310-9695 Turbocharger for Caterpillar Excavator 315D E315D

310-9695 Turbocharger for Caterpillar 315D E315D C4.2 Engine

The 310-9695 turbocharger is supplied for Caterpillar C4.2 diesel engine applications. It is commonly checked for CAT 315D, E315D, 315D L, 318D, 318D L, 319D and related excavator models. This turbocharger is used to restore boost pressure, improve air intake volume and support stable engine output when the old turbocharger has weak boost, oil leakage, abnormal noise, damaged wheel blades or excessive shaft play.

This replacement turbocharger should be matched by the old turbocharger number, engine model, machine model and removed sample. Since turbocharger housing, flange layout, compressor outlet direction and oil pipe positions can vary by machine version and previous repair history, the old turbocharger tag and sample photos should be checked before order confirmation.

Main Part Number and Ref Cross

The main part number is 310-9695. The no-hyphen format 3109695 may appear in buyer searches, old purchase records or supplier listings. Final matching should still be based on the old turbocharger nameplate, Caterpillar C4.2 engine model and physical housing comparison before shipment.

Part Number: 310-9695

Ref Cross: 3109695

Product Type: Engine Turbocharger

Engine Model: Caterpillar C4.2 diesel engine

Main Application: Caterpillar 315D / E315D excavator

Related Application: 315D L, 318D, 318D L, 319D, 319D L and related C4.2 engine applications, verify by old turbo tag and sample photos

Application Matching Notes

For Caterpillar 315D, E315D, 318D and 319D applications, the safest confirmation method is to check the Caterpillar C4.2 engine model together with the old turbocharger number. Machine model alone is not enough for final matching because the same excavator family can use different turbocharger arrangements depending on serial range, engine configuration and previous replacement history.

Machine Check: Confirm Caterpillar 315D, E315D, 315D L, 318D, 318D L, 319D or the actual equipment model from the buyer.

Engine Check: Confirm Caterpillar C4.2 from the engine plate or service record.

Turbo Tag Check: Check for 310-9695 or 3109695 on the old turbocharger tag or purchase record.

Housing Check: Compare compressor housing, turbine housing, outlet direction, flange type and mounting layout.

Oil Line Check: Confirm oil inlet, oil outlet, pipe position and return line direction.

Photo Check: Provide clear photos of the nameplate side, compressor side, turbine side and mounting side before quotation.

Common Replacement Conditions

A worn 310-9695 turbocharger can cause low boost pressure, black smoke, weak acceleration, oil leakage, abnormal turbo noise, damaged compressor wheel or excessive shaft clearance. Before replacing the turbocharger, the air intake, exhaust and lubrication systems should be checked to reduce the risk of repeat turbo failure.

Low Boost or Black Smoke: Check the air filter, intake pipe, intercooler pipe, compressor wheel condition and boost leakage.

Weak Engine Power: Inspect the compressor wheel, turbine wheel, exhaust leak, boost hose and fuel injection condition.

Oil Leakage: Check the oil feed line, oil return line and crankcase ventilation. A blocked oil return line can cause oil leakage at the turbocharger seal area.

Abnormal Turbo Noise: Check shaft play, bearing wear, wheel contact marks and signs of contaminated oil or foreign object damage.

Inspection Before Installation

Before replacing the 310-9695 turbocharger, inspect the air filter, air intake pipe, exhaust manifold, oil feed line and oil return line. Turbocharger damage is often caused by dirty oil, blocked oil return, air restriction, exhaust leakage or foreign object damage from the intake side.

During installation, add clean engine oil into the turbocharger oil inlet and rotate the compressor wheel by hand before the first engine start. After installation, check for oil leakage, abnormal turbo noise, black smoke, blue smoke, weak boost and unstable engine response during low-speed and working-speed testing.

FAQ

Is 310-9695 the main part number for this product?

Yes. 310-9695 is the main part number for this Caterpillar C4.2 turbocharger direction. The no-hyphen format 3109695 can also be used for inquiry matching.

Is this turbocharger for Caterpillar 315D or E315D?

It can be checked for Caterpillar 315D, E315D and 315D L applications when the engine model, old turbocharger number and sample photos match this 310-9695 direction.

Can this turbocharger be checked for 318D or 319D?

Yes. It can be checked for 318D, 318D L, 319D and 319D L applications when the old turbocharger tag and Caterpillar C4.2 engine information match this product direction.

Why should the old turbocharger tag be checked?

Turbochargers with similar machine applications can still differ by housing, flange, oil line position and outlet direction. The old turbocharger tag and sample photos help confirm the correct replacement before shipment.

What should I provide before ordering?

Please provide the old turbocharger part number, turbo nameplate photo, engine model, equipment model and clear photos of the removed turbocharger.
