OTTO Connecting Rod Nut 1-12239005-1 (1122390051) is a core engine fastener specially designed for Isuzu 6WG1 engine used on Hitachi ZX450-3 excavator. It provides ultra-high and stable clamping force to lock the connecting rod firmly, ensuring stable linkage operation under high-speed engine rotation and heavy-load working conditions.
OTTO EGR Pipe Nut 8-97061401-1 (8970614011) is a dedicated fastener for Isuzu 6HK1 engine on Hitachi ZX330-3 excavator. It provides steady clamping force to secure the EGR pipe joint, avoiding gas leakage caused by high temperature and engine vibration.
OTTO Isuzu Engine Stud 9-04130825-0 (9041308250) is a heavy-duty threaded fastener for Isuzu engines fitted on Hitachi excavators. It delivers uniform clamping tension to connect engine assemblies firmly and prevents joint separation under strong vibration during excavation operations.
OTTO Isuzu Engine Filter 9-81355065-0 (9813550650) is a professional filtration component designed for Isuzu engines and Hitachi excavator equipment. It effectively traps fine impurities, dust and metal particles in engine oil or fuel, purifying circulating fluid and protecting core engine parts from abrasive wear during long-term construction operation.
OTTO Exhaust Pipe Stud 8-98048446-0 (8980484460) is a heavy-duty fastener for Isuzu 4JJ1 engine of Hitachi ZX110-3 excavator. It delivers consistent clamping force to secure the exhaust pipe assembly, avoiding exhaust gas leakage caused by engine vibration during continuous excavation work.
OTTO Oil Pipe Gasket 1-09623462-0 (1096234620) is a precision sealing spare part for Isuzu 4HK1 engine mounted on Hitachi ZX200-3 excavator. It forms a tight seal on engine oil pipe joint to stop lubricating oil leakage and protect the engine lubrication system under continuous working vibration.
The OTTO Exhaust Manifold Stud 8-97307075-2 (8973070752) is a professional fastening component customized for the Isuzu 4JJ1 engine of Hitachi ZX110-3 excavator. It provides stable and uniform locking tension to firmly fix the exhaust manifold, effectively preventing component loosening and exhaust gas leakage caused by long-term engine vibration and high-temperature operation.
OTTO Injector Nozzle Gasket 8-98181540-0 (8981815400) is a precision sealing part for Isuzu 4JJ1 engine on ZX110-3 excavator. It forms a tight seal around the fuel injector nozzle to stop high-pressure fuel leakage and avoid combustion gas blow-by during engine operation.
OTTO Intake Manifold Bolt 0-28650830-0 (0286508300) is a dedicated fastener for Isuzu 6BG1T engine on ZX200 excavator. It offers consistent clamping force to fix the intake manifold firmly, preventing air ingress and unstable air-fuel mixture under engine vibration.
OTTO Engine Assembly 6HK1 for the machine fitted with the Isuzu 6HK1 engine - supplied as a complete engine assembly, ready to fit. It replaces the original engine in one go - block, cylinder head, injection system, manifolds, fan and flywheel housing - so the old engine is lifted out and the new one dropped in. Supplied weight 781 kg. Send us the machine serial and the number on your old unit and we will confirm before dispatch. 3-12 months warranty options.
