VOE14528378 14528378 Clutch Damper Disc for Volvo Excavator

VOE14528378 Vibration Damper for Volvo Excavator

The VOE14528378 / 14528378 vibration damper is used for Volvo excavator flywheel coupling and hydraulic pump drive system applications. It is also searched as a clutch damper disc, disc damper, coupling disc, vibration damper clutch or flywheel damper disc for Volvo excavator repair.

This page focuses on VOE14528378 as the main part number. Before ordering, the removed damper should be checked by old part number, teeth count, outside diameter, inside diameter, thickness, bolt holes, center hole, mounting face and machine serial number.

Volvo Excavator Application Reference

Common public application references for VOE14528378 include Volvo EC330B, EC330C, EC340D, EC350D, EC350E, EC360B, EC360C, EC380D, EC380E, EC460B, EC460C, EC480D and EC480DHR excavator models.

Some listings also mention Volvo EC360CHR, EC380DHR, EC380EHR, EC460CHR, PL4608, PL4611 and PL4809D references. These should be treated as checking references only because the damper disc configuration can vary by machine serial number, engine arrangement and hydraulic pump drive layout.

Do not select this part by model name alone. The old damper number, teeth count, disc dimensions and physical layout should be checked before shipment.

Part Number and Technical Checking Notes

The main part number for this page is VOE14528378. Other search formats include VOE 14528378 and 14528378.

The 17T and 362/42.5mm figures appear in public supplier references, but they should still be checked against the removed damper disc. To keep this page focused, VOE14528378 should remain the primary search signal.

Vibration Damper Function

The vibration damper is installed in the engine rear drive and hydraulic pump coupling area. It helps transmit torque while reducing torsional vibration and shock load between the engine flywheel side and the driven hydraulic pump system.

When the damper disc is worn, cracked or incorrectly matched, the excavator may develop vibration, coupling noise, unstable pump drive response or repeated coupling damage. Correct selection is important because the teeth count, outside diameter, inside diameter, center hole and mounting layout must match the original system.

How to Identify the Correct VOE14528378 Damper

• Check whether the old part number matches VOE14528378, VOE 14528378 or 14528378.

• Confirm the teeth count before ordering.

• Measure outside diameter and inside diameter of the removed damper disc.

• Compare thickness, center hole, bolt holes and mounting face layout.

• Check the damping structure, friction surface and coupling center condition.

• Confirm Volvo machine model and serial number when the old number is missing or unreadable.

Common Failure Symptoms

• Abnormal vibration from the engine rear side or hydraulic pump coupling area.

• Knocking, rattling or impact noise during engine start, stop or load change.

• Visible cracks, broken damping structure, damaged teeth or worn friction surface.

• Hydraulic pump drive interruption caused by damper or coupling failure.

• Repeated coupling failure caused by misalignment, loose bolts or incorrect replacement part.

• Excessive vibration after replacement caused by wrong teeth count, wrong diameter or incorrect mounting direction.

Troubleshooting Before Replacement

Before replacing the VOE14528378 vibration damper, inspect the complete flywheel coupling and hydraulic pump drive area. Damper failure may be caused by normal wear, but it can also be related to pump misalignment, loose mounting bolts, engine vibration or previous incorrect installation.

• Check coupling hub, flywheel side and hydraulic pump input side for wear or damage.

• Inspect mounting bolts, washers and spacer parts before installing a new damper.

• Check engine mounts and hydraulic pump mounting bracket for looseness or misalignment.

• Inspect flywheel housing and pump drive housing if repeated damper failure occurs.

• Confirm whether the old damper failed from wear, misalignment, overload, loose bolts or wrong replacement part.

Installation and Maintenance Notes

• Compare the old and new damper before installation, including teeth count, OD, ID, thickness and bolt holes.

• Clean the mounting face and remove debris before assembly.

• Replace damaged bolts, washers or spacer parts when required.

• Tighten bolts evenly according to the service procedure to avoid uneven stress.

• Check alignment between engine flywheel side and hydraulic pump drive side before startup.

• After installation, check abnormal vibration, noise and pump drive response during low-load testing.

Information Needed Before Ordering

To reduce wrong orders, please send the old damper number, Volvo machine model, machine serial number, front and rear photos of the old damper, teeth count, outside diameter, inside diameter, thickness, bolt hole photo and any visible marks before quotation.

FAQ

Q: What is VOE14528378?

VOE14528378 is a Volvo vibration damper or clutch damper disc reference used in excavator flywheel coupling and hydraulic pump drive applications.

Q: Is 14528378 the same search format?

Yes. 14528378 is the numeric format, while VOE14528378 and VOE 14528378 are common Volvo-style search formats.

Q: Which Volvo models are common references?

Common checking references include Volvo EC330B, EC330C, EC350D, EC360B, EC380D, EC460B and EC480D. Extended references should be verified by the old damper and machine serial number.

Q: Is this a 17T vibration damper?

Public supplier references commonly describe VOE14528378 as a 17T damper. The teeth count should still be checked against the removed part before ordering.

Q: What should be checked before ordering?

Check the old damper number, teeth count, OD, ID, thickness, center hole, bolt holes, mounting face and Volvo machine serial number. Clear front and rear photos are recommended.
