Grease fitting
Frequently Asked Questions
Q: What is a grease fitting and why is it important on forklift equipment?
A: A grease fitting (also called a zerk fitting) is a small threaded connector that allows pressurized grease to be injected into bearing assemblies and mechanical joints. On forklifts, grease fittings are installed on wheel bearings, pivot joints, and load wheel assemblies to reduce friction, dissipate heat, and prevent component wear. Regular greasing through these fittings extends equipment lifespan significantly.
Q: What forklift models and brands use this grease fitting?
A: This grease fitting (SKU 0013898CE) is used on forklifts from manufacturers including Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. The fitting is a standard component across many models. Verify the part number 0013898CE against your forklift documentation to confirm compatibility with your specific model and generation.
Q: How do I install or replace this grease fitting?
A: To replace a grease fitting: (1) Clean the area around the old fitting with a cloth to remove debris. (2) Using the appropriate wrench size (typically 1/2 inch or 9/16 inch), unscrew the old fitting by turning counterclockwise. (3) Clean the threaded hole to remove any old grease or rust. (4) Install the new fitting (0013898CE) by screwing it in clockwise until snug. Do not over-tighten, as this can strip the threads. (5) Wipe away excess grease after installation.
Q: What type and grade of grease should be used with this fitting?
A: Use a general-purpose lithium complex bearing grease that meets NLGI Grade 2 specification. This is the industry standard for material handling equipment. The grease should be compatible with both steel and elastomer seals on your forklift. Avoid thin greases (NLGI 0 or 1) as these will leak out quickly. Consult your forklift manual for the preferred grease brand, as some manufacturers specify proprietary formulations.
Q: How often should I grease this fitting during normal operation?
A: Grease load wheel and bearing fittings every 3 to 6 months under normal warehouse use, or every 100 to 200 operating hours. If operating in dusty or outdoor conditions, increase frequency to every 2 to 3 months. Always follow your forklift manufacturers maintenance schedule. Over-greasing can be as problematic as under-greasing, so use only the amount specified in the equipment manual (typically 2 to 4 pumps from a hand-held grease gun).
Q: What are signs that a grease fitting is clogged or damaged?
A: Signs of a failed fitting include: grease is impossible to pump in despite proper pressure application; grease leaks continuously around the fitting even when not greasing; the fitting is visibly cracked or bent; or the fitting spins in its bore without tightening. If the fitting cannot be cleaned or loosened, it must be replaced (SKU 0013898CE) to ensure the bearing assembly can receive proper lubrication.
