Frequently Asked Questions
Q: What is the SKU 973499 grease fitting and what equipment does it fit?
A: The 973499 is a grease fitting (also called a grease nipple or zerk) designed for electric lift trucks including Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and similar models. It is installed on axles, load wheels, and mast pivot points to allow periodic lubrication of bearings and moving components. The 973499 is a direct OEM replacement fitting.
Q: What are the thread size and material specifications for the 973499 grease fitting?
A: The 973499 grease fitting has a standard metric thread size, typically M8 x 1.25 or M10 x 1.0, with a hexagonal head design for standard grease gun attachment. The body is constructed from chrome-plated steel or zinc-plated carbon steel to resist corrosion in warehouse and outdoor environments. For exact thread specification and head size, confirm your equipment model with us.
Q: How often should grease be applied through the 973499 fitting?
A: Grease application frequency through the 973499 fitting depends on equipment duty cycle and environment. Typical intervals are quarterly for standard warehouse use, or monthly for high-intensity operations or outdoor use. Apply 2 to 4 pumps of general-purpose NLGI Grade 2 bearing grease per fitting each cycle. Increase frequency in wet, cold storage, or heavily loaded applications.
Q: What type of grease should be used with the 973499 fitting?
A: The 973499 fitting is compatible with standard NLGI Grade 2 multipurpose mineral-based bearing grease rated for general industrial use. In cold storage (below 0 degrees Celsius), use low-temperature grease formulated for cold environments. Avoid lithium complex or food-grade greases unless your equipment manufacturer specifies them. Always use grease compatible with the bearing seals to prevent seal degradation.
Q: Can the 973499 grease fitting be replaced if it becomes damaged or clogged?
A: Yes, the 973499 is a replaceable grease fitting. If the fitting threads strip, the spring valve becomes stuck, or the sealing surface corrodes, the fitting can be unscrewed and replaced with a new 973499 unit. Always verify that the thread size and head type match the equipment mounting hole. Use thread sealant or a new fitting with an O-ring seal to prevent grease leakage after replacement.
