16.Check connecting rod big end parent bore di-

mension.

connecting rod big end parent bore is slightly

more than maximum permissible limits, it is pos-

sible 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 connect-

ing rod boring machine.

18.Ensure that the connecting rod big end and small

end axis are parallel to each other within the

specified limits. Centre to centre distance be-

tween connecting rod small end and big end is

maintained within specified limits.

one or more connecting rods are to be re-

placed, ensure that difference in weight of

connecting rod in one engine is within permissible

limits.

20.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.

! CAUTION

Lower and upper bearings are not interchangeable.

21.Install connecting rod bearing cap with bearing

shell on connecting rod. Tighten connecting rod

bearing cap mtg. nuts to specified torque

22.Measure connecting rod bearing bore. Record the

readings in the format given in this manual.

23. If connecting rod big end parent bore dimension

is maintained within specified limits, proper bear-

ing bore dimension is automatically achieved.

24.However, it must be physically measured and

confirmed. Measure pretension of connecting rod

bearing shell with a feeler gauge after loosening

connecting rod bearing cap mounting nut on op-

posite side of bearing shell lug.

Pretension Gap: 0.120 to 0.180 mm.

NOTE

Connecting rod bearing shells are precision finished

and should not be bored or scraped.
