How to Use 119-5013 1195013 Hydraulic Pump 0R-7662 0R7662 Compatible With Caterpillar CAT 14G 16G MOTOR GRADER: Complete Guide

Step 1: Initial Setup and Installation

Safety First: Park the motor grader on level ground, engage the parking brake, and lower all attachments to the ground. Relieve all hydraulic pressure by moving control levers back and forth after shutting off the engine. Disconnect the battery.

1. Drain Hydraulic Fluid: Place a suitable container under the hydraulic tank and drain the fluid. This minimizes spillage during pump removal.
2. Remove Lines and Mounting Bolts: Carefully label and disconnect the hydraulic suction and pressure lines from the old pump. Support the lines to avoid strain. Remove the mounting bolts securing the pump to the transmission or drive.
3. Swap the Pump: Remove the old pump. Before installing the new 119-5013 pump, check that the mounting surface on the machine is clean and free of debris. Apply a thin film of clean hydraulic oil to the shaft seal. Carefully align the new pump and hand-tighten the mounting bolts before torquing them to the manufacturer’s specification.
4. Reconnect Lines: Reattach the hydraulic lines, ensuring all fittings are clean and tight. Replace any worn hose or fitting seals.

Step 2: First-Time User Guide

Once installed, the “use” is automatic—it’s driven by the machine’s engine. However, first-time startup is critical:

1. Prime the Pump: Fill the hydraulic reservoir to the correct level with the recommended fluid. Loosen the pressure line connection at the pump slightly.
2. Bleed Air: Crank the engine (without starting) for 10-15 seconds to allow the pump to draw fluid and push air out of the loosened fitting. Tighten the fitting once a steady stream of fluid (not foam) appears.
3. Initial Start & Check: Start the engine and let it idle. Immediately check for obvious leaks around the pump and fittings. Operate each hydraulic function slowly and smoothly to cycle fluid through the system and purge remaining air.

Step 3: Core Functions and Daily Use

In daily operation, this pump simply functions as the original did. You should experience normal blade raise/lower, tilt, and circle turn functions. For optimal pump life, always allow the hydraulic system to warm up for a few minutes in cold weather before applying full working loads. Avoid “cycling” controls rapidly to the stops, which creates pressure spikes.

Step 4: Advanced Techniques

For operators looking to maximize efficiency, understanding the pump’s role is key. Smooth, deliberate control inputs allow the pump to maintain steady pressure, reducing wear and heat generation. If you’re running multiple functions simultaneously (e.g., lifting the blade while turning the circle), be aware that the pump is supplying flow to both, which may slightly slow one function—this is normal system behavior, not a pump flaw.

Step 5: Maintenance and Care

The pump itself requires no routine maintenance beyond being part of the overall hydraulic system care. The single most important thing you can do for its longevity is to maintain clean hydraulic fluid. Change fluid and filters at the intervals specified in your CAT 14G/16G manual. Regularly check for leaks, as running a pump low on fluid causes catastrophic damage. For a complete maintenance schedule, refer to our detailed equipment maintenance checklist.

Step 6: Troubleshooting Common Issues

1. No or Slow Hydraulic Function: Check fluid level first. Ensure the pump shaft is rotating (shear key not broken). Verify that the suction line is not clogged or drawing air.
2. Excessive Noise (Whining): This usually indicates cavitation, often caused by a restricted inlet (clogged filter), low fluid level, or the wrong fluid viscosity (too thick in cold weather).
3. External Leakage: Tighten fittings to proper torque. If leaking from the shaft seal, the seal may have been damaged during installation or failed due to age.

If you encounter persistent issues after a proper installation, it may be necessary to consult a technician. Having a reliable source for the part is key, which is why we recommend purchasing from this verified seller.

Expert Tips for Maximum Value

Tip #1: Flush the System

When replacing a failed pump, metal debris often contaminates the entire hydraulic system. Before installing your new 119-5013 pump, consider a full system flush or at minimum, replace the hydraulic filter and clean the suction screen to protect your investment.

Tip #2: Use the Correct Fluid

Always refill with the hydraulic oil specified in your Caterpillar operator’s manual. Using the wrong viscosity or type can affect performance and reduce the lifespan of the pump and other components.

Tip #3: Invest in a Quality Filter

Pair your new pump with a high-efficiency hydraulic filter. Clean fluid is the best thing for pump longevity. Consider keeping a spare filter on hand. You can find compatible filters here alongside the pump.

Tip #4: Break It In Gently

For the first few hours of operation, avoid running the hydraulic system at maximum pressure for extended periods. Vary the loads and functions to allow internal components to seat properly.

Tip #5: Monitor Fluid Temperature

Install a hydraulic temp gauge if your machine doesn’t have one. Consistently high oil temperature (above 180°F / 82°C) is a killer of pumps and indicates a system problem like a stuck relief valve or inadequate cooling.

Tip #6: Keep Records

Note the date and hour meter reading when you install the pump. This helps track its service life and is valuable information for future maintenance planning and resale.

Common Mistakes to Avoid

1. Mistake: Installing the pump without cleaning the mating surface on the machine. → Solution: Thoroughly clean and inspect the mounting pad. Any grit or old gasket material can cause misalignment and premature seal failure.
2. Mistake: Forgetting to prime the pump before starting the engine. → Solution: Always follow the priming procedure outlined in Step 2 of the guide. A dry start can destroy a new pump in seconds.
3. Mistake: Overtightening hydraulic fittings. → Solution: Use a torque wrench. Over-tightening can crack fittings or distort seals, causing leaks. Under-tightening, of course, will also leak.
4. Mistake: Reusing contaminated old hydraulic fluid. → Solution: This is false economy. New fluid and a new filter are cheap insurance for your expensive new pump.
5. Mistake: Ignoring small leaks. → Solution: Address any seepage immediately. A small leak can quickly become a large one, leading to low fluid levels and pump failure.
