Inspection
When the cylinder head is due for servicing (job
01.08.01), inspect the manifold for leaks and conta-
mination inside, see also job card 06.01.03. If heavy
deposits of soot are inside, remove and clean mani-
fold.
Job:
Check manifold for leaks. Leaks due to cracks or
slack bolting are usually indicated by black discolou-
ring or carbon black/soot deposits at the ventilation
slots of the legging. Remove part of legging involved
for sealing/tightening up leaks and replacing gas-
kets, expansion joints or manifold sections. Check
that all bolts are tight.
Where the entire legging has been removed, be sure
to refit all cover plates, especially the strip covering
the ventilation slot at the top. Failing this, operating
media (fuel or oil) may find ingress into the legging, e.
g. from leaks of adjacent piping.
If the entire exhaust manifold has been removed, it is
necessary when re-assembling to observe correct
allocation of individual cylinders to the manifold sec-
tions, as shown in Fig. 2 and 3.
When refitting expansion compensators, ob-
serve the direction of flow. The bead-over of
the inner pipe and the wide overlap of the
flange must be on the flow approach side (see
Fig. 1).
When reassembling the exhaust manifold, be
sure to use the right, partly heat-resistant
bolts and nuts, as listed in the spare parts
book.
