Break-In Checks

IMPORTANT: Initial break-in service interval of a new or rebuilt wet sleeve engine must last at least 100 hours with John Deere Break-In™ Plus oil. The surface mating of rings and liners usually occurs during the first 100 hours.

Maximum service interval is the same as the service interval recommended for your engine. See “Engine Oil and Filter Service Intervals” of Fuels, Lubricants, and Coolant section of this manual.

Engine is ready for normal operation. During first 100 hours of operation:

• Operate engine at heavy loads without reaching sustained maximum load.
• Avoid idling engine longer than 5 minutes. If engine idles longer than 5 minutes, stop engine.
• Closely observe coolant temperature during operation.
• Check air intake hoses and clamps. See “Air, Fuel, Coolant, and Exhaust Maintenance” section.
• Check for fluid leaks.
• Tighten wheel, wheel weight and axle bolts after 3 HOURS, after 10 HOURS, and DAILY for the first week of operation. See “Wheels and Tires Maintenance” section.
