1876182600 Isuzu 6HK1 Engine Turbocharger for Excavator

The part number 1876182600 is the original turbocharger that matches the 6HK1-TA1 turbocharged diesel engine of ISUZU (Isuzu). This component is a waste gas turbocharged power enhancement core designed specifically for medium to large hydraulic excavators in the 20-30 ton range. Its universal models clearly cover various mainstream brand equipment equipped with 6HK1-TA1 engines, mainly including Hitachi ZX200-3/5G, ZX240-3, ZX330-3, Shengang SK200-8, SK250-8, as well as Sumitomo SH240-5, SH350-5 and other models. The pictures and part numbers you provide are the only accurate basis for ordering genuine original parts, which can effectively avoid compatibility issues caused by model confusion. It is strictly prohibited to use non original or non model turbochargers to avoid engine power imbalance, abnormal fuel consumption, or serious mechanical failures.

This product is an axial flow exhaust gas turbocharger, with a structure identical to the picture you provided: the turbine housing (exhaust side) is made of high-temperature resistant high nickel cast iron, which can withstand continuous exhaust gas high temperatures of ≥ 950 ℃; The compressor housing (intake side) is made of aluminum alloy casting, and the airflow channel has been optimized. The core high-speed rotor assembly adopts a fully floating bearing design, lubricated and cooled by engine oil. The turbocharger integrates a Wastegate actuator (silver cylindrical component in the picture) to precisely control the boost pressure and prevent engine overload. Its typical technical parameters are: boost pressure range of 1.8-2.2 bar, maximum speed of about 100000-120000 revolutions per minute. The model identification of "6HK1-TA1" directly corresponds to the specific variant of the engine, ensuring the best power and emission matching performance.

Installation specification: Before installation, clean engine oil must be injected into the oil inlet of the turbocharger for pre lubrication. During installation, all interface gaskets/sealing rings need to be replaced, and the installation bolts should be tightened in stages according to the diagonal sequence and torque specified in the maintenance manual (usually 25-35 N · m). Daily maintenance: Clean the air filter every 250 working hours, and replace the engine oil and oil filter every 500 hours, which is the key to ensuring the service life of the turbine bearings. Fault diagnosis: If there is a decrease in engine power, continuous blue smoke (burning oil), or abnormal noise from the turbocharger, it is necessary to check whether the intake and exhaust pipelines are leaking, whether the intercooler is blocked, whether the oil supply is normal, and whether the axial/radial clearance of the turbine rotor exceeds the standard.
