Connecting Link Assembly

[Ron Spiker]

Does anyone know what company makes, or where I can get the connecting link assembly for the tail rotor, part number 325-4, figure 16-7 in the parts manual?

Ron,
I think there is an old style and new style. If I am not mistaken, they are different lengths and are not interchangeable.
I doubt the manufacturer of the new style will have any info on the old style.
Does Gary or Harold not have any?
That guy from England that had all the parts on Ebay a couple of years ago had some. He's in the Resources/Parts listing.
If I remember right, Dave Matthews has a pair of brand new old style ones in a little bin of goodies at his house. He's the guy that owns Vohs' ship in Chattanooga. He's on the forum here. HELISCAN
Is yours stripped, or cracked, or is the bearings all that's bad?
Those bearings are an off-the-shelf item, but not for aviation stuff of course.

Yes, there are two different lengths. The part number I listed are the 2.5" ones. I don't know whether this is the old or new, but if I knew who made them, I could call to ask. Gary and Harold both said to pull the bearing and replace just them. If I had a spare I might try this, but don't want to have an "oops" when trying to do that and then be out of luck. The bearings in mine are getting a bit too much play in them. Thanks for the info.

Ron,
Dave Matthews will be the path of least resistance. I am almost positive that he has a pair. He got a shoebox full of little parts when he bought his ship from Mark Roberts.

The way I took my bearings out it was very easy.
I took a Dremmel with a small cutoff wheel and very surgically slowly took away the metal that stuck inward where the stakes were made to hold the bearing in.
Then I pushed on the outer race in a small arbor press and the bearing came out very easily.
When I got the new bearings, I drilled a tiny 1/32 hole in the outer race so the AeroSHELL 11 had a path from the zerks.

Thanks for the info.

Ron, were you able to contact Dave Matthews?

[Ron Spiker]

Yes, talked to him off line. None of these available. Thanks.

Hey guys. We manufactured those parts at Brantly so that would be your source.
