JumpPilot Dave · #1 11-26-2009, 09:32 PM

I would like to drive a B&C alternator from what is normally used for the prop governor drive pad..My installation wont allow the use of the normal vacuum pump drive .

Anybody have one laying around or the Lycoming part# ??? or know how to find out?

Thanks dave

Dave,
I'm not sure exactly what you need a part number for? Do you want a part number for a specialized adapter pad, to mount a vacuum pump at the prop governor location? [most likely] The part number of the prop governor pad? [This I have]
Might you know what model of Lycoming this item was used on?

Hi Charlie,

I'm trying to put an alternator on 2 different planes.
1.IO-320 e2a on the governor pad.
2.AEIO-540 D4A5 on the governor pad
I don't know what plane drove the vacuum pump off of the governor pad!
The part I'm looking for will drive a vacuum pump from the governor pad on the lower back of the engine.(But I will put an SD-8 alternator there instead)
Thanks,Dave
