Grease fitting
Frequently Asked Questions
Q: What is a grease fitting and why is it important on forklifts?
A: A grease fitting (also called a zerk fitting) is a threaded nipple that allows pressurized grease to be injected into pivot joints, bearings, and suspension points. On forklifts, grease fittings enable scheduled lubrication to reduce wear, prevent corrosion, and extend component life.
Q: Which forklift components use grease fittings like part 220000964?
A: Grease fittings are found on mast pivot points, load wheel hubs, steer wheel hubs, steering pivot joints, and lift arm connection points. Part 220000964 is compatible with multiple forklift models. Verify the location and thread size on your equipment before ordering.
Q: What happens if grease fittings become stuck or corroded?
A: A stuck or corroded fitting prevents grease injection, causing downstream components to run dry. This accelerates bearing wear, increases steering effort, and creates safety hazards. Corroded fittings should be replaced with fresh units like part 220000964 to restore lubrication access.
Q: What material is part 220000964 made from?
A: Grease fittings are typically made from hardened steel with a zinc or nickel plating for corrosion resistance. The internal ball check valve prevents grease backflow and maintains system cleanliness.
Q: Are all grease fittings the same size and thread type?
A: No. Grease fittings come in different thread sizes (commonly 1/4-28 SAE and M8x1.0 metric) and styles (straight or 90-degree). Verify your forklift specification and the thread size of the replacement fitting. Using the wrong size will result in poor seal and grease leakage.
