It is supplied fully assembled with finish-machined camshaft journals, valve seats, valve guides and combustion chambers, so a cracked, warped or valve-damaged original head can be replaced without additional machining work.\u003c\/p\u003e\u003cp\u003eKey Features: The casting is CNC-machined to original equipment tolerances for accurate deck flatness, correct valve seat concentricity and consistent combustion chamber volume across every cylinder. Valve guides and seats are pre-installed and honed for even sealing and balanced compression, and the aluminum alloy construction with reinforced walls around the valve bridge and fire deck improves durability under sustained thermal and mechanical load. Injector bores, glow plug threads and pre-chamber seats are precision machined to maintain correct fuel atomisation and combustion sealing under diesel cylinder pressures.\u003c\/p\u003e\u003cp\u003eVehicle Compatibility: This assembly is compatible with Nissan CREW (_K30), Nissan CEDRIC (Y30), Nissan CEDRIC (Y32) and Nissan CEDRIC Hardtop (Y31). Because manufacturers frequently revised castings and engine codes within the same model line, always confirm the engine code, casting number and original equipment reference against the component being replaced before ordering.\u003c\/p\u003e\u003cp\u003eSpecifications: Engine code RD28; Inline-6 diesel configuration; material Aluminum Alloy; Standard Size; new condition; supplied as a complete assembly; valvetrain SOHC 12-Valve; 12 Months warranty; place of origin Zhejiang, China; intended for replacement and repair use.\u003c\/p\u003e\u003cp\u003eOEM \/ Reference Numbers: 908501, 1104020V02, 11040G9825, 1104120V01, 1104120V90 and 1104120V91. These references cover several production revisions of the same basic casting, so cross-reference them with the casting marks and part label on the original component to confirm the correct variant.\u003c\/p\u003e\u003cp\u003eApplications: Suitable for Nissan Patrol \/ Terrano \/ Safari \/ Cedric \/ Gloria, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance where a factory-specification component is required. The durable design also suits delivery vans, pickups, minibuses, light trucks and utility vehicles operated under continuous heavy-duty cycles.\u003c\/p\u003e\u003cp\u003eBenefits \/ Replacement Information: Installing this assembly restores lost compression, corrects coolant loss and combustion leakage caused by cracking or distortion, and removes the expense of machining and rebuilding the original head. A correctly specified replacement reduces the risk of repeat failure, helps restore original fuel economy and emissions performance, and returns the engine to reliable service with a predictable service life.\u003c\/p\u003e\u003cp\u003eInstallation or Fitment Notes: Confirm the engine code RD28 and OE number before ordering, and inspect the block deck and piston protrusion for flatness and correct height before fitting. Use new gaskets, head bolts and seals during installation, follow the manufacturer's torque sequence and tightening values, and refill with the correct grade of oil and coolant.\u003c\/p\u003e","brand":"Nanjing Woda Auto Technology Co., Ltd.","offers":[{"title":"Default Title","offer_id":41372132737096,"sku":"1601260965724","price":1224.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/9037\/4728\/files\/Hbd9e5420cd924579a2db16c1b17c23a6U.webp?v=1789954196","url":"https:\/\/autocentreparts.co.nz\/products\/nissan-crew-k30-cedric-y30-cedric-y32-cedric-hardtop-y31-1983-1988-1991-1995-1987-1991-1993-2010-rd28-motor-engine-parts-rd28-cylinder-head-assembly-patrol-rd28t-y30-y31-y32-oem-908501","provider":"Auto Centre Parts","version":"1.0","type":"link"}
