Frequently Asked Questions
Q: What does the Toyota 00591-20758-81 hydraulic filter do?
A: The Toyota 00591-20758-81 is a hydraulic filter designed to remove contaminants from hydraulic fluid in forklifts and electric lift trucks. It protects the pump, valves, and actuators from particle damage and maintains system performance.
Q: How often should I replace the 00591-20758-81 hydraulic filter?
A: Replace the filter according to your equipment maintenance schedule, typically every 500 to 1000 operating hours or every six months, whichever comes first. If the filter element appears dark or clogged during inspection, replace it sooner. Contaminated hydraulic fluid reduces system efficiency and can cause valve damage.
Q: What is the correct installation procedure for this hydraulic filter?
A: Locate the filter housing on your lift truck hydraulic system. Depressurize the system using the relief valve. Unscrew or unbolt the old filter cartridge. Clean the filter seating surface. Install the new 00591-20758-81 filter and hand-tighten until the rubber seal contacts the base, then turn an additional three-quarter turn. Refill the reservoir if necessary and bleed air from the system.
Q: Can I use the 00591-20758-81 filter on non-Toyota equipment?
A: This is a Toyota OEM filter designed for Toyota forklifts and lift trucks. Do not use on non-Toyota equipment unless the filter port dimensions, flow rating, and micron rating match your equipment specifications. Incorrect filter sizing can cause system damage or bypass of contaminants.
Q: What happens if I delay replacing a clogged hydraulic filter?
A: A clogged filter reduces fluid flow, causing pump cavitation, pressure spikes, and overheating. The system may activate bypass valves, allowing unfiltered fluid to circulate. This leads to accelerated wear in the pump, proportional valves, and cylinders, ultimately causing costly repairs or equipment failure.
