Replacement Captured Needle Bearing Plate

The replacement captured needle bearing plate (MPN 9-220) is a critical internal component for timing chain tensioning systems in modern engines. This OEM-specification part restores proper bearing support and needle roller alignment within the timing chain assembly, ensuring smooth power transmission from the crankshaft to camshaft. Whether you're performing a complete timing chain overhaul or replacing a worn tensioner assembly, this bearing plate is essential for maintaining precise valve timing and preventing catastrophic engine damage from chain slippage or stretch.

Captured needle bearings operate under extreme pressure and high rotational speeds within the timing chain guide system, and this plate's precision-machined design ensures minimal lateral play while distributing loads evenly across needle roller surfaces. The compact footprint (4.7 × 4.75 inches) and lightweight construction (0.17 lbs) allow seamless integration into existing timing cover assemblies without modification. Proper bearing plate installation directly impacts chain tension control, reduces noise and vibration, and extends the service life of your entire valve train—critical factors in high-performance and stock engine builds alike.

Professional mechanics and dedicated enthusiasts rely on this bearing plate when rebuilding timing systems after detecting chain rattle, worn tensioner components, or performing preventive maintenance on higher-mileage engines. Installation requires careful alignment during timing chain assembly to avoid bearing preload issues and ensure proper needle roller seating. This part is ideal for OEM restoration, performance engine builds, and any application where factory-spec timing chain reliability is non-negotiable.
