1.4 Fit the covering.
2. Maintenance
2.1 Remove covering and carry out inspections according to 1.3. Mark the mounting position of the
expansion joints and pipes.
2.2 Remove the exhaust manifold.
2.2.1 Loosen the flanged connections first at the expansion joint (Fig. 1/1), then at the cylinder head (2)
and remove the pipe.
2.3 Clean the inside of the exhaust manifolds and check for cracks.
2.4 Check the expansion joints and replace them if necessary.
2.5 Fit the exhaust manifolds with new gaskets in reverse order and observe the markings.
2.6 Coat the thread and screw contact surface of the screws with “Dag S-5080”. Screw in the screws
with resilient sleeves and tighten on alternate sides in two stages with a
torque of 60 Nm and 110 Nm.
2.7 Fit the expansion joints after precise adjustment of the pipes (direction of flow marked with arrow).
2.8 Fit the covering.
NOTE
Soot and soot deposits indicate a leak of the system. Renew the gaskets if no cracks
in the pipes or slack bolts are the cause of the leak. Replace expansion joints that
have cracks in the bellows. On assembly pay attention to the direction of flow
(arrow on the flange).
