- The oil feeding channel section is also affected by the bushings driving depth compared with the
crankshaft axial clearance of the limiting surface.
N.B.
TO KEEP THE BUSHINGS ON THE CRANKCASE IN SUCH POSITION, DRIVING IS FORCED ON
CAST-IRON RINGS INSERTED IN THE CASTING OF BOTH CRANKCASE HALVES.
- Check the inside diameter of the main bushings
in the three directions indicated in the diagram.
- Repeat the measurements for the other bushing
half. see diagram.
N.B.
DO NOT TAKE THE MEASUREMENT ON THE
TWO HALF-SHELL COUPLING SURFACE
SINCE THE ENDS ARE RELIEVED TO ALLOW
BENDING DURING THE DRIVING OPERATION.
Before assembling, check that the clearance between the engine crankcase bushing and the crankshaft
is within the predetermined limits.
Characteristic
Crankshaft-bushing maximum clearance admitted:
0.08 mm
- The standard bushing diameter after driving is variable on the basis of a coupling selection.
- The crankcase bushing seats are classified into 3 categories while the crankshaft ones, into 2 cate-
gories.
- Bushings are subdivided into 4 categories according to their thickness (see the table).
