Hitachi EX300-2 EX300-3 Turbocharger 114400-2961

114400-2961 RHC7 Turbocharger for Hitachi EX300-2 EX300-3 Isuzu 6SD1 Engine

The 114400-2961 RHC7 turbocharger is supplied for Hitachi EX300-2 and EX300-3 excavator repair with Isuzu 6SD1 diesel engine applications. It is used to restore boost pressure, air intake performance and engine combustion stability when the original turbocharger is worn, leaking oil, damaged, noisy or no longer providing normal boost response.

This page should focus on the 114400-2961 turbocharger signal. The old page used a factory-sale style title and kept a full VLS turbocharger catalog list, which mixed many unrelated part numbers, machine models and engine applications into one page. That old structure should be removed to keep the 114400-2961, RHC7, Isuzu 6SD1 and Hitachi EX300-2 / EX300-3 signals clear.

Application Notes for Hitachi EX300-2 and EX300-3

This turbocharger should be checked for Hitachi EX300-2 and EX300-3 excavator applications using Isuzu 6SD1 or 6SD1-TP engine references. Because EX300 series machines can vary by region, engine arrangement and replacement history, the old turbocharger tag and engine plate should be checked before quotation.

Duplicate and Signal Cleanup Notes

The 114400-2961 signal should be concentrated on this product page. Other old turbocharger product pages should not keep 114400-2961 inside a generic VLS catalog table unless that page is specifically about the same part number.

If another Topvelsun page later becomes a stronger main page for 114400-2961, then this page should be merged or redirected. Based on the current check, this page can remain the main 114400-2961 product page after cleanup.

Keep Main Page: /turbocharger/88.html for 114400-2961

Clean From Other Pages: 114400-2961 inside unrelated old turbocharger tables

Old Internal Row to Remove: VLS-D3018 EX300-2/3 114400-2961

New Main Part Signal: 114400-2961 / RHC7 / Isuzu 6SD1 / Hitachi EX300-2 EX300-3

Why the Old Page Needed Correction

The old title used “Factory Sale Turbocharger” instead of a clean part number and application title. The old description also contained a full VLS turbocharger list, which made the page look like a catalog dump rather than a dedicated 114400-2961 product page.

After refurbishment, this page should only focus on 114400-2961, RHC7, Hitachi EX300-2, Hitachi EX300-3 and Isuzu 6SD1 engine applications. Other turbocharger numbers from the old list should be removed and handled on their own product pages.

Old Signal to Remove: Factory Sale Turbocharger EX300-2/3 114400-2961

Old Module to Remove: Advantage

Old List to Remove: VLS-D3003 to VLS-D3037 generic turbocharger table

New Page Direction: Dedicated 114400-2961 RHC7 turbocharger page

Key Checking Points Before Order

Turbochargers should not be confirmed only by excavator model. The same EX300 series machine may have different engine versions, turbocharger specifications or replacement history, so the old turbocharger plate number and engine model should be checked before quotation.

Part Number Check: Confirm 114400-2961 from the old turbocharger tag, supplier record or removed sample.

Check Number Review: If the buyer provides 114400-3140, 114400-2631 or VA290021, confirm it together with engine model and turbo photos before quoting as a replacement.

Engine Check: Confirm whether the engine is Isuzu 6SD1 or 6SD1-TP.

Machine Check: Confirm Hitachi EX300-2 or EX300-3 application if the turbo is ordered by machine model.

Sample Check: Provide photos of the old turbocharger from the compressor side, turbine side, actuator side and nameplate side.

Turbocharger Replacement Notes

Before replacing the 114400-2961 RHC7 turbocharger, the engine air intake system, exhaust manifold, oil feed line, oil return line and air filter condition should be checked. Turbocharger failure can be caused by oil starvation, dirty oil, air restriction, exhaust leakage or foreign object damage.

After installation, the lubrication system should be primed before engine start. The oil line should be clean, the intake pipe should be free from debris, and the engine should be checked for abnormal smoke, oil leakage, boost pressure loss or unusual turbo noise during testing.
