Product Specifications and Features

Recmar REC129473-18000 is a new aftermarket MY34 marine turbocharger for selected Yanmar 4JH and 4JH2 diesel engines. It replaces Yanmar reference 129473-18000 and cross-references the IHI MY34 / RHB52HW turbo family.

Fitment first: this is a serial-sensitive application. Match the complete engine model, engine serial number and the number on the existing turbocharger before ordering. It must not be selected for a 4JH2-TE or 4JH2-HTE simply because the engine belongs to the 4JH2 family.

Yanmar’s parts catalogue also cross-lists 129473-18000 for certain 4JH2-DTZ installations. For a DTZ application, order only when the existing turbo is positively identified as 129473-18000, MY34 or RHB52HW.

Not a model-only match for: 4JH2-TE or 4JH2-HTE. These engines are catalogued with different turbocharger assemblies.

Installation and ordering checks

  • Confirm the engine serial number against the application table above.
  • Match Yanmar 129473-18000 or the MY34 / RHB52HW identification on the existing turbo.
  • Inspect the mixing elbow for carbon restriction, internal corrosion or water-side failure.
  • Check and clean the turbocharger oil-feed and oil-return systems.
  • Renew the engine oil, oil filter and all disturbed gaskets.
  • Prime the turbocharger with clean engine oil before initial start-up.
  • Correct the cause of the original turbo failure before fitting the replacement.

Installation by a competent marine diesel technician is recommended. If the engine serial or existing turbo number cannot be confirmed, contact us before ordering.

Frequently asked questions

Does this fit the Yanmar 4JH2-TE?

Do not order it for a 4JH2-TE from the model name alone. Yanmar identifies different turbo assemblies for the TE, HTE, DTE and UTE variants. This product requires a 129473-18000 / MY34 / RHB52HW match.

Why is the engine serial number important?

Yanmar changed components during production. The serial boundaries shown above help separate the correct MY34 application from other 4JH and 4JH2 turbochargers.

Are the installation gaskets included?

No. The required gaskets and other installation components must be ordered separately.
