16 wire ropes will eventua lly deteriorate to a point where they are not safe and will require replacem ent. Wire rope should be thoroughly inspected at regular mo nthly intervals by an authorized person an d a determination made whe n further use of the rope would constitute a safety hazard.
17 CAUTION It is imperative that rope reel or coil rotates as rope un winds. If coil or reel does not rotate the wire will be twisted as it is uncoiled and kinking will result. A kinked rope may be damag ed and unsafe for maximum service. b) Before removing the old rope, refer to reeving diagram, Figure 5- 6.
18 torque the remaining tw o (2) rope clamps in sequence to 50 ft-lb s. (2) With all personnel clear of hoist – TURN ON POWER.

19 spur. Th e gear shafts are supp orted with ball bearings housed in the back of the case and in the cover. The inp ut helical pinion is cut directly into the motor shaft. An oil seal housed in the gear case at the motor input seals the motor shaft a s it passes into the gear case.
20 (4) Disconne ct the wiring and co nduit from the motor junction box. (5) Provide a means to support the hoi st motor. The hoist motor weig hs approx- imately 250 lbs. And must be held lev el while removing and installing. (6) Once the motor is properly supported, remove the hardware fastening it to the gear case.
21 (2) Make sure power to the hoist is off and locked out. (3) Remove the four (4 ) bolts attaching the fan shroud to the motor and remove the fan shroud. See Figure 5-9. (4) Carefully roll the large O-rin g from the groove over the air gap back toward the magnet body.
22 (3) Connect the brake leads to the terminal block on the brake body. (4) Install the forward fan mounting retaining ring and inst all the fan. Install the rear retaining ring. Install the f an shroud and bolts. (5) Test hoist per Section V, Paragraph 5-13.
23 b) Procedure. Remove load from the hook. To disconnect the geare d limit switch refer to Figure 7-2. Remove the limit switch cover then loosen the two (2) scre ws holding the locking plate in place. Allow the lo cking plate to slide down and di sengage from the adjustment discs.
24 SECTION VI – TROUBLE SHOOTING 6-1. GENERAL. This section c ontains possible causes and solutions to common hoist problem s. Please attempt to remedy your hoist problems by following these steps before contacting t he factory.
25 SECTION VI – TROUBLE SHOOTING TROUBLE PROBABLE CAUSE REMEDY 6-4 Hook Will Lower, But Not Raise. a. Excessive load. b. Hoist electrical circuit open. c. Contactor assembly not functioning. d. Up, down button inoperativ e. a. Reduce loading to rated load of hoist as shown on nameplate.
26 This limit switch has a rota ry screw d riven by a gear reduction that is coupl ed to the end of the drum shaft. Adjustment discs operate the contacts of separate switches, one for the hoisting circuit and one for the lowerin g circuit.
