Break-In Check—First 100 Hours

NOTE: The initial break-in service interval of a new or rebuilt wet sleeve engine with Break-In Plus must go at least 100 hours to assure the surface mating of the rings and liners has had an opportunity to occur. The 100 hour minimum applies to all new or rebuilt engines. The maximum service interval is the same as the service interval recommendations listed in Engine Oil and Filter Service Intervals for your engine. To confirm which engine your tractor is equipped with, see Identification Numbers Section - Record Engine Serial Number in this Operator's Manual.

For subsequent oil changes, see Engine Oil and Filter Service Intervals for your engine located in the Fuels, Lubricants, and Coolant Section of this Operator's Manual.

Engine is ready for normal operation.

IMPORTANT: John Deere Break-in Oil must be added if oil level is below the ADD mark on dipstick. Do NOT fill above the crosshatch pattern or the FULL mark.

During the first 100 HOURS observe the following:

• Tighten wheel and axle bolts after 3 hours and after 10 hours of operation, or every 2 hours under severe conditions. Continue to tighten to specified torque daily during the first week of operation. (See Wheels, Tires, and Treads Section.)
• Perform daily or 10 hour service. (See Maintenance and Service Intervals Section.)
• Check engine oil level and coolant level more frequently.
• Check transmission/hydraulic oil level.

• Avoid prolonged periods of engine idling or sustained maximum load operation. If engine will idle longer than 5 minutes, stop engine.
• Watch coolant temperature closely.
• Check engine air intake system hoses and hose clamps for tightness.
• Check for coolant or hydraulic leaks.
