O-300 Recommended Overhaul Shops?

[Fearless Tower]

Well, as a continuation of my previous thread regarding the Mag failure, we pulled the accessory case apart and could not find the missing gear tooth. What we found was a TON of fine metal shavings all over the place....looks like the tooth got pulverized and now I'm looking for recommendations on overhaul shops to pull the engine apart and at least clean it up and inspect the innerds.

Any recommendations? Any ideas on what this could cost me?

I am home in Virginia now, but the airplane is stuck with an A&P IA friend in Texas (MWL).

Just in Tulsa and visited several o'Haul shops, I was impressed with Custom AirMotive, Staff has been there for many years, Water break Dyno to run engines on, Mark 9188366836

I'm planning on having my engine overhauled at Zephyr aircraft engines in Florida. They continuously win aviation consumer top shop and are highly regarded on the AOPA and Pilots of America forum.

Charlie Melot is the owner.

Their website is http://www.zephyrengines.com/homepage.html

I'm not affiliated in any way but have done some homework and spoken with them and have planned to use them when the time comes.

my .02 cents.

I see you are in Norfolk. At Winchester Airport is a Aero Engines of Winchester. I have not dealt with them but from those that have I have heard good reports. The advantage is you could deliver the engine. Have a little more control over it.

Andrew, I'm bummed to hear your engine ate a gear but look at it as an opportunity to freshen up your engine. Your plane is cherry and deserves it! Love the straight 170's and puts a smile on my face every time I see a nice clean one like yours.

Thanks Ash.....looks like I may still be in business. I found a low time O-300 available within driving distance that has everything I need (prop and mags). A LOT cheaper than overhauling my O-300 A. 96V will fly again!

Great news! One plus on the O-300-D is the 6 bolt crank and the 1C172 EM 76XX series propellers that have a thinner, updated airfoil which is supposedly more efficient than the 1A170 DM76XX.

What prop pitch/type is the engine coming with?

The 6-bolt is good to have IF you ever have to replace it - more available, but you can get the the same prop for the 8-bolt.

Not exactly the same prop... The MDM has the same blade profile, but the EM hub is smaller/lighter thereby saving weight,...but otherwise....

I switched from the DM to the MDM and honestly couldn't notice a difference.

When you say you couldn't notice a difference....I presume you mean a difference in performance. ??

With the crude instrumentation of these airplanes (coupled with the fact you likely had no practical "control" with which to compare... I'm not surprised you couldn't detect any difference.
The engine noticed a difference, however. Less mass to swing is easier on your engine. The thinner blades made a difference in weight. (Try swinging a couple pounds of aluminum placed 2-feet out on a stick around at 2500 RPM and see how it feels. IF you don't have a torn rotator-cuff previously...you soon will.)

I kind of thought that was implied since we were talking about the two different cranks. I was only referring to the parts that stick out from behind the spinner.
