Pipe Joint Compound
• Pipe joint compound is a pliable sealer that does not comp letely harden. This type of sealer is used where two non-
rigid parts (such as pressed steel and ma chined surfaces) are assembled together.
• Do not use pipe joint compound in areas where extreme temperatures are expected. These areas include the
exhaust manifold, head gasket, or other surfaces where gasket eliminator is specified.
• Follow all safety recommendations and di rections that are on the container.
• To remove the sealant or the gasket mate rial, refer to Replacing Engine Gaskets.
• Apply the pipe joint compound to a clean surface. Use a bead size or quantity as specified in the procedure. Run
the bead to the inside of any bolt holes. Do not allow the s ealer to enter any blind threaded holes as it may prevent
the bolt from clamping correctly or caus e component damage when the bolt is tightened.
• Apply a continuous bead of pipe joint compound to one seali ng surface. Sealing surfaces to be resealed must be
clean and dry.
• Tighten the bolts to the correct torque specification. Do not over-tighten.
Separating Parts
CAUTION
Many internal engine components will
develop specific wear patterns on their
friction surfaces. When disassembling the
engine, internal components must be
separated, marked and organised in a way to
ensure reinstallation in their original location
and position.
Separate, mark, or organise the following components:
• Piston and the piston pin.
• Piston to the specific cylinder bore.
• Piston rings to the specific piston.
• Connecting rod to the crankshaft journal.
• Connecting rod to the bearing cap.
• Crankshaft main and connecting rod bearings.
• Camshaft and rocker arms.
• Rocker arms and stationary hydraulic lash adjusters to cylinder head location.
• Valve to the valve guide.
• Valve spring and shim to the cylinder head location.
• Engine block main bearing cap location and direction.
• Oil pump drive and driven gears.
Tools and Equipment
Special tools are listed and illustrated throughout this Section with a complete listing at the end, refer to 7 Special Tools.
These tools (or their equivalents) are specially designed to quickly and safely accomplish the operations for which they
are intended. The use of these special tools will also minimise possible damage to engine components. Some precision
measuring tools are required for inspec tion of certain critical components. A commercially available torque wrench and
torque angle wrench, Tool No. EN-7115 are required for the correct tightening of various fasteners.
To correctly 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 organised.
• An adequate set of hand tools.
• Approved engine repair stand.
• An approved engine lifting device that will adequatel y support the weight of the components.

Starting System – V6 Page 6D1-2–3

1 General Information
All HFV6 engines are fitted with a Mitsubishi starter motor. This consists of a solenoid switch on a DC motor. The motor
has permanent magnet excitation, which has the advantage of low weight a with high output torque and is visually
identifiable by the absence of pole-shoe retaining screws.
The starter motor does not have field coil windings or pole shoes. These parts have been replaced by six permanent
magnets that are held in the pole housing by clips. The positive brushes are now part of the brush plate assembly.
The solenoid switch is the only component of the starter motor assembly that is serviced separately. If any other parts
require replacement, the starter motor must be replaced.
