start by:

a) remove oil pan

1. Turn the crankshaft until two pistons are at

bottom center. Remove connecting rod caps (1)

from the two-connecting rods. Remove the

lower half of the bearings from the caps.

2. Push the connecting rods away from the

crankshaft and remove the upper half of the

bearings.

3. Clean the surfaces where the bearings fit.

Install the upper half of the new bearings in the

rods. Put clean SAE 30 oil on the bearings and

crankshaft journals. Put the connecting rods in

position on the crankshaft.

4. Clean the surfaces where the bearings fit.

Install the lower half of the new bearings in the

caps. Put clean SAE 30 oil on the bearings, bolt

threads and contact surfaces of the nuts.

CAUTION: When installing connecting rod caps make

sure that the numbers on the side of the cap is next to

and respective with the number on the side of the

connecting rod.

5. Check the bearing clearance with wire (A). Put

the caps (1) in position on the connecting rods

and install the nuts. Tighten the nuts to a torque

of 30 3 lb.ft. (4.1 0.4 mkg). Put a mark on

each nut and the end of each bolt. Tighten the

nuts 60 5more.

6. Remove the cap. Measure the thickness of the

wire. The rod bearing clearance must be .0030

.0015 in. (0.076 0.038 mm). The maximum

permissible clearance is .007 in. (0.18 mm).

7. Put the caps in position on the connecting rods

and install the nuts. Tighten the nuts to a torque

of 30 3 lb.ft. (4.1 0.4 mkg). Put a mark on

each nut and the end of each bolt. Tighten the

nuts 60 5more.

8. Do Steps 1 through 7 again for other bearings.
