jamesm Posted May 15, 2022 Report Share Posted May 15, 2022 I can't remember who but someone once told me if you don't have washer between the bolt head or nut end of the rod end. it is possible for the ball of the rod end to pop out of rod end housing. that cause me to double check anytime I see a rod end to verify there is washer at very least nut and bolt end of the assembly.

I believe you are referring to the practice of installing a large planform washer on a rod end where there is a possibility that if the socket came off the ball it could slip over the the nut or bolt head and become disconnected. I know some experimental builders do this, but I don't know how prevalent it is on production aircraft. And I have no idea how often rod ends fail in this way.

Skip It’s depends on manufacturer and models. Some add the penny washer and some don’t. I’ll often add one where it doesn’t interfere with the installation.

Skip My engine control cables all have them but I think one of them is installed wrong (probably by me). Next time the cowl is off I'll probably fix it. I just finished my annual and I looked at these aileron links while the belly was off. Mine move quite a bit and there's a bare spot on the landing gear actuator tube where it's been rubbing, but it doesn't really seem to be problematic. I suspect it's been like that for a loooong time. I'll see what the kit costs and whether the local MSC has it or can get it and maybe put it in next year. 1 Quote Link to comment Share on other sites More sharing options...

Since the kit give the dimesions of the spacers and the rest is common hardware, you could also just make the spacers. Quote Link to comment Share on other sites More sharing options...

Yeah, was looking at that. Lasar lists the kit at $271 but says they don't have them. The spacer material isn't indicated, though. Nylon?

Guest Posted May 16, 2022 Report Share Posted May 16, 2022 The three spacers are steel. If the kit is our of stock, see if the spacers are available individually. The bolt and nut are standard AN parts. Clarence Quote Link to comment Share on other sites More sharing options...

The I.D. seems to be much bigger than the bolt, too, so that seems to be an additional unknown. Quote Link to comment Share on other sites More sharing options...

The spacers are essentially a steel washer that fits around and over the steel ball of the rod end bearing. The centre spacer is twice as thick as the two outer spacers.
