Frequently Asked Questions
Q: What are the specifications for the 00591-27269-81 piston and pin?
A: The 00591-27269-81 is a piston and pin assembly with a 0.50-millimeter dimension specification. This component is a hydraulic pump or actuator subassembly part. The exact application and mounting configuration depend on your specific equipment model. Confirm your equipment type and part location before ordering to ensure correct fitment.
Q: Which lift truck or pallet jack models use this piston and pin?
A: The 00591-27269-81 piston and pin assembly is designed for Toyota material handling equipment. To confirm compatibility with your specific model, verify the equipment serial number or reference the OEM parts diagram. Contact our support team with your equipment details if you need cross-reference information or compatibility confirmation.
Q: What is the proper installation procedure for this component?
A: Installation of the piston and pin requires disassembly of the pump or actuator housing, removal of the worn component, and installation of the new 00591-27269-81 assembly. This is a precision component and should be installed by a qualified technician familiar with hydraulic systems. Improper installation can result in seal failure, pressure loss, and equipment malfunction. Do not attempt installation without proper training and documentation.
Q: What signs indicate this component needs replacement?
A: Replace the piston and pin if you observe hydraulic fluid leaking from the pump or actuator, loss of lifting pressure, sluggish operation, or noise from the hydraulic system. Scoring or pitting on the piston surface visible during disassembly also indicates replacement is necessary. Have a technician inspect the bore and seal surfaces before installing a new component to prevent repeat failure.
Q: How do I prevent premature failure of the piston and pin assembly?
A: Change hydraulic fluid at the manufacturer-recommended intervals, typically every 500 to 1,000 operating hours. Use only the correct ISO-grade hydraulic fluid specified for your equipment. Keep the hydraulic fluid clean by replacing filters regularly and checking fluid condition quarterly. Maintain proper hydraulic system pressure and temperature to avoid seal degradation and component wear.
