10.Tighten connecting rod bearing cap mounting
nuts to specified torque.
11.Ensure that identification numbers for
connecting rod and connecting rod bearing
cap are matched and notches for bearing
shells are on the same side.
12.Check twist and bend of connecting rod by
using new piston pin in connecting rod small
end bush.
13.Measure twist and bend of connecting rod with
feeler gauge with respect to vertical face of the
connecting rod alignment gauge in vertical and
horizontal plane at a distance of 50 mm from
line joining centers of connecting rod small end
and big end bosses.
14.Check connecting rod big end parent bore
dimension.
connecting rod big end parent bore is slightly
more than maximum permissible limits, it is
possible to reclaim the connecting rod
provided the wear is confined only to
connecting rod bearing cap. In such cases the
connecting rod bearing cap mating surface can
be slightly faced. The parent bore should then
be finished on a connecting rod boring
machine.
16.Ensure that the connecting rod big end and
small end axis are parallel to each other within
the specified limits. Centre to centre distance
between connecting rod small end and big end
is maintained within specified limits.
one or more connecting rods are to be
replaced, ensure that difference in weight of
connecting rod in one engine is within
permissible limits.
18.Install new pair of connecting rod bearing shell
according to size of crank pin journal diameter,
making sure that securing lugs of bearing
shells are properly seated in grooves of
connecting rod and its bearing cap.
Note :
Lower and upper bearings are not
interchangeable.
19.Install connecting rod bearing cap with bearing
shell on connecting rod. Tighten connecting
rod bearing cap mtg. nuts to specified torque.
20.Measure connecting rod bearing bore. Record
the readings in the format given in this manual.
connecting rod big end parent bore
dimension is maintained within specified limits,
proper bearing bore dimension is automatically
achieved.
