DL06K Interim Tire-4 Diesel Engine Disassembly and Reassembly of Major Components

z Compare the two values obtained
through measurement of connecting
rod bearing inside diameter with the
outside diameters of crankshaft pins
to determine the oil clearance.
(mm)
z If the clearance deviates from the specified range, have the crankshaft journals
and pins ground and install undersize bearings.
c) Oil clearance between crankshaft and bearing (Method 2 : plastic gauge)
z Assemble the crankshaft on the cylinder block and put plastic gauge on the
journal and pin of crankshaft and then after assembling bearing cap, tighten the
bolts at the specific torque.
z Again after disassembling 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.
d) Bearing spread and crush
z Inspection
Check to see that the bearing
requires a considerable amount of
finger pressure at reassembly
operation.
