It is offered as a fully assembled replacement unit with machined camshaft bearing bores, pre-installed valve guides and seats, and finished combustion chambers, making it suitable for an in-frame overhaul or a full engine rebuild.\u003c\/p\u003e\u003cp\u003eKey Features: The casting is produced from high-grade material and CNC-machined to original equipment dimensions, holding deck flatness, valve seat concentricity and injector bore alignment. Valve guides and seats are installed and honed to deliver even sealing and balanced compression across all cylinders, and the pre-chamber and injector seats are precisely machined to maintain correct fuel atomisation. Thickened casting sections around the valve bridge and the fire deck improve resistance to thermal cracking under continuous heavy-duty diesel operation.\u003c\/p\u003e\u003cp\u003eVehicle Compatibility: This head fits Mitsubishi Fuso applications equipped with the 4D34 engine, including light and medium trucks and derived bus chassis produced between 1990 and 2000. Because the 4D34 was used in several configurations, confirm the engine code, casting number and OE reference against the original component before ordering.\u003c\/p\u003e\u003cp\u003eSpecifications: Engine code 4D34; displacement approximately 3.9 litres; inline four-cylinder diesel; material cast iron or aluminium; standard size; new condition; complete assembly; 12-month warranty; designed for replacement and repair.\u003c\/p\u003e\u003cp\u003eOEM \/ Reference Numbers: ME997711, ME990196 and ME997799. Cross-reference these numbers with the identification marks on the original cylinder head to ensure the correct specification is supplied.\u003c\/p\u003e\u003cp\u003eApplications: Ideal for commercial truck fleets, buses, delivery vehicles and industrial equipment powered by the 4D34, as well as workshop overhauls, engine rebuilds and preventive maintenance programmes requiring a durable factory-specification cylinder head.\u003c\/p\u003e\u003cp\u003eBenefits \/ Replacement Information: Installing this assembly restores compression, corrects coolant and combustion gas leakage associated with cracks or distortion, and eliminates the cost and lead time of individually reconditioning valves, guides and seats. A complete unit keeps commercial vehicles productive by reducing workshop downtime.\u003c\/p\u003e\u003cp\u003eInstallation or Fitment Notes: Installation should be performed by a qualified diesel technician. Clean and verify block deck flatness, use new head bolts, gaskets and seals, and torque in the manufacturer's specified sequence and stages. Replace coolant, thermostats and any worn timing components, check valve clearances and injector sealing, then run the engine, re-torque where specified and confirm no leaks before returning the vehicle to service.\u003c\/p\u003e","brand":"Nanjing Woda Auto Technology Co., Ltd.","offers":[{"title":"Default Title","offer_id":41372116353096,"sku":"1601269717783","price":420.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/9037\/4728\/files\/H794001fec9fb4f078a1258206d9ff1d7n.webp?v=1789953466","url":"https:\/\/autocentreparts.co.nz\/products\/mitsubishi-4dqe-1990-2000-complete-4d34-cylinder-head-oem-me997799-mitsubishi-fuso-oem-me997711","provider":"Auto Centre Parts","version":"1.0","type":"link"}
