For Mitsubishi Pajero and Montero owners requiring uncompromising reliability, the flywheel is a cornerstone of drivetrain integrity. This Cast Iron Flywheel, compatible with part numbers 2355A006, MR446366, and 2355A004, is engineered specifically for the robust 4M41 diesel engine across V60, V70, V80, and V90 series models. It delivers OEM-equivalent performance, ensuring precise clutch engagement and durable operation in both on-road and demanding off-road environments.

High-Grade Material for Superior Performance
Manufactured from premium gray cast iron, this flywheel offers exceptional durability and functional characteristics critical for diesel engine applications. The material provides high tensile strength to withstand the significant torque output of the 4M41 engine, while its excellent thermal stability resists warping and heat spotting caused by clutch friction. Furthermore, cast iron's inherent vibration-damping properties contribute to smoother engine operation, reduced gear noise, and enhanced driving comfort, which is essential for a vehicle known for its refinement and capability.

Precision-Controlled Production Process
The manufacturing of this component utilizes advanced sand casting techniques to create a dense, homogeneous structure free from internal defects. This foundational quality is followed by precision CNC machining on all critical surfaces. Operations include turning the friction surface to ensure perfect flatness and machining the mounting flange for exact concentricity with the crankshaft. The gear ring is meticulously fitted to guarantee flawless starter motor engagement. Finally, each flywheel undergoes dynamic balancing, a critical step to eliminate vibrations that can cause premature wear on the crankshaft and transmission bearings.

Direct Fitment for Trusted Reliability
This flywheel is a direct replacement for the specified OEM part numbers, designed for a perfect fit within the 4M41 powertrain. It is an essential component during a clutch system overhaul, ensuring optimal power transfer from the engine to the transmission. A high-quality flywheel is vital for preventing clutch slippage, chatter, and difficult gear shifts, thereby restoring the vehicle's original driving dynamics and reliability. Its robust construction makes it an ideal choice for enthusiasts and professionals servicing these iconic Mitsubishi SUVs for continued adventure and daily use.

Why are we called OEM experts in Exhaust Manifolds
We develop over 100 different types of exhaust manifolds every year
Dandong Pengxin  Production Process for Exhaust Manifold
Drawing Preparation: The Foundation of Precision,3D Scanning & Drafting: Our professional engineers use advanced scanners to convert samples into 2D/3D drawings (7–10 days).
Pattern & Sample Development: Where Time Invested Pays Off
Complexity: Exhaust manifolds often require 3–5 sets of metal patterns (vs. 1 set for simpler castings).Lead Time: 35–40 days for multi-cavity patterns; 25–30 days for simpler designs.
Initial Orders & Batch Production: Scaling Responsibly
Machine Allocation: One manifold order may occupy 2–3 molding machines. Our 16-machine facility prioritizes urgent orders and collaborates with partner foundries for auxiliary cores.
How Investors Can Mitigate Delays
Allocate 8–12 weeks for pattern/sample development. Compressing this risks quality failures. First batches take 20–30% longer due to process fine-tuning. Post-approval, lead times stabilize.

Why Choose Us

How did Dandong Pengxin Become a Top Manufacturer of Exhaust Manifold

To become a world-leading exhaust manifold producer, Dandong Pengxin Machinery introduced in advanced manufacturing technologies, material innovation, quality control, and supply chain efficiency. Below are the key strategies to achieve this goal.
1.Advanced Casting Technologies (1) High-Precision Casting Processes Resin-Coated Sand Casting (Main production materials are gray cast iron and ductile iron） Ensures thin-wall, complex geometries with excellent surface finish (Ra 6.3–12.5 μm). Ideal for high-performance exhaust manifolds with tight tolerances.
(2)Investment Casting(Main production materials are 316 Stainless Steel and Heat-resistant steel)
Used for premium turbine housings and racing exhaust components,especially for some freight trucks in the United States.
(3)Gravity Casting for Aluminum Manifolds
Lightweight solutions for hybrid/electric vehicle exhaust systems,Gravity casting is the preferred method for mass-producing exhaust manifolds, involving melting metals like cast iron or aluminum and pouring the molten material into preheated steel molds solely by gravitational force. The process naturally fills mold cavities without external pressure, though some advanced variants may apply minimal supplemental pressure (0.2-0.5 bar) for complex geometries. This cost-effective method yields components with uniform 3-6mm wall thicknesses and smooth surfaces, offering superior metallurgical integrity and higher production rates than sand casting, making it ideal for durable exhaust systems requiring consistent quality in high volumes.
2.Quality & Certification Standards ISO 9001/TS 16949 (IATF 16949) → Automotive quality compliance. Leak & Pressure Testing → Ensures 100% gas-tight manifolds. Thermal Cycling Tests → Simulates 10+ years of thermal fatigue. 3D Scanning & CMM Inspection → Validates dimensional accuracy (±0.1mm).
