5.Remove four screws attaching gear box cover to gear housing and remove gear box cover. Limit switch drive shaft will come along with the cover.
6.Inspect gears for broken or severely worn teeth and inspect all bearings. Replace as necessary. The overload slip clutch is factory calibrated and must not be disassembled or readjusted.
7.Reassemble in reverse order of disassembly making sure gasket is in place and in good condition. Coat gasket with Permatex® or other gasket cement. Extreme care should be taken to avoid damage to oil seals.
8.Check all wire terminals to be sure they are properly seated and in accordance with wiring diagram. Before placing hoist back into service, check brake adjustment and limit switch stops.
Failure to follow proper lockout/tagout procedures may present the danger of electrical shock.
TO AVOID INJURY:
Disconnect power and lockout/tagout disconnecting means before removing cover or servicing this equipment.
Suspension
Use Replacement Parts List for Basic Hoist and Chaining Parts to help in repairs in this section (See Figures 12 and 20). The hoist sections must be separated at the top hook line in order to inspect the load sheave and chain guides. See CHAIN REPLACEMENT WITH NO CHAIN IN HOIST, page 8.
While this section is apart, check the following:
•Load sheave
•Chain guides and plates
•Chain
•Chain support (on 2 ton models)
•Bearings
Replace parts as necessary including screws, lockwashers, etc.
When reassembled, recheck limit switch operation. See LIMIT SWITCH ADJUSTMENT, page 8.
POWER CORD PRECAUTIONS WITH 1-PHASE HOISTS
Electric hoists require a sufficient power supply. It is especially important with
Such problems can be minimized by using 230V power on 115/230V hoists. The following are recommendations for the conductor gage size depending on the length, horsepower, and voltage.
