MAINTENANCE AND SERVICE

For safe and consistent operation of TWG hoists, gearboxes, and winches, a regular program of

preventive maintenance is strongly recommended. Regular oil changes with the correct oil and

frequency for the application and an annual inspection of the wear components will help ensure

a long life for your planetary geared products.

Maintenance Scheduling

Manufacturer recommends changing oil after first 50 hours of operation. All gearboxes require

the proper EP gear oil for lubrication. Some units may be equipped with a grease fitting for

lubrication of the output shaft bearings (pinion up applications). The shaft bearings should be

greased sparingly at every 50 operating hours with an EP lithium or GP bearing lube. For pinion

down applications, gearbox oil will lubricate shaft bearings

Oil Level Maintenance

Tulsa Winch recommends that the oil be checked and adjusted as part of the pre-use

inspection. If the oil level drops frequently or oil leakage is detected during an inspection,

maintenance should be performed to correct any problems.

Oil Change Interval

The oil in the gearbox and brake sections (if applicable) should be changed every 1000 hrs or

6 months of usage.
