SINOCMP 101-1032-009 Hydraulic Motor Replacement

The SINOCMP 101-1032-009 is a direct-swap replacement for Char-Lynn H Series motors with a 22.6 cu in/rev displacement, delivering 3602 lb-in at 152 RPM. It uses a 2-bolt SAE-A flange and a 3.248 inch pilot diameter, enabling straightforward bolt-on installation to compatible compressors, augers, and spreaders. Best for high-torque demands where a compact package is needed with reliable starting torque. Limitation: requires proper mounting patterns and line plumbing to match existing systems.
Buyers Products CM004P Hydraulic Spinner Motor

The CM004P is designed as a direct OEM replacement for common spreader motors, featuring a 4-bolt mount, 1 inch keyed shaft, and 1/2 inch NPT ports. It provides up to 650 in-lb continuous torque and supports 12 GPM continuous with 14 GPM intermittent flow, yielding speeds up to 969 RPM. Best for reliable spinner operation under heavy, wet materials in winter conditions. Caution: ensure compatibility with your specific spreader model and mounting pattern.
SINOCMP 101-1012-009 Hydraulic Motor Low Speed High Torque

This 101-1012-009 is a low-speed, high-torque replacement for Eaton Char-Lynn H Series with a 9.7 cu in/rev displacement. It offers 2059 lb-in at 353 RPM, with a max pressure of 1650 PSI and max continuous flow of 15 GPM. The 4-bolt flange with a 1.75 inch pilot diameter allows direct mounting to car wash brushes, harvesters, and similar equipment. Best for LSHT needs where space is limited but torque must be maintained. Limitation: operating at higher flow may require additional system tuning.
SINOCMP 101-1004-009 Replacement For Char-Lynn H Series

The 101-1004-009 is a ready-to-install motor with a 4-bolt flange, 1.75 inch pilot diameter, and a three-part gerotor design. It provides 2059 lb-in at 353 RPM and supports a max continuous pressure of 1650 PSI with up to 2250 PSI intermittent. It is a direct swap for Char-Lynn H Series models in industrial applications such as harvesters and marine equipment. Best for demanding LSHT tasks where robust torque is essential. Caution: verify mounting pattern and shaft size before ordering.
MuChaIOAK 5.9Inch Low Speed Hydraulic Motor

MuChaIOAK offers a low-speed hydraulic motor with a 5.9-inch design and 1 inch straight shaft. It emphasizes durability and environmental adaptability, performing under dusty and wet conditions. Best for compact LSHT setups that require rugged construction and ease of mounting in tight spaces. Caution: ensure the shaft diameter matches your drive components to avoid misalignment.
Buying Guide
Key considerations when choosing a low speed hydraulic motor:
- Torque versus speed: Prioritize continuous torque at low RPM for heavy-duty tasks; confirm the motor’s torque rating at your desired speed.
- Displacement and flow: Larger displacement typically means higher torque but may demand greater flow; ensure your hydraulic system supplies adequate GPM.
- Mounting compatibility: Check flange pattern, pilot diameter, and shaft size to ensure a direct swap without modifications.
- Pressure rating: Verify continuous and intermittent pressure ratings align with your system; exceeding ratings can reduce life or cause failures.
- Environment and durability: For harsh or dusty environments, look for protective housings and materials designed for durability.
- Installation and maintenance: Prefer motors with simple disassembly for maintenance and easy replacement of seals or bearings when available.
What to ask before buying
- Does the motor bolt directly to my current mounting pattern?
- Is the shaft length compatible with my drive gears or sprockets?
- What is the required hydraulic fluid temperature range for reliable operation?
- Can my existing hydraulic pump supply the necessary GPM at the required operating pressure?
Frequently Asked Questions
- What is a low speed high torque hydraulic motor?
Answer: A motor designed to deliver high torque at low rotational speeds, suitable for heavy-lift and traction tasks. - Why choose a direct swap motor?
Answer: It simplifies installation by matching mounting patterns, shaft sizes, and port configurations to existing equipment. - What determines motor durability in harsh environments?
Answer: Housing materials, seal quality, and protective enclosures influence longevity in dusty or wet conditions. - How does displacement affect performance?
Answer: Higher displacement increases torque potential at given pressure, but requires adequate hydraulic flow. - What should I verify before purchasing?
Answer: Mounting pattern, shaft diameter, port type, recommended flow, and maximum operating pressure. - Are these motors compatible with all Char-Lynn H Series models?
Answer: Not universally; confirm model compatibility and mounting standards with the product listing.
