Detailed Description

Dayco PB1400N is engineered as a Premium OEM Replacement Balancer for applications that require a harmonic balancer with the correct bore, width, and pulley configuration. The 154.00 mm outside diameter, 55.60 mm overall width, and 35.59 mm ring width support proper fitment in the listed Isuzu and Honda applications. This part number, PB1400N, is a direct-fit style replacement for engines in the Isuzu Rodeo, Honda Passport, and related Isuzu platforms shown in the fitment data.

The balancer uses a cast iron outer ring, neutral counterweight balance, and timing marks to support crankshaft vibration control and service timing checks. PB1400N is also identified by Dayco as part of its Premium OEM Replacement Balancer line, which focuses on OE-style replacement geometry and application-specific fitment.

What It Is Used For

• Reducing crankshaft vibration in the engine assembly.
• Maintaining accessory drive alignment through the integrated pulley design.
• Providing visible timing reference marks during service.
• Replacing a worn, cracked, or out-of-balance harmonic balancer.
• Restoring proper engine smoothness in listed Isuzu and Honda applications.

Installation Notes and Tips

Verify crank bore, bolt pattern, pulley configuration, and timing mark orientation before installation. This harmonic balancer does not include hardware or installation instructions. Confirm the application notes carefully, especially the 1994 Isuzu Amigo listing with no power steering.
