Frequently Asked Questions
Q: What is the TO 00591-07577-81 contact kit and what does it do?
A: The TO 00591-07577-81 is a Toyota OEM contact kit designed for 24VDC primary contactor assemblies in electric lift trucks. The contact kit contains matched silver-plated copper alloy contacts that carry electrical current when the contactor coil is energized. Contacts switch power to the lift trucks propulsion or hydraulic pump motor.
Q: Which Toyota electric lift truck models are compatible with the TO 00591-07577-81 contact kit?
A: The TO 00591-07577-81 fits multiple Toyota electric truck models equipped with 24VDC contactor systems. Cross-reference numbers include CL 7003192, CL 919410, GE 154FR, GE 154FR-CS, HY NA013890, PB 3304387K, YT 500863101, and PL K2096-10. If your truck uses a non-Toyota brand contactor, confirm dimensional and electrical compatibility before ordering.
Q: What are the material specifications of the TO 00591-07577-81 contact kit?
A: The contact kit contains copper alloy contacts with silver-plated tips for superior electrical conductivity and arc resistance. The insulator is phenolic material, which provides high dielectric strength and mechanical rigidity. M5 mounting threads secure the contacts to the contactor assembly. These materials are rated for industrial switching duty and high-cycle applications.
Q: What does the TO 00591-07577-81 supersede or replace?
A: The TO 00591-07577-81 supersedes part numbers TY 00591-53115-81 and TY 00591-57340-81. If your truck documentation references the older part numbers, the TO 00591-07577-81 is the current equivalent and direct replacement.
Q: How do I know when to replace the TO 00591-07577-81 contact kit?
A: Replace the contact kit if the contactor fails to energize the motor, if there is excessive arcing visible at the contacts, or if resistance testing shows high contact resistance (typically above 0.1 ohm). Contact wear occurs after millions of electrical cycles. If the truck loses power intermittently during normal operation, the contacts may be pitted and should be replaced.
Q: Is the TO 00591-07577-81 equivalent to contactors from Crown, Raymond, or other brands?
A: The TO 00591-07577-81 contact kit is Toyota-specific; however, equivalent contacts may be available for other brands using the cross-reference part numbers listed: GE 154FR, CL 7003192, and others. Verify that the contactor assembly mounting, terminal style, and electrical rating match your equipment before substituting parts from other manufacturers.
