Crankshaft Bearing Clearance, Check (Determine Bearing Clearance with Micrometer and Inside Micrometer) Notice: The crankshaft is removed.
Remove, Disconnect Attach crankshaft bearing cap with crankshaft bearing shell to cylinder block - tightening torque 90 Nm / 66 lbf. ft. + 60 ° + 15 ° . The fastening bolts can be reused to check the crankshaft bearing play.
Measure The average crankshaft bearing diameter is determined using an inside micro-meter at points I, II and III and then calculated.
Formula for calculating the average crankshaft bearing diameter: |
I + II + III |
|
3 |
Example: |
|
I |
54.972 mm |
|
II |
54.981 mm |
|
III |
+ 54.984 mm |
|
|
164.937 mm |
÷ 3 = 54.979 mm |
The average crankshaft bearing diameter is 54.979 mm. |
