Frequently Asked Questions
Q: What does the 00590-4345071 contactor do in an electric pallet jack?
A: This is the main contactor that switches power to the hydraulic pump motor. It is a 24VDC solenoid-operated contactor rated for 100A at 24VDC resistive load and is designed for continuous duty operation in Toyota 7HWB23 series electric pallet jacks.
Q: What is the voltage and amp rating for this contactor?
A: The contactor operates on 24VDC continuous duty with a 100A contact rating at 24VDC resistive load. Do not apply higher or lower voltages; doing so will damage the solenoid coil and cause the contactor to fail.
Q: What part numbers does the 00590-4345071 replace?
A: The 00590-4345071 replaces the older part number 00590-43450-71 and supersedes 00590-43141-71. The equivalent cross-reference is TY00590-43450-71. This is a direct one-for-one replacement for these legacy part numbers.
Q: What mounting system does this contactor use?
A: This contactor features a bolt-mount design with a 4-hole mounting pattern (3.75 inch x 2.25 inch center-to-center). It bolts directly to the power distribution board or contactor mounting bracket inside the electric pallet jack control box.
Q: What are symptoms of a failing main contactor?
A: Common failure symptoms include: pump motor does not start when lift button is pressed, audible clicking but no pump operation, truck lifts intermittently, or control buttons become unresponsive. If diagnosed as failed, the contactor must be replaced; it cannot be repaired.
Q: Is the 00590-4345071 compatible with other manufacturer pallet jacks?
A: This is a Toyota factory-spec contactor specified for Toyota 7HWB23 series electric pallet jacks. Do not use on Crown, Raymond, Yale, or other brand lift trucks. Using a non-compatible contactor will cause electrical damage and void equipment warranties.
