Frequently Asked Questions
Q: What is SKU 177413?
A: SKU 177413 is an OEM grease fitting, commonly known as a zerk fitting, used on manual pallet jack steer axles and thrust bearing assemblies. It accepts standard pneumatic grease guns for lubrication.
Q: What thread size and specifications does this grease fitting have?
A: This fitting features a 1/4 inch minus 28 UNF (Unified Fine) thread specification. The case-hardened low-carbon steel construction is OEM-standard for manual pallet jack lubrication points.
Q: What is the equivalent part number for this zerk fitting?
A: This OEM part is equivalent to interchange part number RA939-353-043. Cross-reference this number if you need to verify compatibility with your equipment manufacturer.
Q: Which manual pallet jack brands use this grease fitting?
A: This fitting is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and other OEM manufacturers. Verify your model and serial range to confirm fitment.
Q: How often should this grease fitting be used for lubrication?
A: Manual pallet jack axles and thrust bearings require periodic greasing based on your equipment maintenance schedule, typically every 40 to 50 operating hours or per your OEM manual. Regular lubrication extends bearing life and reduces steering resistance.
Q: What happens if a zerk fitting becomes stripped or damaged?
A: If the fitting threads become stripped, grease cannot be applied effectively and the bearing will lack proper lubrication, leading to accelerated wear, binding, or steering failure. Replace the fitting to restore proper maintenance capability.
