3-4. ENGINE DISASSEMBLY
NOTE:
3) Remove distributor assembly.
l Observe critically before starting to remove a
component or part by loosening bolts, nuts
and the like. What you may find before and
during disassembly is valuable information
necessary for sucessful reassembly.
l Be careful in .handling aluminum-alloy parts.
They are softer than steel or cast-iron parts
and their finished surfaces more easily- take
scratch marks.
l Have trays and pans ready for setting aside
disassembled parts in an orderly manner.
Place parts in trays and pans in such a way_.
that they can be readily identified. Put matchFig. 3-4-3
marks or tags on them, as necessary, so that
they will go back to where they came from.
4) Remove the fuel pump and rod.
Carry out engine disassembly in the following
NOTE:
sequence :When removing pump and distributor gear case,
1) Loosen drain plug and drain out engine oil.place waste or receiver under gear casa.

b) Remove valve stem oil seal from valve guide,
and then valve spring seat.
NOTE:
Do not reuse oil seal once disassembled. Besure to use new oil seal when assembling.

c) Using special tool (F), drive valve guide out from combustion chamber side to valve
spring side (Figure 3-4-29).
NOTE:
Do not reuse valve guide once disassembled.
Be sure to use new valve guide (Oversize) when
assembling.
NOTE:
Place disassembled parts except valve stem seal
and valve guide in order, so that they can be
installed in their original positions.
29) Remove flywheel, using special tool (A)
as shown.

Crankshaft Main (Journal) Bearings
General informations:
l Service main bearings are available in standard-
size and 0.25 mm (0.0098 in) undersize, and
each of them has 5 kinds of bearings differ-
ing in tolerance.
l The upper half of bearing has oil groove as
indicated in Fig. 3~5-42. Install this half with
oil groove to cylinder block.
Fig. 3-5-40 Measuring thrust play of crankshaft
l Out-of-round and taper (uneven wear):
An unevenly worn crankshaft journal shows
up as a difference in diameter at a cross
section or along its length (or both). This
difference, if any, is to be determined from
micrometer readings.
If any of journals is badly damaged or if the
amount of uneven wear in the sense explained
above exceeds its limit, regrind or replace the
crankshaft.

When installing each bearing cap to cylinder
block, point arrow mark toward crankshaft
pulley side and install each cap from crank-
shaft pulley side to flywheel side in ascending

1) Inspect oil seal lip for fault or other damage.
Replace as necessary.
2) Inspect outer and inner rotors, rotor plate,
and oil pump case for excessive wear or
damage.
l Radial clearance:
Check radial clearance between outer rotor
and case, using thickness gauge.
If clearance exceeds its limit, replace outer
rotor or case.

3) install piston and connecting rod assembly
into cylinder bore.
@Apply engine oil to pistons, rings, cylinder
walls, connecting rod bearings and crank-
pins.
@Put guide hoses over connecting rod bolts as
shown in Fig. 3-6-18. These guide hoses
protect crankpin and thread of rod bolt
from damage during installation of connect-
ing rod and piston assembly.

@When installing piston and connecting rod
assembly into cylinder bore, point arrow
mark on each piston head to crankshaft
pulley side.

@ Use piston ring compressor (Special tool) to
compress rings. Guide connecting rod into
place on the crankshaft.
Using a hammer handle, tap piston head to
install piston into bore. Hold ring compres-
sor firmly against cylinder block until all
piston rings have entered cylinder bore.
