Service jobs and parts
Fuel filter element change
Fuel · every 200 hours or every 6 months
The Perkins 1000 Series handbook says renew the fuel filter element(s) at the first service and then every 200 hours or 6 months, and check the pre-filter for water every day. Perkins warns that the wrong element can damage the injection pump.
| Part | Qty | Notes | Part number |
|---|---|---|---|
| Fuel filter element (CAV, long) | 1 | 112 mm long CAV-type element (also 1896287M91, Perkins 26560602) | 3405419M1 |
Step-by-step
- Stop the engine, take the key out and chock the wheels. Keep naked flames well away.
- Clean the outside of the filter head and bowl thoroughly.
- Drain the filter, remove the element and throw it away with its old seals.
- Fit the new element with new seals.
- Bleed the air out as the handbook describes (the Perkins handbook gives the method for each filter and pump type).
- Start the engine and check for leaks.
Tools: Spanners, Container for fuel, Lint-free rags
Coolant drain and refill
Cooling · every 2 years
The Perkins 1000 Series handbook says renew the antifreeze every two years (or every six months if an inhibitor is used instead of antifreeze).
| Part | Qty | Notes | Part number |
|---|---|---|---|
| Antifreeze with corrosion inhibitor | 1 | About 50/50 with water, ≈17.5 L system | check your handbook |
Step-by-step
- Only work on a cold engine. Turn the radiator or header tank cap slowly to let pressure out.
- Drain the radiator and block into a tray. Dispose of old coolant properly.
- Flush through with clean water, close the drains and refill with a 50/50 mix.
- Run the engine to warm up with the heater on, let it cool and top up.
Tools: Drain tray, Hose, Antifreeze tester
Engine oil and filter change
Engine · when needed
The Perkins 1000 Series handbook schedule has 200-hour/6-month and 400-hour/12-month columns, but the copy used does not show which one the oil change sits in, and the MF handbook was not available. Check your handbook. Perkins says the oil interval also depends on fuel sulphur, while the filter interval does not. Change the filter every time.
| Part | Qty | Notes | Part number |
|---|---|---|---|
| Engine oil | 1 | ≈6.5 L; grade: check your handbook | check your handbook |
| Oil filter (spin-on) | 1 | Perkins number for 1004-series engines; confirm by your engine number | 2654403 |
Step-by-step
- Park on level ground, lower implements to the ground, stop the engine, take the key out and chock the wheels.
- Run the engine to warm the oil, stop it and let it stand a few minutes. Hot oil burns, so wear gloves.
- Remove the sump plug and let the oil drain fully. Refit the plug with a sound washer.
- Unscrew the old filter, check the old seal came off with it, and wipe the head clean.
- Oil the new seal and fit the filter by hand as it says on the filter.
- Fill to the full mark on the dipstick, run the engine, check for leaks, stop and recheck the level.
Tools: Drain tray (10 L), Spanner for sump plug, Filter wrench, Funnel, Rags, Gloves
Air cleaner elements
Engine · when needed
Dust wears the engine fast. Replace the elements when the restriction indicator shows or as your handbook says; the hour figure was not available in the sources used.
| Part | Qty | Notes | Part number |
|---|---|---|---|
| Outer air filter | 1 | For build number prefix AH or AK with a 383 mm air cleaner box | 3901475M1 |
| Inner (safety) air filter | 1 | For build number prefix AH or AK; 3901465M2 also listed | 3901465M1 |
Step-by-step
- Stop the engine and take the key out. Never run the engine with the element out.
- Open the air cleaner housing and take out the outer element. Only remove the inner element when replacing it.
- Wipe the housing with a damp cloth; do not let dirt fall into the intake.
- Fit the new elements and check the seals sit evenly. Check the intake hoses and clips.
- Check your build number prefix and air cleaner box length before buying; there is a serial break.
Tools: Torch, Damp cloth
Transmission and hydraulic oil and filter change
Transmission · when needed
Old oil wears the gearbox, the power shuttle clutches and the hydraulic pump. No source used gives the 4255's interval, oil type or full fill, so check your handbook. Change the filter(s) with the oil every time.
| Part | Qty | Notes | Part number |
|---|---|---|---|
| Transmission/hydraulic oil | 1 | Hydraulic system ≈50 L (TractorData); full fill and type: check your handbook | check your handbook |
| Transmission/hydraulic filter(s) | 1 | 160 mm main element. Agriline also lists spin-on 3595175M1 and tandem pump strainer 3800305M91 for the 4255; check which yours has | 1810694M91 |
Step-by-step
- Park on level ground, lower the linkage and any loader fully, stop the engine, take the key out and chock the wheels.
- With the engine off, work the lift and spool levers to relieve any trapped hydraulic pressure.
- Let the oil cool to warm, not hot, then drain it. Wear gloves.
- Change the filter(s), cleaning around each one first.
- Refit the plugs and fill with the specified oil to the correct level.
- Run the engine, work the hydraulics through their full travel, lower everything, stop and recheck the level.
Tools: Large drain tray (60 L), Spanners, Filter wrench, Pump or funnel
Valve tip clearances
Engine · when needed
Wrong clearances cost power and can burn valves. The Perkins handbook gives inlet 0.20 mm and exhaust 0.45 mm, hot or cold, and says this needs a trained person; the interval was not readable in the copy used, so check your handbook.
| Part | Qty | Notes | Part number |
|---|---|---|---|
| Rocker cover gasket | 1 | For build number prefix AK (also 4223552M91) | 4222997M1 |
Step-by-step
- Stop the engine, take the key out and chock the wheels.
- Remove the rocker cover.
- Turn the engine until the valves you are checking are fully closed.
- Check with a feeler gauge: inlet 0.20 mm (0.008 in), exhaust 0.45 mm (0.018 in).
- Adjust if needed, lock the nut and recheck, then refit the cover with a sound gasket.
Tools: Feeler gauges, Ring spanner and screwdriver, Socket set

Known problems
Air filters change at a build number break
Agriline lists different air filters by build number prefix (AH or AK) and air cleaner box length, so check before buying.
Sources disagree on the engine
TractorData has two 4255 entries: one says Perkins 1004.4TW, the other a 1004T. Check the engine plate before buying engine parts.
Early and late builds differ
Tyre sizes, fuel tanks and dates differ between the 1997–1999 and later 4255 listings, and the AGCO handbook for cab tractors starts at serial K27456 (2001). Use the handbook for your serial number.
Three different gearboxes
The 4255 was sold with a 12x12 power shuttle, a 24x24 power shuttle with power shift, or an 18x6 Speedshift. Oil fills and filters may differ, so know which you have.
Repair guides
- Identify your engine, gearbox and serial number before buying parts (Easy, 30 minutes): Wrong filter, gasket or oil quantity arrives; parts lists give two or more numbers for the same model; the transmission takes a different amount of oil from the book figure.
- Wet brakes weak, noisy or pulling: owner checks (Moderate, 1–2 hours for checks): Long or spongy pedal, tractor pulls when braking with pedals latched, brakes grab or squeal, or the transmission oil looks dark and smells burnt.
- Overheating: water pump and thermostat (Perkins 1004.4T) (Moderate, 2–4 hours): Temperature gauge climbing, coolant loss from the front of the engine, a noisy pump bearing, or the heater staying cold.
- Head gasket replacement (Perkins 1004.4T) (Hard, 8–12 hours): Coolant loss with no visible leak, white smoke, pressure in the cooling system, oil in the coolant, or a misfire with a coolant smell.
- Misfire or air in the fuel: atomisers and bleeding (Perkins 1004.4T) (Moderate, 1–3 hours): Misfire, knocking, black smoke, loss of power, or the engine will not start after running out of fuel or changing a filter.
- Linkage will not lift, lifts slowly or drops (owner checks) (Moderate, 1–2 hours): Linkage will not lift a load it used to, lifts slowly when hot, creeps down with the engine stopped, or hunts up and down.
- PTO slips, will not engage or keeps turning (owner checks) (Moderate, 1–2 hours of checks): PTO slips under load, will not engage, takes a long time to pick up, or keeps turning after being switched off.
- 4WD front axle: swivel (kingpin) and hub bearing play, oil leaks (Hard, 1 hour to check; a day or more per side to rebuild): Front wheel moves when rocked, clunk when changing direction, oil on the inside of a front wheel, uneven tyre wear, or a growl from a front hub.
- Cab air conditioning not cooling (owner checks) (Moderate, 1 hour of checks; regassing by an air-con specialist): Air con blows warm, cools only at speed, the compressor clutch does not click in, the fan is weak, or the cab windows mist.
- Slow cranking, no start or battery not charging: starter and alternator (Moderate, 1–3 hours): Starter clicks but does not turn, slow cranking, battery warning lamp stays on, battery flat every morning, or a whine from the alternator.
