109-1118-006 Char-Lynn Eaton 4000 Series Geroler Motor

Product Overview

The 101 / 106 / 104 / 109 series and specific models 109-1118-006, 109-1118-002, 109-1116-006, 109-1478-006 are Char-Lynn / Eaton (Danfoss) 4000 Series low-speed high-torque Geroler disc-valve orbital hydraulic motors. Featuring precision Geroler rotor sets and disc valve design, they deliver high starting torque, high volumetric efficiency, and excellent side-load capacity. Fully interchangeable with genuine Char-Lynn / Eaton units and subjected to 100% simulated operating condition testing, these motors provide reliable performance for medium- to heavy-duty mobile and industrial applications.

Key Technical Advantages

• Precision Geroler rotor set and disc valve structure deliver high volumetric efficiency and smooth low-speed operation with consistent performance over the motor’s service life.
• High starting torque and excellent side-load capacity ideal for heavy-load starting and high side-load applications.
• Robust bearings and high-pressure shaft seal design support elevated return pressure for extended service life.
• Full drop-in interchangeability with genuine Char-Lynn / Eaton units plus 100% simulated duty-cycle testing ensure reliable high-pressure, high-flow performance while reducing maintenance costs.

Application Areas

Agricultural machinery, construction attachments, sweepers and snow removal equipment, forestry machinery, conveyor systems, material handling equipment, industrial drives.

Expert Maintenance Tips

Verify system cleanliness and oil viscosity before installation. Ramp pressure gradually on start-up to avoid dry running. Periodically inspect shaft seals and bearings. Prefer verified interchangeable units for replacement to ensure exact port and flange match. Observe intermittent duty time limits and maintain proper oil cleanliness to maximize service life.
