Frequently Asked Questions
Q: What is the TO 00591-39418-81 contact tip stationary used for?
A: The TO 00591-39418-81 is a stationary contact tip component in Toyota electric lift truck contactors or relays. It forms one half of an electrical contact pair and remains fixed while the moving contact engages and disengages during circuit switching. Verify your truck model requires this specific stationary contact tip.
Q: Which Toyota lift trucks use the TO 00591-39418-81 stationary contact tip?
A: This is a Toyota OEM stationary contact tip designed for specific electric forklift or reach truck contactor assemblies. Confirm your truck model, production year, and electrical system configuration match this part number. Consult the Toyota parts manual for your equipment to verify compatibility.
Q: What material is the TO 00591-39418-81 contact tip made from?
A: Stationary contact tips in industrial contactors are typically manufactured from silver alloy, copper alloy, or composite materials designed for high-current switching with minimal arcing and contact erosion. The specific material for the TO 00591-39418-81 is determined by Toyota for this contactor application.
Q: What symptoms indicate the stationary contact tip needs replacement?
A: Worn stationary contact tips cause erratic power delivery, intermittent motor engagement, or visible arcing at the contactor. Pitting, burning, or flattening of the contact surface reduces contact pressure and electrical conductivity. Replace stationary contact tips as part of contactor maintenance or when contact surfaces show burn damage.
Q: How often should stationary contact tips be inspected?
A: Inspect stationary contact tips annually or after 1500 to 2000 operating hours in high-duty applications. Heavy-use lift trucks with frequent starting cycles experience faster contact wear. Look for pitting, burning, or material erosion on contact surfaces. Plan replacement before contact failure interrupts truck operation.
