MO M521

Frequently Asked Questions

Q: What equipment does the MO M521 clevis fit?
A: The MO M521 is a clevis bracket assembly for manual pallet jacks produced by Mobile, designed for the ML45 Mini and ML45 Miney model lines. Confirm your equipment model before purchase.

Q: How does the MO M521 differ from the MO M520 clevis?
A: Both MO M521 and MO M520 are clevis connectors for Mobile ML45 models. Differences may include pin hole diameter, clevis arm width, or load rating. Measure existing components or consult the equipment manual to determine which part is correct for your configuration.

Q: What is the role of the clevis in the pallet jack lift cylinder assembly?
A: The clevis connects the hydraulic cylinder to the pallet jack frame. It enables vertical lift movement by anchoring one end of the cylinder and distributing load forces through the frame structure.

Q: What failure modes require replacement of the MO M521?
A: Replace the clevis if the bracket is cracked or permanently bent, if pin holes are stripped or enlarged, if corrosion creates structural weakness, or if the lift cylinder does not align properly with the frame.

Q: Can the MO M521 be used as an interchangeable part with other pallet jack brands?
A: The MO M521 is specifically designed for Mobile manual pallet jacks. It is not recommended for use with Crown, Toyota, Raymond, or other OEM equipment without direct dimension verification and engineering confirmation.

Q: How long does an MO M521 clevis typically last in standard warehouse operations?
A: Service life depends on load frequency, environmental conditions, and maintenance practices. In typical warehouse use, a properly maintained clevis lasts several years. Corrosive environments or high-frequency lifting may reduce lifespan. Regular visual inspection for cracks and corrosion extends overall equipment reliability.
