14. Install ring gear (18) on spline. Install spring washer (19)
with concave side toward ring gear. Install bearing (44) and
tap into place.
15. Install assembled parts in gear housing aligning the gear
teeth with the ring gear. Position the puller holes at the top
and bottom just off vertical. This may aid disassembly on
another occasion.
16. Lubricate 'O' rings (30) and (33) and install on brake cover
(35) and brake piston (29).
17. Install brake piston (29). Refer to "Brake Assembly" for
information on assembling remaining brake parts.
LCA060S and LCA120D Hoists
Refer to Dwg. MHP1465.
1.
Install 'O' rings (46) in gear housing (30). Ensure three
dowel pins (42) are in place in the gear housing (30) and
are undamaged.
2.
Install friction and steel discs. Beginning with a friction
disc (43) and then alternate with a steel disc (44) until discs
are used. Locate friction disc tabs in slots provided in gear
housing.
3.
Install bearing (5) in ring gear support (45) and secure with
retainer ring (40).
4.
Carefully install ring gear support in gear housing making
sure dowel pins are aligned with the holes in the ring gear
support. Tap down and secure with three capscrews (27).
Use Loctite
®
243 on capscrew threads.
5.
Install retainer ring (26) in ring gear (47) then install ring
gear in gear housing.
6.
Install two bearings (21) with a spacer (20) between, in
each planet gear (22).
7.
Install planet gears with bearings into planetary support
(48) and locate with planet axle (49). Place one bearing (24)
and one thrust ring (23) on each side of the planet gears.
Bearings (24) must contact inside face of planetary support
and thrust rings (23) must contact planet gears. Ensure
planet gears (22) are installed with the smaller gear head
diameter nearest the side of the planetary support (48) with
the puller holes.
8.
Align pin hole in planet axle with pin hole in planetary
support. Install pins (25). Tap down until flush with
planetary support.
9.
Time gears as shown in drawing MHP1417. Using a
separate ring gear tool to maintain gear position during
installation of planetary assembly is helpful. Tap down
until planetary assembly is fully seated.
(Dwg. MHP1417)
10. Install retainer ring (15) in ring gear (16). Install ring gear
in gear housing (30).
11. Install sun gear (41) and tap into position through bearing
(5) until seated.
12. Turn gear housing over and support to avoid damaging the
sun gear. Align tabs on steel discs (44) and install brake
sleeve (39) on sun gear spline. Secure in position with
retainer ring (36).
13. Install remaining brake parts as described in "Brake
Assembly."
14. Install oil seal (53) and 'O' rings (9) and (14) on gear cover
(13). Seal lip must be toward gear side.
15. Install ring gear support (54).
16. Install gear cover (13) in gear housing (30).
Pendant Assembly
Refer to Dwg. MHP1558 or MHP1544.
1.
Install 'O' rings (505 and 511) and protector (506) on valves
(509). Install valve assemblies in handle (514).
2.
Install levers (503) in pendant handle (514) with pin (502).
Stake pin in pendant handle at both ends to secure.
3.
Install screws (504) in levers.
4.
Install screws (515) in handle.
5.
Install balls (516) and springs (517) in handle (514). Secure
in position with plugs (518).
6.
On pendants with emergency stop, install emergency stop
button (508).
7.
Install exhaust washer (513) and secure in handle with
retainer ring (512).
8.
Adjustment:
a.
Connect the inlet of the pendant to 100 psi (7 bar) air
supply.
b.
Connect a manometer at the outlet of the lever to be
adjusted.
c.
Apply a small amount of Loctite® 243 on the
adjustment screw (504).
d.
Tighten the adjustment setscrew to obtain a pressure of
15 psi (1 bar) without actioning the lever.
e.
Release the adjustment setscrew by a half turn
(pressure must fall to zero).
f.
Push the lever. Check that pressure reaches 93 +/-7 psi
(6.5 +/- 0.5 bar). Check that there is no leak at the
exhaust.
g.
Release the lever, exhaust must occur and result in
rapid pressure reduction.
h.
Repeat operations f and g two or three times.
i.
Disconnect the manometer. Check to ensure that there
are no leaks when the lever is not activated.
j.
Repeat the operations from 8b. to 8i. with each lever.
Load Test
Prior to initial use, all new, extensively repaired or altered hoists
shall be load tested by or under the direction of a person trained
in safety and operation of this hoist. Dynamically load test hoist
to 100% of its rated capacity in accordance with ASME B30.16
standards. Testing to more than 100% is required to set overload
device and may be necessary to comply with standards and
regulations set forth in areas outside the USA.
