and the crankcase surface (fig. 59) there is a maxi clearance of:
The axial clearance is measured at the timing cover gaskets and

If the axial clearance of the crankshaft becomes excessive after a
long working period, add adjustment shims to the engine shaft and
camshaft gear until the clearance returns to normal values (fig. 60).
0.2 and 0.3 mm shims are available.
