3-10 Wire Rope Guide Band Replacement

{Code #24187, Pos. 9}

Though replacement is rare, it may be necessary

if damaged beyond repair. This procedure

requires that the drive sheave is removed.

1) Remove the oil drain plug as shown in Figure

336. Ensure that gearbox is lying with the oil

plug to the high side to prevent excessive oil

loss. This will allow air pressure to neutralize

in the gearbox.

2) Reinstall the oil plug. Do not apply too much

torque.

3) Turn the gearbox over so the driver disc

{Code #22357, Pos. 4} is face up. Use a

block of wood to level the gearbox. Remove

the wire rope guiding device (see Section 3-

6, step 6).

4) Carefully with two pry bars remove the

driver disc as shown in Figure 337.

5) Remove the damaged wear band. Inspect

and repair the casing base retaining lip as

needed. Place a light coat of grease on the

back of the new wear band.

6) Install the new wear band. Make sure the

band sits firmly into the casing base recess

as shown in Figure 338.

7) Using vise grips, twist the band into the

recess (Figure 339).

8) Reinstall the driver disc to the gearbox. There

will be resistance due to the air trapped

below the disc.

9) While holding the sheave in place, turn the

hoist over so that the oil plug is to the high

side again. Remove the oil plug same as

before.

NOTE

You will be removing the oil plug again.
