Hello Everyone,
We just want to clarify a couple of things about our 300 Series and 330 Series C/S propellers and hub mounting drive lug configuration.
First, the easiest one, all Whirlwind C/S propellers have the standard drive lug configuration (length of drive lug) as called out for Lycoming engines configured for C/S propellers. This standard was set by Lycoming many decades ago. McCauley, Hartzell, MT or any C/S propeller interface to the crankshaft is the same for all Lycoming engines with the exception of 320 vs 360 (5/8 drive lugs 7/16 studs vs ¾ drive lugs and ½ studs- respectively).
Below is a basic overview for our 300 Series and 330 Series of Constant Speed propellers:
-The 300 Series propeller is a light weight and efficient propeller with a 3-blade constant speed system designed for 4-Cylinder Lycoming, non-counterweighted engines (0320-160HP and 0360-180HP), straight valve 0540-260HP, as well as counter weighted angle valve IO-360-IO390 engines. There are some compression ratio limitations with the 300 series propellers.
-The 330 Series 2-Blade propeller has the same 4-Cylinder Lycoming engine applications as the 300 series propellers.
-The 330 Series 3-Blade propeller is basically can go with all the engines already mentioned as well as everything else. Meaning, all the non-counterweighted angle valve IO-360 and all Lycoming IO-540’s through IO-580’s engines. No compression or ignition restrictions with these propellers.
Attached are 300 and 330 propeller application data sheets that go in more detail than the general overview mentioned.
Best regards,
