start by:
a) remove piston cooling jets
1.
Use tool (A) and turn the engine flywheel to
move the connecting rod cap bolts into a position
for removal.
2.
Remove bolts (I) to remove bearing caps (2) from
the crankshaft and connecting rod. Remove the
lower half of the bearings from caps (2).
3.
Push the connecting rods away from the
crankshaft and remove the upper halves of the
bearings from the rods.
NOTE: Install rod bearings dry when the clearance
checks are made. Put clean engine oil on the rod
bearings for final assembly.
4.
Clean the surfaces where the bearing halves fit.
Install bearing halves (3) in the rods and caps
(2). Put 5P960 Multipurpose Type Grease on
the bolt threads and contact surfaces of the bolts
and caps.
5.
Make a check of the bearing clearance with
Plastigage. Put caps (2) in position on the
connecting rods and make sure the number on
the side of the cap is next to and respective with
the number on the side of the connecting rod.
Tighten the bolts in the number sequence shown
as follows:
NOTICE
Do not use an impact wrench to tighten the bolts the
additional 90 50 of a turn more.
NOTE: Bolts (6) and (7) are on the end of the rod cap
opposite the end that has the location pin for correct
installation.
a) Tighten bolts No. 4 and 5 to a torque of 90
+ 5 Nm (65 + 4 lb. ft.).
b) Tighten bolts No. 6 and 7 to a torque of 90
+ 5 Nm (65 + 4 lb. ft.).
c) Tighten bolts No. 6 and 7 again to a torque
of 90 + 5 Nm (65 + 4 lb. ft.).
d) Tighten each bolt 90 + 50 of a turn more.
6.
Remove the cap and measure the Plastigage.
The rod bearing clearance must be 0.107 to
0.218 mm (.0042 to .0086 in.).
7.
Put clean engine oil on both halves of the rod
bearings. Put caps (2) in position and tighten the
bolts as in Step 5.
