Drawing upon decades of hydraulic engineering expertise, this motor represents a pinnacle of design, material science, and operational efficiency, tailored for the demanding conditions inherent in commercial spreading applications.\u003c\/p\u003e\n\n\u003ch3\u003eUnderstanding Hydraulic Motor Fundamentals\u003c\/h3\u003e\n\u003cp\u003eAt its core, a hydraulic motor serves as a transducer, converting hydraulic energy (fluid flow and pressure) into mechanical rotational energy (torque and speed). This conversion is achieved through a controlled displacement mechanism. In the context of this Buyers Products motor, the synergy of an industry-proven spool valve design with state-of-the-art gerotors forms the foundation of its exceptional performance. The gerotor (GEnerated ROTOR) concept, a positive displacement design, is particularly adept at generating high torque at low speeds, which is a critical requirement for applications such as powering spreader spinner discs.\u003c\/p\u003e\n\u003cp\u003eThe spool valve mechanism effectively controls the direction and flow of hydraulic fluid into and out of the gerotor chambers. As fluid enters, it causes the inner gerotor gear to orbit and rotate within the outer gear, creating a continuous rotational output at the motor shaft.

Its ability to provide a high degree of start-up torque, coupled with the precise mixture of torque and flow rate, ensures that SaltDogg® spreaders maintain optimal performance even under the most adverse conditions. The 4-bolt mount, a defining feature, provides a secure and robust connection to the spreader assembly, minimizing vibration and enhancing overall structural integrity, critical for sustained operation in rugged environments.\u003c\/p\u003e\n\n\u003ch3\u003eIn-Depth Analysis of Key Specifications\u003c\/h3\u003e\n\u003cp\u003eThe detailed specifications provided are not merely numbers; they represent the meticulously engineered performance parameters that define this hydraulic motor’s capabilities and suitability for its intended application:\u003c\/p\u003e\n\n\u003ch4\u003eCompares To: 101-1001-009\u003c\/h4\u003e\n\u003cp\u003eThis cross-reference number signifies that this Buyers Products motor is engineered to meet or exceed the performance and dimensional specifications of a recognized industry standard or original equipment manufacturer (OEM) part.

A displacement of 3.1 cu. in.\/rev indicates a motor well-suited for medium-duty applications where a balance between speed and torque is desired. Higher displacement motors typically provide more torque at lower speeds, while lower displacement motors achieve higher speeds for a given flow rate.

Operating above continuous ratings for extended periods can reduce the motor’s lifespan.\u003c\/li\u003e\n\u003c\/ul\u003e\nThese flow ratings, when combined with the displacement, determine the potential operational speeds of the spinner, allowing for variable spread patterns and distances.\n\n\u003ch4\u003eInput Mount Type: 4 Bolt\u003c\/h4\u003e\n\u003cp\u003eThe 4-bolt input mount is a crucial mechanical interface. It ensures a robust, secure, and precisely aligned connection between the hydraulic motor and the SaltDogg® spreader frame or gearbox. Compared to 2-bolt mounts, a 4-bolt configuration provides enhanced stability, greater resistance to torsional stress, and superior vibration dampening. This is particularly vital in applications involving rotating masses and continuous vibration, safeguarding both the motor and the driven equipment from premature wear and structural fatigue.

This specification indicates that the motor is designed to operate safely with up to 1500 psi of internal case pressure without the need for an external case drain line. A case drain line is typically used to relieve internal leakage back to the reservoir, preventing pressure buildup that could damage shaft seals. The ability to operate without a case drain simplifies hydraulic system plumbing and installation, making it more robust and less prone to leakage points, while still maintaining seal integrity under typical operating conditions for this motor.\u003c\/p\u003e\n\n\u003ch4\u003eMaximum Speed (Continuous): 969 RPM\u003c\/h4\u003e\n\u003ch4\u003eMaximum Speed at Continuous Flow: 969 RPM\u003c\/h4\u003e\n\u003ch4\u003eMaximum Speed at Intermittent Flow: 1130 RPM\u003c\/h4\u003e\n\u003cp\u003eThese specifications define the rotational velocity of the motor shaft.\n\u003c\/p\u003e\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eContinuous Speed (969 RPM):\u003c\/b\u003e The maximum speed at which the motor can operate continuously without exceeding thermal or mechanical stress limits.

It accommodates a standard parallel key, which transmits rotational torque from the motor shaft to the driven component’s hub (e.g., a coupling or the spinner assembly itself). This positive drive mechanism is essential for reliably transferring power without slippage, especially under varying loads and high torque conditions.\u003c\/p\u003e\n\n\u003ch4\u003eShaft Size: 1.00 inches\u003c\/h4\u003e\n\u003cp\u003eThe 1.00-inch diameter straight shaft provides a robust and strong output interface. This size is engineered to withstand the torsional and bending stresses associated with driving a spreader spinner, ensuring reliable power transmission. A straight shaft, as opposed to a splined or tapered shaft, is commonly used with couplings that rely on a keyway and set screw, offering a straightforward and durable connection for many industrial and mobile applications.\u003c\/p\u003e\n\n\u003ch4\u003eShaft Type: Straight\u003c\/h4\u003e\n\u003cp\u003eA straight shaft design, paired with the specified keyway, is a common and highly effective method for transmitting torque. Its simplicity contributes to ease of manufacturing and robust performance. While other shaft types like splined or tapered offer specific advantages in certain scenarios, the straight shaft with keyway is proven reliable for the demands of spreader applications, offering good balance of cost, strength, and ease of coupling.\u003c\/p\u003e\n\n\u003ch4\u003eTorque Rating (Continuous): 650 in-lbs\u003c\/h4\u003e\n\u003ch4\u003eTorque Rating (Intermittent): 720 in-lbs\u003c\/h4\u003e\n\u003cp\u003eTorque is the rotational force produced by the motor, directly responsible for spinning the spreader disc.\n\u003c\/p\u003e\u003cul\u003e\n    \u003cli\u003e\n\u003cb\u003eContinuous Torque (650 in-lbs):\u003c\/b\u003e This is the maximum torque the motor can consistently produce during extended operation.
