Product Description

Engine Piston ME018277 For Mitsubishi 4D32 3.6L Diesel – 104mm Alfin Steel Piston Assembly

Product Overview

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.

Vehicle Applications

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 applications:

Mitsubishi 4D32T (turbocharged variant)
Mitsubishi 4D34 / 4D34NEW engine applications
Heavy-duty industrial machinery and agricultural equipment
Excavators and construction machinery

Important fitment note: This piston is for the 4D32 and 4D34 engine family with a 104.00 mm bore. It is not for the 4D30, 4D31, 4D33, or other 4D3x variants with different bore sizes. The piston is sold without rings, pin, or circlips - these components must be ordered separately.

Features & Benefits

Tinned Alfin Steel Insert - Superior Ring Groove Wear Resistance

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.

104.00 mm Diameter - Factory Standard Size

Manufactured to exact 104.00 mm outer diameter, matching factory cylinder bore specification for proper piston-to-cylinder clearance.

Precision-Machined Ring Grooves - 2.80 / 2.00 / 4.00 mm

Precisely machined ring grooves with widths of 2.80 mm (top), 2.00 mm (second), and 4.00 mm (oil control) matching factory specifications.

34.00 mm × 84.00 mm Pin Size - Factory Specification

Machined to accept 34.00 mm diameter piston pin with 84.00 mm length, ensuring correct pin-to-bore clearance.

Precision-Engineered Combustion Bowl - 52.00 mm Diameter

52.00 mm combustion bowl precisely machined to factory specification for optimal indirect injection combustion characteristics.

High-Strength Aluminum Alloy Construction

Constructed from high-strength aluminum alloy for optimal strength-to-weight ratio, resisting thermal fatigue and maintaining dimensional stability.

Restores Compression and Power Output

Replaces worn or damaged pistons to restore factory compression, eliminate blow-by, and return engine to designed power output.

Prevents Secondary Engine Damage

Prevents cascading damage to cylinder bore and oil system contamination from cracked or scuffed pistons.

ISO 9001 Certified Manufacturing

Manufactured under ISO 9001 certified quality management systems with batch tracking and material certificates.

Quality Control & Verification

Each batch undergoes comprehensive verification at the OE supplier level:

QC Item	Verification 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 certificate of conformance (COC) with batch material analysis is available for wholesale orders.

Installation & Maintenance Recommendations

⚠️ IMPORTANT: The 4D32 engine uses standard piston rings and pins. Professional installation by a qualified engine builder is strongly recommended.

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:

This is a single piston - order 4 pieces for a complete engine set
Piston rings are not included - order matching ring sets separately
The piston pin and circlips are not included - order separately
Inspect cylinder bore for wear - hone or bore if worn beyond limits
Replace all piston rings when installing new pistons
Lubricate cylinder walls and piston rings with clean engine oil before installation
Use ring compressor for piston installation
Torque connecting rod bolts to factory specification
Refer to Mitsubishi workshop manual for complete procedure

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
