Servicing the Seals
MANIFOLD AND SEAL REMOVAL
1.09 Use a 10 mm hex socket to remove the
four (4) HSH screws from the inlet manifold.
1.10 Using a rubber mallet, tap the manifold to

and the manifold.
1.13 Use a flat tip screwdriver to pry the first
V-packing upward and remove.
NOTICE:
Be careful not to score the inside of
the manifold.
1.16 Inspect the manifold bore to ensure sealing
surface is smooth and free from corrosion.
1.11 Insert two (2) flat tip screwdrivers on opposite
sides to pry the manifold away from the
crankcase.
1.14 Repeat for the second V-packing, inspect both
for wear or damage.
1.17 Flip the inlet manifold over so low-pressure
seals are facing upwards.

on a flat surface with V-packing spacer bores
facing up.
1.15 Remove the female adapter and inspect for
wear or damage.
