10 Before First Start
Expel inhibiting oil from cylinders and pressure up (wind engine on starter until a the oil pressure gauge
shows a reading) before first start.
Ensure correct run-in type oil is used for the first 25
– 30 hours to ensure proper ring bedding-in.
Once past the initial 25-30 hours, ensure the oil used meets the specifications given above.
Oil coolers are mandatory unless operating in very cold ambient temperatures. Refer to Oil Cooling section
above for allowable oil operating temperature ranges.
Do not overfill the engine
– this may result in high oil temperatures.
Check for contact of engine, cooler or ducts on cowl. Any contact will cause excessive vibration & if the oil
cooler is rubbing it will eventually fail & leak.
11 Auxiliary Units
11.1
Vacuum Pump
For the installation of an artificial horizon and/or a direction gyro a vacuum pump is necessary. A Tempest
212CW (or equivalent) vacuum pump can be fitted to the alternator mounting plate and directly coupled to
the crankshaft. The drive pad is dry.
The pad and spline are SAE Standard.
For later engines (S/No. 1522 and onwards) the vacuum pump drive spline is an option extra not included
with the standard engine
– it must be ordered separately.
