Frequently Asked Questions
Q: What is the Toyota BT Seal Kit 00591-31550-81 designed for?
A: The 00591-31550-81 is an OEM hydraulic cylinder seal kit engineered for Toyota and BT brand manual pallet jacks. The kit includes elastomeric seals, dust seals, and backup rings compatible with cylinder bores from 1.25 to 2.00 inches.
Q: What hydraulic fluid should I use with the 00591-31550-81 seal kit?
A: The 00591-31550-81 is designed for ISO VG 32 hydraulic oil only. Using incorrect fluid viscosity or incompatible oil types will compromise seal performance and accelerate wear. Always confirm your pallet jack hydraulic specification before refilling.
Q: What is the maximum pressure rating for the 00591-31550-81?
A: The 00591-31550-81 seal kit is rated for hydraulic pressures up to 3000 PSI. The Shore A80 elastomeric polymer seals and backup rings maintain reliable sealing across the full 1.25 to 2.00 inch cylinder bore range at rated pressure.
Q: How do I know when the 00591-31550-81 seal kit needs replacement?
A: Replace the 00591-31550-81 when you observe hydraulic leakage from the cylinder rod, loss of lifting pressure, or the pallet jack does not hold load consistently. Dust seals prevent contamination; if visible damage is present, replacement is necessary.
Q: Does the 00591-31550-81 include all components needed for installation?
A: The 00591-31550-81 is a complete seal kit and includes elastomeric seals, dust seals, and backup rings. Verify your cylinder bore size and rod diameter match before installation to ensure proper fit and function.
