Elliott E190, Operation And Maintenance Manual

Page: 276 / 358

1
This manual will primarily assist in disassembly and assembly procedures of major components
for all 52 & 60 series Swing Drives. Item numbers, indicated in parentheses throughout this
manual, refer to the Tulsa Winch Model 52 and 60 series exploded assembly drawing located in
the back of this manual.
LUBRICATION AND MAINTENANCE
Manufacturer recommends changing oil after first 50 hours of operation. Oil should be changed
at 500-hour intervals thereafter. All gearboxes require GL-5 grade EP 80/90 gear oil for
lubrication. Some units may be equipped with a grease fitting for lubrication of the output shaft
bearings (pinion up applications). The shaft bearings should be greased sparingly at every 50
operating hours with a lithium or GP bearing lube. In pinion down applications, gearbox oil will
lubricate Shaft bearings.
OIL CAPACITIES:
52 60
Pinion up: 70 Ounces 128 Ounces
Pinion down: 88 Ounces 100 Ounces
DISASSEMBLY PROCEDURE
FOR 52 & 60 SERIES SWING DRIVES
1. Remove drive from vehicle and drain
gearbox lubricant by removing the drain
plug (
31 ).
2. Remove the motor from the motor
adapter ( 30 ).
3. Remove the brake assembly from the
gear housing assembly ( 7 ) by removing
eight hexhead capscrews ( 18 ). NOTE:
Notice the position of the brake port in
conjunction with the drain and fill holes
in the housing for reassembly.
4. Inspect the brake housing o-ring (
14 ) for
damage. Replace if necessary.
5. Separate the motor adapter (
30 ) from
the brake housing ( 15 ) by removing
eight capscrews ( 32 ). NOTE: Notice
the position of the motor mounting hole
in relation to the brake release port for
re-assembly. CAUTION: The motor
adapter is spring-loaded and the
capscrews should be loosened in a
sequence that will allow an even load
distribution on the motor adapter.
6. Inspect the motor adapter o-ring (
29 ) for
damage. Replace if necessary.
7. Remove the six springs (
33 ), piston ( 25 ),
and brake driver ( 27 ) from brake
housing ( 15 ). NOTE: On 52 series
swingdrives notice the position of the
dowel-pin hole in piston with respect to
the brake release port for re-assembly.
NOTE: A port-a-power can be used to
assist in the removal of piston by slowly
pressurizing the brake release port until
piston clears the top of housing
(
15 ).Remove stator plates ( 19 ) and
friction discs ( 20 ) from the brake
housing ( 15 ). Inspect stator plates for
excessive grooving or burn spots. Also,
inspect friction discs for wear. Replace
as required.
(Ref. Fig. 1)
8. Inspect the piston o-rings ( 22 & 23 ) and
the back-up rings ( 21 & 24 ) for damage,
replace if necessary. (Ref. Fig. 2)
9. If applicable remove 2
nd
piston ( 36 ) from
the brake housing ( 15 ), inspect o-rings
