104-1217-006 Char-Lynn 2000 Series Orbit Motor 101.6cc 3000psi

Product Overview

The 104-1217-006 is a standard-displacement model in the Eaton/Char-Lynn 2000 Series of low-speed high-torque geroler hydraulic motors, featuring a geometric displacement of 101.6 cm³/rev (6.2 in³/rev) with Geroler roller-stator and disc valve distribution. As a standard-duty 2000 Series unit, it delivers true bi-directional operation with a maximum inlet pressure of 4500 psi, continuous working pressure of 3000 psi, rated output torque of 2611 in-lb, and maximum speed of 742 rpm @ 20 gal/min continuous flow.

This motor is a direct drop-in replacement for Eaton/Char-Lynn 2000 Series OEM motors of matching specification, with fully interchangeable mounting flange, shaft, and port locations. The 2000 Series employs a three-zone pressure design ensuring identical performance in both forward and reverse rotation. Every unit undergoes 100% simulated load-condition bench testing before shipment.

Key Technical Advantages

1. Disc Valve Distribution with Industry-Lowest Pressure Drop (2000 Series)

The 104-1217-006, 104-3155-006, and 104-1611-006 all employ the signature Char-Lynn disc valve architecture, officially described by Eaton as the “lowest pressure drop motor in the industry.” The valve plate and rotor end face feature automatic wear compensation, maintaining tight contact over extended service life. Compared to conventional shaft-distribution designs, the disc valve structure significantly reduces throttling losses during oil distribution. The Geroler roller-stator set provides high volumetric efficiency and energy savings.

2. Spool Valve Distribution with Compact Integrated Design (T, H, S Series)

The 158-1463-001, 101-2861-009, and 103-1027-012 employ spool valve distribution with the valve integrated into the output shaft. This integrated structure reduces part count and potential leakage paths compared to conventional separate valve plate designs, while improving distribution precision. The symmetry of spool valve distribution ensures identical performance in forward and reverse rotation, with no pronounced pressure shock or torque fluctuation during direction changes.

3. Dual Journal Plain Bearings with Long-Life Sealing System

The 158-1463-001 and 101-2861-009 use dual front and rear journal plain bearings with low friction loss, simple economical maintenance, and stable rotation under frequent start-stop cycles. The NBR high-pressure shaft seal combined with an external dust seal provides double protection against internal and external oil seepage, maintaining stable output pressure under continuous light-medium load cycles.

4. Cast Iron Housing and High Power Density

All series feature cast iron housings for excellent rigidity and durability. The 104-1611-006 delivers 765 N·m of continuous torque at 306.6 cm³/rev displacement, while the 104-1217-006 delivers 2611 in-lb of rated torque at 101.6 cm³/rev displacement. Standardized mounting flanges and multiple shaft options (straight keyed, splined) allow flexible adaptation across different drive requirements.

Application Areas

• Lawn & Garden Equipment: Riding lawn mowers (158-1463-001, 101-2861-009), Bobcat brush cutters (104-3155-006)

• Material Handling: Conveyor drives, winch and hoist mechanisms

Expert Maintenance Tips

Installation Guidelines:

• Before installation, verify system oil cleanliness meets ISO 18/13 or NAS Class 9 or better. The disc valve face is sensitive to particulate contamination — install a 10μm filter upstream of the motor inlet.

• The 158-1463-001 and 101-2861-009 have no built-in anti-reverse check valve. For mower blade or spray pump applications requiring anti-runaway protection, an external one-way valve must be installed. Ensure the 2-bolt SAE-A flange and equipment interface surfaces are clean and flat during installation.

• The 103-1027-012 uses a 25.4 mm straight shaft with Woodruff key and 1/2-14 NPTF dryseal pipe thread ports. Ensure proper fit precision between the key and equipment-side keyway. Shaft alignment must be within 0.05mm.

• The 104-1611-006 uses a 31.75 mm straight keyed shaft with a threaded end. Ensure the 4-bolt standard flange (82.6 mm pilot) and equipment interface surfaces are clean and flat during installation.

• During initial commissioning for all models, run at no more than 30% of rated pressure for at least 30 minutes of no-load break-in.

Operational Maintenance:

• Normal operating oil temperature should not exceed 82°C (180°F). The recommended maximum system working temperature for the 158-1463-001 and 101-2861-009 is 180°F.

• Use premium anti-wear hydraulic oil with viscosity maintained at 20-43 cSt at operating temperature. The 158-1463-001 and 101-2861-009 recommend 70 SSU (Saybolt Universal Seconds).

• Inspect volumetric efficiency every 2,000 hours or every 12 months. If efficiency drops by more than 10% of rated value, disassemble and inspect the valve plate (2000 Series) or spool valve assembly (T/H/S Series) and rotor-stator set.
