| High Light | Mitsubishi 4D32 engine piston assembly ，3.6L diesel piston with tinned insert ，104mm bore piston for Mitsubishi 4D32 | ||
The engine piston with OEM number ME018277 is a direct factory-spec replacement for the Mitsubishi 4D32 3.6L and 4D34 inline-four diesel engines. This piston transfers combustion force from the cylinder head to the connecting rod and crankshaft.
The 4D32 is a 3,567 cc naturally aspirated diesel engine with a 104.00 mm bore and 105.00 mm stroke, producing approximately 110 PS (108 hp) at 3,500 rpm and 26.0 kg*m of torque at 1,800 rpm. This engine is widely used in Mitsubishi Fuso Canter light-duty trucks and various industrial machinery.
| Part Number: | ME018277 | Product Name: | Piston |

| Car Model: | Mitsubishi | Engine Model: | Mitsubishi 4D32 |
| Condition: | 100% Brand New | Size: | Standard |
| Weight: | Standard | Origin: | China Mainland |
| Main Market: | Middle East, Asia, Africa, South America, North America & Europe | Package: | Neutral Packing Or Custom |
| Material: | High-strength aluminum alloy & precision bearings | Cooling Type: | Engine coolant circulation |
| Installation: | Direct OEM replacement | Quality Standard: | OEM equivalent / ISO quality control |
This Mitsubishi 4D32 engine piston ME018277 directly replaces factory components in:
| Model / Chassis | Engine | Years / Notes |
|---|---|---|
| Canter FE | 4D32 3.6L diesel | 1986-1994 |
| Fuso Fighter | 4D32 / 4D34 | 1988-1995 |
Additional compatible appliions:
Features an Alfin (austenitic cast iron) insert metallurgically bonded into the top ring groove area, providing exceptional wear resistance in high-load, high-temperature conditions.
Manufactured to exact 104.00 mm outer diameter, matching factory cylinder bore specifiion for proper piston-to-cylinder clearance.
Precisely machined ring grooves with widths of 2.80 mm (top), 2.00 mm (second), and 4.00 mm (oil control) matching factory specifiions.
Machined to accept 34.00 mm diameter piston pin with 84.00 mm length, ensuring correct pin-to-bore clearance.
52.00 mm combustion bowl precisely machined to factory specifiion for optimal indirect injection combustion characteristics.
Constructed from high-strength aluminum alloy for optimal strength-to-weight ratio, resisting thermal fatigue and maintaining dimensional stability.
Replaces worn or damaged pistons to restore factory compression, eliminate blow-by, and return engine to designed power output.
Prevents cascading damage to cylinder bore and oil system contamination from cracked or scuffed pistons.
Manufactured under ISO 9001 certified quality management systems with batch tracking and material certifies.
Each batch undergoes comprehensive verifiion at the OE supplier level:
| QC Item | Verifiion Method |
|---|---|
| Piston diameter | Precision micrometer measurement - 104.00 mm ±0.005 mm |
| Ring groove widths | Go/no-go gauge - 2.80 mm, 2.00 mm, 4.00 mm ±0.02 mm |
| Pin bore diameter | Air gauge measurement - 34.00 mm ±0.005 mm |
| Combustion bowl geometry | CMM measurement - verified against 4D32 OE blueprint |
| Alfin insert integrity | X-ray inspection - no voids or delamination |
| Material composition | Spectrographic analysis per batch - aluminum alloy grade confirmed |
| Full dimensional inspection | 100% CMM measurement - all critical dimensions verified |
A certifie of conformance (COC) with batch material analysis is available for wholesale orders.
When to replace this piston (4D32-specific symptoms):
| Symptom | Diagnosis |
|---|---|
| Excessive blow-by - oil mist from oil filler cap | Worn piston rings or cracked ring lands |
| Blue smoke from exhaust | Oil bypassing worn rings into combustion chamber |
| Loss of power under load | Compression loss due to worn or damaged piston |
| Rough idle or uneven running | Uneven compression across cylinders |
| Metallic knocking from engine | Piston scuffing or ring land cracking |
| Metal debris in oil filter | Piston or ring fragments - immediate inspection required |
Critical installation notes:
Maintenance schedule:
| Service Item | Interval |
|---|---|
| Inspect engine for blow-by and oil consumption | At every scheduled service |
| Replace piston rings | When replacing pistons or during full engine rebuild |
| Replace piston | When worn, damaged, or during full engine rebuild |
For full engine rebuilds, the supplier also stocks matching piston ring sets, cylinder liners, connecting rod bearings, and full overhaul gasket kits for the 4D32 engine family.
The Mitsubishi 4D32 engine piston ME018277 is an OEM-specifiion replacement for the 3.6L diesel engine in Fuso Canter FE and Fighter vehicles (1986-1995), as well as industrial and agricultural machinery. The piston features a 104.00 mm diameter, tinned alfin steel insert, ring groove widths of 2.80 / 2.00 / 4.00 mm, and a 34.00 mm × 84.00 mm pin size.
