161-0085-005 6682034 Char-Lynn Eaton VIS Hydraulic Drive Motor

Product Overview

The 161-0085-005, 6682034, 177-0085-005, 161-0085, 168-0044-005, 120-1015-003, and 177-0085 models are Char-Lynn / Eaton (Danfoss) VIS (Valve-In-Star) Series low-speed high-torque hydraulic drive motors. Featuring advanced Valve-In-Star technology and precision Geroler design, they deliver high starting torque, high volumetric efficiency, and excellent radial load capacity. Specifically engineered for skid-steer loader drive systems, these motors are fully interchangeable with genuine Char-Lynn / Eaton and Bobcat OEM specifications and subjected to 100% simulated operating condition testing for reliable performance under high-pressure, high-load conditions.

Key Technical Advantages

• Advanced VIS (Valve-In-Star) precision design optimizes pressure distribution and efficiency, delivering higher pressure capability and extended service life.
• High starting torque and smooth low-speed performance specifically optimized for skid-steer loaders and frequent start-stop, heavy-load drive applications.
• Robust bearing and shaft seal system supports high side loads and harsh operating conditions, reducing maintenance requirements.
• Full drop-in interchangeability with genuine Char-Lynn / Eaton / Bobcat units plus 100% simulated duty-cycle testing ensure reliable performance and minimized downtime.

Application Areas

Bobcat and other brand skid-steer loader drive systems, compact loaders, construction equipment wheel drives, material handling, and site preparation machinery.

Expert Maintenance Tips

Verify system cleanliness and oil specifications per OEM requirements before installation. Ramp pressure gradually on start-up to avoid dry running. Periodically inspect shaft seals, bearings, and mounting bolt torque. Prefer verified interchangeable units for replacement to ensure exact flange and port match. Maintain proper oil cleanliness and viscosity to maximize VIS motor service life.
