Changing Engine Oil and Replacing Oil Filter

IMPORTANT: If using BIODIESEL blends greater than B20, shorten oil change interval to half the recommended service interval or monitor engine oil using OILSCAN to ensure that fuel dilution does not exceed 5%.

OILSCAN™ or OILSCAN PLUS™ is a John Deere sampling program to help you monitor machine performance and identify potential problems before they cause serious damage. OILSCAN™ or OILSCAN PLUS™ kits are available from your John Deere dealer. Oil samples should be taken prior to the oil change. Refer to instructions provided with kit.

   Rocker Arm Cover Oil Filler Opening

   A - Rocker Arm Cover Oil Filler Opening

   Fill engine crankcase with correct John Deere engine oil through rocker arm cover opening (A). (See Diesel Engine Oil — Tier 2 and Stage II Marine Engines in Fuels, Lubricants, and Coolant Section for determining correct engine oil.)

10. IMPORTANT: Immediately after completing any oil change, crank engine for 30 seconds without permitting engine to start. This will help insure adequate lubrication to engine components before engine starts.

    NOTE: Crankcase oil capacity may vary slightly. ALWAYS fill crankcase within crosshatch marks on dipstick. DO NOT overfill.

    Start engine and run to check for possible leaks.

11. Stop engine and check oil level after 10 minutes. Oil level reading should be within crosshatch on dipstick.
