Engine Operation—Break-In Check

P14859
P14859-UN-19NOV07

A - Coolant Temperature Gauge

B - Oil Pressure Indicator

C - Charging Indicator

IMPORTANT: The engine is ready for normal operation. Extra care during the first 100 hours of operation will result in more satisfactory long-term engine performance and life. DO NOT exceed 100 hours of operation with break-in oil.

  1. Warm up engine at slow rpm. Check coolant temperature gauge (A), oil pressure (B) and charging (C) warning indicators.
  2. Operate the engine at heavy loads with minimal idling during the break-in period.

    During the first 20 hours, avoid prolonged periods of engine idling or sustained maximum load operation. If engine will idle longer that 5 minutes, stop the engine.

  3. Check engine oil, coolant, transmission/hydraulic, and mechanical front wheel drive (if equipped) fluid levels frequently. Watch for fluid leaks.

NOTE: Some increase in oil consumption may be expected when low viscosity oils are used. Check oil levels more frequently.

If air temperature is below -10° C (14° F), use an engine block heater.

IMPORTANT: This engine is factory-filled with John Deere ENGINE BREAK-IN OIL.

If the engine has significant operating time at idle, constant speeds, and/or light load usage, or makeup oil is required in the first 100 hour period, a longer break-in period may be required. In these situations, an additional 100 hour break-in period is recommended, using a new change of John Deere Engine BREAK-IN OIL and a new John Deere oil filter.

Check engine oil level more frequently during engine break-in period.

DO NOT add makeup oil until the oil level is BELOW the ADD mark on dipstick. John Deere ENGINE BREAK-IN OIL should be used to make up any oil consumed during the break-in period.

Dipstick Crosshatch Pattern

A - Crosshatch Pattern

DO NOT fill above the crosshatch pattern (A) or the FULL mark, whichever is present. Oil levels anywhere within the crosshatch are considered in the acceptable operating range.

After the first 100 hours (maximum), change engine oil and replace engine oil filter. See CHANGING ENGINE OIL AND REPLACING FILTER in Lubrication and Maintenance/500 Hour/12 Month Section. Fill crankcase with seasonal viscosity grade oil. See DIESEL ENGINE OIL in Fuel, Lubricants and Coolant section.

If John Deere BREAK-IN OIL is not available, see ENGINE BREAK-IN OIL, in Fuels, Lubricants and Coolant Section.
