14. NOTE: Install the connecting rod bearings dry when the clearance checks are made. Put clean
engine oil on the connecting rod bearings for final assembly.
NOTICE
Be sure the tabs in the back of the connecting rod bearings are in the
tab grooves of the connecting rod and cap.
3. Install the upper half of the rod bearing in the connecting rod, and put the connecting rod in
position on the crankshaft.
4. Install the lower half of the rod bearing in the connecting rod cap.
The serviceman must be very careful to use Plastigage correctly. The following points must be
remembered:
...Make sure that the backs of the bearings and the bores are clean and dry.
...Make sure that the bearing locking tabs are properly seated in their slots.
...The crankshaft must be free of oil where the Plastigage touches it.
...Put a piece of Plastigage on the crown of the bearing half that is in the cap. Do not allow the
Plastigage to extend over the edge of the bearing.
...Install the bearing cap using the correct torque-turn specifications. Do not use an impact wrench.
Be careful not to dislodge the bearing when the cap is installed.
...Do not turn the crankshaft with the Plastigage installed.
...Carefully remove the cap, but do not remove the Plastigage. Measure the width of the Plastigage
while it is in the bearing cap or on the crankshaft journal. Do this by using the correct scale on the
package. Record the measurements.
...Remove the Plastigage before installing the cap.
When using Plastigage, the readings can sometimes be unclear. For example, all parts of the
Plastigage are not the same width. Measure the major widths to make sure that they are within the
specification range. Also, experience has shown that when checking clearances tighter than 0.10
mm (.004") the readings may be low by 0.013 to 0.025 mm (.0005 to .0010"). Out-of-round

15. journals can give faulty readings. Also, journal taper may be indicated when one end of the
Plastigage is wider than the other.
For complete details concerning measuring bearing clearances, see Engine Bearings And
Crankshafts, Form No. SEBD0531.
5. Use Plastigage (A) to check the connecting rod bearing clearance.
6. Put Plastigage (A) on the connecting rod bearing.
7. Put 2P2506 Thread Lubricant on the threads of the rod bolts and seat surfaces of the nuts.
NOTICE
When connecting rod caps are installed, make sure the number on the
side of the cap is next to and respective with the number on the side of
the connecting rod.
8. Install connecting rod cap (2). Install the nuts. Tighten the nuts to a torque of 41 ± 4 N·m (30 ±
3 lb.ft.). Put a mark on each nut and the end of each bolt. Tighten the nuts 60° ± 5° more.
9. Remove the connecting rod caps. Measure the thickness of the Plastigage. The connecting rod
bearing clearance must be 0.043 ± 0.140 mm (.0017 to .0055 in.) for new bearings. The maximum
clearance with used bearings is 0.15 mm (.006 in.).
10. Install the connecting rod caps, and tighten the nuts as in Step 8.
11. Do Steps 1 through 9 for the remainder of the connecting rod bearings.

26. 1. Put the engine in position on tooling (A).
2. Put clean engine oil on the bearing journals and 2P2506 Thread Lubricant on the cam lobes of
the camshaft.
3. Carefully install camshaft (1) in the cylinder block. Hold the camshaft up during installation so
the camshaft bearings will not be damaged.
4. Install washer (3), lock (2) and the bolts that hold the camshaft in place. Bend the tabs of the
lock against one of the flats of each bolt head.
5. Install two 3/8"-16 NC guide bolts (4) in the end of the camshaft.
6. Put camshaft drive gear (5) in position on the guide bolts. Make sure the marks on the idler gear
and the crankshaft drive gear are in alignment with the marks on the camshaft drive gear.
7. Turn the camshaft, and make sure the "C" mark on the camshaft drive gear is in alignment with
the "C" mark on the crankshaft drive gear.
NOTE: If a new gear has been installed, it will be necessary to check the engine timing to make
sure the timing is correct. See Remove And Install Fuel Injection Pump Housing And Governor.
8. Install two bolts in the camshaft gear, and remove the guide bolts. Install the remaining bolts in
the camshaft drive gear. Tighten the bolts to a torque of 55 ± 7 N·m (41 ± 5 lb.ft.).

Remove And Install Crankshaft Main Bearings
START BY:
a. remove oil pan
1. Put the engine on tooling (A).
2. Remove the bolts that hold main bearing cap (1). Remove main bearing cap (1) and the lower
half of the main bearing.
3. Remove the bearing from the cap.

32. NOTICE
If the crankshaft is turned in the wrong direction, the tab of the
bearing will be pushed between the crankshaft and cylinder block. This
can cause damage to either or both.
NOTE: The center and two end main journals have no oil hole. To remove these bearings, put a
thin piece of soft material that will not damage the crankshaft journal against the end of the
bearing opposite the tab. Hit the bearing with the soft material until the tab of the bearing is free
from the groove in the cylinder block. Remove the upper half of the main bearing.
4. Remove the upper half of the other main bearings as follows:
a. Turn the crankshaft until tool (B) can be installed in the crankshaft journal. Install tool (B).
b. Turn the crankshaft in the direction which will push the upper main bearing out, tab end first.
c. Check the condition of the bearings. (See Guideline For Reusable Parts, Main And Connecting
Rod Bearings, Form No. SEBF8009.)
5. Remove crankshaft thrust bearings (2) from each side of the No. 3 main bearing saddle.
NOTE: Install the main bearings dry when the clearance checks are made. Put clean engine oil on
the main bearings for final assembly. Also, be sure the tabs on the back side of the main bearings
fit in the grooves of the main bearing caps and cylinder block.
6. Clean the surfaces in the cylinder block for the main bearings. Use tool (B), and install new
upper halves of main bearings (bearings with the oil hole) in the cylinder block. Do not put oil on
the bearing.

33. 7. Clean the surfaces of the main bearing caps for the main bearings. Install the new lower halves
of the main bearings in the main caps without oil.
Typical Example
The serviceman must be very careful to use Plastigage correctly. The following points must be
remembered:
...Make sure that the backs of the bearings and the bores are clean and dry.
...Make sure that the bearing locking tabs are properly seated in their slots.
...The crankshaft must be free of oil where the Plastigage touches it.
...If the main bearing clearances are checked with the engine upright or on its side, the crankshaft
must be supported. Use a jack under an adjacent crankshaft counterweight and hold the crankshaft
against the crown of the bearing. If the crankshaft is not supported, the weight of the crankshaft
will cause incorrect readings.
...Put a piece of Plastigage on the crown of the bearing half that is in the cap. Do not allow the
Plastigage to extend over the edge of the bearing.
...Install the bearing cap using the correct torque-turn specifications. Do not use an impact wrench.
Be careful not to dislodge the bearing when the cap is installed.
...Do not turn the crankshaft with the Plastigage installed.
...Carefully remove the cap, but do not remove the Plastigage. Measure the width of the Plastigage
while it is in the bearing cap or on the crankshaft journal. Do this by using the correct scale on the
package. Record the measurements.
...Remove the Plastigage before installing the cap.
When using Plastigage, the readings can sometimes be unclear. For example, all parts of the
Plastigage are not the same width. Measure the major widths to make sure that they are within the
specification range. Also, experience has shown that when checking clearances tighter than 0.10
mm (.004") the readings may be low by 0.013 to 0.025 mm (.0005 to .0010"). Out-of-round
journals can give faulty readings. Also, journal taper may be indicated when one end of the
Plastigage is wider than the other.
For complete details concerning measuring bearing clearances, see Engine Bearings And
Crankshafts, Form No. SEBD0531.
8. Check the main bearing clearance with Plastigage (C) as follows:
