Engine build-up consists of the removal of accessories and equipment from the old
engine and installing them on the new engine. Consult the Engine Maintenance Manual
for removal and replacement procedures. After all accessories and equipment have
been installed on the new engine, proceed as follows:
Consult the Engine Maintenance Manual before removing the
new engine from the shipping container.
If the old engine is being removed because of oil
contamination or the possibility of oil contamination, scrap the
following items: (a) oil cooler and (b) all oil carrying lines and
hoses.
If the old engine has oil contamination, the following items
must be sent to an appropriate maintenance facility for
disassembly and flushing to remove all contaminants or they
must be replaced: (a) over speed-governor, (b) propeller, (c)
fuel/oil heat exchanger (d) propeller governor (C.S.U.).
(NOTE: The fuel/oil heat exchanger and propeller governor
normally comes with the new engine.) Failure to comply with
the above will prove to be false economy, as the new engine
will be contaminated by old impurities.
Tag or identify all hoses, bolts, nuts, and electrical connector
plugs and note harness clamp locations for installation on the
new engine. Cap all open hoses and engine ports to prevent
contamination.
A. Remove the engine control brackets and supports from the old engine and install
on the new engine. Consult the Engine Maintenance Manual for the proper
