Detailed Description

Dayco PB1107N is an engine harmonic balancer engineered for OE-style replacement on Nissan compact platforms that use a dual-serpentine pulley layout.

What It Is Used For

• Restoring crankshaft vibration damping on worn or damaged balancers
• Replacing a balancer with cracked or separated outer ring material
• Addressing belt drive issues related to pulley wear or misalignment
• Maintaining timing reference visibility during engine service
• Supporting OE-style repair on Nissan Sentra and Nissan 200SX engines

Installation Notes and Tips

Verify crank bore, nose diameter, pulley groove count, and timing mark orientation before installation. Hardware, installation instructions, and woodruff key are not included. Because this is a harmonic balancer for engine service, confirm the crankshaft snout and pulley alignment are clean and free of damage before mounting the part. Use the vehicle-specific service procedure for torque and timing verification.
