Heim joint/spindal question

[Keyser Soze]

I replaced the stock heims on my full flight a-arms with america star chromology heims. With the old spindal inserts I did not have to ream out the spindals. When I changed them out the bottoms went on fine with plenty of thread sticking out. The spindal insert does not seem like it goes down as far in the uppers. I have enough thread coming out to get a nut on and to have a little sticking out...but not enough to run a carter pin through.

 

So basically all four spindal inserts are the same

The four old spindal inserts went in fine

The spindal inserts on the lowers went in fine

 

Spindal inserts on uppers are not going as far on the uppers

 

Anyone ever had such a strange problem? I used lock tight and torqued the bolt thinking it would sink farther in the spindal..Enough threads were out to get the nut on with a little thread coming out of the nut but not enough for a carter pin...is this safe to run?

Are you using castle nuts or regular nuts? Castle nuts have the notches in them for the cotter pin? if they are castle nuts, no it is not safe, and if they are reglar nut, get some castle nuts and you will be fine. I would want to have maximum thread engagement, I have old style Lonestar D arms and A arms on my 89 that use the Warrior screw in ball joints and one time when I was pounding whoop de doos, I had a nut pull off through all the threads AND the cotter pin.

I could pick up some castle nuts but when I ordered the spindal inserts the came with regular nuts w/ nylon inserts

[T_Shee]

so they sent you nylon lock nuts in place of castle nuts? if so you should be fine. as long as you have some stud sticking up through the nylon nut they wont come off.

Yeap there is some thread sticking out just not enough for a cotter pin. I may be able to get one on with a castle nut. Just wondering if maybe the top part of my spindals got tweaked or something?

Got it figured out. Customer service is really good at american star. Explained the guy my problem and described how much thread sticking I had sticking out. He said it sounded like they were for Articat spindals. It was acutally my mistake. Ordered two and thought I would go ahead and replace all four, when I reorded I forgot to drop down and select Yamaha, articat is selected by default.
