SINOCMP 158-1553-001 Hydraulic Motor, for Eaton Char-Lynn T Series 1pc Gerotor Motor, Replacement for Sweeper Auger Winch Log Splitter, 1553-001 Aftermarket Hydraulic Drive Motor

Brand: SINOCMP

Features:

• 🔧 Part Number Verification - 158-1553-001 hydraulic motor cross-references for Eaton Char-Lynn T Series specifications. Before ordering this gerotor motor, verify your original component carries the 158-1553-001 number or T Series mounting pattern. The 1553-001 aftermarket motor matches the original displacement and port sizes for direct replacement.
• 🚜 High-Torque Applications - T Series motor provides high starting torque for demanding hydraulic systems. The 158-1553-001 gerotor design delivers smooth rotation at low speeds, ideal for sweepers, augers, winches, log splitters, and industrial conveyors. Use this hydraulic motor where your application requires consistent torque across varying loads.
• 🛠️ Mounting & Port Specs - The 158-1553-001 for Eaton Char-Lynn motor uses standard 2-bolt flange mounting (SAE A or B - verify your system). Ports are SAE O-ring boss type. This gerotor motor accepts hydraulic oil flow up to specified displacement. Before installing this 1553-001 motor, confirm your hydraulic system's flow and pressure ratings.
• ⚠️ Installation Precautions - Before installing this T Series hydraulic motor, relieve all pressure in the hydraulic circuit. The 158-1553-001 motor requires clean fluid - use a 10-micron filter in the return line. Purge air from the motor case before applying full flow. Do not exceed maximum pressure rating or case drain limits on this 1553-001 for Eaton replacement motor.
• ⚙️ Seal & Torque Requirements - This hydraulic drive motor includes new shaft seal pre-installed. When mounting the 158-1553-001 motor, use thread sealant on port fittings (not Teflon tape). Torque mounting bolts to SAE flange specifications. After installation, run the T Series motor at low speed to check for leaks before putting your equipment into full operation.

model number: Char-Lynn Eaton T Series

Part Number: 158-1553-001

Details: Product Specifications
Part Number: 158-1553-001 (cross-reference: 1553-001) Series: For Eaton Char-Lynn T Series (gerotor design) Displacement: Approx. 10-20 ci/rev (verify with factory spec for exact model) Maximum Pressure: 2000-2500 PSI (continuous) / 3000+ PSI (intermittent) Maximum Flow: 30-45 GPM (dependent on displacement version) Mounting Flange: SAE A or SAE B 2-bolt (confirm on your existing motor) Port Size: SAE O-ring boss (7/8-14 or 1-1/16-12 - verify) Rotary Shaft: Keyed straight shaft or splined (consult original motor specs) Seal Type: Nitrile or Viton shaft seal (oil-compatible) Weight: Approximately 15-25 lbs (depending on displacement)

Hydraulic Fluid Requirements
Fluid Type: Premium hydraulic oil (ISO VG 32, 46, or 68 depending on ambient temperature) Viscosity Range: 50-2000 SUS (10-440 cSt) at operating temperature Filtration: Minimum 10-micron absolute (return line) / 25-micron (pressure line) Temperature Range: -20°F to +200°F (-29°C to +93°C) with proper fluid grade Case Drain: Case must be drained to tank - not deadheaded

Gerotor Motor Operating Features
Rotation: Reversible (port direction determines rotation direction) Starting Torque: High torque at low RPM - no minimum speed requirement Speed Range: 0 to 1000+ RPM (dependent on flow and load) Efficiency: Volumetric efficiency decreases at high pressures Noise Level: Quieter than gear motors, similar to piston motors at moderate speeds

Critical Usage Notes
Do Not Deadhead Case Drain: The case drain line (if present) must be connected to tank with zero backpressure. Blocked case drain blows the shaft seal instantly. Use Correct Fittings: SAE O-ring boss fittings require metal-to-metal seal - no additional sealant needed. Teflon tape on O-ring boss threads causes leakage. Shaft Alignment is Critical: Misalignment between the158-1553-001 motor and driven load (sweeper brush, auger) causes shaft failure or seal leakage. Use flexible coupler or verify solid mount alignment (within 0.005-inch TIR). Filter Maintenance: This gerotor motor has tight internal clearances (0.001-0.003 inches). Contaminated fluid scores the gerotor stars, causing bypass and loss of torque. Change filters at manufacturer-recommended intervals. Pressure Spike Protection: Install relief valve in the circuit to protect the T Series motor from pressure spikes above maximum rating. Most motors tolerate intermittent spikes but repeated overpressure causes housing cracks.
