Product Details

The Dayco Premium OEM Replacement Balancer line is focused on replacement parts that match the original engine layout and accessory-drive configuration. PB1725N uses a neutral balance design, a steel outer ring, and a serpentine pulley profile to support proper crankshaft damping and belt alignment in vehicles such as the Chrysler Sebring, Dodge Grand Caravan, and Dodge Journey. The PB1725N harmonic balancer is specified without timing marks, hardware, or a woodruff key, so it is important to verify the engine configuration before installation.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Crankshaft vibration from a worn or separated balancer
• Belt tracking issues caused by pulley wear or misalignment
• Accessory drive noise related to a damaged serpentine pulley
• Engine vibration felt at idle or under load
• Fitment problems when replacing the original harmonic balancer on PB1725N applications

Installation Notes

Confirm crank bore, nose diameter, pulley groove count, and overall dimensions before installation. Because hardware and installation instructions are not included, use the correct service procedure and torque specifications for the engine. Verify that the replacement balancer matches the vehicle’s neutral-balance requirement and accessory drive layout before fitting it to a Chrysler Sebring, Dodge Avenger, Dodge Grand Caravan, Dodge Journey, Volkswagen Routan, Chrysler Town & Country, or Chrysler Pacifica.

Quality Assurance

Dayco’s Premium OEM Replacement Balancer line is built for OE-style replacement use in the listed applications. PB1725N is engineered to match the original fitment requirements for the supported Chrysler, Dodge, and Volkswagen models.
