CAT 235 D25D D30D Turbocharger 7C7582

7C7582 / 7C-7582 Turbocharger for Caterpillar 3306 Engine

The 7C7582 / 7C-7582 turbocharger is supplied for Caterpillar 3306 and 3306B diesel engine repair. It is used to restore engine boost pressure, air intake performance and stable combustion when the original turbocharger is worn, leaking oil, damaged, noisy or no longer providing normal boost response.

This page was previously shown as “High Quality E3306 Turbocharger FOR COMPRESSOR” without a clear part number. Based on the 3306 industrial engine direction and S4DS turbocharger references, the page should be rebuilt around 7C7582 / 7C-7582 instead of keeping the old vague VLS-D3012 signal.

Part Number and Engine Application

The main part number for this page is 7C7582 / 7C-7582. The numbers 8N-7320 and 0R-5805 can be used as matching references for related Caterpillar 3306 / 3306B S4DS turbocharger inquiries. The numbers 196552 and 313272 may also appear in supplier or turbocharger records, but final matching should still be confirmed by the old turbo nameplate and sample photos before shipment.

Application Notes for CAT 3306 and 3306B Engine

This turbocharger should be checked for Caterpillar machines and industrial equipment using 3306 or 3306B engine references. Common inquiry applications may include CAT 235, D25D, D30D, D300D and D350D. If the buyer describes the application as a compressor package, the old turbo nameplate, connection layout and engine plate should be checked before quotation.

Why the Old Page Needed Correction

The old page used “E3306” and “FOR COMPRESSOR” as the main visible signals, but it did not provide a real part number. It also kept an old generic turbocharger list with unrelated machine models and engine references. This makes the page weak for search engines and confusing for buyers.

After refurbishment, the page should focus on 7C7582 / 7C-7582, Caterpillar 3306 / 3306B, S4DS turbocharger and related CAT 235 / D25D / D30D / D300D / D350D applications. VLS-D3012 should not be used as an OEM part number.

Key Checking Points Before Order

Turbochargers should not be confirmed only by a machine model or old catalog line. The same Caterpillar 3306 engine family can appear in different machines and industrial applications, so the old turbocharger plate number and connection layout should be checked before quotation.

Part Number Check: Confirm 7C7582 or 7C-7582 from the old turbocharger plate, supplier record or removed sample.

Cross Number Check: If the buyer provides 8N-7320, 0R-5805, 196552 or 313272, confirm it together with engine model and turbo photos.

Engine Check: Confirm whether the engine is Caterpillar 3306 or 3306B.

Application Check: Confirm CAT 235, D25D, D30D, D300D, D350D or industrial 3306 engine application.

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 7C7582 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.
