INTRODUCTION
Safety rules - Ecology and the environment
Soil, air, and water quality is important for all industries and life in general. When legislation does not yet rule the
treatment of some of the substances that advanced technology requires, sound judgment should govern the use and
disposal of products of a chemical and petrochemical nature.
Familiarize yourself with the relative legislation applicable to your country, and make sure that you understand this
legislation. Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, anti-freeze,
cleaning agents, etc., with regard to the effect of these substances on man and nature and how to safely store, use,
and dispose of these substances.
Helpful hints
• Avoid the use of cans or other inappropriate pressurized fuel delivery systems to fill tanks. Such delivery systems
may cause considerable spillage.
• In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of these products contain substances
that may be harmful to your health.
• Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems.
• Avoid spillage when you drain fluids such as used engine coolant mixtures, engine oil, hydraulic fluid, brake fluid,
etc. Do not mix drained brake fluids or fuels with lubricants. Store all drained fluids safely until you can dispose of
the fluids in a proper way that complies with all local legislation and available resources.
• Do not allow coolant mixtures to get into the soil. Collect and dispose of coolant mixtures properly.
• The air-conditioning system contains gases that should not be released into the atmosphere. Consult an air-condi-
tioning specialist or use a special extractor to recharge the system properly.
• Repair any leaks or defects in the engine cooling system or hydraulic system immediately.
• Do not increase the pressure in a pressurized circuit as this may lead to a component failure.
• Protect hoses during welding. Penetrating weld splatter may burn a hole or weaken hoses, allowing the loss of oils,
coolant, etc.
Battery recycling
Batteries and electric accumulators contain several substances that can have a harmful
effect on the environment if the batteries are not properly recycled after use. Improper
disposal of batteries can contaminate the soil, groundwater, and waterways. NEW
HOLLAND strongly recommends that you return all used batteries to a NEW HOLLAND
dealer, who will dispose of the used batteries or recycle the used batteries properly. In
some countries, this is a legal requirement.
Mandatory battery recycling
NOTE: The following requirements are mandatory in Brazil.
Batteries are made of lead plates and a sulfuric acid solution. Because batteries contain heavy metals such as lead,
CONAMA Resolution 401/2008 requires you to return all used batteries to the battery dealer when you replace any
batteries. Do not dispose of batteries in your household garbage.
Points of sale are obliged to:
• Accept the return of your used batteries
• Store the returned batteries in a suitable location
• Send the returned batteries to the battery manufacturer for recycling

Engine - Cylinder heads
Cylinder head - Static description
Cylinder Head and Valve Train Components
The cylinder head incorporates the valve assemblies, rocker arms, rocker shaft, push rods, and lifters. A swirl cham-
ber located between the injector assembly and the main combustion chamber of the cylinders provides improved
starting and greater fuel efficiency. Initial combustion starts in the precombustion chamber and as the expansion oc-
curs a strong swirl pattern is created in the main combustion chamber for more complete combustion of the air-fuel
mixture. The air intake manifold is separate from the cast aluminum valve cover on all these engines. The exhaust
manifold is bolted on the left-hand side of the cylinder head on each of the models. Cylinder heads have integral valve
guides. Standard size valves only are used.
The cylinder block assembly contains the pistons, connecting rods, crankshaft, timing gears, and engine oil pump.
The crankshaft is supported on five main bearings. The front bearing is positioned in a bore in front of the block. The
other bearings are split liners located in holders bolted to the block. The camshaft is supported on four ball bearings
located in the block.

Valve cover - Install
Prior operation:
Valve drive and gears - Clearance (Valves) (10.106).
1. Install a new gasket (1) and position the valve cover (2)
over the rocker arms.
2. Install the valve cover retaining bolts (3), and tighten to
12 - 16 N·m (9 - 19 lb ft).
3. Install and tighten the seal washer (4), and cap nuts (5).

Cylinder head - Compression test
Compression test is performed through the glow plug ports. The test adapter tool (1), is equipped with quick coupler
ends for easy installation of the hose and gauge.
The procedures to perform a compression test are as follows:
1. Remove the wire lead from the fuel injection pump so-
lenoid.
2. Remove the glow plug electrical wire and wire connec-
tor from top of the glow plugs.
SECT10C01PG17_1 1
3. Remove all of the glow plugs.
NOTE: Be sure all the glow plugs are removed before starting the compression tests.
4. Install the adapter Tool No. FNH00120 , hose and
gauge assembly OEM1074 (2), in each port and crank
the engine until pressure stabilizes. The gauge should
read 2944 kPa (427 psi) ) plus or minus 345 kPa
(50 psi) .
SECT10C01PG17_2 2
NOTE: It may be necessary to remove some injector fuel lines to install the adapter tool.
NOTE: There should not be more than 345 kPa (50 psi) variation between the cylinders.
5. When all cylinders have been tested, reinstall the glow
plugs and electrical connections.

Cylinder head - Remove
Prior operation:
Rocker Arm Shaft and Support Bracket - Remove; See: “Engine Disassemble”..
1. Remove the valve stem caps (1), and push rods (2).
2. To remove the cylinder head, remove the cylinder head
bolts (3), by alternately loosening a half turn at a time
to prevent warping the head.
NOTE: Keep all valve components in separately marked
containers for reassembly in their original location.

Cylinder head - Inspect
Prior operation:
Crankcase gears - Remove - with Camshaft (10.114).
1. Disassembly
1. Clean the cylinder head and remove any carbon
deposits from around the valve heads.
2. Use a valve spring compressor and remove the
valve spring retainer locks (1), spring (2), and
spring retainer (3), from each valve (4).
3. Remove the valves and place the valve compo-
nents together in separately marked containers for
reassembly in their original position.
20093369 1
2. Inspection and Repair
1. Clean all carbon deposits from the combustion
chamber and valve ports using a wire brush and
scraper.
2. Clean all dirt and residue from the gasket surface
using care not to scratch or nick the machined sur-

3. Clean the cylinder head in solvent and air dry.
4. Inspect the head for cracks or damage in the fol-
lowing areas:
• Valve ports
• Valve seats (2).
• Prechamber (3).
• External cracks in the water jackets (1)..
5. Inspect the gasket surfaces for scratches or nicks,
which could cause leakage.
6. Examine the core hole plugs for rust or signs of
leakage. If a plug shows signs of damaging rust or
leakage, replace all plugs in the head.
7. Inspect the prechamber for carbon deposits and
looseness. Remove any carbon deposits found.
If prechamber is found to be loose, cylinder head
may be warped.

Cylinder head - Replace (Gasket)
During assembly, the ultimate engine compression ratio is established by the thickness of the head gasket used. For
service replacement, head gaskets of different thickness are available. The correct head gasket must be selected
based upon the amount the piston protrudes above the face of the block when at top dead center. The correct head
gasket usage is determined as follows:
Head Gasket Selection
1. Position each of the pistons at top dead center and, us-
ing a dial indicator, determine the distance each piston
projects above the face of the block.
NOTE: Measure each of the pistons while holding a slight
down pressure on the piston. Use the dimension taken
from the cylinder which has the greatest projection and se-
lect a head gasket as indicated in the following chart.
NOTE: The variation in the amount of protrusion among all
pistons must be within 0.1 mm (0.004 in).

Prior operation:
Crankcase gears - Inspect (Camshaft) (10.114).
1. Inspect the ring gear for cracked, broken, chipped, or
worn gear teeth. If found damaged, replace the ring
