Frequently Asked Questions
Q: What is the purpose of precision shim TO 00590-43404-71?
A: This precision-ground steel shim controls bearing preload and assembly spacing in the drive system of Toyota 7HBW23 electric pallet trucks. Shims maintain proper clearance and prevent bearing rattle while ensuring correct rotational alignment in the drive assembly.
Q: Which Toyota pallet truck models use this shim?
A: The TO 00590-43404-71 shim is designed for Toyota 7HBW23 series electric pallet trucks. Cross-reference formats include TY00590-43404-71 and TY 00590-43404-71. Verify your truck model against the parts catalog Section 5-13 assembly reference before ordering.
Q: What material is this shim made from?
A: This shim is manufactured from precision-ground carbon steel to OEM specifications. The hardened steel construction resists wear from repeated bearing preload cycles and maintains dimensional accuracy throughout the service life of the pallet truck.
Q: Are shim thickness tolerances critical?
A: Yes. This shim is precision-ground to exact OEM tolerances because even small thickness variations affect bearing preload, drive shaft alignment, and motor efficiency. Substituting non-OEM or incorrect shim thickness can cause bearing failure, binding, or excessive play.
Q: Can I reuse the old shim or must I replace it?
A: If the shim shows visible wear, scoring, or deformation, it must be replaced with a new OEM shim. Reusing a worn or damaged shim will not maintain proper bearing preload and will lead to premature bearing failure and increased operating noise.
