I think Vic's guess of what happened is pretty close. In my conversation with MT he mentioned sometime in 2014 they made a change in manufacturing. The flyweights were welded on prior to 2014. They increased the material thickness and pinned one side and welded the other on the models sometime during 2014. He said the actual fix shouldn't take more than 1.5 hours. They only have 3 sets of the new parts and are waiting on more from Germany.

SB Cost?
Anyone know if there is a cost for the SB?

Dan, you are correct, although my prop over speed and P-860-3 governor failure was the result of the bushing seizure and SB 27.

MT governor failure
Guys, after realizing my governor self destructed which was found by placing it on a test stand at Tiffin Aire (Tiffin, 0H), MT did send me a new
p-860-3 with a manufactured date in 2016. I have since completed my 25 hour Transport Canada test period. When I recover from shoulder surgery and the shock of an almost $11k repair bill to my IO-540, I will be pulling that MT governor off and replacing it with a Hartzell governor. If anyone wants a cheap slightly used governor let me know. Rick #40956 Southampton, Ont |

Ratio
Just another curve ball in this governor issue. Our io540 is a wide deck with narrow deck drive gear ratio so 860-3 is correct one for our engine. We were told that the ratio difference is related to Io540 260 HP/vrs 300hp wide deck version but waiting for Aerosport to confirm. Just Fyi.
