Frequently Asked Questions
Q: What is a zerk and what does the CT 217554 do?
A: The CT 217554 is a zerk fitting, also called a grease nipple or lube point. It allows pressurized grease to be injected into bearing and pivot joints on Crown electric trucks, maintaining lubrication for smooth operation and extended part life.
Q: Where is the CT 217554 zerk installed on Crown trucks?
A: Zerk fittings are located at critical pivot points such as mast tilt pins, load wheel bearings, steering pivot joints, and hydraulic cylinder attachment points. Crown truck lubrication diagrams specify the exact location and quantity of zerks for your model.
Q: What size grease can be injected through the CT 217554 zerk?
A: The CT 217554 is a standard zerk fitting designed for ISO NLGI Grade 2 general-purpose lithium grease. Use a standard grease gun with a properly fitting coupler. Consult your Crown truck manual for recommended grease specifications.
Q: How often should I lubricate through the CT 217554 zerk?
A: Crown trucks typically require lubrication every 250 to 500 operating hours depending on duty cycle and environmental conditions. Inspect zerk condition regularly; if the fitting becomes damaged or blocked, replacement is necessary for proper lubrication.
Q: What happens if the CT 217554 zerk becomes damaged or clogged?
A: A blocked or damaged zerk prevents grease from reaching critical bearing points, causing increased friction, noise, and premature wear of pivot components. Replacement zerks ensure smooth lubrication and prevent expensive joint damage.
Q: Are there different zerk sizes and is CT 217554 a standard size?
A: Zerk fittings come in standard and metric sizes. The CT 217554 is Crown-specified for particular pivot points. If your zerk is damaged or missing, confirm the exact fitting size and thread type with your truck manual to order the correct replacement.
