PISTON & ROD ASSEMBLY
1. Remove cylinder head assembly. Remove oil pan. Mark connecting rod caps for reassembly reference. Remove rod nuts. Remove lower
rod cap and bearing. Tap piston out top of cylinder block. DO NOT scratch crank journal or cylinder walls during removal.
2. Repeat procedure for remaining pistons. Keep removed parts in order to ensure installation to original position. Position piston assembly
in correct cylinder bore. Align piston mark "F" (1.3L), or notch (1.6L) located at piston pin bore area, and connecting rod oil gr o o ve
toward engine front. To complete installation, reverse removal procedure. Tighten all bolts and nuts to specification. See TORQUE
SPECIFICATIONS table at end of article.
FITTING PISTONS
1. With piston assembly removed, remove piston rings and clean piston. Measure piston outer diameter in thrust direction, below oil ring
groove. Diameter is 2.793-2.794" (70.954-70.974 mm) for 1.3L engines and 3.0690-3.0698 (77.954-77.974) for 1.6L engines.
2. Place piston upside down in cylinder from which it was removed. Using a feeler gauge, measure clearance between piston and cylinder
bore. If clearance is not within specification, bore cylinder and replace piston as necessary. See CYLINDER BLOCK
table in ENGINE
SPECIFICATIONS at end of article.
PISTON RINGS
Install rings on piston. Ensure marked side of rings are in proper position. Set ends of rings to proper position. See Fig. 9
.

PISTON PIN REPLACEMENT
1. With piston removed and cleaned, mark piston-to-rod to ensure proper reassembly. Using Piston Pin Remover/Installer Set (D81L-6135-
A for 1.3L or D90P-6135-AH for 1.6L), place piston and rod assembly in press.
2. Apply pressure and press piston pin from piston assembly. Keep all removed components together for reassembly. Remove piston and
rod from press and inspect.
3. Using a micrometer, measure piston pin O.D. in several areas. Measure piston pin I.D. Measure I.D. of piston pin bore and rod pin bore.
Replace components if not within specifications. See, at end of article, PISTONS PINS & RINGS
table in ENGINE
SPECIFICATIONS
4. If measurements of rod, piston and pin are within specification, reassemble using piston pin assembly set. Ensure piston-to-rod position
is proper, with connecting rod oil groove on side of piston marked "F" or by a notch. Lubricate pin with engine oil before reassembly.
With piston assembly reassembled, rod should fall by its own weight with piston held horizontally. Repeat procedure for remaining
pistons.
Rod Bearings Check rod bearing for abnormal wear. Check crankshaft journal. Check rod bearing-to-crankshaft clearance with Plastigage.
Machine or replace as necessary. See, at end of article, CRANKSHAFT MAIN & CONNECTING ROD BEARINGS
table under ENGINE
SPECIFICATIONS.
CRANKSHAFT & MAIN BEARINGS
1. Drain oil and remove oil pan. Ensure main bearing caps are marked for installation to original location and position.

3. If voltage is not present or is less than 8 volts at starter solenoid terminal "S", malfunction in circuit to terminal "S" is indicated. Proceed
to the following tests.
IGNITION SWITCH TEST
1. Locate ignition switch connector under dash. Using a 12-volt test light or voltmeter, ensure voltage is present on Black/Yellow wire
when ignition switch is turned to RUN or ON position. This will verify proper operation of ignition switch.
2. If there is no voltage on Black/Yellow wire, the problem is either ignition switch or circuit between battery and ignition switch.
CLUTCH ENGAGE SWITCH (M/T) TEST
Unplug clutch engage switch from main wiring harness. Using an ohmmeter, check for continuity across switch terminals. Continuity should
exist when switch plunger is pushed in and should not exist when switch plunger is released. If clutch engage switch does not operate as
specified, replace switch.
NEUTRAL SAFETY SWITCH (A/T) TEST
Unplug neutral safety switch from main wiring harness. Using an ohmmeter, check for continuity across switch terminals "A" and "B". See Fig.
2 . Place transmission shift selector in Park or Neutral position. Continuity should exist between terminals "A" and "B". Continuity should not
exist in any other transmission shift selector positions. If switch does nor operate as specified, replace switch.

1. Disconnect and ground coil wire from distributor cap to prevent engine from starting. Connect remote starter switch between starter
solenoid terminal "S" and battery positive terminal. See Fig. 3
.
2. Using a digital voltmeter set on low scale, connect positive voltmeter lead to battery positive terminal. Connect negative lead to starter
solenoid terminal "M". See Fig. 3
.
3. Engage remote starter switch. Observe and record voltmeter reading. Voltmeter reading should be less than .5 volt. If voltage at terminal
"M" is greater than .5 volt, move negative voltmeter lead to solenoid terminal "B", and repeat test.
4. If voltage at terminal "B" is less than .5 volt, inspect solenoid cable connections and solenoid contacts for problem.
5 . Cl ean so l en o id t ermin al s "B", "M" an d "S", an d rep eat st ep s 1 ) through 4). If voltmeter still reads greater than .5 volt at termin al "M"
and less than .5 volt at terminal "B", solenoid contacts are bad.
6. If voltmeter reads greater than .5 volt at terminal "B", clean cables and connections at solenoid. If voltmeter still reads greater than .5
volt, check for poor positive battery cable connection or bad cable. Repair or replace as necessary.
7. To locate excessive voltage drop, move negative voltmeter lead toward battery, and check each connection point. When high voltmeter
reading is no longer present, last connection point is bad.
NOTE:Make all voltm eter connections at com ponent term inal rather than at cable or wire end.

STARTER GROUND CIRCUIT TEST
1. Disconnect and ground coil wire from distributor cap to prevent engine from starting. Connect remote starter switch between starter
solenoid terminal "S" and battery positive terminal. See Fig. 1
.
2. Using a digital voltmeter set on low scale, connect positive voltmeter to starter motor housing. Ensure connection point is clean and free
of rust and grease. Connect negative voltmeter lead to negative battery terminal.
3. Engage remote starter switch and crank engine. Observe and record voltmeter reading. Voltmeter should read .2 volt or less. If voltage
drop is greater than .2 volt, clean negative battery cable connections at battery and body connections. Retest to ensure problem has been
corrected.
4. If voltage drop is still excessive, replace negative battery cable(s) as necessary. If battery cables test okay, and starter still cranks slowly
or not at all, remove and repair starter motor.
BENCH TESTING
STARTER NO-LOAD TEST
Remove starter. Place starter on bench. Connect a fully charged 12-volt battery, voltmeter, ammeter and remote starter switch to starter. See
Fig. 4
. Engage remote starter switch. Starter should rotate smoothly. Ensure voltage and amperage draw is less than maximum specification at
5000 RPM minimum. See NO-LOAD TEST SPECIFICATIONS table. If voltage and/or amperage is higher than specifications, disassemble
starter and determine cause.
