Frequently Asked Questions
Q: What bore and rod specifications does the JIC-8605262 seal kit have?
A: The JIC-8605262 is a P-UB-10 seal kit with a bore of 4.75 inches and rod diameter of 3 inches. It is designed for loader lift cylinders on models 721E, 721F, and 721D Z-BAR/XT loaders. Verify your loader model and cylinder number (87318066 or 87319194 depending on model) match before ordering.
Q: Which loader models and cylinders does the JIC-8605262 fit?
A: This seal kit covers loader lift cylinders on model 721E (cylinder 87318066), 721F (cylinder 87319194), and 721D Z-BAR/XT loaders (cylinders 8605290 or 87318066 depending on serial range 01/03 and later). Confirm your exact loader model and serial number to ensure the correct cylinder number matches.
Q: How durable are the seals in the JIC-8605262 kit under loader lift duty?
A: Loader lift cylinders operate under high-pressure, high-cycle duty. Seals in this kit are designed for rated pressure conditions and typical load-handling applications. Expected lifespan is 2000 to 4000 operating hours depending on load capacity utilization, environmental factors, and maintenance frequency.
Q: What symptoms indicate the JIC-8605262 seal kit is needed?
A: Signs of seal failure include visible hydraulic leakage around the cylinder rod, reduced lift speed or power, external oil contamination, or cylinder drift (uncontrolled lowering). Any of these symptoms on a 721-series loader lift cylinder warrant seal kit replacement as preventive maintenance.
Q: Are there alternative part numbers or cross-references for the JIC-8605262?
A: The JIC-8605262 is a specific seal kit for P-UB-10 cylinders on 721-series loaders. Do not substitute with seal kits for other bore/rod combinations or loader models. Always confirm the cylinder number and the 4.75-inch bore and 3-inch rod match your equipment before ordering.
