John Deere Tractor 6140D

2. Park tractor on level ground and SHUT OFF engine. Remove key.

3. Remove oil drain plug (A) and drain oil.

5. Remove engine oil filter (B).

6. Apply a film of oil on new oil filter gasket and install new filter. Hand-tighten plus 1/2 turn.

8. Add oil to filler (C). (See Diesel Engine Oil in section 85 Fuel, Lubricants and Coolant.)

Change transmission-hydraulic oil and filter

1. Move rockshaft lever full forward to lower hitch all the way down.

3. Replace transmission-hydraulic oil filter. (See procedure in this section.)

5. Remove cap (B) and fill system with oil as specified in Fuels, Lubricants and Coolant section.

6. Check oil level at sight glass (A) after filling.

8. Start engine and operate for five minutes.

1. Stop engine. (See procedure in Operating the Engine section.)

2. Remove battery cover. (See ACCESS BATTERY in this section.)

3. Wipe battery with a damp cloth. Clean and tighten connections, if needed.

4. Install cover and lower hood.

1. Use a battery hydrometer to check specific gravity of electrolyte in each cell. Charge battery if reading is below 1.215. Replace battery if difference between cells is morethan 0.050 or if battery will not charge above 1.225.

2. Always correct specific gravity reading for electrolyte temperature variation. Add 0.004 to the reading obtained in step one for every 10 °F above 80 °F (add 0.007 to the reading for every 10° above 27 C). Subtract at same rate if electrolyte temperature is below 80 °F (27 C). Correct specific gravity of a fully charged battery is 1.265 to 1.280.

3.A battery is considered fully charged when three consecutive hydrometer readings, taken at hourly intervals, show no rise in specific gravity.

Inspect engine air intake filters

A dual element air cleaner is standard. A dirty primary element is indicated when air restriction indicator on instrument panel illuminates. A dirty element can result in loss of power or excessive smoke.

Clean primary element when indicator on instrument panel illuminates or every 250 hours.

Both elements should be replaced at the same time annually, regardless of condition.

2. loosen latch (A) and remove cover (B).

3. Pull out primary filter element (A). Do not use excessive force. If filter does not pull out with ease, move side-to- side to remove safely.

4. Clean primary element by tapping on palm of your hand.

5. Check rubber seal around filter element for cracks and holes. Replace if element shows any imperfections.

2. Check level in coolant reservoir BEFORE starting tractor.

3. If engine is COOL and level is below MIN COLD mark, remove cap and add coolant to reservoir to bring level between MIN and MAX COLD mark.

1. Disconnect wiring harness (A).

2. Connect a small hoses to end of drains (B).
