8.
Remove caps/plugs installed into steering control manifold (2) and install eight check valves (12) as required into
steering control manifold (2).
9.
Apply petroleum jelly to preformed packings (11 and 8) and backup rings (10 and 9).
10.
Install preformed packing (11), backup ring (10), backup ring (9), and preformed packing (8) onto RPEC LCN
safety relief valve (7).
11.
Remove caps/plugs installed into steering control manifold (2) and install RPEC LCN safety relief valve (7) into
steering control manifold (2).
12.
Apply petroleum jelly to preformed packings (6 and 4) and backup rings (5 and 3).
13.
Install preformed packing (6), backup ring (5), preformed packing (4), and backup ring (3) onto CXDA XAN check
valve (1).
