Lubricating nylon belcranks?
« on: February 15, 2007, 08:53:09 PM »
I am building an RSM Ringmaster and am just about ready to mount the bellcrank.  It is a Sig Nylon 3" crank that has a large hole in the center which has a nylon insert like a bearing. 

Should I lubricate it with anything?

Thanks for enlightening me on this (possibly) sticky issue.

Keep it dry.  No lubrication.

Steve,
I sprinkled powdered graphite on the pivot area of the nylon bellcrank before installing it in my not-an-ARF Brodak Pathfinder. Its been flying three years now and it doesn't seem to have hurt it any (some might question the planes flying ability but any deficiencies are solely the fault of the pilot n~).

P.S. Will we see you this coming weekend at the Ice-O-Lated contest?

 I always thought that nylon was self lubricating.

Hey Dennis!  I'll be there but the weather ain't lookin too good.  I hope the storms they are predicting slow down and don't hit until Monday!

Steve,
This will be the 4th contest I have attended in St. Louis in the last 3 years. On every occasion the weather in Chicago and enroute to St Louis has been TERRIBLE. However, come contest day and flying time the weather has cooperated. Sure hope we luck out again this coming weekend. Another Chicagoland Circle Cutter member, Denis Downs, felt Mike Schmitt and I were having so much fun that he's decided to attend also. I'm looking forward to flying with you and the great bunch of guys that come to the Ice-O-Lated contest.

I've always put some white lithium axle grease in the bearings of all bellcranks and control horns, , metal or nylon.

It's never hurt anything. 
Even if the nylon doesn't really need it, the grease is great insurance against paint, glue. CA, epoxy, etc, from getting into the works.
