9. Perform the following checks and adjustments:. Check that the spring clip on the ends of the drive-shaft and intermediate shaft clicks into place. Usenew spring clips.. Adjust the shift cable (see section l4).. Adjust the throttle cable (see section 11).. Refill the engine with engine oil (see page g-4).
. Refill the transmission with oil or fluid (see sec-tion 13 or 14).
. Refill the radiator with engine coolant (see page
10_5).
. Bleed air from the cooling system with theheater valve open (see page l0-5).. Clean the battery posts and cable terminals withsandpaper, assemble them, then apply grease toDrevent corrosron.. Inspect for fuel leakage (see section 1l).After assembling fuel line pans, turn on the igni-tion switch (do not operate the starter) so thatthe fuel pump operates for approximately twoseconds and the fuel Iine pressurizes.
Repeat this operation two or three times, andcheck for fuel leakage at any point in the fuel line.

Valve Guides
Replacement (cont'dl
5.
Working from the camshaft side, use the driver andan air hammer to drive the guide about 2 mm (O.l
in) towards the combustion chamber. This willknock off some of the carbon and make removaleasier. Hold the air hammer directly in line with thevalve guide to prevent damaging the driver.
CAUTION: Always wear satety goggles or a faceshield when driving valve guidss.
Turn the head over and drive the guide out towardthe camshaft side of the head.
li a valve guide won't move, drill it out with a 8.0mm (5/16 in) bit, then try again. Dritt guides onty inextreme cases; you could damage the cylinder headif the guide breaks.
Remove the new guide(s) from the freezer, one at atlme, as you need them.

1. Apply a coat of engine oil to the ring grooves andcylinder bores.
It the crankshaft is already installed.
2. Set the crankshatt to BDC for each cylinder.3. Remove the connecting rod caps, and slip short sections of rubber hose over the threaded ends of theconnecting rod bolts.
4. lnstall the ring compressor, and check that the bear-ang is securely in place.
5. Position the piston in the cylinder, and tap it in usingthe wooden handle of a hammer. Maintain down-ward force on the ring compressor to prevent ringstrom expanding before entering the cylinder bore.6. Stop after the ring compressor pops free, and checkthe connecting rod-to-crank journal alignmentbefore pushing piston into place.
7. Install the rod caps with bearings, and torque theNUIS IO:

the housing-to-outer rotor radial clearance exceeds
the service limit, reDlace the set of inner and outer
rotors and/or the pump housing,

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

NOTE:
. Do not install the pans if five minutes or more have
elapsed since applying liquid gasket. Instead, reapply
