Motor Specifications:
The guide details a range of fixed displacement motors with displacements from 24 in³ to 111 in³. These motors offer two-speed operation with external valving and have starting and stall torques equal to 90-94% of theoretical torque. They can operate continuously at speeds up to 1,000 RPM and handle up to 190 HP. The motors conform to a modified SAE 'D' mounting specification and weigh between 171 lbs and 205 lbs.

Features of the 37-57 Series 4-Port Motor:
The motors are designed with a vane crossing vane for higher volumetric and mechanical efficiencies. They have a pressure balanced rotating group to reduce cross port leakage and increase efficiency. The motors can rotate in either direction and maintain smooth operation across their pressure and speed range.

Bearing and Load Capacities:
The bearings can accept radial loads as per the radial capacity charts. Thrust loading is not recommended for standard motors but is possible with thrust capable motors. The guide provides detailed charts for radial and thrust load capacities.

Performance Data:
The document includes performance charts for torque, power, and flow at various pressures and RPMs for both 26 CID and 37 CID motors. The motors are noted for producing flat torque curves with starting and stall torque close to theoretical values.

Fluid and Filtration Requirements:
Recommended fluids should contain high-quality rust, oxidation, and foam inhibitors, with viscosity maintained between 100 and 200 SUS. Fluid temperature should not exceed 180°F. Filtration should be at a minimum of 25 microns.

Warranty:
Rineer Hydraulics, Inc. offers a limited warranty for defects in material and workmanship, valid for 455 days from shipment or one year from first use. The warranty excludes consequential damages and is void if the product is dismantled or used beyond its capabilities.
