Oujia Engine Parts — Shijiazhuang Oujia Auto Parts Co., Ltd.

Shijiazhuang Oujia Auto Parts Co., Ltd. — operating internationally under the Oujia Engine brand and accessible at enginegoogle.com — is a specialist Chinese manufacturer and supplier of engine internal components and overhaul parts, with 17 years of production and export experience covering both gasoline and diesel engine applications across passenger vehicles, light commercial vehicles, and heavy-duty truck and bus platforms. Headquartered in Chang'an District, Shijiazhuang City, Hebei Province, Oujia maintains a catalogue of over 2,000 in-stock SKUs spanning the full range of engine internal replacement components — from cylinder blocks and cylinder heads through to pistons and liner kits, crankshafts, camshafts, connecting rods, timing chain and gear kits, full engine gasket sets, and bearing assemblies — covering OEM-equivalent specifications for the Chinese, Japanese, Korean, and European diesel and petrol engine families most widely deployed in Indonesia's commercial vehicle fleet. All products are manufactured to OEM factory standards and backed by a 12–24 month product warranty, with self-branded and OEM-service supply options available for overseas importers and wholesale distributors.

For Indonesia's heavy vehicle aftermarket, Oujia addresses the high-demand segment of engine internal components and overhaul parts for trucks, minibuses, and commercial vehicles — one of the highest-value replacement categories across Indonesia's large and operationally intensive commercial vehicle fleet. Indonesia's truck and heavy vehicle sector is dominated by Japanese medium and heavy-duty truck platforms from Hino, Mitsubishi Fuso, Isuzu, and UD Trucks, alongside a growing Chinese commercial vehicle segment from Sinotruk HOWO, Foton, FAW, Dongfeng, and Shacman — all of which require engine component replacement at major service milestones, following overload or overheating events common in Indonesia's tropical operating environment, or upon engine overhaul after high accumulated mileage on inter-island freight routes, plantation logistics, and construction site haulage. Piston and liner kit renewals, full engine gasket set overhauls, crankshaft and main bearing replacements, timing chain kit renewals, and camshaft replacements are high-value workshop interventions performed regularly by Indonesia's specialist heavy vehicle engine rebuilders, fleet maintenance workshops, and commercial vehicle spare parts importers and distributors operating across Java, Sumatra, Kalimantan, Sulawesi, and the outer islands. Engine internal components sourced from credentialed Chinese OEM-equivalent suppliers represent the dominant price-competitive procurement strategy for Indonesian commercial vehicle spare parts importers and heavy engine rebuild distributors — creating strong structural alignment between Oujia's diesel-capable product scope, overhaul kit supply model, and the active sourcing requirements of Indonesia's truck and heavy vehicle engine parts market.

Products:

Piston & Liner Kit Piston and cylinder liner kit assemblies for heavy-duty diesel engine rebuild applications — covering the combined piston, piston rings, and wet or dry liner set required for a full cylinder overhaul on medium and heavy-duty truck and commercial vehicle engines. Piston and liner kit replacement is the core intervention at engine overhaul events on high-mileage diesel trucks operating in Indonesia's demanding freight and logistics environment, driven by bore wear, piston ring blow-by, oil consumption, and liner scoring from dust ingestion or overheating on long inter-island haulage routes and plantation access roads. Oujia's piston and liner kits cover OEM-equivalent dimensional and material specifications for the Hino, Mitsubishi Fuso, Isuzu, UD Trucks, and Chinese diesel engine families (Sinotruk WD615/WD10, Weichai, Yuchai, Foton Cummins) most widely overhauled in Indonesia's commercial vehicle engine workshop and fleet maintenance sector.

Engine Gasket Set (Full) Complete engine overhaul gasket sets for heavy-duty diesel truck and commercial vehicle engines — encompassing head gasket, oil pan gasket, valve cover gasket, intake and exhaust manifold gaskets, injector seat seals, and all ancillary seals required for a full engine overhaul or head rebuild. Full engine gasket sets are the standard procurement unit for engine rebuild events in Indonesia's heavy vehicle workshop market, sourced in kit form by specialist truck engine rebuilders, fleet maintenance contractors, and commercial vehicle spare parts importers to cover the complete gasket requirement of a single engine overhaul event. Oujia's full gasket sets cover OEM-equivalent specifications for the Japanese and Chinese diesel engine families most widely overhauled in Indonesia's truck and bus aftermarket, including confirmed coverage for Volkswagen/Audi petrol platforms applicable to the light commercial vehicle segment.

Timing Gear / Timing Chain Kit Complete timing gear sets and timing chain kit assemblies — comprising chain or gear train components, tensioners, guides, and idler sprockets — for diesel and petrol engines using gear-driven or chain-driven valve timing systems. Timing component replacement is a scheduled high-mileage maintenance item and a critical repair following timing system noise, chain stretch, or gear wear on high-utilisation commercial vehicle engines operating under sustained load on Indonesia's long-distance freight routes. Oujia's timing kits cover OEM-equivalent specifications for the chain dimensions, gear ratios, tensioner design, and sprocket geometry of the diesel engine families most widely serviced in Indonesia's truck and heavy commercial vehicle aftermarket.

Crankshaft & Main Bearing Set Precision-ground crankshafts and matched main bearing shell sets for heavy-duty diesel engine rebuild applications — providing the core rotating assembly components at the heart of engine overhaul events on medium and heavy-duty trucks and commercial vehicles. Crankshaft and main bearing replacement arises from journal wear, bearing failure following lubrication system faults, or following major engine failure events on high-mileage commercial vehicle engines, and is sourced through Indonesia's specialist heavy engine parts importers and commercial vehicle rebuild component distributors. Oujia's crankshaft range covers standard and reground-equivalent specifications with precision surface finish and dimensional tolerances matched to OEM rebuild standards for the Japanese and Chinese diesel engine families active in Indonesia's commercial vehicle fleet.

Camshaft & Rocker Arm Assembly Replacement camshafts and rocker arm assemblies for heavy-duty diesel engine applications — controlling valve timing, lift, and duration across the engine's intake and exhaust valve train in the overhead valve (OHV) and overhead camshaft (OHC) diesel engine designs used in Indonesia's commercial vehicle fleet. Camshaft and rocker arm replacement arises from lobe wear, journal seizure, or rocker arm pad wear following lubrication system degradation or extended high-load operation, and is sourced through Indonesia's specialist commercial vehicle engine parts distributors and fleet maintenance spare parts channels. Oujia's camshaft and rocker arm range covers the OHV diesel engine families in the Hino, Mitsubishi Fuso, Isuzu, and Chinese commercial vehicle platforms most widely operated and serviced in Indonesia's freight, construction, plantation, and logistics sectors.

Cylinder Head & Cylinder Block Complete cylinder head and cylinder block assemblies for diesel engine rebuild and major repair applications across medium and heavy-duty commercial vehicles — the structural core components of engine overhaul events following head gasket failure, warping from overheating, cylinder head crack damage, or block bore wear on high-utilisation truck engines. Cylinder head replacement is among the highest-value single-component repairs in Indonesia's heavy vehicle workshop sector, with demand driven by the thermal stress and overheating incidents common on trucks operating under overload conditions in Indonesia's tropical climate on mountainous inter-island and plantation haulage routes. Oujia's cylinder head and block range covers OEM-equivalent specifications for the Hino, Mitsubishi Fuso, Isuzu, and Chinese commercial diesel engine families most widely overhauled in Indonesia's heavy vehicle aftermarket.

Connecting Rod (Con Rod) Connecting rod assemblies for heavy-duty diesel engine rebuild applications — linking the piston to the crankshaft and transmitting combustion force through the engine's reciprocating assembly under the high cylinder pressures of turbocharged diesel truck engines. Connecting rod replacement arises from bending, fracture, or bearing journal damage following lubrication failure, over-revving, or hydro-lock events — failure modes encountered on trucks operating without adequate maintenance in Indonesia's demanding freight logistics environment. Oujia's connecting rod range covers standard dimensional specifications for the Japanese and Chinese diesel engine families most widely rebuilt in the Indonesian heavy vehicle aftermarket.
