Engine Break-In

RG10706-UN-11MAY00

Dipstick

A - Dipstick

The engine is ready for normal operation. However, extra care during the break-in period will result in more satisfactory long-term engine performance and life.

1. This engine is factory filled with John Deere Engine Break-In Oil. Operate the engine at heavy loads with minimal idling during the break-in period.

2. IMPORTANT: DO NOT add makeup oil until the oil level is BELOW the ADD mark on dipstick (A). John Deere Engine Break-In Oil (TY22041) should be used to make up any oil consumed during the break-in period.

   If the engine has significant operating time at idle, constant speeds, and/or light load usage, or more than three quarts makeup oil is required in the first 2,500 miles, a longer break-in period is required. In these situations, an additional 2,500 mile break-in period is recommended using a new change of John Deere Engine Break-In Oil and new John Deere oil filter.

   IMPORTANT: DO NOT use regular engine oil during the break-in period of a new engine or engine that has had a major overhaul. This oil will not allow a new or overhauled engine to properly wear during this break-in period.

   Engine Oil Level Dipstick

   A - Crosshatch Areas Showing Proper Oil Level

   DO NOT fill above the top of the RUN range. Oil levels anywhere within the crosshatch area (A) are considered in the acceptable operating range.

   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 Coolants Section.

4. During the first 500 miles, avoid prolonged periods of engine idling or sustained maximum load operation. If engine will idle longer than 5 minutes, stop engine.

5. After the break-in period, change engine oil and replace engine oil filter. Fill crankcase with seasonal viscosity grade oil. (See NATURAL GAS ENGINE OIL in Fuels, Lubricants, and Coolants 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.

6. Watch coolant temperatures closely. If coolant temperature rises above 105°C (221°F), reduce load on engine. Unless temperature drops quickly, stop the engine and determine the cause before resuming operation.
