Manifolds

Introduction
The exhaust manifolds fitted to these engines have large clearance holes for the setscrews. It is important that
these manifolds are fitted correctly.
A new three-piece exhaust manifold has been introduced for some turbocharged six cylinder engines with side
mounted turbochargers. The exhaust manifold is in three pieces to allow for expansion.
Intake manifolds fitted to engine types AR and AS, are in two pieces sealed together with a liquid joint. The
two pieces are joined together with setscrews. In service the liquid joint is replaced with a paper joint.
Caution: If a setscrew for the exhaust manifold has become loose or has to be loosened, all of the setscrews
must be loosened and then tightened. If this is not done the manifold could be damaged when it becomes hot.

To remove
1 Loosen the securing clips and remove the air intake hose.
2 Remove the pipe which is fitted between the fuelled starting aid in the intake manifold and the fuel filter.
Disconnect the electrical connection.
3 For engines fitted with a boost control device: Remove the boost control pipe which is fitted between the
intake manifold and the top of the fuel injection pump.
4 Release the intake manifold fasteners and remove the manifold from the cylinder head.
For intake manifolds fitted to engine types AR and AS: The top half of the intake manifold (A1) in production is
sealed to the bottom half (A2) with a liquid joint and fastened together by setscrews. In service the liquid joint
is replaced with a paper joint.
The top half of the manifold must be removed to obtain access to the manifold fasteners (A3), fitted inside the
manifold. These fasteners retain the bottom half of the manifold to the cylinder head.
