Hradec Posted December 11, 2021 Report Share Posted December 11, 2021 In the process of going through my very neglected 64 m20e. Trying to figure out what lube to put on the flight control walking beam and flap shaft needle bearings. The lube on them is old and hard, rollers weren't moving. Cleaned with mineral spirits, moving now, but they need grease. Any recommendation on something that wont dry out and get hard over time? I was thinking aeroshell 22? Just wanted to add these are the components mounted on the aft spar. Thanks, Glenn Quote Link to comment Share on other sites More sharing options...
markgrue Posted December 11, 2021 Report Share Posted December 11, 2021 I generally use aeroshell 33 for everything except wheel bearing and control tube. Mobile 100 for wheel bearing and aeroshell 22 on control tubes Mark 1 1 Quote Link to comment Share on other sites More sharing options...
Andy95W Posted December 11, 2021 Report Share Posted December 11, 2021 You really need to do what the Service Manual specifies, for this and everything else you do. The service manual specifies low temperature oil, MIL-L-7870. Typically, most use LPS-2 or Tri-Flow. 2 Quote Link to comment Share on other sites More sharing options...
