push/pull tubes

[airlina]

Anyone know what lubricant Kitfox recommends to use on the push pull tube? Or is just the Teflon bushing good without lubricant?

I see that Joe is asking about a Series 5 which has a phenolic (plastic) bearing/bushing that the elevator torque tube goes thru about mid fuselage back in the airframe. Joe if that is what you're asking about I use a dab of white lithium grease on the tube where it slides thru this bearing. Not sure , but I believe on the newer models this bearing has been eliminated. Bruce N199CL

Yes the KF5 has a plastic bushing half way back. That is what I am asking about. But I would be concerned using anything that would collect dust or dirt. If I get a chance today I will contact Kitfox and ask.

Agreed, LPS-1 or Triflow are at the top of my list. Grease in the wrong place attracts dirt & water and accelerates wear.

I lube the plastic bushing on my KF-5 annually. When I use up my can of LPS-1 I will be switching to Triflow.

I would use LPS-1 on plastic bearings, as per Kitfox recommendations. Tri-Flow on metal to metal.
