Servicing the Seals
1.19 Support the manifold from underneath. Using
a rubber mallet, tap the manifold to separate
from the crankcase and remove completely.
1.22 Inspect the manifold bores to ensure sealing
surfaces are smooth and free from corrosion.
1.25 If the low-pressure seal adapters stay on the
plungers, wipe plungers clean and apply a
light oil.
1.20 Place the inlet manifold on a flat surface with
the V-packing cylinder bores facing upwards.
1.23 Flip the manifold over so the low-pressure
seal adapters are facing upwards.
1.26 Rotate the crankshaft with an adjustable
wrench to create separation between the
low-pressure seal adapters and the seal
retainers.
