Frequently Asked Questions
Q: What does the AC 4907130 coupling connect?
A: The AC 4907130 is a mechanical coupling designed for Alice Chalmers electric lift truck drive assemblies, typically connecting motor shafts to transmission or pump shafts. It allows controlled power transmission while accommodating minor shaft misalignment.
Q: What are the shaft diameter and bore specifications for AC 4907130?
A: The AC 4907130 has specific shaft bore sizes engineered for Alice Chalmers equipment. Verify your equipment model and shaft diameters match before ordering. Incorrect bore size will prevent proper installation and cause equipment failure.
Q: What material is the AC 4907130 coupling made from?
A: The AC 4907130 is manufactured from cast iron or steel with elastomeric insert elements (typically rubber or polyurethane) to absorb vibration and dampen shock loads. This design protects motors and transmissions from impact damage.
Q: How long does the AC 4907130 coupling typically last?
A: Couplings last 4-8 years in typical material handling use. Lifespan depends on load, alignment, and vibration. Worn elastomeric inserts cause noise, vibration, and eventual coupling failure. Replace if you hear grinding or excessive vibration during operation.
Q: Are there equivalent couplings from other manufacturers?
A: The AC 4907130 is specific to Alice Chalmers equipment. Crown, Toyota, Raymond, and other brands use different coupling designs and specifications. Confirm your equipment model and shaft specifications before ordering alternatives.
Q: What happens if the coupling fails?
A: A failed coupling breaks drive power transmission, preventing the truck from moving or lifting. Continued operation with a damaged coupling causes further motor and transmission damage. Replace immediately if the coupling breaks or cracks.
