DISASSEMBLY (continued)
NOTE
The joint between the elbow and the flange base is supported by ball bearings. These
ball bearings will fall out and are easily lost during Disassembly. In order to prevent the
loss of ball bearings, place several wiping rags under the joint during Disassembly.
8.
Position several wiping rags under the joint between the elbow (7) and the fire monitor flange base (2). Turn the fire
monitor flange base and elbow to permit the ball bearings (14) to fall from the swivel plug (13) holes. It may be necessary
to insert a length of flexible wire into the swivel plug holes to coax the ball bearings out.
9.
Count and record the number of ball bearings (14) that were removed from the joint. There are normally 45 ball bearings
in each of the two rows (total of 90), but this number can vary.
10. Use a twisting, pulling motion to separate the elbow (7) from the fire monitor flange base (2). If the components do not
come apart easily, repeat step 8 to ensure that all of the ball bearings (14) have been removed from the joint.
11. Remove the zerk fittings (15), O-rings (16 and 17), and brake band (18).
12. Remove the handle (19), grip (20), and stop stud (21) only if they will be replaced or if the outlet elbow (6) will be replaced.
13. Remove the gasket (22). Retain the gasket for use as a pattern in step 1 of Installation.
CLEANING
WARNING
Cleaning solvent is flammable and its vapor is potentially explosive. Do not use clean-
ing solvent in the vicinity of spark, open flame, or excessive heat. Do not use cleaning
solvent in unventilated spaces. Failure to comply can result in serious injury or death.
Do not allow hydraulic fluid or cleaning solvent to come in contact with unprotected
skin or eyes. Prolonged skin contact can cause illness or injury. Eye contact can cause
serious injury. Always wear chemical protective gloves and goggles when handling
used hydraulic fluid and cleaning solvent. Failure to comply can result in illness, seri-
ous injury, or death.
1.
Don chemical protective gloves and goggles.
2.
Clean the ball bearings (8, 9, and 14), the zerk fittings (15), the outlet elbow (6), the elbow (7), the fire monitor flange base
(2), and any other grease contaminated parts with cleaning solvent.
3.
Wipe all cleaned parts dry with clean wiping rags.
4.
Inspect all parts for cracking, wear, or other damage.
