Frequently Asked Questions
Q: What is contact part 00591-04787-81?
A: Contact 00591-04787-81 is an electrical component used in electric lift truck motor systems. Contacts conduct electrical current between motor terminals and the motor windings. Worn or corroded contacts reduce electrical flow, causing loss of motor power or intermittent operation.
Q: Which Toyota electric lift trucks require the 00591-04787-81 contact?
A: Contact 00591-04787-81 is used in specific Toyota electric lift truck models. Confirm your truck model and motor specification against the parts diagram. We can verify compatibility with your equipment serial number before you order.
Q: What happens if the 00591-04787-81 contact fails or corrodes?
A: A failed or corroded contact interrupts electrical flow to the motor, resulting in loss of lift power, intermittent motor shutdowns, or complete motor failure. You may notice sparking at the motor terminals or a burning smell. Replace corroded contacts immediately to prevent further motor damage.
Q: How do you clean or restore a corroded 00591-04787-81 contact?
A: Minor corrosion can sometimes be cleaned with a contact cleaner and a soft brush or cloth. However, if contacts show pitting, significant corrosion, or burn marks, replacement is the safest option. Do not file or sand the contact surfaces, as this damages the contact material. Replace the entire 00591-04787-81 contact.
Q: Is the 00591-04787-81 contact user-replaceable?
A: Contact replacement typically requires disconnecting the motor power and removing the motor cover or housing. The job is straightforward for a technician familiar with electric motor systems. If you are unsure, contact us for step-by-step guidance or consider professional service to avoid electrical hazards.
Q: What causes contacts to corrode and how do you prevent it?
A: Corrosion occurs from moisture, salt spray, or poor electrical connections that cause arcing. Prevent corrosion by maintaining dry storage, protecting motors from water spray, and keeping all electrical connections clean and tight. Inspect contacts annually and replace the 00591-04787-81 if you see discoloration or rust. Store replacement contacts in dry conditions before installation.
