Overview — Exhaust Pipe Adapter 8981270441
8981270441 is the exhaust pipe adapter used on HITACHI machines to join the exhaust pipe to the mating flange or component, keeping the exhaust path sealed and correctly aligned. We can supply all the original and replacement part numbers listed below, in stock or available on order — welcome to enquire by part number.
Parts Characteristics
The adapter is machined to the original bore and flange geometry, sized to match the pipe end and the mating component. The material withstands exhaust gas temperature and thermal cycling without distortion, and the sealing face is flat to accept the original gasket or clamp. Fastener holes line up with the mating flange, and the bore keeps the exhaust flow smooth to avoid restriction. As an OEM-spec adapter, it restores the original joint without changes to the exhaust system layout.
Applicable Models & Applications
This exhaust pipe adapter is used on HITACHI engine installations where the exhaust pipe connects to the turbocharger outlet, the silencer or the manifold flange. The family references 8981281760 and 8981338540 cover the same joint duty on adjacent builds. Applications include excavators, wheel loaders and other HITACHI machinery where the exhaust routing must stay sealed under vibration and heat. Confirm the flange pattern, bore size and overall length against the adapter removed from your machine before ordering.
Maintenance & Replacement
Inspect the adapter and its gasket whenever the exhaust system is serviced, looking for cracks, warped flanges and blown gaskets. A leaking exhaust joint allows noise, heat and fumes to escape and can affect back-pressure. When replacing, clean both mating faces, fit a new gasket where specified, and tighten the fasteners evenly to the specified torque. Check that the pipe alignment is correct before final tightening, since a strained joint will fatigue and crack.
