I'm  in the process of installing the aileron bellcranks.  Should they 

be lubed in any way?



The parts include an AN4 bolt, going thru a brass bushing that goes thru 

the 4130 steel bellcrank body.



It seems that a light application of something like lubriplate would be 

a good thing, but I hear  that some bearings can be damaged by 

lubrication (by holding abrasive debris in place)..



I also have some unfinished steel surfaces at the ends of the bellcrank 

shaft where I filed away the powdercoat.  Seems to be that those 

surfaces should be lightly lubed.  I'm thinking that primer or paint 

will be worn/wiped away very quickly.

I put lubriplate on mine.  My parts did need some tweaking filing to get 

a good fit and not bind.  The bell crank  area should be closed and not 

in an area where one would worry a lot about dirt.  Keep the lubriplate 

off the threads so as not to mess up the proper torque.

That sounds about right to me.  Thanks for the tip about the threads.



I just ran across an inventory problem - In bag 1255 I had only 2 of 4 

pushrod ends for the torque tube assembly.  I had marked it as 4 when I 

inventoried the bag but it just took me 20mins to re-inventory the bag 

before calling Vans.  There's no way I would have taken the time 

necessary during the initial inventory.  Too many hard to identify rod 

ends and bushings.  Oh well.

I generally use LPS spray lubricant  on all moving parts of the control

system.  Should be aplied at each annual "condition inspection" as well.

I've got to order some from AS&S this week, Bill.  Do you want me to

order a can for you as well?

Thanks Jack but I'll be placing an order for other stuff within the week 

- one way or the other.



BTW, I flew into Cox Monday evening.  An uneventful downwind/uphill 

landing - great fun.  Didn't have my cell or would have called.  Nice 

place!  I'd love to watch that dusty M20 fly in and out.... maybe not.



Stop by for lunch soon or I'll be calling you  for the dreaded top wing 

skin riveting.
