What’s Included in the Box

Upon unboxing the DJCXYSM hydraulic drive motor, the packaging is industrial and secure, designed to prevent shipping damage. The main unit is typically housed in a custom foam insert within a sturdy cardboard box. The contents are straightforward: you receive the complete hydraulic drive motor assembly itself. It’s important to note that this is usually sold as a standalone unit. You will not typically find installation hardware, hydraulic fluid, or additional gaskets beyond what is pre-installed on the motor. Our first impression was positive; the motor has a solid, weighty feel indicative of robust construction. The machining on the mounting flange and port threads appeared clean and precise, with no visible casting flaws or burrs. The paint finish was even and matched the typical industrial yellow associated with Bobcat compatible parts. Always verify the part number (6690156 or 6674888) stamped or labeled on the unit against your old motor before beginning installation.

How to Use 6690156 6674888 Hydraulic Drive Motor Compatible with Bobcat Track Loader 864 T200 T250 T300 T320: Complete Guide

Step 1: Initial Setup and Installation

Safety First: Park the track loader on a level, solid surface. Engage the parking brake, lower the attachment to the ground, and relieve all hydraulic pressure by cycling the control levers with the engine off. Disconnect the battery. Removal: Thoroughly clean the area around the existing motor. Disconnect the hydraulic hoses (cap them immediately to prevent contamination). Unbolt the motor from the final drive. You may need a hoist or a second person as the motor is heavy. Installation: Transfer any necessary fittings or hardware from the old motor to the new Bobcat 6690156 hydraulic motor. Apply a thin film of clean hydraulic oil to seals. Carefully align and bolt the new motor into place, torquing bolts to manufacturer specifications. Reconnect the hydraulic hoses securely.

Step 2: First-Time User Guide

After installation, the “first use” is about system verification. Before starting the engine, double-check all connections for tightness. Fill the hydraulic reservoir with the correct fluid type and check levels. Start the engine and let it idle. Listen for unusual noises. Slowly operate the machine, checking for smooth track movement in both directions. This initial test will help you gauge if the best hydraulic motor for Bobcat loader is performing correctly from the start.

Step 3: Core Functions and Daily Use

This motor functions automatically as part of the hydraulic drive system. Daily use involves standard machine operation. For optimal lifespan, allow the machine to warm up for a few minutes in cold weather before applying full power. Avoid “jerky” operation of the controls, as this creates pressure spikes. Smooth, deliberate movements are best for the motor’s internal components.

Step 4: Advanced Techniques

For experienced operators, understanding the motor’s role can improve efficiency. When operating in heavy push/pull conditions, avoid stalling the tracks, as this maximizes stress on the motor. If you notice a slight performance difference between left and right tracks (after confirming it’s not a control linkage issue), it could be related to the individual motor’s break-in period, which may settle after several hours of use.

Step 5: Maintenance and Care

Routine maintenance is external. Regularly inspect the motor housing for oil leaks, especially around seal points. Keep the motor and surrounding area clean from mud and debris to aid in cooling and inspection. The most critical maintenance item is ensuring the hydraulic fluid is clean and changed at recommended intervals. Contaminated fluid is the leading cause of premature hydraulic motor failure. For a full maintenance schedule, see our track loader maintenance checklist.

Step 6: Troubleshooting Common Issues

Issue: Track moves slowly or lacks power. Solution: Check primary hydraulic system pressure and fluid level first; the motor is rarely the sole cause. Issue: External oil leak. Solution: Tighten fittings to spec. If leak persists from a shaft seal, the motor may need service. Issue: Loud knocking or grinding noise. Solution: Stop operation immediately. This indicates internal failure. If problems persist, having a reliable source for the part is key. You can always reference the original product listing for support contact information.

Performance & Real-World Testing

Testing Methodology

We installed this motor on a Bobcat T300 with approximately 2,800 hours that had a weak, noisy original drive motor.
