Upper Crankshaft Bearing (0.25 Oversize)
Why You Need This Part
This upper crankshaft bearing is vital in supporting and enabling smooth rotation of your engine's crankshaft. It maintains proper alignment and reduces friction between moving parts, ensuring your engine runs efficiently and quietly. Bearings with a 0.25 oversize are meant for engines that have had the crankshaft refinished to slightly larger clearances after wear.
How It Works
The bearing fits snugly between the crankshaft and engine blockβs upper surface. It forms a thin oil film that cushions the crankshaft during rotation, minimizing direct metal-to-metal contact and extending engine life. This precise fit helps prevent engine noise and vibration.
What Happens If Broken
If the bearing is damaged or worn out, you may notice knocking sounds, poor engine performance, low oil pressure, or even engine seizure. Neglecting replacement risks severe internal engine damage and costly repairs.
