following the

manufacturer's

instructions.

Measure

both

ends of

the

Plastigage

strip.

A

difference

of

0.025

mm

(0.001

in.) or

more

indicates a

tapered

journal.

Confirm

with

a

micrometer.

New bearing

clearance

and

the service

limit are

listed in Table

5.

Remove

all of

the

Plastigage

material

from the

crankshaft

journals

and the

connecting

rods.

8.

If the

rod bearing

clearance

is

greater

than

specified,

use

the

following

steps

for

new bearing

selection.

9.

The crankshaft

rod

journals

are

marked

with

letters

"A,"

"B

or

"C"

(A,

Figure 34)

on

the

counterbalance

weights.

The connecting

rods are

marked

with

numbers

"l,"

"2"

or

o'3"

(Figure

35).

10. Measure the

rod

journal

(A,

Figure 36)

with

a

micrometer.

If

the

rod

journal

dimension

is

within

the tolerances

stated

for

each

letter code

in

Table 6

the

bearing

can be

simply

selected

by

color

code.

Select

new

bearings

by cross-referencing

the

rod

journal

letters

(A,

Figure

34)

in the

horizontal

column of

Table 6 to

the

rod bearing

number

(Figure

35)

in the

vertical column.

Where the

2

columns

intersect,

the

new bearing

color

is

indicated.

Table 7

gives

the

bearing

insert

color

and

thickness.

I l. If any

rod bearing

journal

measurements

taken

during

inspection

do

not

fall

within the

tolerance

range

for the

stamped

letter codes,

the

serviceability

of

the

crankshaft

must be carefully

examined.

If

the

rod bearing

journal

in

question

is

not tapered,

out-of-round

or

scored

the crankshaft

may be still

used.

However,

the

bearing

selection

will

have

to

be

made based

on

the

measured

diameter

of the

bearing

journal

and

not by the

stamped

letter

code.

Honda

recommends

the

crankshaft

be

replaced

whenever a

rod bearing

journal

dimension

is beyond

the

specified

range of

the stamped

letter

code.

12.

After new

bearings

have been

installed,

recheck

clearance

by

repeating

this

procedure.

13.

Repeat Steps

6-12

for the

other

3 cylinders.

Inspection

l. Check

the

inside and

outside

surfaces

of

the

bearing

inserts

for

wear, bluish

tint

(burned),

flaking abrasion

and scoring.

If

the

bearings

are

good,

they

may be

reused.

If

any

insert

is

questionable,

replace

the

entire

set.

2. Clean the

main

bearing

inserts

and bearing

surfaces

of

the

crankshaft.

Measure

the

main

bearing

clearance

by

performing

the

following

steps.
