New Gear Break-In Procedure
Please follow the below guidelines to ensure a proper break-in and long life of your gears.
• Only use high quality gear oils. ECGS recommends Lucas non-synthetic 85W-140
• On initial run, drive lightly for 15 to 20 minutes then stop to allow differential to cool completely for 20 to 25 minutes.
• Avoid towing and heavy acceleration, as well as vary speeds every 5 to 10 minutes while driving on highways.
• Drive conservatively and do not drive more than 50 miles at a time without allowing a cool cycle during the first 500 miles following installation.
• After completing initial break-in, change gear oil at 500 miles. Small metal particles are normal and gear oil will typically be black. Excessive metal in gear oil should be reviewed by a competent differential mechanic to ensure safety of internal parts.
Post gear oil change and initial break-in: Towing.
• First time towing should be limited to light load for no more than 15 miles, then allow differential to cool completely for 20 to 25 minutes.
• Repeat this procedure for first 45 miles of towing for full break-in of gears for towing vehicles.
PREMATURE OVERLOADING AND IMPROPER BREAK-IN WILL CAUSE GEAR OIL BREAKDOWN AND MAY RESULT IN RING AND PINION FAILURE VOIDING THE GEAR WARRANTY!
Q: How Do I Break-In My New Gears
New gear sets MUST be broken in correctly to prevent damage. Not following proper break-in procedures will lead to overloading and overheating the ring and pinion as well as breaking down and ruining the gear oil. Not following proper break-in procedures can be determined during inspection and will void the warranty.
