Typical example
2. Clean the bearing surface of connecting rod (1)
and connecting rod cap (5). Ensure that number
(X) on connecting rod cap (5) aligns with number
(X) on connecting rod (1).
3. Install upper connecting rod bearing (3) to
connecting rod (1). Lubricate the bearing surface
of the connecting rod bearing with clean engine oil.
4. Carefully pull connecting rod (1) against the
crankshaft pin.
Note: Use tape or rubber tubing on connecting rod
bolts (2) in order to protect the crankshaft journals.
The sharp edges of the connecting rod bolts could
damage the crankshaft journals.
5. Clean the connecting rod cap. Install lower
connecting rod bearing (4) to connecting rod cap
(5).
6. Lubricate the pin of the crankshaft and lubricate
lower connecting rod bearing (3) with clean engine
oil.
NOTICE
When the connecting rod caps are installed, ensure
that the identification marks are aligned.
7. Install connecting rod cap (5).
8. Install nuts (4).
For 402D-05 and 403D-07 engines, tighten nuts
(4)toatorqueof23N·m(16lbft).
For 403D-11 and 404D-15 engines, tighten nuts
(4) to a torque o
f32N·m(24lbft).
For 403D-15, 403D-15T, 403D-17, 404D-22,
404D-22T and 4
04D-22TA engines, tighten nuts
(4) to a torque of 52 N·m (38 lb ft).
9. Ensure that th
e installed connecting rod assembly
has tactile side play. Carefully rotate the crankshaft
in order to ensure that there is no binding.
Note: If all connecting rod bearings require
replacement on a four cylinder engine, the procedure
canbecarrie
d out on two cylinders at the same time.

pairs of cylinders. 1 with 4 and 2 with 3. Ensure
that both pai
rs of the connecting rod bearings
are installed before changing from one pair of
cylinders to another pair of cylinders. Refer
