Frequently Asked Questions
Q: What does the HW-1852 grease fitting do?
A: The HW-1852 is a grease fitting designed for lubrication points on electric lift truck components. It provides an access point for pressurized grease application, enabling scheduled maintenance without disassembling sealed bearings or joints. Grease fittings maintain proper lubrication under load and vibration.
Q: Is the HW-1852 grease fitting compatible with standard grease guns?
A: The HW-1852 uses a standard Zerk-type fitting design compatible with manual and power grease guns used in material handling maintenance. Verify the fitting thread size and type match your grease application equipment. Most portable grease guns used on Crown, Toyota, Raymond, Yale, Hyster, and similar brands work with standard Zerk fittings.
Q: How do I know if the HW-1852 grease fitting is damaged or leaking?
A: Replace the HW-1852 if grease is leaking from the fitting housing, the ball check valve is stuck or broken, or if the fitting cannot hold grease pressure when applied. Damaged fittings allow contaminants to enter bearing cavities and cause premature wear. Inspect fittings regularly during scheduled maintenance intervals.
Q: Which electric lift truck models use the HW-1852 grease fitting?
A: The HW-1852 is used on multiple electric lift truck models from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT. Verify the exact lubrication point location in your equipment manual before ordering. Fitting placement varies by mast design and load wheel assembly.
Q: What grease type should be used with the HW-1852?
A: Use NLGI Grade 2 multi-purpose lithium or calcium complex grease for the HW-1852 fitting. Consult your equipment maintenance manual for specific grease specifications. Do not use light machine oil or non-rated greases, as they may not provide adequate load-carrying capacity in bearing applications.
