Hartzell 7497 + io-360-M1B vibe?

Flying Scotsman · #1 02-04-2010, 10:19 AM

Trying to make sure that I have the right limitations, if any, on this combination:

Hartzell HC-C2YR-1BF/7497 +
Lycoming XIO-360-M1B

(i.e., the combination sold by Van's)

Hartzell says they have no information on such a combination (operating limitations for MP/RPM ranges a la the 200 HP IO-360, etc.). Closest they have is the IO-360-M1A (no limits).

Anyone have any further info here? Are there any limitations? or not?

TIA
Steve

Steve,

Speak to Les Doud at Hartzell. He arranged a letter for me from one of their Vibration Engineers confirming the IO-360-M1B + 7497 + 1x LSE PLASMA III was ok vibration wise with no restrictions.

Say, I don't suppose you could shoot me a copy of that as well? I have the exact same setup: IO-360-M1B + C2YR-1BF/F7497 + single Plasma III.

(edit) I'd be happy to host a copy on my website, if you'd like!

thanks,

it would be great if I can also get a copy of that letter. I have the exact same setup and was told there is no limitation but don't have any thing in writting.

Thanks

Hi Chaps,

Would like to be able to help straight away but the letter says the data is proprietary to Hartzell so I am not sure whether it is appropriate for me to send copies around the internet.

I have emailed Les Doud at Hartzell with a link to this thread and asked him to take a look.

Les, If you're there...
Is it ok for me to pass on copies of my letter?
Or should these folks each contact you direct?

Regards,

I called Les today but missed him (left a message). Hopefully, we'll get an answer.

Your setup is not quite the same as what I'll have...I'll be running regular ol' mags, not the Plasma stuff (and I think I've seen the letter you're talking about, which specifically references the electronic ignition).

Guys,

I'm in San Bernardino at the moment. I'll ask our Vibration Engineer as soon as practical if we can publish this somehow? It may not be until next week when I return to Piqua. Since the -M1B and Lightspeed are not certified, we cannot list it in the TCDS, only provide some sort of informational sheet at best that some authorities may or may not accept.

Hi Les, Thanks for checking in here.

Please note that there are two different setups mentioned in this thread,
-M1B + 7497 + 2x Mag
-M1B + 7497 + 1x Mag + 1x LSE PLASMA CDI

Might as well throw in the ones with 2 lightspeeds. There are a few of us too!

1 mag / 1 pmag is a very popular combo as well.

thanks
