(Noel Loveys) ________________________________ Message 1 _____________________________________ Time: 01:27:43 PM PST US From: "Noel Loveys" Subject: RE: Engines-List: Lycoming tach drive cover. Drill a hole (1/16") in the edge of the cap, through the kernelled part, if it doesn't already have one and lock wire it in place. Is there an "O" ring associated with this cap? If so make sure the hole you may have to drill is outside the "O" ring seal.
