Can't find the break-out for the up-lock actuator in the IPC - says see Fig 46... in Fig 46 .

Need cross ref's for MS28774 teflon packings .

Need alternative PNs for : S1120-363, S1120-181, S1121-389, S1121-207

Thanks!

Airpower
 

With the exception of S1121-207, Airpower has all the Cessna parts numbers in stock for $15 or less each. The S1121-207 must be made of Kriptonite, they have it in stock, but it is $129. So other than that part, the pricing seems really reasonable. Many times they list alternate MS or AN part numbers for Cessna numbers, but not for that part........

I use QWANT for searching parts..
For some reason, it is much better and faster, and usually gives me cheaper, uh hem, "less costly" parts...

Unable to find a S1121-329
Are you sure that is a good number??

AN6227B series is the cross ref for the MS28775 orings.
Aircraft spruce has them.. the whole series...
And that is enough for me for one day..
Have a great day all ya all.

Ok, now.. really, this is it for me. I have posted way to much today.
Good night

Thanks a Randy, you're far more patient than I with dealing with part searchs !


Okay, so the door actuators use standard MS28774 & MS28775, that's easy.

The Cessna PNs are only found on the up-lock / down-lock actuators :

Baby powder or foot spray
 

I'm going through the agonizing removal of the center floorboard to get to the uplock actuator to have it overhauled. In this p model they use rivets to attach the panel, what a job. This leak was easily seen. For the small almost undetectable leaks of any type of oil, I have always used a dusting of baby powder or foot spray powder. Having it good and clean before applying goes without saying, just something over the years I've come to rely on. It will draw the oils out of the crack or area applied, easily seen. Joes
