Engine Break-In Service

RG13719-UN-11NOV04

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 DIESEL 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 DIESEL 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 DIESEL ENGINE BREAK-IN OIL is preferred. See DIESEL ENGINE BREAK-IN OIL, in Fuels, Lubricants, and Coolant Section for other oils allowed.

   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	API 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.

   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.

   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 the normal 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 temperature is below 0°C (32°F), it may be necessary to use cold weather starting aids (See COLD WEATHER OPERATION, later in this section).

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

   Watch Coolant Temperature and Oil Pressure on Panel

   A - Engine Coolant Temperature Gauge

   B - Oil Pressure Gauge

   Watch coolant temperature gauge (A) 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.

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

---




7. Watch oil pressure gauge (B) for pressure within specification.

   Item	Measurement	Specification
   Engine1	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)

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