shaft and then after assembling bearing cap, tight-
en the bolts at the specific torque. Again after dis-
assembling the bearing cap by removing the bolts,
take out the flatted plastic gauge and measure the
width of plastic gauge by means of plastic gauge
measuring scale. This is the oil clearance.
• The oil clearance too can be measured in the same
manner
d. Bearing spread and crush
• Inspection
Check to see that the bearing requires a consider-
able amount of finger pressure at reassembly opera-
tion.
• Crankshaft bearing crush
Install the bearing and cap in the cylinder block,
retighten the bolts to specified torque, unscrew out
one bolt completely, then measure the clearance
between the bearing cap and cylinder block using a
feeler gauge.
• Connecting rod bearing crush
Install the bearing and cap in the connecting rod big
end, retighten the bolts to specified torque, unscrew
out one bolt completely, then measure the clearance
between the bearing cap and connecting rod big end
using a feeler gauge.
e. Crank shaft end play
• Assemble the crankshaft to the cylinder block.
• With a dial gauge, measure crankshaft end play.
