An extensive range of standard MIL-SPEC and Cessna pulleys and pulley kits is offered by McFARLANE® AVIATION. The kits contain all pulleys and cotter pins required to replace all flight control system pulleys in one airplane containing the respective part numbers and quantities required. Different McFarlane pulley series include:
MCS378 Series phenolic flight control pulleys with ball bearings, FAA-PMA approved replacements for the Cessna S378, A-/BB-, and NAS383- series pulleys on Cessna Aircraft. The MCS378- series pulleys supersede these for most Cessna aircraft applications and feature high quality sealed precision ball bearings, superior to low grade, open seal bearings used in the Cessna S378-()L light duty series pulleys that they replace.
MS20219 Series aircraft secondary control pulleys, superseding the respective AN219 series pulleys are offered either with high pressure laminated phenolic sheave (MS20219 Series) or aluminum alloy sheave anodized per MIL-A-8625 (MS20219A Series), both with fixed ball bearing with contact seal. The aluminum body is recommended for -1 and -3 pulleys. The -1 pulley should not be installed in flight control systems.
MS20220 Series phenolic flight control pulleys with ball bearings. These supersede the AN220- Series pulleys of like dash number.
MS24566 Series phenolic flight control pulleys with ball bearings. MS24566 pulleys can be used to replace the corresponding AN210 pulleys designated by the letters "A" or "B" in their dash numbers as they differ in the maximum load limit.
