7. Do not remove the needle roller bearings (63A) or (58)
from the planet frame or planet gears unless required for
repair. If removed they must be discarded and replaced with
new sets.
8. Drive out the throttle lever retaining pin (36) from the
throttle shaft (32).
9. From the motor end of the hoist, withdraw the throttle shaft
(32) and remove the throttle lever (35), throttle lever thrust
washers (36A) and throttle shaft spring (37).
10. Withdraw the ring gear (52), powered chain wheel (51A),
ring gear bearing (50) and planet frame bearing (63C).
11. Remove the four chain guide capscrews (4A), lockwashers
(4B) and the chain guide (4).
12. Remove the chain guard (5).
Chain Container
Fabric Chain Container Disassembly
Refer to Dwg. TPC451-3
1.
Run bottom block to lowest point to remove chain from
container. Disconnect hoist from air supply.
WARNING
• Disconnect the hoist from the air supply before removing
chain container.
1. Separate connecting link (91) and remove support chain
(306).
2. Remove nuts (303), lockwashers (304) and bracket bolts
(302) connecting mounting bracket (301) to hoist.
3. Remove container as an assembly from hoist.
4. If further disassembly is required, refer to Dwg. TPC451-3
to separate the assembly into its component parts.
Metal Chain Container HLK-K750 Disassembly
Refer to Dwg. MHP1029
1.
Run bottom block to lowest point to remove chain from
container. Disconnect hoist from air supply.
WARNING
• Disconnect the hoist from the air supply before removing
chain container.
2. Remove bracket (317) from chain container by removing
bolts (322), lockwashers (316) and nuts (303).
3. Remove chain container from hoist by removing bolts
(324), lockwashers (325) and nuts (326).
4. To separate the bracket (317) from end link of load chain,
drive out pin (34).
5. To remove stop ring (319), remove setscrew (321) and pin
(320) from stop ring. Slide stop ring off of chain.
Cleaning, Inspection and Repair
Use the following procedures to clean, inspect, and repair the
components of the hoist.
Cleaning
CAUTION
• Bearings that are loose, worn or rotate in the housing must
be replaced. Failure to observe this precaution will result in
additional component damage.
• Do not use trichloroethylene to clean parts.
Clean all hoist component parts in solvent (except for the brake
discs). Care must be taken to clean components thoroughly, but
not damage components during cleaning. The use of a stiff
bristle brush will facilitate the removal of accumulated dirt and
sediments on the gears and frames. If bushings have been
removed it may be necessary to carefully remove old Loctite
®
from the bearing bores without damaging the mating surfaces.
Dry each part using low pressure, filtered compressed air.
Inspection
All disassembled parts should be inspected to determine their
fitness for continued use. Pay particular attention to the
following:
1.
Inspect all gears for worn, cracked, or broken teeth.
2. Inspect all bushings for wear, scoring, or galling.
3. Inspect shafts for ridges caused by wear. If ridges caused
by wear are apparent on shafts, replace the shaft.
4. Inspect all threaded items and replace those having
damaged threads.
5. Measure the thickness of the brake discs (79). If the brake
discs are less than 0.090 in. (2.23 mm) replace the brake
discs (79) as a set.
6. Check mufflers (20) and (31) for damage or excessive dirt.
7. Check bearings for rotation and wear. Replace if bearings
do not rotate smoothly, without sticking or binding, or if
bearings are damaged or excessively worn.
8. Inspect brake driver bearing wear area on brake driver (73)
and in planet gear frame (54) for ridges or galling. If either
condition exists replace parts.
Repair
Actual repairs are limited to the removal of small burrs and
other minor surface imperfections from gears and shafts. Use a
fine stone or emery cloth for this work.
1.
Worn or damaged parts must be replaced. Refer to the
applicable parts listing for specific replacement parts
information.
2. Inspect all remaining parts for evidence of damage.
Replace or repair any part which is in questionable
condition. The cost of the part is often minor in comparison
with the cost of redoing the job.
3. Smooth out minor nicks, burrs, or galled spots on shafts,
bores, pins, or bushings.
4. Examine all gear teeth carefully, and remove nicks or
burrs.
5. Polish the edges of all shaft shoulders to remove small
nicks which may have been caused during handling.
6. Remove all nicks and burrs caused by lockwashers.
7. Replace all seals, ‘O’ rings and gaskets.
NOTICE
• When assemblies are separated into component parts
discard all exposed ‘O’ rings and gaskets and replace with
new during assembly.
Assembly
The following assembly instructions are for a complete assembly
of the hoist component modules. Conduct those assembly steps
necessary to reassemble the hoist from the point of which your
disassembly ended. For example: if the brake was removed as an
assembly to access the hoist gears, it is not necessary to
completely reassemble the brake to reinstall. Conduct only the
steps necessary to reattach the brake assembly to the hoist.
General Instructions
Refer to ‘General Maintenance Instructions’ and also:
1.
The HLK Hoist is constructed of various modules. The
following instructions will first describe how to assemble
the individual modules and finally, how to assemble a
complete hoist from the assembled modules.
