Cleaning, Inspection and Repair
Use the following procedures to clean, inspect, and repair the components of the
hoist system.
n
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.
Clean all hoist component parts in solvent (except for the brake friction discs). 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 scrape old Loctite® from the bushing bore. Dry each part using
low pressure, filtered compressed air. Clean the brake friction discs using a wire brush
or emery cloth. Do not wash the brake friction discs in liquid. If the brake friction
discs are oil soaked, they must be replaced.
n
Inspection
All disassembled parts should be inspected to determine their fitness for continued
use. Pay particular attention to the following:
1. Check mufflers for damage or excessive dirt.
2. Check side plates for cracks or bending, replace if one of these conditions is
found.
3. Inspect all gears for worn, cracked or broken teeth.
4. Inspect all bushings for wear, scoring or galling.
5. Inspect all bearings for play, distorted races, pitting and roller or ball wear or
damage. Inspect bearings for freedom of rotation. Replace bearings if rotation
is rough or bearings are excessively worn.
6. Inspect shafts for ridges caused by wear. If ridges caused by wear are apparent
on shafts, replace the shaft. Inspect all surfaces on which oil seal lips seat. These
surfaces must be very smooth to prevent damage to the seal lip.
7. Inspect all threaded items and replace those having damaged threads.
8. Inspect the brake drive plates and friction discs for oil. If the friction discs have
become oil-soaked, replace them. If the drive plates have become glazed, sand
them lightly using fine emery cloth and a flat surface as backing. Inspect the
remaining brake parts for warpage or other damage, and replace damaged parts
as necessary.
9. Measure the thickness of the brake friction disc. The brake friction disc must
show and even wear pattern. If the brake friction disc is 0.047 inches (1.2 mm)
or less, replace discs.
n
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.
Do not use steel wool.
1. Worn or damaged parts must be replaced. Refer to the Product Parts Information
manual 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 all nicks, burrs or galled spots on the 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 gaskets, oil seals and ‘O’ rings removed during hoist disassembly.

Assembly Instructions

Hoist Motor Assembly
Refer to Dwgs. MHP2999 and MHP3038.
1. Clean the grease from bearings (78) and install bearings (78) on drive gears (80),
(154) and idle gears (79) if replacement is necessary. Follow instructions 3 to 12
for bearing installation.
2. Clean interior and exterior diameter of bearings with Loctite® 7063 or equivalent.
NOTICE
• Refer to Dwg. MHP2644 on page 12 for instructions on Loctite placement,
follow these instructions for all bearings on each gear. Place Loctite®
“Activator” 7649 on all gear axles and holes in housing gears go through.
3. Put a continuous thin film of Loctite® 603 or equivalent on interior diameter of
bearings (78). Refer to Dwg. MHP2644 on page 12, A. Use a continuous thin
film of Loctite® 603 or equivalent to bond one bearing on each gear. Apply where
arrows indicate; B. Do not bond bearings on this side of gears; C. Use a
continuous thin film of Loctite® 603 or equivalent; D. Note: Wait 10 minutes with
the housing in this position, to ensure proper bond; E. Install brake hub and
rotate to ensure a proper bond; for correct application locations.
4. Put a continuous thin film of Loctite® 603 or equivalent on bearing diameters on
drive gears (80) and (154) then install bearings (78).
5. Install a second bearing (78), not bonded, on drive gears (80) and (154).
6. Put a continuous thin film of Loctite® 603 or equivalent on interior diameter of
bearings (78).
7. Put a continuous thin film of Loctite® 603 or equivalent on bearing diameters on
idle gears (79) and install bearings (78).
8. Install a second bearing (78), not bonded, on idle gears (79).
9. Put a continuous thin film of Loctite® 603 or equivalent in bearing bores in the
motor housing (76).
10. Install drive gear (80) and idle gear (79) into motor housing, ensure the drive
gear and idle gear are completely inside motor housing and leave the motor
housing in a position as shown on Dwg. MHP2644 on page 12 for 10 minutes.
11. Turn the gears with splined hub and a tool. Check bearings do not rotate on
bonded diameters and gears rotate freely.
12. Install exhaust pipes (60) with ‘O’ rings (45).
13. Lubricate and install ‘O’ rings (70) on motor housing (76).
14. Lubricate and install ‘O’ rings (71) in motor case (222).
15. Install motor cover (222) on motor housing (76).
16. Install and tighten screws (156). Install screw with Loctite® 243 or equivalent.
17. Install valve (86), valve (87) and spring assembly (221) in motor cover (83).

19. Put a continuous thin film of Loctite® 603 or equivalent in bearing bores in the
motor cover (222).
20. Install drive gear (154) and idle gear (79) into motor cover, ensure the drive gear
and idle gear are completely inside motor cover and leave the motor cover in a
position as shown on Dwg. MHP2644 on page 12 for 10 minutes.
21. Turn the gears with splined hub and a tool. Check bearings do not rotate on
