Pioneer Cables DA-366 Engine Harmonic Balancer

OE Replacement Harmonic Balancer

Pioneer Cables DA-366 is an OE replacement engine harmonic balancer built to match original design requirements for proper installation and function. It uses high-grade metal and bonded or pressed rubber construction, with precision machining and dynamic balancing for consistent operation in the engine assembly.

Compatible With applications that call for a 169 mm outside diameter, 44.7 mm depth, and 27 mm inside diameter, this serpentine-drive balancer is a direct-fit style replacement for service work on engine cylinder block components. It is a practical choice when replacing a worn balancer on vehicles such as Honda Civic applications that require OE-style dimensions and balance control.

Product Details

Pioneer Cables OE Replacement Balancer line is built around original-equipment dimensions and construction methods, making it a straightforward option for engine repair and maintenance. DA-366 follows the OE design approach so it installs properly and functions as intended, while the bonded rubber element and balanced assembly help maintain smooth crankshaft damping in the harmonic balancer location. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Replacement Reasons

• Visible rubber deterioration or separation in the balancer
• Engine vibration related to crankshaft damping loss
• Wobble, runout, or imbalance at the front of the engine
• Noise from a worn harmonic balancer assembly
• Service replacement during engine front-end repair

Installation Notes

Verify the outside diameter, inside diameter, and depth before installation to confirm OE-style match. Inspect the crankshaft snout, pulley alignment, and serpentine belt routing during service. Bolt and washer are not included, so reuse or source the required fasteners separately if your application calls for them. Confirm vehicle-specific requirements for Honda Civic and other make/model applications before assembly.

Quality Assurance

Pioneer Cables manufactures this harmonic balancer to OE design standards using precision machining and dynamic balancing for consistent performance. The DA-366 is built as a standard replacement part for engine service where original-style fit and balance are required.
