Frequently Asked Questions
Q: What are the material specifications for the MU 90109 steer wheel axle?
A: The MU 90109 is a precision-machined carbon steel rod designed for steer wheel axle service. It meets ASTM A108 standards with axle straightness tolerance of plus or minus 0.005 inch. Surface finish is turned, ground, and polished to 1.6 micrometers Ra (average surface roughness). The service factor is rated for 1.0 continuous service.
Q: Which Multiton pallet jack models use the MU 90109 axle?
A: The MU 90109 is engineered for Multiton TM, M, and J Series manual pallet jacks. This axle provides structural support for steer wheel assemblies on these models. Verify your machine series and axle dimensions before ordering replacement parts.
Q: What causes premature failure of the MU 90109 axle?
A: Bent or cracked axles typically result from overload conditions, dropped loads, or impact with obstacles during jack operation. Misalignment from worn steer wheel bearings or hub damage forces the axle to carry uneven loads. Rust and corrosion can weaken the carbon steel over time in damp storage environments.
Q: How do I diagnose a damaged MU 90109 axle during operation?
A: Symptoms of axle damage include steering that is hard to control, uneven steer wheel wear, excessive play in the steering mechanism, or audible clunking during directional changes. A bent axle prevents proper wheel alignment and creates binding. Inspect the axle visually for cracks, bending, or twisting before use.
Q: Is there a stainless steel version of this axle available?
A: Yes, the MU 90109-SS is a stainless steel equivalent of the MU 90109. The stainless version resists corrosion and rust significantly better, making it suitable for cold storage, outdoor environments, or operations where moisture exposure is frequent. Both versions are compatible with TM, M, and J Series steer wheel assemblies.
