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

Fuel filters (primary and secondary, or kit)

Fuel · every 500 hours or every year

John Deere says replace the fuel filters every 500 hours or once a year, and always both at the same time. The part depends on the engine option code.

Part	Qty	Notes	Part number

Step-by-step

Stop the engine, take the key out and chock the wheels. Keep naked flames away.
Clean around both filters before opening anything.
Drain any water from the primary filter into a container.
Remove the old filters and fit the new ones with clean seals.
Prime the system as your handbook describes. Never crack open the high-pressure pipes on a common-rail engine.
Start the engine and check for leaks.

Tools: Container for fuel, Filter wrench, Gloves, Rags

Fuel water separator filter (where fitted)

John Deere says replace the DPF within 250 hours after the warning lights come on. There is no fixed hour interval.

Part	Qty	Notes	Part number
Diesel particulate filter	1	8235R, 8260R, 8285R: RE541834. 8310R, 8335R, 8360R: RE542183. Dealer service	RE541834

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
Cool-Gard II coolant	1	≈41 L	check your handbook

Step-by-step

Only work on a cold engine; the cooling system is under pressure when hot.
Drain the system from the radiator and engine drain points into a clean tray.
Flush with clean water, refit the drains and refill with the correct Cool-Gard II mix.
Run the engine up to temperature, let it cool and top up the level.

Tools: Drain tray, Hose, Coolant test strips

Known problems

Fuel filter depends on engine option code

Code 3521 takes separate filters; code 3523 takes the kit. Check your engine plate.

DPF differs by model

The 8235R–8285R and the 8310R–8360R take different DPFs.

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.
