Frequently Asked Questions
Q: What makes and models is the CR 87901 compatible with?
A: The CR 87901 is compatible with Crown electric lift trucks including the RR 5000, RD 5000, RR 5200, RD 5200, and 5000S models. Always verify your equipment model and master cylinder type against the Crown parts manual before ordering.
Q: What materials are used in the CR 87901 rebuild kit?
A: The CR 87901 includes a steel piston with an specified surface finish to ensure proper sealing and durability. The internal seals and dust boot are made from materials that meet industry standards for hydraulic performance.
Q: How do I know if the CR 87901 is the right rebuild kit for my lift truck?
A: The CR 87901 is designed to restore sealing and pressure integrity in master cylinders on compatible Crown electric lift trucks. If you experience reduced hydraulic pressure, slow or no lift response, or fluid leakage around the piston rod, this rebuild kit may be suitable. Consult your Crown parts manual for confirmation.
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 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.
