Service manual

• Do not overtighten the fasteners.
− Apply the gasket eliminator sealant evenly to
get a uniform thickness of the gasket
eliminator sealant on the sealing surface.
− Tighten the fasteners in sequence, if
specified, and to the proper torque
specifications.
− After properly tightening the fasteners,
remove the excess gasket eliminator sealant
from the outside of the joint.
Anaerobic Type Threadlock Sealant
Anaerobic type threadlock sealant cures in the
absence of air. This type of sealant is used for
threadlocking and sealing of bolts, fittings, nuts, and
studs. This type of sealant cures only when confined
between 2 close fitting metal surfaces.
Use the following information when using threadlock
sealant:
• Always follow all safety recommendations and
directions that are on the threadlock sealant
container.
• The threaded surfaces to be sealed must be clean
and dry.
• Apply the threadlock sealant as specified on the
threadlock sealant container.
Important:
• Fasteners that are partially torqued and then the
threadlock sealant allowed to cure more than
five minutes, may result in incorrect clamp load of
assembled components.
• Do not overtighten the fasteners.
• Tighten the fasteners in sequence, if specified,
and to the proper torque specifications.
Anaerobic Type Pipe Sealant
Anaerobic type pipe sealant cures in the absence of
air and remains pliable when cured. This type of
sealant is used where 2 parts are assembled together
and require a leak proof joint.
Use the following information when using pipe sealant:
• Do not use pipe sealant in areas where extreme
temperatures are expected. These areas
include:
− The exhaust manifold
− The head gasket
− Surfaces where a different sealant is
specified
• Always follow all the safety recommendations and
the directions that are on the pipe sealant
container.
• The surfaces to be sealed must be clean and dry.
• Use a pipe sealant bead of the size or quantity
as specified in the service procedure.
Notice: SIO-ID = 768432 Do not allow the pipe sealant
to enter a blind hole. The pipe sealant may prevent
the fastener from achieving proper clamp load, cause
component damage when the fastener is tightened,
or lead to component failure.
• Apply the pipe sealant bead to the inside of any
bolt hole areas.
• Apply a continuous bead of pipe sealant to
1 sealing surface.
Important: Do not overtighten the fasteners.
• Tighten the fasteners in sequence, if specified,
and to the proper torque specifications.
Separating Parts
SIE-ID = 194497
Important: Many internal engine components will
develop specific wear patterns on their friction
surfaces.
When disassembling the engine, internal components
MUST be separated, marked and organized in a
way to ensure reinstallation to original location and
position.
Mark or identify the following components:
• Piston and the piston pin
• Piston to the specific cylinder bore
• Piston rings to the specific cylinder bore
• Connecting rod to the crankshaft journal
• Connecting rod to connecting rod cap
• Crankshaft bearings and connecting rod bearings
• Engine camshaft and valve lifters
• Valve lifters and valve rocker arms
• Valve to the valve guide
• Valve spring to cylinder head location
• Engine block bearing cap location and direction
• Oil pump drive and driven gears
Tools and Equipment
SIE-ID = 507215
Special tools are listed and illustrated throughout this
section with a complete listing at the end of the
section. The tools (or the equivalents) are specially
designed to quickly and safely accomplish the
operations for which the tools are intended. The use
of special tools will also minimize possible damage
to engine components. Some precision measuring
tools are required for inspection of certain critical
components. Torque wrenches and a torque angle
meter are necessary for the proper tightening of
various fasteners.
To properly service the engine assembly, the following
items should be readily available:
• Approved eye protection and safety gloves
• A clean, well-lit, work area
• A suitable parts cleaning tank
• A compressed air supply
• Trays or storage containers to keep parts and
fasteners organized
• An adequate set of hand tools
• Approved engine repair stand
• An approved engine lifting device that will
adequately support the weight of the components
