Elevator hinge lubrication

[jrevens]

I’m curious about what others have used to lubricate the elevator hinge bushings on the newer series (5,6 & 7). Thanks in advance for any replies.

I use LPS 1...

LPS1 or Triflow (with telflon).

[DesertFox4]

LPS1 on all control joints, flaperon bushings ect.

There should also be no rotation of the hinge bolt under elevator movement.

The movement is between the bushings. Edit: sorry I miss read what you said.

John I used LPS1

LPS-1 has worked well on my M4 for years.

You could probably use plain old motor oil on them to be honest, being rather
simple bushings I think any kind of lubricant would be fine as long as you apply
it on a regular basis. My only concern would be how messy it is.

I think you're right, Jeff. I can think of several specialty lubricants that would be great also, and very long lasting, but LPS-1 is easy to apply, clean, safe on plastic, etc. LPS-1 it is.
Thanks to everyone for the replies.

My build manual had a section on lubrication and it spelled out specifically the recommended lubricants for each type of joint on the aircraft. I'm wondering if you guys have seen this? I think it is in the builder's tips, or maybe the final inspection section.

Have you ever noticed how petroleums attract dirt? Especially motor oil. I understood that LPS 1 didnt do that so thats what I have used.

Thanks Jim... I had forgotten, but now remember seeing that during my initial review of the manual (a few years ago now!). According to the beginning introduction in the manual, there is supposed to be a little "oil can" symbol on the drawings next to bearings, etc. with notes to designate the proper lubricant. It turns out that there are very few of these shown on the drawings, and none on the horizontal tail surface drawings. However, in the Final Inspection Checklist section at the end of the manual, it has a list of recommended lubricants. Sure enough, LPS-1 is listed for the elevator hinges.

Kitfox SS assembly manual( rev.A , 05/11), section "O", final inspection checkout, page 100: elevator hinge, use LPS 1.

The rational for using LPS-1. I does not leave a residue to attract dust, which will add friction and wear the bearings/bushings.

I believe that section in the manual recommends Tri-Flow for the rod end joints; it also is a lubricant that does not attract dust. LPS-1 and Tri-Flow pretty much takes care of most ongoing maintenance lubrication.
