This kit is designated as M-SK (multi-seal) and is designed for 821E steering cylinders on cylinder 87307850 with serial range 8/06 and later. Verify your cylinder type and serial number match before ordering.
Q: What equipment is the JIC-87363451 compatible with?
A: This seal kit is designed for steering cylinders on model 821E equipment using cylinder number 87307850. The M-SK designation indicates a multi-seal design. Confirm your steering cylinder is exactly 87307850 with serial number 8/06 or later to ensure compatibility.
Q: What is the difference between the M-SK and standard SK seal kit designs?
A: The M-SK designation indicates a multi-seal design that provides additional sealing redundancy compared to standard single-seal designs. This configuration offers improved reliability and longer service life for steering applications. The M-SK is specifically engineered for cylinder 87307850 and should not be substituted with standard SK kits.
Q: What maintenance should be performed on 821E steering cylinders?
A: Steering cylinders should be inspected regularly for oil weeping or external leakage. Loss of steering responsiveness, sluggish motion, or visible contamination around the rod indicates seal wear. The M-SK multi-seal design is meant for planned replacement intervals to maintain steering precision and reliability.
Q: Can the JIC-87363451 be cross-referenced to other steering cylinder seal kits?
A: The JIC-87363451 M-SK design is specific to cylinder 87307850 on 821E equipment with the 3.25-inch bore and 1.75-inch rod. Do not attempt to substitute standard seal kits or kits designed for different cylinder numbers. The multi-seal design requires exact matching of cylinder type.
