1. Drain and remove the oil pan.
CAUTION - The EPA warns that prolonged contact with used engine oil may
cause a number of skin disorders, incl uding cancer! You should make every
effort to minimize your exposure to used engine oil. Pr otective gloves should be
worn when changing the oil. Wash y our hands and any other exposed skin
areas as soon as possible after exposure to used engine oil. Soap and water, or
waterless hand cleaner should be used.

Fig. 7: Fabricated s eal installation tool
Both halves of the rear main oil s eal can be replaced without removing the
crankshaft. Always replace the upper and lower seal together. The lip should
face the front of the engine. Be very ca reful that you do not break the sealing
bead in the channel on the out side portion of the seal while installing it. An
installation tool can be fabricat ed to protect the seal bead.
1. Remove the oil pan, oil pump and rear main bearing cap.
2. Remove the oil seal from the bearing cap by prying it out.
3. Remove the upper half of the seal wit h a small punch. Drive it around far
enough to be gripped with pliers.
4. Clean the crankshaft and bearing cap.
5. Coat the lips and bead of the seal with light engine oil, keeping oil from
the ends of the seal.
6. Position the fabricated tool bet ween the crankshaft and seal seat.
7. Position the seal between the cranks haft and tip of the tool so that the
seal bead contacts the ti p of the tool. The oil seal lip should face the
FRONT of the engine.
8. Roll the seal around the crankshaft us ing the tool to protect the seal bead
from the sharp corner s of the crankcase.
9. The installation tool should be le ft installed until the seal is properly
positioned with both ends fl ush with the block.
10. Remove the tool.
11. Install the other half of the seal in the bearing cap using the tool in the
same manner as before. Light thumb pressure should install the seal.
12. Install the bearing cap with sealant applied to the mating areas of the cap
and block. Keep sealant from the ends of the seal.
13. Torque the rear main bear ing cap to specifications.
14. Install the oil pump and oil pan.
15. Fill the engine with engine oil, st art the engine and check for leaks.

2. Drain the engine oil and remove the oil pan.
3. Remove the rear main bearing cap.
4. Insert packing tool J-29114-2 or equi
valent, against 1 end of the seal in
the cylinder block. Drive the old seal gently into the groove until it is
packed tight. This will vary from
1/4 in. (6mm) to 3/4 in. (19mm) depending
on the amount of pack required.
5. Repeat the procedure on t he other end of the seal.
6. Measure the amount the seal wa s driven up on one side and add
1/16 in.
(1.6mm). Using a suitable cutting tool, cut that length from the old seal
removed from the rear main beari ng cap. Repeat the procedure for the
other side. Use the rear main bear ing cap as a holding fixture when
cutting the seal.
7. Install guide tool J-29114-1 or equi valent, onto the cylinder block.
8. Using the packing tool, work the shor t pieces cut in Step 6 into the guide
tool and then pack into the cylinder block. The guide tool and packing
tool are machined to provide a built in stop. Use this procedure for both
sides. It may help to use oil on the short pieces of the rope seal when \
packing them into the cylinder block.
9. Remove the guide tool.
10. Apply Loctite® 414 or equivalent, to the seal groove in the rear main
bearing cap. Within 1 minute, insert a new seal into the groove and push
into place with tool J-29590 until the seal is flush with the block. Cut the
excess seal material with a sharp cu tting tool at the bearing cap parting
line.
11. Apply a thin film of chassis grease to the rope se al. Apply a thin film of
RTV sealant on the bearing cap mati ng surface around the seal groove.
Use the sealer sparingly.
12. Plastigage® the rear main bea ring cap as outlined in MEASURING
REAR MAIN CLEARANCE in this section and check with specification. If
out of specification, check for fr ying of the rope seal which may be
causing the cap to not seat properly.
13. Install all remaining com ponents and inspect for leaks.
FLYWHEEL AND RING GEAR
REMOVAL & INSTALLATION
The ring gear is an integral part of the flywheel and is not replaceable.
1. Remove the transmission.
2. Remove the six bolts attaching t he flywheel to the crankshaft flange.
Remove the flywheel.
3. Inspect the flywheel for cracks, and inspect the ring gear for burrs or
worn teeth. Replace the flywheel if any damage is apparent. Remove
burrs with a mill file.
4. Install the flywheel. Th e flywheel will only attach to the crankshaft in one
position, as the bolt holes are unevenly spaced. Install the bolts and
torque to specification. Tighten bolts in crisscross pattern.

then you have wrist pin bushings in the rods. There should not be any
excessive play between the wrist pin
and the rod bushing. Normal clearance for
the wrist pin is approx. 0.001-0.002 in. (0.025mm-0.051mm).

Fig. 4: Measure the piston's outer diam eter, perpendicular to the wrist pin, with
a micrometer
Use a micrometer and measure the diamet er of the piston, perpendicular to the
wrist pin, on the skirt. Com pare the reading to its original cylinder measurement
obtained earlier. The diffe rence between the two readings is the piston-to-wall
clearance. If the clearance is within specif ications, the piston may be used as is.
If the piston is out of specification, but the bore is not, you will need a new
piston. If both are out of specificati on, you will need the cylinder rebored and
oversize pistons installed. Generally if two or more pistons/bores are out of
specification, it is best to rebore the entire block and purchase a complete set of
oversize pistons.
CONNECTING ROD
You should have the connecting rod chec ked for straightness at a machine
shop. If the connecting rod is bent, it will unevenly wear the bearing and piston,
as well as place greater stress on these components. Any bent or twisted
connecting rods must be replaced. If the rods are straight and the wrist pin
clearance is within specifications, t hen only the bearing end of the rod need be
checked. Place the connecting rod into a vi ce, with the bearing inserts in place,
install the cap to the rod and torque t he fasteners to specifications. Use a
telescoping gauge and carefully measure t he inside diameter of the bearings.
Compare this reading to the rods or iginal crankshaft journal diameter
measurement. The difference is the oil clearance. If the oil clearance is not
