MITSUBISHI L 300 III Platform/Chassis 1994.11-2000.04 2.5 TD (64KW,87PS) MD109736 MD185922 D4BA D4BB D4BH 4D56T 4D56 Cylinder Head Pajero 2.5D Hyundai – OEM MD109736

Product Overview: This complete cylinder head assembly is engineered for the Mitsubishi 4D56, 4D56T and Hyundai D4BA, D4BB, D4BH 2.5-litre diesel engines, the proven powerplants fitted to the L300, Pajero, Canter and Hyundai H-1 and H100 vans. It is supplied fully assembled with valves, guides and seats installed and is machined to original equipment tolerances, offering a reliable replacement for a cracked, warped or valve-damaged original head.

Key Features: The casting is produced from high-grade material and CNC-machined for accurate deck flatness, correct valve seat concentricity and consistent combustion chamber volume. Valve guides and seats are pre-installed and honed for even sealing and balanced compression across all four cylinders, and the cam carrier surfaces are finished for correct bearing clearance. Injector seats and pre-chamber bores are precisely machined to maintain correct diesel combustion, while machined intake and exhaust flanges ensure reliable gasket sealing under continuous load.

Vehicle Compatibility: This head fits Mitsubishi L300 III Platform/Chassis 2.5 TD (1994-2000, 64 kW / 87 PS), Canter V 2.5 (1992-1996) and Hyundai H-1 Van 2.5 TD (2000), H100 Van 2.5 D (1993-2000) and H100 Platform/Chassis (2004 onwards) models equipped with the 4D56 or D4BH engine. Always confirm the engine code and OE reference before ordering.

Specifications: Engine code D4BH / 4D56; displacement 2.5 litres; inline four-cylinder diesel; material cast iron or aluminium; standard size; new condition; complete assembly; 12-month warranty; intended for replacement and repair.

OEM / Reference Numbers: MD109736, MD185926, MD185922, MD139564, MD303750, MD348983, MD351277, MR984455 and 22100-42700. Cross-reference these numbers with the casting identification on the original head to confirm the correct variant.

Applications: Suitable for vans, light trucks, off-road vehicles and commercial fleets, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance where a durable factory-specification diesel head is required.

Benefits / Replacement Information: Installing this assembly restores compression, corrects coolant and combustion leakage caused by cracking or distortion, and avoids the expense and delay of re-machining the original casting. A complete unit ensures matched valve and seat geometry for dependable long-term sealing.

Installation or Fitment Notes: Installation should be carried out by a qualified technician. Verify block deck flatness, fit a new head gasket and new head bolts where specified, and torque in the correct sequence to the manufacturer's figures. Check valve clearances and injection timing after assembly, then pressure test and bleed the cooling system before returning the vehicle to service.
