Slick Magnetos 500 Hours Inspection

For you Continental 0-200 owners, I am interested in your thoughts on Magneto 500 Hour inspections.

My aircraft has over 500 hours on my Slick Mags. A 500 hour inspection at a reputable Magneto shop runs a minimum of $375.00 each,  if the coils test good. If a coil is shot add another $250.00

 The 500 hour inspection includes new points, bearings and seals.

My mags are fine right now, and I am wondering if i should leave them as they are and try to get as many hours as I can out of them, and than get the overhauled/inspected when they start causing problems, or upgrade to a Pmag electronic replacement for at least one side. ($1700.00 per side) 

 I would not want to trade in my 500 hours mags for a rebuilt mag that has 5000 hours on them if you know what I mean. Trade in Mags usually run about $800-$900.00 each.

 So tell me what your thoughts and experiences are, I never had a Mag overhauled or even inspected in my 28 years of flying and owning aircraft.

Thanks for you input Chris,

 I'm not sure I would have any specialized tools that may be required to do the service.

Have you ever done the job?

Good to know; I thought these were non-servicable except by a shop like Kelly Aerospace. Slow-rolling my O-200, but I have one slick with 100 hrs on it, but the other has about 5-600; was going to send that in, but I may just do it myself. Thanks, Crhis;

The coils don’t usually fail but the points an distribution gear should be replaced. They’re usually very worn on slicks. I have even seen the carbon pickup cut a hole through the tab on the coil. I guess my point is you need to pop the caps an look at the 500 hr.  As far as internally timing a mag I can say slicks are the easiest to time, but I would advise you to time them with a experienced A&P your first go around.
