- Before opening the engine crankcase, it is advisable to check the axial clearance of the crankshaft.
For this purpose, use a plate (e.g. the specific tool) and a support with specific tool dial gauge.
Specific tooling
020262Y Crankcase splitting strip
020335Y Dial gauge magnetic support
Characteristic
Standard clearance:
0.10 ÷ 0.50 mm
Increased limit after use:
0.60 mm
- Higher clearances are signs of wear on the supporting surfaces of the crankshaft on the crankcase.
- To carry out an accurate measurement, measure the clearance in both directions between crankcase
and crankshaft.
- Remove the external and internal transmission covers and the driving and driven pulleys as described
in the «Automatic transmission» chapter.
