5.12.2 Induction Manifold
5.12.2.1 Mandatory Updates
There are no mandatory updates to the induction manifold assembly.
5.12.2.2 Optional Updates
2200 engines: Early 2200 engines had the induction manifold cast as part of the sump & were equipped
with a 32mm carburettor. It is recommended to fit a new sump & 40mm carburettor at overhaul.
3300 engines:
-
Most 3300 engines are equipped with a bolt-on induction manifold assembly similar in appearance
to the 2200 engine part shown in Figure 187 (note the shape of the diffuser used in this part
–
circled in the figure).
-
Later engines use a “Series III” bolt-on induction manifold assembly. This system incorporates two
round diffusers into the manifold body
in place of the “airfoil” shaped part shown in Figure 187. It
also uses different angles and shapes for the induction pipes themselves.
-
Current engines use an induction cast into the sump as shown in Figure 100 (right).
All of these configurations are acceptable for the 3300 engine: upgrades in this area at overhaul are
optional.
5.12.2.3 Cleaning
Disassemble and wash. Note that to remove the Loctite sealing compound it may be necessary to use
a plastic scraper and / or scouring pad.
5.12.2.4 Inspection And Repair
Visually inspect.
