How to Use LH+RH Transaxle Set 510375601 510375602 Hydro-Gear EZ2200 / EZT2200, Replacement for Husqvarna Craftsman OEM: Complete Guide
Step 1: Initial Setup and Installation
Ensure your mower is on a level surface with the engine turned off and the parking brake engaged. Begin by lifting the mower’s rear end safely with jack stands. Remove the wheels and the original transaxles carefully. The new units bolt directly into the same mounting points. Apply thread-locker to the bolts as recommended in the mower’s service manual.
Step 2: First-Time User Guide
After installation, check the hydraulic oil level according to the manual. Start the engine and let it idle for a minute to allow the transaxles to prime. Slowly move the control levers to verify the forward and reverse functions. Perform a slow test drive in an open area to ensure responsiveness.
Step 3: Core Functions and Daily Use
These transaxles operate smoothly at various speeds. We found that consistent, smooth lever movements provide the best control. For daily use, always warm up the transaxles by driving slowly for a few minutes before engaging in heavy cutting. This circulates the oil and prevents premature wear.
Step 4: Advanced Techniques
For experienced operators, the 215 ft-lb torque allows for aggressive maneuvering on slopes. You can push the machine harder in thick grass without bogging down. Learning the precise control of independent wheel speeds enables you to execute sharp turns without damaging your lawn.
Step 5: Maintenance and Care
Regular maintenance is key to longevity. Check for fluid leaks around the axle seals and input shafts periodically. Keep the exterior clean of grass clippings and debris to prevent overheating. Given that these are sealed units, there is no need to change the internal fluid under normal conditions, but checking the level is a good practice.
Step 6: Troubleshooting Common Issues
If you experience sluggish movement, first check for air in the system by purging the transaxles. This involves raising the rear wheels and cycling the controls. Uneven movement usually points to incorrect tire pressure or a linkage issue. Contact the seller for detailed technical support if problems persist.

Even if only one side is failing, replace both. This ensures balanced performance and prevents the new unit from failing prematurely due to the extra strain from the old, weak unit.
Tip #3: Use High-Quality Hydraulic Oil
If you need to top off or replace the fluid, use only the recommended 20W-50 motor oil or Hydro-Gear specific fluid. Using the wrong oil can cause damage to the internal components.
Tip #4: Invest in a Good Set of Jack Stands
Safety is paramount. A high-quality jack stand set will hold your mower securely during the swap, making the job safer and easier. This is a small investment that pays off.
Tip #5: Inspect and Replace the Wheel Hub Seals
While you have the transaxles out, it is a great time to replace the seals on your wheel hubs. This prevents future leaks and keeps debris out of the bearings.
Tip #6: Consider a Fender Washer Kit
Using a Hydro-Gear 510375601 510375602 worth buying set means you want the best. A fender washer kit can help distribute the load on the mounting bolts and prevent cracking at the mounting holes over time.
