Frequently Asked Questions
Q: What are the dimensions and specifications of the AC 74934289 idler caster wheel?
A: The AC 74934289 is a polyurethane idler caster wheel with a 4 inch diameter and 2.5 inch width. It features a 1/4 inch steel core, 95A Shore durometer polyurethane tread, and provides ±0.5 inch height adjustment with vibration-damping polyurethane spring block.
Q: What equipment types use the AC 74934289 caster wheel?
A: This polyurethane idler caster wheel is engineered for stabilizer and caster assembly applications on Allis Chalmers electric lift trucks. Verify mounting dimensions match your equipment before ordering.
Q: Why is the 95A durometer polyurethane material used on this wheel?
A: The 95A Shore durometer polyurethane provides a balance of wear resistance and load support for material handling equipment. This hardness is suitable for general warehouse and facility conditions. The vibration-damping spring block reduces shock transmission to equipment bearings.
Q: What is the expected lifespan of the AC 74934289 wheel?
A: Lifespan depends on load, floor conditions, and usage frequency. Polyurethane idler wheels typically last 1 to 3 years in moderate service. Inspect for wear and flatten edges regularly. Replace when tread depth decreases or vibration increases.
Q: Are there cross-reference or equivalent part numbers for the AC 74934289?
A: No documented cross-reference part numbers are published for the AC 74934289. This is an original equipment manufacturer part for Allis Chalmers. Use the exact SKU when ordering to ensure correct fitment.
