Doosan DH300-5 DA640 Turbocharger 52379706502

52379706502 Turbocharger for Doosan DH300-5 OM442 Engine

The 52379706502 turbocharger is supplied for Doosan DH300-5, DA640 and related OM442 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 52379706502 turbocharger signal. The old product page used a short title with an unverified Holset brand signal 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 52379706502, OM442, DH300-5 and DA640 signals clear.

Application Notes for DH300-5 and DA640

This turbocharger should be checked for Doosan DH300-5, DA640 and related OM442 engine applications. Because OM442 turbochargers can vary by engine version, application, housing type and previous replacement history, the old turbocharger tag and engine plate should be checked before quotation.

Duplicate and Signal Cleanup Notes

The 52379706502 signal should be concentrated on this product page. Based on the current site check, 115.html can remain the main Topvelsun page for 52379706502 after cleanup. Other turbocharger pages should not keep 52379706502 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 52379706502, then one of the two pages should be merged or redirected. At this stage, the safer approach is to keep 115.html as the 52379706502 main page and clean the same signal from unrelated old turbocharger pages.

Why the Old Page Needed Correction

The old title used “Holset” without enough nameplate confirmation, and it described the product only as a general Doosan spare part. The old description also contained a full VLS turbocharger list, which made the page look like a catalog dump rather than a dedicated 52379706502 turbocharger page.

After refurbishment, this page should only focus on 52379706502, OM442 engine, Doosan DH300-5 and DA640 applications. Other turbocharger numbers from the old list should be removed and handled on their own product pages.

Key Checking Points Before Order

Turbochargers should not be confirmed only by machine model. The same DH300-5 or DA640 application may use different turbocharger specifications depending on engine arrangement and replacement history, so the old turbocharger plate number and engine model should be checked before quotation.

Part Number Check: Confirm 52379706502 from the old turbocharger tag, supplier record or removed sample.

Check Number Review: If the buyer provides 53279885607, 53279705607, 53279706502 or X130111350, confirm it together with engine model and turbo photos before quoting as a replacement.

Engine Check: Confirm whether the engine is OM442.

Machine Check: Confirm Doosan DH300-5, DA640 or related 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 52379706502 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.
