- Remove the thermal group (cylinder, head, pis-
ton) as described in the «Thermal group and timing
system chapter».
- Before opening the crankcase, check the crank-
shaft axial clearance.
For this purpose, use a plate (e.g. the special tool)
and a support with special tool comparator.
Specific tooling
020262Y Crankcase splitting plate
020335Y Magnetic mounting for dial gauge
Characteristic
Standard clearance:
0.10 - 0.50 mm
Admissible increase limit after use:
0.60 mm
- Upper clearances are an indication of wear on the surfaces of the crankshaft casing support.
- To carry out an accurate measurement, measure the clearance in both directions between crankcase
and crankshaft.
