Service jobs and parts

Engine oil and filter change

Engine · every 500 hours or every year

John Deere says the first change is at 100 hours, then every 500 hours or once a year. The 500-hour interval only applies with Plus-50 II oil, a genuine John Deere filter and low-sulphur diesel; otherwise change at 250 hours.

Part	Qty	Notes	Part number
Engine oil	1	15W-40 (10W-30, 5W-40 or 0W-40 in colder weather). Plus-50 II, ≈25–28 L. Aztec Oils match: EMPROTEC EHPD 15W-40	check your handbook
Engine oil filter	1		RE509672

Step-by-step

Warm the engine, park on level ground, lower the linkage, loader and any implement, stop the engine, take the key out and chock the wheels.
Let it stand a few minutes. Hot oil burns, so wear gloves.
Remove the sump plug and let the oil drain fully.
Remove the filter, check the old seal came off, and wipe the filter head clean.
Oil the new filter seal and fit it hand-tight as marked on the filter.
Refit the plug and fill with Plus-50 II to the full mark.
Run the engine for a minute, check for leaks, stop it and recheck the level.

Tools: Drain tray (35 L), Filter wrench, Spanner for sump plug, Funnel, Gloves, Rags

Step-by-step

Watch the display for exhaust filter warnings and let regenerations finish.
If the warning stays on, book DPF replacement or cleaning with a John Deere dealer within 250 hours.
Never work near the exhaust until it has cooled; it runs very hot, especially after a regeneration.

Tools: Dealer service tool

Coolant replacement

Cooling · when needed

Cool-Gard II protects against liner pitting, corrosion and frost but wears out. John Deere's sheet gives the quantity but not the interval, so check your handbook and test the coolant every year.

Part	Qty	Notes	Part number

Repair guides

Hard starting or stalling: fuel filters, water separator and priming (7R and 8R) (Moderate, 1–1.5 hours): Engine cranks but will not start after fuel work, stalls under load, lacks power, or the water-in-fuel light is on.
Exhaust filter or DEF warning, derate or fault codes: owner checks (7R and 8R) (Specialist, 30 minutes of checks; repair by a dealer): Exhaust filter warning, DEF warning, engine reduced power, or repeated regeneration on a Tier 4 7R or 8R.
Weak lift, slow remotes or transmission warning: owner checks (7R and 8R) (Moderate, 1–2 hours): Lift slow or weak, remotes slow, transmission or hydraulic filter warning, noisy hydraulics, milky or dark oil.
Loss of power or black smoke: primary and secondary air filters (7R and 8R) (Easy, 30 minutes): Lack of power, black smoke, air restriction warning, or dust marks inside the intake pipe.
Water in the air brake system or slow air build-up: air dryer cartridge (7R and 8R with air brakes) (Moderate, 1 hour): Moisture comes out of the air tank drain, brakes feel slow to release or the air pressure builds slowly.
