Rudder Bearings

[Dennis]

Hi All, I'm Looking for a reasonably priced upper and center rudder bearings Fafnir part number SIK-5 Ref. IPC fig. 15 item 20 for my 1953 170B s/n 26035. Cessna wants over $270.00 and thats a big OUCH. Most other airframe bearings are in the $30 to $60 range. Any help would be greatly appreciated. Happy Flying Dennis

If your need is simply a Fafnir bearing and is not part of a needed whole assembly, try any bearing house. It has been my experience that bearing numbers are common internationally. I know from experience that aircraft wheel bearings are a lot cheaper from a bearing house than any aircraft parts place. Simply use the international bearing part number.

Thanks all for the help and offers. I'm still looking for 2 bearings and if I can't find them I'll be getting back to you. Regards, Dennis

Have you tried searching for them using the part number S1K5? Did the trick for me.

[Dennis]

Simon , I did find S1K-5, but this number, if represented and stocked as S1K5 or -5 is an incorrect number. I have received 3 different bearings under this number. One was the actual bearing P/N S1K5 and is not the bearing Cessna uses. It looked very different and not meant for the rudder application. The others were completely different and would not fit. Also The actual S1K5 is not superseded to Y120 like the Fafnir SIK-5 is. Simon, if you received the correct bearing congratulations, and where did you get them? Best Regards, Dennis

Dennis, interesting. I went through the same pain you are experiencing trying to find replacement bearings for the rudder. In the parts manual it looks like it says Fafnir SIK5. I finally found a Fafnir S1K5 and that's the one that fits. There is no dash number involved. I got mine from KAMAN Industries in Tacoma, WA. They are a industrial supply place.
253-383-2723. Hope that helps.

Dennis, I will look tonight, I purchased two of those this summer when I replaced my bearings during annual. I believe Simon helped me out to find the place in WA as well.

I just ran across this on the web, says they're for the 180 series, but might want to cross reference the p/n's

After reading this thread I looked at my rudder bearings and found that they were frozen. I don't know how one could tell if the bearing was frozen except by removing the rudder and physically try and rotate the bearing. The pillow block that the bearing sits in allows for water to pool above the bearing. It's no surprise that after 50 years these bearings are frozen, even though they are sealed bearings. After soaking the bearings in Triflow I was able to get them to rotate again. Next I squeezed some grease in there with a bearing regreaser (p/n 10650-4) I bought from Aircraft Spruce. http://www.aircraftspruce.com/catalog/a ... reaser.php I think one could regrease these bearings without removing the pillow block from the aircraft but they are not difficult to remove and attach as there are nutplates used to fasten the top block.


If one goes to all the trouble of removing the rudder to regrease the top two bearings it would be worth checking the bottom bushing for wear as well. See this thread from the c-120-140 website: http://www.cessna120-140.org/forum/view ... er+bushing. I have not checked but I imagine the 120-140 lower bushing is similar to the one on the 170.
