CONNECTING ROD BEARINGS
REMOVE AND INSTALL CONNECTING
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.
CAUTION: Be careful not to damage the crankshaft
journals. Do not turn the crankshaft while any of the
connecting rod caps are removed.
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 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 the connecting rod caps are installed
make sure that the numbers on the side of the caps are
next to and respective with the number on the side of the
5. Check the bearing clearance with wire (A). Put the caps (I) in
position on the connecting rods and install the nuts. Tighten the
nuts to a torque of 30 3 lb.ft. (40 4 N m). Put a mark on each
nut and the end of each bolt. Tighten the nuts 60 5° more
6. Remove the cap. Measure the thickness of the w-ire. The rod
bearing clearance must be .0030 .0015 in. (0.076 - 0.038 r1m1
). The maximum permissible clearance is .007 in. (0.18 1mm).
7. Put the caps in position on the connecting rods and install the nuts.
Tighten the nuts to a torque of 30 3 Ib.ft. (40 - 4 N m). Put a
mark on each nut and the end of each bolt. Tighten the nuts 60
8. Do Steps I through 7 again for the other bearings.
