Crankshaft Bearing Play, Check (Determine Bearing
Play with Plastigage)
Inspect
Bearing play – bearing cover removed.
Caution
Clean crankshaft journal and crankshaft bearing shell and
lubricate slightly so that thread does not tear when bearing cap is
removed. Do not turn crankshaft.
Measure
|
With "Plastigage" (deformable plastic thread).
Cut strip to width of bearing and place axially between
crankshaft bearing journal and bearing shell (arrow). Install
bearing cap to torque – tightening torque 90 Nm / 66 lbf. ft.
+ 60° + 15°.
Note: The bolts can
be reused for checking crankshaft bearing play.

 Remove
|
Remove bearing cover.
Measure
Compare width of flattened plastic thread (arrow) with measuring
scale.
"Plastigage" is available for various measuring ranges.
Permissible crankshaft bearing play: 0.028 – 0.057 mm.
Note: When reading
the value, do not confuse millimetres with inches on the measuring
scale.
