ATP Parts 102148 Engine Harmonic Balancer

OE Replacement Harmonic Balancer

ATP Parts 102148 is an OE Replacement Balancer built to restore crankshaft vibration control and belt alignment in the engine. It is a standard replacement harmonic balancer for serpentine drive applications, including Chrysler Sebring, Dodge Avenger, and Mitsubishi Eclipse fitments from the late 1990s and earlier Mitsubishi/Dodge platforms.

The ATP Parts OE Replacement Balancer line focuses on direct-fit service parts that match original function and mounting style. Part number 102148 is made for engines that use a serpentine belt system and a multi-groove pulley design, helping return the accessory drive to normal operation after balancer wear or failure.

Detailed Description

The harmonic balancer mounts to the crankshaft hub and uses an internal damping layer to reduce engine vibration. Over time, the rubber or fluid element can deteriorate, allowing the outer pulley section to shift and throw the belt system out of alignment. When that happens, the balancer should be replaced to protect the accessory drive and maintain smooth engine operation. ATP Parts 102148 is engineered as a direct OE-style replacement for the original balancer used on select Chrysler, Dodge, and Mitsubishi vehicles, including Chrysler Sebring, Dodge Avenger, and Mitsubishi Eclipse applications.

This part cross-references Pioneer Automotive Industries DA-325 for the same application. Part number 102148 is also referenced in interchange listings for related OE-style service numbers.

What It Helps Fix

• Crankshaft vibration caused by a worn balancer
• Belt misalignment from a shifting outer pulley
• Noise or vibration from a deteriorated damping layer
• Accessory drive issues on serpentine belt systems
• Failure of the original harmonic balancer assembly

Installation Notes and Tips

Verify pulley groove count, outside diameter, and engine application before installation. Confirm the crankshaft hub dimensions match the listed inside diameter and depth specifications. Because this balancer is used on multiple Chrysler Sebring, Dodge Avenger, and Mitsubishi Eclipse configurations, compare the vehicle’s original part and belt layout to the product data before service.
