Operating medium: Heavy fuel and distillate fuel
Inspection:
Exhaust manifolds must be examined for leakages after 7,500 h
Maintenance:
Remove and clean exhaust manifold after 30,000 h
Auxiliary material:
High temperature-thread paste “Dag S-5080” *
* or a product of equal standard
Note:
Check also the exhaust piping after the turbocharger when doing the work on the exhaust
manifold.
If excessive vibrations and noises occur in the exhaust-gas turbine, the flanged connection
on the exhaust pipe behind the turbine must be unscrewed and examined for pipe tension.
To safeguard the expansion joints these must not be subjected to bending or radial forces
on removal and fitting. A small preload (expansion), however, is necessary in axial direc-
tion when installing (about 3mm).
Fit all screws with high temperature-thread paste “Dag S-5080” to avoid sticking due to
heat.
Sequence of operations:
1. Inspection
1.1 Remove the covering from the exhaust manifold.
1.2 Check all bolts for tightness.
1.3 Carry out a visual inspection at the flanged connections and expansion joints (inspection
must be carried out with the engine running).
