Product Description
MD312081 RH Balancer Shaft for Mitsubishi 4D56 2.5L Diesel Engine
The Right Side (RH) Balancer Shaft with OEM number MD312081 is a verified direct-fit replacement for Mitsubishi vehicles equipped with the 4D56 2.5L turbo-diesel inline-4 engine.
Compatible Vehicles
Compatible models include L200 / Triton / Strada (1985-2015), Pajero / Montero / Shogun (1983-2007), Pajero Sport / Challenger / Nativa (1998-2009), L300 / Delica (1986-1994), and Hyundai Satellite (1999-2005).
Product Function
The balancer shaft is a critical component of the engine's NVH (Noise, Vibration, Harshness) reduction system. Positioned on the right side of the cylinder block and driven by the crankshaft via a dedicated belt, it rotates at twice engine speed to counteract the inherent secondary vibrations of an inline-4 diesel engine.
A failing, worn, or incorrectly timed balancer shaft leads to excessive engine vibration, droning noise under acceleration, premature bearing wear, and potential catastrophic engine damage if the drive belt fails.
Part Number: MD312081
Product Name: Balance Shaft
Car Model: Mitsubishi L200 Pajero
Engine Model: Mitsubishi 4D56
Condition: 100% Brand New
Material: High-strength aluminum alloy & precision bearings
Quality Standard: OEM equivalent / ISO quality control
MD312081 RH Balancer Shaft for Mitsubishi 4D56 Engine - Precision-Forged Alloy Steel with Induction-Hardened Journals and Dynamic Balancing 0
Key Features & Benefits
Feature Benefit
Precision-engineered for 4D56 engine Eliminates engine vibration - Specifically calibrated to cancel secondary vibration inherent to 4-cylinder diesel design
Right-hand placement with precision timing marks Simplifies complex timing procedures - Features factory punch marks for exact alignment
Induction-hardened bearing journals Extended service life - HRC 55-60 hardened journals resist wear over hundreds of thousands of kilometers
OE supplier manufacturing quality OEM-level reliability - Manufactured by recognized OE suppliers under IATF 16949 certified systems
Quality Control & Verification
  • Dynamic balancing: Certified balancing machine with runout tolerance within OE specification
  • Material composition: Spectrometer analysis per batch
  • Bearing journal hardness: Rockwell hardness tester - target HRC 55-60
  • Dimensional accuracy: CMM inspection against OE blueprint
  • Crack detection: 100% Dye penetrant inspection per ASTM E1417
⚠️ IMPORTANT: Balancer shaft installation on 4D56 engines requires precision timing and mechanical competence. Professional installation strongly recommended.
Installation Recommendations
Why this part fails (4D56 specific consideration):
On the 4D56 engine, the balancer shaft is driven by a small dedicated belt. Over time, this belt can stretch, wear, or snap. A snapped balancer belt is the #1 cause of catastrophic engine failure on 4D56 engines.
⚠️ CRITICAL: Replace Both Shafts and Drive Belt Simultaneously
Before installation, it is strongly recommended to replace the balancer shafts in pairs (left and right), as the shafts can differ in weight. Additionally, always replace the balancer shaft drive belt at the same time.
Professional Installation Guide
Tools required:
  • Torque wrench (5-50 Nm range)
  • Timing belt tool set for 4D56 engine
  • Crank pulley holding tool
  • Alignment pins/locking tools
  • New balancer drive belt (mandatory)
  • New cam belt (recommended)
Packaging & Supply
  • Individually wrapped in anti-rust coating with protective packaging
  • Packed in foam-lined carton
  • Mounting bolts, bearings, seals, and drive belt sold separately
  • Bulk wholesale: 20 shafts per master carton
  • Shipping dimensions: Approx. 35*10*8 cm, weight approx. 1.8-2.5 kg
Inquiry Information
For RH Balancer Shaft MD312081:
  • Wholesale price for repair shops, parts distributors, and fleets
  • Single unit sample available
  • Bulk order discount & custom packaging
  • Dynamic balancing certificate & QC report upon request
  • Recommended to order LH balancer shaft and drive belt together
Please provide your quantity, destination port, and vehicle specifics for accurate fitment verification.
