Figure 8-40. Connecting rod bearings and bushings.
14. Remove the Connecting Rod Bearings (Item #22) from each rod and cap.
If
the
bearings are snug or pinched, use a soft-faced hammer and a wood block to tap the
bearing loose. Drive in the direction
of
the groove in the rod so that the surfaces are not
damaged. Stubborn parts may need
to
be oiled or heated slightly to help break them
free. Keep the matched sets together with the same rod assemblies
if
you intend
to
use
them again.
15. Remove the Set Screw (Item #30) from the end
of
the Wrist Pin (Item #32). Use a
suitable arbor to press out the wrist pin bushing from the small end
of
the connecting
rod. Do not damage the inside surface of the rod.
16. Clean the connecting rod surface and inspect for scratches or burrs where the new wrist
pin bushing will be positioned. Wipe the parts clean with lint-free rags.
Use a suitable
arbor to press the new bronze wrist pin bushing into place so that it extends
1/8" (3.2
mm) beyond each side of the rod. After the bushings are pressed into the rods, ream the
bushings to 2.3765 to
2.377" (60.363 to 60.376 mm).
17. Clean the connecting rod and bearing surfaces before installation. Insert the new
bearings
as
a set into a matching rod and cap assembly. The wedge-shaped tab on the
bearing babbitt surface will fit one way only into correct position in the rod or cap
groove. Do not mix the halves or interchange with different bearings.
18. When the bearings are correctly inserted, position the rod and cap around the crankshaft
to
install. Lubricate the connecting rod internal bolt threads and fasten the rod to the cap
with Connecting Rod Cap Bolt Lock Washers (Item
#20) and Connecting Rod Cap Bolts
(Item #19). Torque the cap rod bolts
to
40 lb.-ft. (54 Nm).
