Corky,In 50(+) years of messing around with A 65-8 Continentals, I have never seen aright hand thread on the tachometer drive; they were always a left hand threadindicated by an arrow.Possibly the threads are corroded, making it difficult to break loose. Carefullyheating the rear case (I think it may be a magnesium alloy casting) and chillingthe tach drive adapter should help. Also, a penetrating oil might assistyou. Good luck!Graham Hansen (Pietenpol CF-AUN in sunny Alberta)________________________________________________________________________________
