This section provides information about the following
orbital dispenser components:
• Orbital Dispenser
• Tube Bearing
• Tube Support Bearing
• Orbital Dispenser
Orbital Dispenser Disassembly
Disassemble the orbital dispenser as follows:
1. Shut off material supply to the orbital dispenser.
2. Relieve material pressure in the system.
3. To ensure that power is removed from the orbital
dispenser, perform the following steps:
a. At the control assembly, move the MAIN power
switch to the OFF position.
b. Disconnect the motor control cable from the
control assembly.
4. Disconnect the motor control cable from the orbital
dispenser.
5. Separate the orbital dispenser from the dispense
valve at the 3/4-16 swivel fitting. Carry the orbital
dispenser to a work bench to do the following proce-
dures.
6. Remove nozzle (15).
7. Remove the nozzle guard (80) and bellows seal
(140).
8. Remove four screws (7) and lockwashers (5). Sepa-
rate lower housing (150) from motor assembly (6).
9. Remove inlet cap (2) from upper housing (3), expos-
ing top end of tube assembly (13).
10. Reassemble nozzle (15) loosely onto tube assembly
(13). Press nozzle to force tube free of orbiter cou-
pler assembly (24).
11. Remove nozzle (15) from tube assembly (13) and
remove tube assembly from motor assembly (6) and
upper housing (3).
12. If not using coupler repair kit (246292, 246293,
289311, or 289312), remove o-ring (12) from tube
assembly (13) and save for later use.
13. Remove four screws (4) and lockwashers (5), and
clamp assembly (160). Separate motor assembly
(6) from the upper housing (3).
Refer to tool kit 241569 for a 3/32 in. Allen wrench
and 1/4 in. combination wrench to facilitate disas-
sembly and reassembly procedures.
Tool kit (241569) is required for replacement of the
tube support bearing.
Refer to the Parts information on pages 16-17 while
performing orbital dispenser disassembly and reas-
sembly procedures.
ELECTROCUTION HAZARD
Installing and servicing this equipment requires
access to parts which could cause an electric shock
or other serious injury. Have only qualified electri-
cians access the control assembly.
To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 9.
HOT MATERIAL AND EQUIPMENT HAZARD
To prevent personal injury, make sure the orbital dis-
penser has cooled to ambient temperature before
service is performed.
Swivel fitting (1) may remain assembled to inlet
cap.
Do not remove male pin cable connector from
motor (6).
