    Frequently Asked Questions

    Q: What are the specifications of the JIC-87434291 seal kit?
    A: The JIC-87434291 is a P-UB-10 seal kit with a bore of 4.5 inches and rod diameter of 2.5 inches. It is designed for 521D loader bucket cylinders with Z-BAR configuration using cylinder 87366674. Verify your equipment model is 521D, application is loader bucket Z-BAR, and cylinder is 87366674 before ordering.

    Q: Which loader models and equipment types use the JIC-87434291?
    A: This seal kit is designed for 521D loader bucket Z-BAR cylinders (cylinder 87366674) with serial number range starting JEE0135501 and later. The 521D is an older generation loader model. Confirm your equipment model and serial range match before purchasing this seal kit.

    Q: What is the typical service life of the JIC-87434291 seal kit?
    A: Bucket cylinders in the 521D loader experience heavy digging and material handling cycles. Seal kit lifespan typically ranges from 1200 to 2500 operating hours depending on load intensity, material density, and frequency of cycles. Harsh digging conditions accelerate seal wear.

    Q: What failure symptoms indicate the JIC-87434291 is needed?
    A: Bucket cylinder seal failure manifests as external oil leakage from the rod end, slow bucket response or sluggish movement, inability to hold load (drift), or visible hydraulic contamination. Any of these conditions on a 521D bucket cylinder indicates seal replacement is required.

    Q: Are there cross-references or alternative part numbers for the JIC-87434291?
    A: The JIC-87434291 is engineered specifically for the 521D loader bucket cylinder 87366674 with the 4.5-inch bore and 2.5-inch rod. Do not cross-reference this kit to other loader models or bucket cylinder sizes. Using the correct seal kit specification ensures proper sealing under bucket load pressure.
