Check Crankshaft Bearing Clearance (with Micrometer Gauge Internal Measuring Device)
WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
Measurement the crankshaft bearing journal diameter with a micrometer gauge at the measuring points (1, 3) and (2, 4).
- Calculate the average crankshaft bearing journal diameter. Formula: (1. result + 2. result) / 2.
Refer to Engine Mechanical Specifications for the recommended limits.
- Crankshaft bearing clearance is calculated by using:
- Crankshaft bearing bore diameter, refer to Engine Block Overhaul .
- Crankshaft bearing journal diameter
- Crankshaft bearing thickness
NOTE:
Different classes of bearing can be used for a crankshaft bearing to reduce bearing clearance. The stronger of the two bearing must be inserted in the crankshaft bearing cap.
