104-1065-006 101-1018-009 Char-Lynn Eaton Low Speed Motor

Product Overview

The 158 / 104 / 101 series and specific models 104-1065-006, 104-1388-006, 158-1464-001, 158-3861-001, 101-1018-009 are Char-Lynn / Eaton (Danfoss) low-speed high-torque orbital hydraulic motors (H-Series and 2000 Series Gerotor / Geroler). Featuring precision gear rotor designs, they deliver high starting torque, high volumetric efficiency, and reliable radial load capacity. Fully interchangeable with genuine Char-Lynn / Eaton units and subjected to 100% simulated operating condition testing, these motors are ideal for medium-light to medium-duty mobile and industrial applications.

Key Technical Advantages

• Precision Gerotor / Geroler rotor set minimizes internal leakage, delivering high volumetric efficiency and smooth low-speed operation.
• High starting torque characteristics ideal for frequent start-stop and heavy-load starting applications.
• Robust bearing and shaft seal design supports elevated side loads and return pressure for extended service life.
• Full drop-in interchangeability with genuine Char-Lynn / Eaton motors plus 100% simulated duty-cycle testing ensure reliable performance while reducing maintenance costs.

Application Areas

Agricultural machinery, construction attachments, conveyor and feeding systems, sweepers, light-to-medium vehicle drives, micro excavators and compact equipment, industrial automation.

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.
