Crankshaft Ball Bearing 12x28x8mm for FS-62V - O.S. Engine OS40630000  [OS40630000]

Performance Bearing for FS-62V Crankshafts

This O.S. Engine crankshaft ball bearing is an aftermarket replacement sized for FS-62V engine crankshafts. It acts as a radial support element to maintain crank alignment and reduce rotational friction while the engine runs.

Confirm fitment by measuring the bearing outer diameter and inner bore against your FS-62V crankcase and shaft before pressing the part into service. Correct dimension matching is essential to achieve proper seating and preload characteristics.

Fitment tips: clean all contact surfaces, remove old grease and contaminants, and install the bearing with a press or suitable drift that only contacts the outer race. Never strike the inner race directly. For initial lubrication use a light film of engine-appropriate oil and avoid overfilling the crankcase.

Tuning impact: a fresh crankshaft bearing often reduces vibration, stabilizes idle, and improves throttle response. Inspect bearings routinely during rebuilds and replace when you detect roughness, excess play, or corrosion.
