REMOVAL
(1) Remove the valve springs. (Refer to 9 -
ENGINE/CYLINDER HEAD/VALVE SPRINGS -
REMOVAL)
(2) Remove the valve stem seal (Fig. 44).
INSTALLATION
(1) Install the valve stem seal squarely over the
valve guide, using the valve stem as a guide (Fig.
44). Do not force the seal against top of the valve
guide.
(2) Install the valve spring. (Refer to 9 - ENGINE/
CYLINDER HEAD/VALVE SPRINGS - INSTALLA-
TION)
ENGINE BLOCK
DESCRIPTION
The cylinder block is made of cast iron and is a
deep skirt design.
STANDARD PROCEDURE - CYLINDER BORE
HONING
(1) Used carefully, the cylinder bore resizing hone,
recommended tool C-823 or equivalent, equipped
with 220 grit stones, is the best tool for this honing
procedure. In addition to deglazing, it will reduce
taper and out-of-round as well as removing light
scuffing, scoring or scratches. Usually a few strokes
will clean up a bore and maintain the required lim-
its.
(2) Deglazing of the cylinder walls may be done
using a cylinder surfacing hone, recommended tool
C-3501 or equivalent, equipped with 280 grit stones,
if the cylinder bore is straight and round. 20±60
strokes depending on the bore condition, will be suf-
ficient to provide a satisfactory surface. Use a light
honing oil.Do not use engine or transmission oil,
mineral spirits or kerosene.Inspect cylinder walls
after each 20 strokes.
(3) Honing should be done by moving the hone up
and down fast enough to get a cross-hatch pattern.
When hone marksintersectat 40-60 degrees, the
cross hatch angle is most satisfactory for proper seat-
ing of rings (Fig. 45).
(4) A controlled hone motor speed between
200±300 RPM is necessary to obtain the proper cross-
hatch angle. The number of up and down strokes per
minute can be regulated to get the desired 40±60
degree angle. Faster up and down strokes increase
the cross-hatch angle.
(5) After honing, it is necessary that the block be
cleaned again to remove all traces of abrasive.CAUTION: Ensure all abrasives are removed from
engine parts after honing. It is recommended that a
solution of soap and hot water be used with a
brush and the parts then thoroughly dried. The bore
can be considered clean when it can be wiped
clean with a white cloth and cloth remains clean.
Oil the bores after cleaning to prevent rusting.
CLEANING
Clean cylinder block thoroughly using a suitable
cleaning solvent.
INSPECTION
ENGINE BLOCK
(1) Clean cylinder block thoroughly and check all
core hole plugs for evidence of leaking.
(2) If new core plugs are to be installed, (Refer to 9
- ENGINE - STANDARD PROCEDURE - ENGINE
CORE AND OIL GALLERY PLUGS).
(3) Examine block and cylinder bores for cracks or
fractures.
(4) Check block deck surfaces for flatness. Deck
surface must be within service limit of 0.1 mm (0.004
in.).
CYLINDER BORE
NOTE: The cylinder bores should be measured at
normal room temperature, 21ÉC (70ÉF).

the plunger and the lifter body causing the plunger
to stick in the down position. This heavy click will be
accompanied by excessive clearance between the
valve stem and rocker arm as valve closes. In either
case, lifter assembly should be removed for inspec-
tion.
REMOVAL
(1) Remove the cylinder head(s). (Refer to 9 -
ENGINE/CYLINDER HEAD - REMOVAL)
(2) Remove the yoke retainer and aligning yokes
(Fig. 73).
(3) Remove the hydraulic lifters. If necessary use
Special Tool C-4129, or equivalent to remove lifters
from bores. If lifters are to be reused, identify each
lifter to ensure installation in original location.
INSTALLATION
(1) Lubricate the lifters with engine oil.
NOTE: Position the lifter in bore with the lubrication
hole facing upward (Fig. 72).
(2) Install the hydraulic lifters with the lubrication
hole facing upward towards middle of block (Fig. 72).
Install lifters in original positions, if reused.
(3) Install lifter aligning yokes (Fig. 73).
(4) Install yoke retainer and torque screws to 12
N´m (105 in. lbs.) (Fig. 73).
(5) Install the cylinder heads. (Refer to 9 -
ENGINE/CYLINDER HEAD - INSTALLATION)
(6) Start and operate engine. Warm up to normal
operating temperature.
CAUTION: To prevent damage to valve mechanism,
engine must not be run above fast idle until allhydraulic lifters have filled with oil and have
become quiet.
PISTON & CONNECTING ROD
DESCRIPTION
The pistons are made of cast aluminum alloy and
are a strutless, short skirt design. The piston rings
consist of two compression rings and a three piece oil
ring. Piston pins connect the piston to the forged
steel connecting rods. The piston pins are a press fit
into the connecting rod.
OPERATION
The piston and connecting rod is the link between
the combustion force to the crankshaft.

STANDARD PROCEDURE
STANDARD PROCEDURE - FITTING
CONNECTING RODS
The bearing caps are not interchangeable or
reversible, and should be marked at removal to
ensure correct reassembly. The bearing shells must
be installed with the tangs inserted into the
machined grooves in the rods and caps. Install cap
with the tangs on the same side as the rod. For con-
necting rod bearing fitting (Refer to 9 - ENGINE/EN-
GINE BLOCK/CONNECTING ROD BEARINGS -
STANDARD PROCEDURE). Fit all connecting rods
on one bank until complete.
NOTE: The connecting rod cap bolts should be
examined before reuse. Bolt stretch can be checked
by holding a scale or straight edge against the
threads. If all the threads do not contact the scale
the bolt must be replaced (Fig. 74).
(1) Before installing the nuts the threads should
be oiled with engine oil.
(2) Install nuts finger tight on each bolt then alter-
nately torque each nut to assemble the cap properly.
(3) Tighten the nuts to 54 N´m PLUS 1/4 turn (40
ft. lbs. PLUS 1/4 turn).
(4) Using a feeler gauge, check connecting rod side
clearance (Fig. 75). Refer to Engine Specifications
(Refer to 9 - ENGINE - SPECIFICATIONS).
STANDARD PROCEDURE - FITTING PISTONS
The piston and cylinder wall must be clean and dry.
Piston diameter should be measured 90 degrees to pis-
ton pin at size location shown in (Fig. 76). Cylinder
bores should be measured halfway down the cylinder
bore and transverse to the engine crankshaft center line
shown in (Fig. 77). Refer to Engine Specifications (Refer
to 9 - ENGINE - SPECIFICATIONS).Pistons and cyl-
inder bores should be measured at normal room
temperature, 21ÉC (70ÉF).
REMOVAL
(1) Disconnect negative cable from battery.
(2) Remove the cylinder heads. (Refer to 9 -
ENGINE/CYLINDER HEAD - REMOVAL)
(3) Remove the oil pan. (Refer to 9 - ENGINE/LU-
BRICATION/OIL PAN - REMOVAL)
(4) Remove the top ridge of cylinder bores with a
reliable ridge reamer, if necessary, before removing
pistons from cylinder block.Be sure to keep tops
of pistons covered during this operation. Pis-
tons and connecting rods must be removed
from top of cylinder block. When removing pis-
ton and connecting rod assemblies from the
engine, rotate crankshaft so that each connect-
ing rod is centered in cylinder bore.
