Starter Brush Inspection
11. lvleasure the brush length. lf it is not within the
service limit, replace the brush holder assembly.
Brush Length
Standard {New): 14.0-14.5 mm (0.55-0.57 in.)
Service Limit: 9.0 mm {0.35 in.)
Starter Field Winding Test
12. Check for continuity between the brushes (A). lf
there is no continuity. replace the armature
housing (B).
Check for continuity between each brush (A) and
the armature housing (B). li there is continuity,
replace the armature housing.
13.
Starter Brush Holder Test
14, Check that there is no continuity between the (+ )
brush holder {A) and ( ) brush holder (B}. lfthere
is continuity, replace the brush holder assembly.
Brush Spring Inspection
15. Insen the brush (A) into the brush holder, and bring
the brush into contact with the commutator, then
attach a spring scale (B) to the spring (C). Measure
the spring tension at the moment the spring lifts off
the brush. lf the spring tension is not within
specification, replace the spring.
Spring Tension: 13.7-17.7 N {1.40-1.80 kgf,

Charging System
Alternator Overhaul (cont'd)
Rectitier Test
16. Check for continuity in each direction, between the
B terminal and P terminals, and between the E
terminal and P terminals of each diode pair.
All diodes should have continuity in only one
direction. Because the rectifier diodes are designed
to allow current to pass in one direction, and the
rectifier is made up of eight diodes (four pairs). you
musttest each diode in both directions for
continuity with an ohmmeter that has diode
checking capability: a total of 16 checks.
. lf any diode is faulty. replace the rectifier
assembly. {Diodes are not available separately.)' lf all the diodes are OK, go to step 17.

Alternator Brush Length:
Standard (New): 10.5 mm (0.41 in.)
Service Limit: 1.5 mm (0.06 in.)
Rotor Slip Bing Test
18. Check that there is continuity between the slip rings
{A).
. lf there is continuity, go to step 19.. lf there is no continuity, replacethe alternator.
Check that there is no continuity between each slip
ring and the rotor (B) and the rotor shaft (C).

Cylinder Head
Valve Guide Replacement (cont'dl
Apply a thin coat of clean engine oil to the outside
of the new valve guide. Install the guide from the
camshaft side of the head; use the special tool to
drive the guide in to the specified installed height
(A) o{the guide (B). lf you have all 16 guidesto do,
you may have to reheat the head.
Valve Guide Installed Height:
Intake: 15.2 16.2 mm (0.598-0.638 in.)
Exhaust: 15.5 16.5 mm (0.610-0.650 in.)

\
10.Coat both reamer and valve guide with cutting oil.
Rotate the reamer clockwise the full length of the
valve guide bore.
O7HAH.PJ7O1OB
Continue to rotate the reamer clockwise while
removing it from the bore.
Thoroughly wash the guide in detergent and water
to remove any cutting residue.
Check the clearances with a valve (see page 6 32).
Verify that a valve slides in the intake and exhaust
valve guides without exening pressure.

Cylinder Honing
Only a scored or scratched cylinder bore should be
noneo.
Measure the cylinder bores {see page 7-15).
lf the block is to be reused, hone the cylinders and
remeasure the bores.
Hone the cylinder bores with honing oil and a fine(400 grit) stone in a 60 degree cross-hatch pattern
(A). Use only a rigid hone with 400 grit or finer
stone such as Sunnen, Ammco, or equivalent. Do
not use stones that are worn or broken.
When honing is complete, thoroughly clean the
engine block of all metal particles. Wash the
cylinder bores with hot soapy water, then dry and
oil them immediately to prevent rusting. Never use
solvent, it will only redistribute the grit on the
cylinder walls.
lf scoring or scratches are still present in the
cylinder bores after honing to the service limit,
rebore the cylinder block. Some light vertical
scoring and scratching is acceptable if it is not deep
enough to catch your fingernail and does not run
the full length of the bore.
