Good lubricant for assembly

Yes, some may say the "wings will fall off" if you use the wrong lube. In this case, not likely.

I can't agree with the "anything" specification. The main pins do not move, but the lift and drag pins clearly do work in flight, with considerable pressure on them. Any glider a few years old will show signs of wear, galling, or Brinelling on those pins. From this is seems to me that something with some extreme pressure ingredients is desirable.

Oh, I don't disagree, trust me with my mechanical background.
Dry is among the worst case, crappy lube is better than nothing.

While we strive to be in the "perfect world", Vaseline is way better than nothing.

Not everyone wants to spend "x" dollars on lube, just like some peeps try to do a season with one set of wing tapes to the fuselage.

I am not here to judge, just saying Vaseline is way better than nothing.

I have been chastised when pulling wing tape and balling it up.
I just "wasted" a seasons worth of tape....shame on me......
Thus I use Scotch type 33 white electrical tape. Not a killer on price and easy to get.

I just ordered a small pot of ball bearing grease which Dan Daly suggested to try out, as I used up all my vaseline. I just need them for the main pins to assemble the wings on my DG 101.

I might take a look at Amazon next, when I've tried this one.

My observations as well regarding wear. After replacing a set of lift pins I switched away from "Superlube" to a lithium based grease designed for high bearing pressures.

Hey Craig,

For what it's worth... Superlube with PTFE (the one in the tube many of us use) is NLGI rated GC-LB. Per the NLGI folks: "Grease packaging may display the code GC-LB, meaning that it meets the most demanding test standards for both chassis and wheel bearings. Grease products displaying this highest rating meet OEM requirements." Among other comments, it says "Wide temperature grease for use in components such as bearings, chassis and universal joints in passenger cars, trucks, and other vehicles under mild and severe duty.This includes vehicles operated under frequent stop-and-go service (buses, taxis, urban police cars, etc.), or under severe braking service (trailer towing, heavy loading, mountain driving, etc.) (see ASTM D4950)."

Just curious what the specs of the other grease you are using meets. Not doubting you, just looking for data.

HI Eric,

I just switched to Lucas "Red 'n' Tacky". It has the same NLGI GC-LB rating.. I hadn't seen anything in the Superlube literature that talked about extreme pressure suitability. It's entirely possible I missed that.

Eric,

30 seconds of googling produced a spec sheet for an extreme pressure version of Superlube. http://www.super-lube.com/tech-data-...re-ezp-92.html

It's even "Kosher Certified" - WOW! That has finally convinced me.

Of note: The Lucas "Red 'n' Tacky" has a Timken OK load rating of 60 lb whereas the Superlube has a lower rating of 40 lb.

My observations are that this type of high pressure sliding capacity along with corrosion resistance is what matters for pin longevity.

Hi Jon, might I ask what you use for pin lube?
