This check is performed by setting a magnetic-base dial gauge
(2) on the crankshaft (3) as shown in the figure, standard
value is 0.068 to 0.41.
If higher value is found, replace main thrust half bearings of
the second last rear support (1) and repeat the clearance
check between crankshaft pins and main half bearings.

Remove caps from supports.
The backlash between the main bearings and the pins is
found by comparing the width of the calibrated wire (2) at
the narrowest point with the scale on the envelope (1)
containing the calibrated wire.
The numbers on the scale indicate the backlash in mm.
Replace the half bearings and repeat the check if a different
backlash value is found. Once the specified backlash is
obtained, lubricate the main bearings and fit the supports by
tightening the fastening screws as previously described.
