129671-18001 Yanmar Aftermarket Turbocharger 4JH4-HTE 129671-18001 | Sawley's Select Marine Parts

🔧 Product Description

Sawley's Select Marine Parts IHI-Spec RHB52YW MYCZ Aftermarket Turbocharger - Part Number: 129671-18001

A new direct-fit aftermarket marine turbocharger manufactured to replace the IHI RHB52YW MYCZ unit fitted to selected Yanmar 4JH3-TE and 4JH4-HTE diesel engines.

This marine turbocharger uses the IHI 190016 specification and is configured for Yanmar 1.995-litre inline four-cylinder engines. The original Yanmar number, MYCZ identification and housing orientation should be matched before installation because the visually similar MYER turbo fitted to the 4JH4-TE uses a different specification.

🔌 Function

The turbocharger converts exhaust-gas energy into compressor-wheel rotation. The compressor forces additional air into the engine, allowing more fuel to be burned efficiently and restoring the engine's designed power and torque.

Common signs of failure:

• Reduced boost pressure and engine power

• Engine cannot reach its rated operating speed

• Excessive black smoke during acceleration

• Blue exhaust smoke or increased oil consumption

• Whining, siren, scraping or grinding noises

• Oil inside the compressor outlet or intake hose

• Excessive radial or axial shaft movement

• Compressor or turbine wheel contact
