Frequently Asked Questions
Q: What is the MO 120E21 Locking Ring used for?
A: The MO 120E21 is an OEM steel retaining ring designed to secure axles or wheel assemblies on Mobile ECO I-55 series manual pallet jacks. It prevents axial movement of wheels and maintains proper load wheel or steer wheel positioning on the shaft.
Q: What equipment is the MO 120E21 compatible with?
A: The MO 120E21 is compatible with Mobile ECO I-55 series pallet jacks, including alternate model designations ECO I55 and ECO I 55. It fits frame and wheel subassemblies engineered for ECO I-55 specifications.
Q: How do I know when a locking ring needs replacement?
A: Replace the MO 120E21 if the wheel shifts or rocks excessively on the axle, if the ring is visibly deformed or cracked, or if wheels are drifting side-to-side under load. A failing locking ring cannot maintain proper wheel alignment and must be replaced immediately.
Q: Is the MO 120E21 a consumable part that wears out regularly?
A: The MO 120E21 is a semi-permanent retention component. Under normal operation, it does not require routine replacement. However, removal and reinstallation during wheel service or if the ring becomes deformed due to impact or improper axle handling may necessitate replacement.
Q: Can the MO 120E21 be reused if it is removed during wheel service?
A: Inspect the ring carefully after removal. If it shows no visible deformation, cracks, or loss of tension, it may be reused. However, if the ring was damaged during removal or shows any signs of wear or fatigue, install a new MO 120E21 to ensure proper axle retention.
