If you’re looking for a Mitsubishi 4M50 engine for sale, you probably run a truck that earns money, and right now it isn’t earning anything. Maybe the engine lost compression, maybe it cracked a head after overheating, or maybe it’s just worn out after hundreds of thousands of kilometres hauling freight. Every day a Canter sits in the yard costs you, so you want the right engine, fast, and you want it to work first time.
The good news is that the 4M50 is a tough, simple truck diesel, and a lot of the trucks it went into are still working hard around the world. A good replacement engine can give an old Canter or Rosa many more years of work.
We’re NJ Global Auto Parts. We sell used and rebuilt engines and ship them to buyers all over the world. This guide is what we’d tell you if you called us about a Mitsubishi 4M50 engine for sale: the specs, the trucks it fits, how we test, what goes wrong, prices, shipping and fitting advice.
What You Get With a Mitsubishi 4M50 Engine for Sale
The 4M50 is a 4.9 litre, four-cylinder turbo diesel from Mitsubishi Fuso. It’s a big-bore, long-stroke engine built for trucks that carry real weight all day. It sits above the smaller 4M40 and 4M42 in the family and was used mainly in the heavier versions of the Fuso Canter light truck, plus the Rosa bus.
Most 4M50 engines you’ll find are common rail diesels with a turbo and intercooler. Earlier and later versions differ in their fuel systems, emissions equipment and outputs, so the engine number matters when you buy a Mitsubishi 4M50 engine for sale. A later version with exhaust aftertreatment won’t simply swap into an older truck without extra work, and the reverse is true too.
For background on the trucks, the Mitsubishi Fuso Canter page covers the generations and engines used over the years.
Mitsubishi 4M50 Engine for Sale: Full Specifications
These are the figures we get asked about most. Output depends on the exact version, market and emissions level, so treat power and torque as a range.
| Engine code | 4M50 (versions such as 4M50T and 4M50-5AT5 / 6AT5 / 7AT5) |
| Type | Inline 4 cylinder, four-stroke diesel |
| Displacement | 4,899 cc (4.9 L) |
| Bore x stroke | 114 mm x 120 mm |
| Valvetrain | DOHC, 16 valves |
| Fuel system | Direct injection, electronic common rail on most versions |
| Aspiration | Turbocharged and intercooled |
| Power | Roughly 100 kW (136 PS) to 132 kW (180 PS), depending on version |
| Torque | Roughly 370 to 470 Nm, depending on version |
| Block | Cast iron |
| Cooling | Water cooled |
| Emissions | Various levels, later versions with EGR and exhaust aftertreatment |
| Main use | Light and medium trucks, small buses |
The big bore and long stroke are what give the 4M50 its pulling power low down. It isn’t fast, but it will carry a full load up a hill without complaint when it’s healthy.
Which Trucks Use the 4M50
This is the list we work from. It’s a guide, since model names and engine options changed between markets. Send us the chassis number or VIN before you buy a Mitsubishi 4M50 engine for sale from anyone.
- Mitsubishi Fuso Canter FE and FG series, especially the heavier 5 to 8 tonne versions, roughly 2002 onward
- Mitsubishi Fuso Canter 4×4 (FG) in some markets
- Mitsubishi Fuso Rosa small bus, later generation
- Various tippers, tow trucks, refrigerated trucks and box bodies built on those chassis
Trucks were built with different gearboxes, PTO setups and body equipment, so the ancillaries on the engine can vary. When we match a Mitsubishi 4M50 engine for sale to your truck, we check which setup you have so it bolts up properly.
Why Replace the Engine Instead of Rebuilding It
For a working truck, the main question is how fast you can get back to work. Rebuilding in place is possible, but a replacement often wins because:
- Downtime costs money. A replacement engine can be fitted in a day or two. A rebuild can take weeks if the head or block needs machining.
- Cracked heads and blocks. Overheating a hard-working diesel can crack the head or block. At that point a good used or rebuilt engine is usually cheaper.
- Injection parts. Common rail pumps and injectors are expensive. A replacement with a known-good fuel system can make sense.
- Predictable cost. You know what you’ll pay up front, instead of finding more damage halfway through.
For many fleet owners, a tested Mitsubishi 4M50 engine for sale is simply the smarter business decision.
Used, Rebuilt or Long Block
Every Mitsubishi 4M50 engine for sale we offer is one of these. Choose based on budget and how long the truck needs to keep working.
Used engine
Taken from a donor truck, often one written off for cab or chassis damage. It’s the cheapest option and the quickest to get. Our testing is what makes it a safe choice.
Rebuilt engine
Stripped, measured and rebuilt with new liners or rings, bearings, seals and gaskets, with the head checked and machined as needed. It costs more but gives you a fresh start. Good for trucks you plan to keep working for years.
Long block or complete
A long block is the block, head, crank, pistons and cam. A complete engine usually adds the injection system, turbo and ancillaries. We list exactly what’s included in writing.
7 Checks We Make on Every Mitsubishi 4M50 Engine for Sale
Here’s what every engine goes through before we offer it:
- Engine number and donor truck. We confirm the exact version and the truck it came from.
- Compression test on all four cylinders. Diesel compression tells you a lot about rings and valves.
- Blow-by and oil check. Excess blow-by or oil burning points to worn rings or liners.
- Cylinder head check. We look for cracks, signs of overheating and coolant where it shouldn’t be.
- Turbo check. Shaft play, oil leaks and the condition of the compressor wheel.
- Injection system. We check the condition of the injectors and pump and note any leaks or damage.
- External condition. Mounts, housings, sensors and connectors are photographed and listed.
You’ll get real photos of the actual engine and a written summary. If there’s something you should know, we tell you up front.
Common 4M50 Problems
The 4M50 is a strong engine, but hard work takes its toll. If you’re looking at any Mitsubishi 4M50 engine for sale, ask about these.
Injector problems
Common rail injectors can wear or stick, especially with poor-quality fuel or water in the fuel. Symptoms are rough running, smoke, knocking and loss of power.
Overheating and head damage
Overloaded trucks working in heat, with tired radiators, can overheat. That leads to head gasket failure and sometimes cracked heads.
EGR and exhaust aftertreatment
On later versions, EGR valves and coolers can clog with soot, and exhaust filters can block on trucks doing lots of short, slow work. Regular hard runs and proper servicing help.
Turbo wear
Poor oil changes and hot shutdowns wear turbo bearings. Oil leaks and blue smoke are the signs.
Oil leaks
Rear crankshaft seals and various gaskets can leak on high-mileage engines. Not serious on their own, but worth fixing during a swap.
None of these are unusual for a truck diesel. They just mean you want a seller who checks for them. Most of them come down to the same few things: fuel quality, cooling system condition, oil change intervals and how hard the truck has been loaded. An engine that was serviced on time and never overheated is usually a very good buy, even at high mileage.
Signs Your Engine Is Finished
Before you order a Mitsubishi 4M50 engine for sale, be sure you need one. These usually mean the old engine isn’t worth saving:
- Low compression on one or more cylinders
- Heavy blow-by and oil pushing out of the breather
- Coolant in the oil, or oil in the coolant, that isn’t the oil cooler
- A cracked head or block
- A knock from the bottom end
- Very heavy oil consumption with blue smoke
If you see these, put your money into a good engine rather than more diagnosis.
What Comes With the Engine
Every Mitsubishi 4M50 engine for sale we quote comes with a written list of what’s included. It usually covers the long block, and if quoted as complete, the injection pump, injectors, turbo, manifolds and ancillaries. The ECU, radiator, gearbox and wiring usually aren’t included unless we agree otherwise. If you need them, ask and we’ll check the donor truck.
Questions to Ask Any Seller
Whoever you buy from, ask these. A seller offering a Mitsubishi 4M50 engine for sale who won’t answer isn’t worth the risk.
- What’s the engine number, and what truck did it come from?
- Do you have compression figures?
- Can I see photos of this exact engine?
- Is it the same emissions version as mine?
- What’s included, and what isn’t?
- How is it packed, and what’s the freight to me?
We answer all of these before you pay.
4M50 vs 4M51 vs 4M42: Know Which One You Have
This is where a lot of buyers get caught out. Mitsubishi used several related four-cylinder diesels in the Canter and nearby models, and the names are close enough to confuse anyone.
- 4M42 is a 3.0 litre engine used in lighter Canter models. Smaller, lighter, different parts.
- 4M50 is the 4.9 litre engine covered on this page, used in the heavier Canters and Rosa.
- 4M51 is a 5.2 litre engine, mostly older and used in similar trucks. It shares the family look but isn’t the same engine.
If you’re not sure which engine is in your truck, check the stamping on the block or send us the chassis number. It’s the quickest way to avoid ordering the wrong Mitsubishi 4M50 engine for sale. Our 4M51 guide explains that engine in detail if it turns out that’s what you have.
Why the Emissions Version Matters
The 4M50 was sold over a long period and had to meet tighter emissions rules as time went on. That means later engines have extra hardware such as cooled EGR and exhaust aftertreatment, along with different sensors and engine management.
In practice, this means an engine from a newer truck might not run properly in an older one, and the other way round, without swapping the ECU, wiring and exhaust parts too. Some countries also check that the engine matches the truck’s registration and emissions class.
So when you buy a Mitsubishi 4M50 engine for sale, the safest choice is the same version your truck came with. We’ll confirm that from the engine number and chassis details before we quote.
Parts Worth Replacing During the Swap
While the engine is out, some jobs are much cheaper to do than later. We suggest looking at these when you fit your Mitsubishi 4M50 engine for sale:
- Clutch kit. Cover, plate and release bearing. You’ll never have better access.
- Rear crankshaft seal. Cheap part, expensive job if you wait.
- Radiator and hoses. A blocked radiator will cook a good engine.
- Engine mounts. Worn mounts crack brackets and pipes over time.
- Fuel lines and filters. Dirty or damaged lines can damage the injection system.
- Intercooler hoses and clamps. Split hoses cost power and let dirt in.
It adds a little to the job, but it means your new engine isn’t let down by old parts around it.
Working in Hot, Dusty or Remote Areas
Plenty of 4M50 trucks work in tough conditions: construction sites, farms, mines, long rural routes. If that’s your truck, a few extra habits make a big difference. Keep the air filter clean and check it often. Clean the radiator fins, because dust blocks them faster than people think. Carry spare fuel filters, and drain the water separator regularly. A Mitsubishi 4M50 engine for sale that’s looked after like this will cope with hard conditions far better than one that’s ignored.
How Much Does a Mitsubishi 4M50 Engine for Sale Cost?
We don’t post a single price because stock and condition change often. These are what set the price:
- Version and emissions level.
- Condition and test results.
- Used or rebuilt.
- What’s included. Injection system, turbo and ancillaries all add value.
- Freight to your location.
Send us your chassis number and we’ll give you a real price with shipping. The current listing is on our Mitsubishi 4M50 engine for sale product page. You might also like our notes on 4M50 specifications, 4M50 reliability and 4M50 overhaul and rebuild.
Shipping a Mitsubishi 4M50 Engine for Sale Worldwide
We ship every Mitsubishi 4M50 engine for sale worldwide by sea or air. For a heavy truck engine, sea freight is usually the sensible choice. Air is available when a truck is off the road and time matters more than cost.
Each engine is drained, sealed, strapped to a pallet or crated, and wrapped against dust and water. We photograph it before it leaves. You’ll get the documents you need for customs, though import duties depend on your country. The World Customs Organization has general information on how engines are classified for import.
See our shipping policy and refund and returns policy for details.
Fitting Advice for Your Mechanic
- Fresh oil and filter, and prime the oil system before first start.
- New fuel filters and a clean fuel tank. Dirty fuel kills common rail injectors.
- Check the radiator, fan and water pump. Don’t put a good engine into a tired cooling system.
- Check the intercooler and pipes for oil and debris, especially if the old turbo failed.
- Check engine mounts and the clutch.
- Bleed the fuel system properly and check for leaks.
- Run it up, check for codes and do a loaded road test.
That care protects the money you spent on your Mitsubishi 4M50 engine for sale.
Keeping the Engine Working Longer
- Change oil and filters on time, and sooner in dusty or heavy work.
- Use clean fuel and drain the water separator regularly.
- Keep the cooling system in good condition, especially in hot climates.
- Let the engine idle briefly after hard work before shutting off, to protect the turbo.
- Don’t overload the truck.
Look after it and a good Mitsubishi 4M50 engine for sale will keep your truck working for years.
Keep a simple logbook for each truck too: oil changes, filters, coolant work and any faults. It helps your mechanic spot a problem early, and if you ever need another Mitsubishi 4M50 engine for sale, it tells us exactly which version to match.
For Fleet Owners and Workshops
A lot of our 4M50 buyers run fleets or truck workshops. If that’s you, tell us. We can hold engines, send extra photos or videos, and help you plan replacements across several trucks. If you regularly need a Mitsubishi 4M50 engine for sale, we’ll keep an eye out for the versions you run.
What Happens After You Order
Once you’ve paid, we don’t just hand the engine to a forwarder and disappear. We drain it, cap every opening, and strap it down. We take photos of it packed, so you can see exactly how it left us. You’ll get tracking, the bill of lading or air waybill, the commercial invoice and any other papers your customs broker needs.
When it’s on its way, we’re still here. If your mechanic has a question about a sensor, a bracket or which bolts go where, message us. We’ve helped plenty of workshops get a Mitsubishi 4M50 engine for sale fitted and running, and we’d rather answer a question early than have a truck stuck in the yard because of a small misunderstanding.
And when it arrives, check the crate before you sign for it if you can. If anything looks damaged, take photos straight away and let us know. The sooner we hear about a problem, the easier it is to sort out.
