Frequently Asked Questions
Q: What is a zerk and what does the TO 00591-36910-81 zerk do?
A: A zerk, also called a grease fitting or grease nipple, is a component that allows lubrication of pivot points, bearings, and joints in material handling equipment. The TO 00591-36910-81 zerk is a Toyota OEM grease fitting for electric lift truck suspension and steering components.
Q: Where is the TO 00591-36910-81 zerk located on an electric lift truck?
A: Zerks are typically located at steering linkage joints, suspension pivot points, and load wheel assemblies. The exact location of TO 00591-36910-81 depends on your specific Toyota lift truck model. Consult your equipment manual for zerk locations and lubrication intervals.
Q: How often should the TO 00591-36910-81 zerk be lubricated?
A: Zerk lubrication intervals vary by model and usage frequency. Most electric lift trucks require greasing every 50 to 100 operating hours or monthly, whichever comes first. Heavy-use equipment may need more frequent lubrication. Follow your Toyota equipment maintenance schedule.
Q: What type of grease should be used in the TO 00591-36910-81 zerk?
A: Use a multipurpose lithium-based grease rated for material handling equipment. Do not use automotive chassis grease or low-temperature grease unless specified in your equipment manual. Always check the equipment documentation for the correct grease type and NLGI grade.
Q: What are signs that a zerk fitting needs replacement?
A: Replace a zerk if it is stripped, cracked, bent, or if grease no longer pumps into the joint during lubrication. A damaged zerk allows dirt and moisture to enter bearing areas, causing premature wear. A replacement zerk like TO 00591-36910-81 restores proper lubrication access.
