Cleaning, Inspection and Repair

Use the following procedures to clean and inspect the components of hoist.

Cleaning

Clean all hoist component parts in solvent (except for brake disks). Use of a stiff bristle brush will facilitate removal of accumulated dirt and sediments on gears, shafts and housings. Dry each part using low pressure, filtered compressed air. If brake disks are oil-soaked, they must be replaced.

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 shafts for ridges caused by wear. If ridges caused by wear are apparent on shafts, replace shaft.

3.Inspect all threaded items and replace those having damaged threads.

4.Inspect brake disks for oil. If brake disks are oil-soaked, replace brake disks.

5.Measure thickness of brake disks. New brake disk thickness is 3 mm. Discard brake disks if thickness is 2 mm or less.

Repair

Actual repairs are limited to removal of small burrs and other minor surface imperfections. Use a fine stone or emery cloth for this work.

1.Worn or damaged parts must be replaced. Refer to 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 all minor nicks, burrs, or galled spots on shafts, bores, pins or spacers.

4.Polish edges of all shaft shoulders to remove small nicks which may have been caused during handling.

5.Remove all nicks and burrs caused by lockwashers.

Hoist Assembly

Refer to Dwg. MHP0773 on page 12.

Load Sheave Assembly

1.Install side plate threaded spacers (94) in side plate assembly A (gear side) (5).

2.Install load sheave (7) in side plate assembly A (5).

3.Apply grease to Bearing A (91) located on end of load sheave (7).

4.Install chain leaders (9) and (11), stripper (10), guide ring B

(8) and top hook (45) on top pin (48) in side plate assembly A (5).

5.Carefully install side plate assembly B (brake end) (12) to engage locating diameters of parts installed in step 4.

6.Push side plates together to ensure all parts are located and secure.

Gear End Assembly

Follow steps 1 through 6 described in ‘Load Sheave Assembly’.

1.Install splined gear (4) on load sheave (7). Install snap ring

(62)on load sheave (7) to secure splined gear (4).

2.Install drive shaft (3) through center of load sheave (7).

3.Install driver shaft gears (2) so gear teeth are correctly timed and spigots locate in bearing sleeves in side plate assembly A (5). Refer to ‘Gear Timing’ section.

4.Apply a thick coat of grease as recommended in “LUBRICATION” section to all gear teeth. Install gear case

(1)over driver shaft (2) to locate and engage gear spigots.

5.Secure gear cover with prevailing torque type nut (60).
