Checking side clearance
of
the
crankshaft
Atter
assembling
the
crankshaft, tighten
the
main
bearing cap to the specified torque, and move the
crankshaft to one side, placing a dial gauge
on
one
end
of
the
shaft
to
measure thrust clearance.
This measurement can also
be
effected by inserting
the gauge directly into the clearance between the
thrust bearing and crankshaft thrust surface.
Replace
the
th
rust bearing if it
·1s
worn beyond the
limit.
