Gear doors rod ends

[bmcconnaha]

I have a sticky rod end on my gears doors.  Mooney wants $700 for a new rod.  I’m trying to get this one freed up.  Anyone have any tricks? I tried both triflow and LPS2, no real change.  
 

thanks!

Remove the rod end.  Put a bolt with split washers on both side and tighten, this should lock the bolt to the ball. .  Place the rod end in a vice and spray with penetrant.  Place a wrench on the bolt and work back and forth.  You don't want to see the brass collars rotating.  You can also use a product called frezZ-it that with give a thermal shock to the part to brake the rust.  Enjoy

My favorite penetrating oil is Kroil.

Also, the ends are standard parts.    You can by the spherical rod ends (aka heim joint, whatever) at other suppliers.

Like @LANCECASPER I use Kroil (both the spray can with straw and the "drip can") but you can probably replace a rod end cheaper than you can buy the Kroil.

Kroil is good. If that doesn't work, try mix of 1/2 Dexron ATF fluid and 1/2 Stoddard solvent. 

Some Mooney linkages have rod ends welded on.

Well now that complicates things, doesn't it?

You could make one from a length of 4130 tubing and two new rod end bearing, tap the tube for 1/4-28 NF threads and screw the rod ends in and secure with a jam nut.

Last resort is the hot wrench.

+1, those are real simple pieces.   The primary important dimensions are just the inside diameters of the sphere holes for the bolts and the min/max adjustable length.

I heard the ATF trick from someone today, I’ll give that a shot as well.  This rod has a welded end, unfortunately

Not if you want to sell $700 parts it doesn't

Frankly, 700 for that part is insanity. I was surprised to hear that today.
