Crankshaft Main Bearings Service
WARNING: This page is about a different car, the 1988 Nissan 300ZX. However, it is still accessible from the selected car via links, so may be relevant.
- Check bearings for scoring or wear. Replace if damaged. If replacing a standard size bearing with a standard oil clearance, replace bearing with one having same number.
- If number cannot be obtained, select bearing by adding numbers on crankshaft and cylinder block together to arrive at numbered bearing needed.
- For example, if cylinder block main bearing bore code number is one and crankshaft journal code number is 2, main bearing code number will be 3. See Fig 1 and CRANKSHAFT MAIN BEARING SPECIFICATIONS chart.
