CLEARANCE
Measure the connecting rod bore with the bearings
installed and the bolts tightened to 100 N´m (73 ft.
lbs.) torque.
Record the smaller diameter.
Measure the diameter of the rod journal at the
location shown (Fig. 99). Calculate the average diam-
eter for each side of the journal.
The clearance is the difference between the con-
necting rod bore (smallest diameter) and the average
diameter for each side of the crankshaft journal.
