Percy, I took my old one apart to see if I could fix it, and how it worked. The gears seemed to be fine and the spring was still connected, near as I could tell, there was nothing that I could fix. Mine was spiking +- 500 rpm when I put the new one in. I bought the new one from WAG Aero and had one heck of a time getting the square drive to fit in the back of the instrument, it works fine though, and no spiking. -----Original Message----- From: Percy Wood [mailto:[EMAIL PROTECTED] Sent: Monday, December 02, 2002 2:29 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED]; [email protected] Subject: Re: [COUPERS-FLYIN] swappin' a C75 ----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- At 09:05 AM 12/2/02 -0500, [EMAIL PROTECTED] wrote: >----[Please read http://ercoupers.com/disclaimer.htm before following any >advice in this forum.]---- > > >Hi Jan: I routinely find that these old Tachometers are not correct.

(50 >rpm low, I see no problem, 200 rpm low, I change the tach) Does anybody know if the old tachometers can be repaired? Cheaper than replacement? Like dissassemble, clean, lube, and put back together? Percy, who has a real shakey one = couple hundred wiggle. ========================================================================== ==== To leave this forum go to: http://ercoupers.com/lists.htm ========================== To leave this forum go to: http://ercoupers.com/lists.htm
