AIRCRAFT MAINTENANCE MANUAL
** CAUTION **
If the old engine is being removed because of oil
contamination or of 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) overspeed-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.
* NOTE *
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 torque values.
