- If the crankshaft-crankcase axial clearance ex-
ceeds what specified and the crankshaft does not
show any defect, the problem must be due to ei-
ther excessive wear or wrong machining on the
crankcase.
- Check the diameters of both crankshaft bearings
according to the axes and surfaces shown in the
figure. Half-shafts are classified in two categories,
Cat 1 and Cat 2, as shown in the chart below.
CAUTION
THE CRANKSHAFT CAN BE REUSED WHEN THE WIDTH
IS WITHIN THE STANDARD VALUES AND THE SURFACES
SHOW NO SIGNS OF SCORING.
CAUTION
WHILE OPENING THE CRANKCASES AND REMOVING
THE CRANKSHAFT, CHECK THAT THE THREADED
SHAFT ENDS DO NOT INTERFERE WITH THE MAIN BUSH-
INGS. FAILURE TO OBSERVE THIS PRECAUTION CAN
DAMAGE THE MAIN BUSHINGS.
CAUTION
WHEN SEPARATING THE CRANKCASE KEEP THE
CRANKSHAFT IN ONE OF THE CRANKCASE HALF. THE
CRANKSHAFT MIGHT ACCIDENTALLY FALL IF THIS
RULE IS NOT OBSERVED.
NOTE
WHEN MEASURING THE CRANKSHAFT WIDTH, MAKE
SURE THAT THE MEASUREMENTS ARE NOT MODIFIED
BY THE COUPLING SPOKES WITH THE CRANKSHAFT
BEARINGS.
NOTE
TO MEASURE WEAR LIMITS AND COUPLING CLEARAN-
CES, SEE THE SPECIFICATIONS CHAPTER.
