I'm ready to install the aileron bellcranks in the wings (RV14). Not sure about other models, but the bellcrank design for -14 has a brass bushing that is inserted into the steel housing of the bellcrank. The assembly is placed in position and secured using a AN4-32A. When the bolt is properly torqued, the bolt and brass bushing are to remain stationary with the rotation occurring between the bushing and the steel bellcrank. There is no mention in the plans of lubricating this rotation point, but I was thinking it may be a good idea. My question is what would be the better lubrication. LPS-2 and Lubriplate 630-AA are two products that I'm considering. It seems both may have pros and cons.
The pros for the Lubriplate would seem to be longer lasting. However, the con would be when it is time to replace, the bellcrank assembly would need to be disassembled. Also, will this lubriplate break down during the heat of the summer and drip out the bottom? That's what happens to grease in my grease guns out in the garage during summer. The pro for the LPS-2 would seem that when time to re-lube, it would just require opening the access panel on the bottom wing skin and applying fresh lube using a flexible tube. The con for LPS-2 would seem that it would need to be re-applied at shorter intervals.
I realize I'm overthinking this, but was just curious what others have used, and actual lubrication requirements for this part once in service.
