Cleared for Takeoff
I need to get a serviceable P/N 72970 vacuum pump drive gear for a 4-cylinder Lycoming.
I have a P/N 72974 gear (for the 6-cylinder Lyc) in trade if you need one. The rebuild shop (from back in 2005, can't really go after them at this point) put the wrong gear in the engine for the previous owner. It works fine for a vacuum pump but won't work with the standby alternator I'm putting on instead. The yellow tag for the part shows the correct part number (72970) but the 72974 was actually installed - which means I don't have a yellow tag to go with the 72974 I have currently. It would have to be sent out for inspection. It has 105 hours on it right now and appears brand new.
