Engine - Static description
The S8000 is a 4 cylinder turbo charged and after cool diesel engine.
It features a cross flow cylinder head, with the inlet and exhaust manifolds on opposite sides of the cylinder head.
The fuel and air combustion process, takes place in the specially designed bowel in the crown of the pistons.
Cylinder head assembly
The cylinder head incorporates valves and springs, with the valve rocker arm shaft assembly bolted to the cylinder
block through the cylinder head.
Cylinder head retaining bolts are evenly spaced with a six-point pattern around each cylinder, this ensures an even
clamping load across the cylinder head.
The intake and exhaust manifolds are bolted to the head, the intake manifold is mounted on the right side of the
engine, with the diesel injectors mounted outside the rocker cover.
The exhaust manifold is mounted on the left side of the engine.
Water outlet connections and thermostat being attached to the front of the cylinder block directly behind the radiator
valve guides are inserted into the cylinder head, and replaceable.
Special replaceable cast alloy valve seats are pressed into each valve port during manufacturing.
No oversize valve seats on guides are available. All valves are fitted with positive value rotators, valve clearance is
maintained by adjustment of the self locking adjusting screw, mounted in each of the rocker arms.
Camshaft assembly
The camshaft runs in 3 replaceable bushes.
The camshaft drive gear is in mesh with and driven by the camshaft idler gear which is driven by the crankshaft timing
gear.
Camshaft end thrust is controlled by a thrust plate bolted to the block, and located between the camshaft gear and
the front camshaft journal.
Cylinder block assembly
The cylinder block is an alloy cast iron with deep cylinder skirts & water jackets for cooling the cylinders.
The cylinder bores are machined integral with the cylinder block, during the manufacturing process.
Cylinders are in line, vertical and numbered 1 to 4 from radiator to the engine rear.
The oil sump, which is attached to the bottom of the cylinder block, is the reservoir for the engine oil lubrication system.
A cast iron engine front cover and front plate is attached to the front of the engine and covers all of the timing gear
assembly.
Crankshaft assembly
The crankshaft is supported in the cylinder block by 5 main bearings.
The crankshaft is manufactured from steel with machined finished crank webs. End thrust is controlled by a thrust
bearing incorporated in the center main bearing of the crankshaft.
Connecting rods
Connecting rods “wedge” shaped at the small end has been designed to reduce the reciprocating weight at the piston
end.

Engine - Install
If applicable, remove caps and plugs from previously
disconnected hoses and fittings. Remove identification
tags after making the hose and wire connections.
NOTE: The photos in this procedure may be different from
your machine and are for reference only.
1. Position the engine in the machine.
NOTICE: Make sure that the flex plate/converter assembly
stays in place on the transmission.
PTIL14TLB0126AA 1
2. Install and tighten the flat washers and cap screws se-
curing the transmission to the engine.
Tighten cap screws to a torque of 52 – 57 N·m (38
– 42 lb ft).
Install and tighten the front engine mounting bolts, flat
washers, and nuts.
Tighten the self-locking nuts to a torque of 90 –
100 N·m (66 – 74 lb ft).
3. Disconnect the lifting equipment from the lifting eyes on
the engine.
PTIL13TLB0730AA 2
4. Tighten the cap screws through the access in the fly-
wheel housing (1) and fasten the flywheel to the flex
plate. Tighten cap screws to a torque of 52 – 57 N·m
(38 – 42 lb ft) when fixing the torque converter.
5. Install the access cover to the bell housing.
Tighten it to a torque value of 52 – 57 N·m (38 –
42 lb ft).
6. Install the starter onto the engine.
Tighten it to a torque value of 40 N·m (29 lb ft).
Refer to Engine starter - Install (55.201).

Installation of new sleeves
1. Preparation for fitting new sleeves:
• After removal of the old sleeves, the parent bore
must be thoroughly cleaned both in the top recess
off the sleeve flange and in the parent bore itself.
• A check must be made to ensure that the whole ar-
eas of contact with the sleeves in the cylinder block
are free from burrs, corrosion or damage. Remove
any burrs present.
• Check engine block bore quality and if necessary
restore to 106.850 – 106.900 mm (4.207 – 4.209 in).
• Check if cylinder liner outer diameter is 107.020 –
107.050 mm (4.213 – 4.215 in). PTIL13TLB0826AA 4
NOTE: The cylinder liners are delivered as spare parts with
an over dimension outer diameter of 0.200 mm (0.008 in).
• Ensure that the sleeve is thoroughly clean before
fitting. If cleaning fluid is used to wash the sleeve, it
is IMPORTANT: that the sleeve be thoroughly dried
and well oiled before fitting.
• Throughout the whole operation, extreme cleanli-
ness is essential as the entry of the smallest parti-
cle or other foreign matter is sufficient to cause local
distortion of the sleeve bore.
2. Lubricate the outside diameter of the sleeves with clean
oil using spray. The use of brush is not recommended.
3. Press a new sleeve ( 0.2 mm (0.008 in) oversize if nec-
essary) from the top of the block as below.
• set the liner on the crankcase and start force
fitting. After force fitting 70 – 90 mm (2.756 –
3.543 in). check that the load is higher than 5000 N
(1124.04 lb) and lower than 23000 N (5170.6 lb).
Continue force fitting stop for 5 min. with a setting
load of above 50000 N (11240.4 lb).
• Ensure contact between edge and crank case with
a settling blow. After inserting, the liners must be
bored and surface-ground. Cylinder liners are de-
livered as spare parts with an inner diameter slightly
below nominal diameter in order to be able to correct
possible deformation appearing during mounting.
4. Skim the block face, and top of sleeves to achieve re-
quired flatness.
5. A chamfer in the internal diameter at the top of sleeve
to 30°, 0.500 mm (0.020 in) should be maintained, to
prevent piston damage on re-assembly.

7. Loosen all the bolts (1) securing front cover and bolts
(2) on oil sump.
8. Take care to loosen the bolt below the fuel injection
pump progressively to remove the cover.
ATTENTION: Do not pull the cover out without loosening
the bolt. The cover may get damaged and need replace-
ment.
9. Remove front cover, taking care of front oil seal and oil
sump gasket.
PTIL13TLB0784AB 5
Timing gear removal
NOTE: The crankshaft timing gear cannot be removed
without removing crankshaft from the engine. For crank-
shaft removal procedure refer to Crankshaft - Remove
(10.103).
1. Before removing the timing gear use a dial indicator on
feeler gauge to measure the backlash between each
set of gears.
2. Rotate the gears and check the backlash at four equal
points on the gears. Renew if the backlash exceeds
0.16 mm (0.01 in).

Idler gear
3. Remove circlip and spacer (1) and idler gear (2) from
the hub.

mosphere and all parts used should be clean and free
from dirt and other impurities.
2. If load markings or wear are observed on journal peg
diameter, needle rollers or inner diameter of bearing
races of dismantled universal joint , the entire univer-
sal joint is to be replaced, because new Journal used
with old bearing race assemblies or new bearing as-
semblies used with old journal will wear more rapidly
making another replacement necessary in a short time.

soft nosed drift (which is slightly smaller than the out-
side diameter of bearing race assembly), tap the bear-
ing race assembly into position by a soft hammer taking
care to avoid accidental spillage of needle rollers (see
