FUEL INJECTOR AND FUEL TUBE
Revision: 2004 November 2004 FX35/FX45

Lubricate O-ring with new engine oil.

Do not clean O-ring with solvent.

Make sure that O-ring and its mating part are free of foreign material.

When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not
to twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it
quickly into fuel tube.

Insert O-ring straight into fuel tube. Do not decenter or twist it.

Insert fuel damper and fuel sub-tube straight into fuel tube.

Tighten mounting bolts evenly in turn.

After tightening mounting bolts, make sure that there is no gap between flange and fuel tube.
2. Install O-rings to fuel injector paying attention to the items below.
CAUTION:

Upper and lower O-ring are different. Be careful not to confuse them.

Handle O-ring with bare hands. Never wear gloves.

Lubricate O-ring with new engine oil.

Do not clean O-ring with solvent.

Make sure that O-ring and its mating part are free of foreign material.

When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it
quickly into fuel tube.

Insert O-ring straight into fuel tube. Do not decenter or twist it.
3. Install fuel injector to fuel tube with the following procedure.
a. Insert clip into clip mounting groove on fuel injector.

Insert clip so that lug “A” of fuel injector matches notch “A” of
clip.
CAUTION:

Do not reuse clip. Replace it with a new one.

Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached.

Insert it while matching it to the axial center.

Insert fuel injector so that lug “B” of fuel tube matches notch
“B” of clip.

Make sure that fuel tube flange is securely fixed in flange fix-
ing groove on clip.
c. Make sure that installation is complete by checking that fuel
injector does not rotate or come off.
4. Install spacers on intake manifold.Fuel tube side : Blue

VALVE SEAT CONTACT

After confirming that the dimensions of valve guides and valves
are within specifications, perform this procedure.

Apply prussian blue (or white lead) onto contacting surface of
valve seat to check the condition of the valve contact on the sur-
face.

Check if the contact area band is continuous all around the cir-
cumference.

If not, grind to adjust valve fitting and check again. If the contact-
ing surface still has NG conditions even after the re-check,
replace valve seat.
VALVE SEAT REPLACEMENT
When valve seat is removed, replace with oversized (0.5 mm, 0.020 in) valve seat.
1. Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this.
CAUTION:
Prevent to scratch cylinder head by excessive boring.
2. Ream cylinder head recess diameter for service valve seat.

Be sure to ream in circles concentric to the valve guide center.
This will enable valve to fit correctly.
3. Heat cylinder head to 110 to 130°C (230 to 266°F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head.
CAUTION:

Avoid directly touching cold valve seats.

Cylinder head contains heat. When working, wear protective equipment to avoid getting burned.

Undersize Bearing Usage Guide

Use undersize (US) bearing when oil clearance with standard size main bearing is not within specification.

When using undersize (US) bearing, measure the bearing inner diameter with bearing installed, and grind
journal until oil clearance falls within specification.
CAUTION:
Keep fillet R [1.5 mm (0.059 in)] when grinding crankshaft jour-
nal in order to use undersize bearing (All journals).

CAMSHAFT
Revision: 2004 November 2004 FX35/FX45
VALVE LIFTER HOLE DIAMETER

Measure inner diameter of valve lifter hole of cylinder head with
inside micrometer.
VALVE LIFTER CLEARANCE

(Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter outer diameter)

If it exceeds the standard, referring to each standard of valve lifter outer diameter and valve lifter hole
diameter, replace either or both valve lifter and cylinder head.
INSTALLATION
1. Install valve lifters and adjusting shims if removed.

Install it in the original position.
2. Install camshafts.

Follow your identification marks made during removal, or fol-
low the identification marks that are present on new cam-
shafts for proper placement and direction.

Install camshaft so that dowel pin on front end face are posi-
tioned as shown in the figure. (No. 1 cylinder TDC on its com-
pression stroke)
NOTE:
Though camshaft does not stop at the position as shown in
the figure, for the placement of cam nose, it is generally
accepted camshaft is placed for the same direction of the fig-
ure.Standard : 34.000 - 34.016 mm (1.3386 - 1.3392 in)

Use Undersize Bearing Usage Guide

When the specified main bearing oil clearance is not obtained with standard size main bearings, use
underside (US) bearing.

When using undersize (US) bearing, measure the main bearing inner diameter with bearing installed, and
grind main journal so that the main bearing oil clearance satisfies the standard.

In grinding crankshaft main journal to use undersize bear-
ings, keep the fillet R [1.5 mm (0.059 in)].
