Check Crankshaft Bearing Clearance (With Micrometer Gauge Internal Measuring Device)
WARNING: This page is about a different variant/trim than selected.
- Measurement the crankshaft bearing journal diameter with a micrometer gauge at the measuring points (I) and (II).
- 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:NOTE: Different classes of bearing shells can be used for a crankshaft bearing to reduce bearing clearance. The stronger of the two bearing shells must be inserted in the crankcase.
- Crankshaft bearing bore diameter
- Crankshaft bearing journal diameter
- Crankshaft bearing shell thickness
- Determine the crankshaft bearing clearance.
Calculation formula: average crankshaft bearing bore diameter minus average crankshaft bearing journal diameter minus crankshaft bearing shell thickness from lower crankcase minus crankshaft bearing shell thickness from engine block.
Refer to Engine Mechanical Specifications for the recommended limits.
