MO 18E329

Frequently Asked Questions

Q: Which Mobile ECO I-55 models does the MO 18E329 ball fit?
A: This ball is compatible with Mobile ECO I-55 pallet jacks with newer hydraulic units. The model may also be listed as ECO I55 (Newer) Hydraulic Unit or ECO I 55 (Newer) Hydraulic Unit. Do not use this part on standard or older ECO I-55 hydraulic assemblies without confirming compatibility.

Q: What does this ball component do in the pallet jack?
A: This ball is a precision component in the hydraulic control or valve assembly. It typically serves as a check ball or directional control element that regulates hydraulic fluid flow or prevents backflow in the system.

Q: Is this ball compatible with older Mobile ECO I-55 hydraulic units?
A: No. The MO 18E329 is specifically manufactured for newer Mobile ECO I-55 hydraulic units. Older ECO I-55 models use different ball specifications. Installing this ball in incompatible hydraulic assemblies will result in malfunction or system failure.

Q: What material is the MO 18E329 ball made from?
A: This ball is manufactured from hardened steel or corrosion-resistant material designed to withstand repeated cycling and hydraulic fluid exposure. The ball surface maintains a precise spherical shape critical for proper valve operation.

Q: When should I replace the MO 18E329 ball?
A: Replace this ball if the pallet jack exhibits loss of lifting pressure, fails to hold a load, or demonstrates sluggish or erratic control response. Wear or damage to the ball surface compromises the hydraulic seal integrity and directional control function.
