Q: What are the cross-reference part numbers for the CR 87901?
A: The CR 87901 supersedes Crown part numbers 087901 and CR087901. It is equivalent to CR-087901. Always verify your current part number against these cross-references to confirm you have the correct rebuild kit for your master cylinder.
Q: What equipment does the CR 87901 master cylinder kit fit?
A: The CR 87901 is designed for Crown electric lift trucks equipped with hydraulic master cylinders. This rebuild kit restores sealing and pressure integrity. Verify your equipment model and master cylinder type against the Crown parts manual before ordering.
Q: What symptoms indicate a master cylinder rebuild is needed?
A: Signs of master cylinder failure include reduced hydraulic pressure, slow or no lift response, fluid leakage around the piston rod, or spongy brake or control pedal feel. The CR 87901 kit restores sealing and pressure by replacing internal wear items. If pressure remains low after rebuild, consult our parts team.
Q: What is the material specification for the CR 87901 piston?
A: The CR 87901 kit includes a steel piston with OEM-specified surface finish. This finish ensures proper sealing and durability. Do not use substitute materials or finishes as they may not meet pressure and wear specifications for your lift truck.
