Removal (cont'dl
6. Remove the bolts. To prevent warpage, unscrew the
bolts in sequence 1/3 turn at a time; repeat the
sequence until all bolts are loosened.
Remove the rod caps/bearings and main caps/bear-
ings, Keep all caps/bearings in order
Lift the crankshaft out of the engine. being careful
not to damage the journals.

Remove the upper bearing halves from the connecting
rods, and set them aside with their respective caps.
Reinstall the main caps and bearings on the engine
in proper order.
lf you can feel a ridge of metal or hard carbon
around the top of each cvlinder, remove it with a
ridge reamer. Follow the reamer manufacturer's
instructions. lf the ridge is not removed, it may
damage the pistons as they 8re pushed out.

Use the wooden handle of a hammer to drive the
pistons out.
13.Reinstall the connecting rod bearings and caps after
removing each piston/connecting rod assembly.
To avoid mixup on reassembly, mark each piston/
connecting rod assembly with its cylinder number.
NOTE: The existing number on the connecting rod
does not indicate its position in the engine, it indi-
cates the rod bore size.

Coat the thrust washer surtaces and bolt threads
with oil.
Installthe main bearing caps.
Check clearance with plastigage (see page 7-7), then
tighten the bearing cap bolts in 2 steps.

NOTE: Whenever any crankshaft or connecting rod
bearing is replaced, it is necessary after reassembly
to run the engine at idling speed until it reaches
normal operating temperature, then continue to run
it for approximatelY 15 minutes.
10.Clean and dry the right side cover mating surfaces.
Apply liquid gasket, part No. 08718 - 0001 or 08718
- 0003, evenly to the block mating surface of the
right side cover and to the inner threads of the bolt
holes. Install it on the cylind€r block

NOTE:
. Do not install the parts if five minutes or more
have elapsed since applying the liquid gasket.
Instead, reapply liquid gasket after removing the
old residue.
. After assembly, wait at least 30 minutes before
filling the engine with oil.

Check the housing-to-outer rotor radial clearance. lf
the housing-to-outer rotor radial clearance exceeds
the service limit, reDlace the set of inner and outer
rotors and/or the pump housing,
Housing-to-Outer Rotor Radial Clearance
Standard lNewl: 0.10 - 0.19 mm
{0.004 - 0.007 in}
Service Limit: 0.20 mm {0.008 inl
Inspect both rotors and the pump housing for scor-
ing or other damage. Replace pans if necessary.
Remove the old oil seal from the oil pump.
Gently tap in the new crankshaft oil seal until the
special tool bottoms on the pump.

Check that the oil pump turns freely.
Apply a light coat ot oil to the seal lip.
Clean and dry the oil pump mating surfaces.
Install the two dowel pins and a new O-ring on the
cylinder block.
Apply liquid gasket, part No. 08718-0001 or 08718-
0003, to the cylinder block mating surface of the oil
pump. Apply the liquid gasket evenly, in a narrow
bead centered on the mating surface. Do not apply
liquid gasket to the O-ring grooves.
Apply liquid gasket to the inner threads of the bolt
noles.

align the retainer locking pawls with the connector
grooves. Then press the quick-connect fittings onto
the pipe until both retainer pawls lock with a click-
Ing sound.
NOTE: lf it is hard to connect, put a small amount of
new engine oil on the pipe end.
5. Make sure the connection is secure and that the pawls
are firmly locked into place; check visually and bypulling the connector.
Reconnect the battery negative cable, and turn the

about two seconds, and fuel pressure will rise. Repeat
two or three times, and check that there is no leakage
in the fuel supply system.
