*1: Always use Genuine Honda Manual Transmission Fluid (MTF). Using motor oil can cause stiffer shifting because itdoes not contain the proper addtuves.*2: Always use Genuine Honda Premium Formula Automatic Transmission Fluid (ATF). Using a non-Honda ATF can affectshift quality.*3: Always use Genuine Honda DOT 3 B.ake Fluid, Using a non-Honda brake fluid can cause corrosion and decrease thelife of the system.'4: Always use Genuine Honda Power Steering Fluid-V or S. Using any other type of power steering fluid or automatictransmission fluid can cause increase v,/ear and poor steering in cold weather.

Engine Removal/lnstallation
2. Remove the strut brace.
Make sure iacks and safety stands ate placed plopel-
ly and hoist brackets are attached to the correct po-
sitions on the engine {see section 11,
Make sure the car will not rollolt stands and latl whileyou are wgrking under it.

CAUTION:
. Use fender covers to avoid damaging painted sur-
faces.
Unplug the wiring connectors carelully while holding
the coupler and the connector portion to avoid d8m-
age.
Mark all wiring and hoses to avoid misconnection.
Also. be sure that they do not contact other wiring
or hoses, or intedere with other parts.
NOTE: Anti-theft radios have a coded theft protection cir-
cuit. Be sure to get the customer's code number betore- Disconnecting the battery.- Removing the No.32 (7.5 A) fuse from the under
hood fuse/relay box.
Removing the radio
After service, reconnect power to the radio and turn it
on. When the word "CODE" is displayed, enter the cus
tomer's 5-digit code to restore radio operation.
1. Remove the hood (see section 20).
3.Disconnect the battery negative terminal first, then
the positive terminal.

Valve Installation'alve Inslallauon -
When installing valves in the cylinder head, coat
valve stems with oil belore inserting them into valve
guides, and make sure valves move up and down
smoothly.
When valves and springs are in place, lightly tap the
end of each valve stem two or three times to ensure
proper seating of valves and valve keepers (use plas
tic mallet).
NOTE: Tap the valve stem only along lts axrs so you
do not bend the stem.

lf measurement exceeds the service limit, recheck
usrng a new valve.
lf measurement is now within the service limit,
reassemble using a new valve.
lf measurement still exceeds limit, recheck using
alternate method below, then replace valve and
guide, if necessary.
NOTEr An alternate method of checking guide to stem
clearance is to subtract the O.D. of the valve stem, mea-
sured with a micrometer, from the l.D. o{ the valve
guide, measured with an inside micrometer or ball
ga uge.
Take the measurements in three places along the valve
stem and three places inside the valve guide.
The diiference between the largest guide measurement
and the smallest stem measurement should not exceed
the service limit

Reconditioning
ACTUALSEATINGSURFACE
VALVESEAT
Renew the valve seats in the cylinder head using avalve seat cutter.
NOTE: lf guides are worn (see page 6-26), replace
them {see page 6-27) before cutting the valve seats.
Carefully cut a 45" seat, removing only enoughmaterial to ensure a smooth and concentric seat.
Bevel the upper edge of the seat with the 30. cutterand the lower edge of the seat with the 60. cutter.Check width of seat and adjust accordingly.
Make one more very light pass with the 45o cutter toremove any possible burrs caused by the other cut-rers.

After resurfacing the seat, inspect for even valveseating: Apply Prussian Blue compound to the valveface. Insert the valve in its original location in thehead, then lift it and snap it closed against the seatseveral times.
PRUSSIAN BLUE COMPOUNO
6-29
o.The actual valve seating surface, as shown by theblue compound, should be centered on the seat.
lf it is too high (closer to the valve stem), you
must make a second cut with the 60" cutter tomove it down, then one more cut with the 45"
cutter to restore seat width.
lf it is too low (closer to the valve edge), you
must make a second cut with the 30. cutter tomove at up, then one more cut with the 45. cutterto restore seat width.
NOTE: The final cut should always be made with
the 45" cutter.
Insert intake and exhaust valves in the head andmeasure valve stem installed height.

To check main bearing-to-iournal oil clearance,
remove the main caps and bearing halves.
Clean each main iournal and bearing half with a
clean shop towel.
Place one strip of plastigage across each main iour-
na l-
NOTE: lf the engine is still in the car when you bolt
the main cap down to check clearance, the weight
of the crankshaft and flywheel will flatten the plasti'
gage further than just the torque on the cap bolt,
and give you an incorrect reading. For an accurate
reading, support the crank with a jack under the
counterweights and check only one bearing at a
trme.
Reinstall the bearing caps and cap bridge (B18C1,
B18C5 engines only)then torque the bolts.

NOTE: Do not rotate the crankshaft during inspec-

Remove the cap bridge (818C1, 818C5 engines
only), caps and bearings again, and measure the
widest part of the plastigage.

PLASTIGAGE STRIP
lf the plastigage measures too wide or too narrow,
{remove the engine if it's still in the car), remove the
crankshaft, and remove the upper half of the bear-
ing. lnstall a new, complete bearing with the same
color code (select the color as shown in the right
column), and recheck the clearance.
CAUTION: Do not file, shim. or scrape the bearings
or the caps to adiust clearance.
lf the plastigage shows the clearance is still incor-
rect, try the next larger or smaller bearing (the color
listed above or below that one), and check again.
NOTE: lf the oroDer clearance cannot be obtained
by using the appropriate larger or smaller bearings.
reolace the crankshaft and start over.

CAUTION: lf the codes ale indecipherable because of
an accumulation oI dirt and dust, do not scrub them
with a wire bru6h or scraper. Clean lhem only with sol-
vent or detergent.

CAUTION:
. Take care not to damage the contact surface ot
the metal gasket.
. When removing the piston/connecting rod, take
care not to hit the oil iet (818C1, 818C5 enginesl.
. ll the oil iet nozzle is damaged or bent, replace
the oil iet assembly {818C1, B18C5 engincs.
page 8-9).
Reinstall the rod bearings and caps after removing
each piston/connecting rod assembly.
l\4ark each piston/connecting rod assembly with its
cylinder number to avoid mixup on reassembly.
NOTE; The existing number on the connecting rod
does not indicate its position in the engine, it indi-
cates the rod bore size.
End Play
NOTE: End play should be inspected before removing
crankshaft.
Push the crank firmly away from the dial indicator, and
zero the dial against the end of the crank. Then pull the
crank firmly back toward the indicator; dial reading
should not exceed service limit.

necessary.
NOTE:
. Thrust washer thickness is tixed and must not be
changed either by grinding or shimming.
. Thrust washers are installed with grooved sides fac-
