Engine Break-In Service

RG8009-UN-06JAN99

Check Engine Oil

The engine is ready for normal operation. However, 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. This engine is factory-filled with John Deere ENGINE BREAK-IN OIL (SAE 10W-30). Operate the engine at heavy loads with minimal idling during the break-in period.

2. 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.

3. IMPORTANT: DO NOT add makeup oil until the oil level is BELOW the ADD mark on dipstick. John Deere ENGINE BREAK-IN OIL (TY22041) should be used to make up any oil consumed during the break-in period.

   Crosshatch Pattern On Dipstick

   A - Crosshatch Pattern On Dipstick

   Check engine oil level more frequently during engine break-in period. If oil must be added during this period, John Deere ENGINE BREAK-IN OIL is preferred. See ENGINE BREAK-IN OIL, in Fuels, Lubricants, and Coolant Section.

   IMPORTANT: Do not use PLUS-50 oil or engine oils meeting any of the following during the first 100 hours of operation of a new or rebuilt engine:

   	API CI-4 PLUS	ACEA CF
   	API CI-4	ACEA E7
   	API CH-4	ACEA E6
   	API CG-4	ACEA E5
   	API CF-4	ACEA E4
   	API CF-2	ACEA E3

   These oils will not allow the engine to break-in properly.

   IMPORTANT: 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.

   Item	Measurement	Specification
   Engine	Oil Pressure at Full Load Rated Speed With Oil Warmed to 115°C (240°F)	345 ± 103 kPa (3.45 ± 1.03 bar) (50 ± 15 psi)

   Engine Oil Filter

   A - Engine Oil Filter

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

---




5. Before the first 100 hours (maximum), change engine oil and replace engine oil filter (A). (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 Fuels, Lubricants, and Coolant Section.)

   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.

   Watch Coolant Temperature and Oil Pressure On Earlier Panel (Left) or Later Panel (Right)

   A - Engine Oil Pressure Gauge

   B - Engine Coolant Temperature Gauge

   Watch oil pressure gauge (A). Pressure at slow idle should be at least 103 kPa (1.03 bar) (15 psi) once engine is warmed up and shouild rise to at least 241 kPa (2.41 bar) (35 psi) at rated speed under full load.

---




7. Watch coolant temperature gauge (B) closely. If coolant temperature rises above 112°C (234°F), reduce load on engine. Unless temperature drops quickly, stop the engine and determine the cause before resuming operation.

8. NOTE: When the coolant temperature gauge reads approximately 115°C (239°F), the engine will shutdown automatically, if equipped with safety controls.

   Check poly-vee belt for proper alignment and seating in pulley grooves.
