Thanks for the info. Sounds right at that length. I made it with stock belts but it was a struggle. Probably change next annual or so.

I believe mine were close on the slip torque but I think I'll change to your belt this fall. Probably won't fly too many hours anyway. Thanks for the update. It helps. Bob

FYI. The Twin came out of annual once in Chicago in the early 80s. All tested well on a flight.

The next flight into IMC was memorable as BOTH alternators failed - one lost a belt and the other lost a bearing. So, in the soup with a compass. We did time and distance to the nearest VFR - thank goodness there was some as our destination only had an ADF approach and ours was dead w/o electrical power. Found ourselves within 5 miles of where we thought we should be.

We had shut everything down to conserve what little battery remained. That gave us enough to get the gear down w/o emergency procedure and land safely. Center sent the lineman out to greet us. We were very happy to call them.

Just some things you might want to consider.

As a result of that experience, we actually practice flying under the hood with the battery powered aids we have today and when we re-did the panel, we designed it so the KX155 can be a backup to the 530W, the yoke 496 is another backup, the iPad is a help and we carry paper for the departure, fuel stops and arrival points.

The Plane Power directions specify a belt change. I had the shop order two of these belts and the conversion was simple.
The specified belts are longer and, at my fbo, not a standard in-house stocked size.

PS Been very happy with the conversion.
