(Connecting ro
ds in po sit ion)
Removal Procedure
Start By:
a. Remove the suc
tion pipe. Refer to Disassembly
and Assembly, “Engine Oil Pump - Remove”.
NOTICE
Keep all parts
clean from contaminants.
Contaminants may cause rapid wear and shortened
component lif
e.
Note: If all connecting rod bearings require
replacement on a four cylinder engine, the procedure
can be carried out on two cylinders at the same time.
The procedure can be carried out on the following
pairsofcylinders.1with4and2with3.Ensure
that both pairs of the connecting rod bearings
are installed before changing from one pair of
cylinders to another pair of cylinders..Refer
to Disassembly and Assembly, “Connecting Rod

Typical example
Note: The connecting rod and the connecting rod
cap should have matching numbers at position (X).
If necessary, make a temporary mark on connecting
rod (1) and on connecting rod cap (5).
1. Rotate the crankshaft until the piston is at the
bottom center p
osition. Remove nuts (6) and
remove connecting rod cap (5) from connecting
rod (1).
2. Remove lower connecting rod bearing (4) from
connecting rod cap (5).
3. Carefully push connecting rod (1) into the cylinder
bore. Remove upper connecting rod bearing (3)
from the conn
ecting rod.
Note: Use tape or rubber tubing on connecting rod
bolts (2) in o
rder to protect the crankshaft journals.
The sharp edges of the connecting rod bolts could
damage the crankshaft journals.

Installation Procedure
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
1. Inspect the pins of the crankshaft for damage.
If the crankshaft is damaged, replace the
crankshaf
t or recondition the crankshaft. Refer
to Disassembly and Assembly, “Crankshaft
- Remove” and Disassembly and Assembly,
