Beschreibung
Sky-Tec 149-NLR is a new 12 V in-line starter for counter-rotating Lycoming engines (left-hand rotation) with a 149-tooth ring gear, built by Hartzell Engine Tech as an FAA-PMA part. The Sky-Tec application guide lists it for the LIO-320, LIO-360, LO-360 and LTO-360 in the Piper PA-34-200, PA-39, PA-40, PA-44-180 and PA-44-180T and the Beechcraft 76, in place of the OE starter LW-14215 (equivalent MZ-4220).
The NL series is solenoid-actuated with the solenoid inside the starter and no Bendix drive, has shear-pin kickback protection and weighs 9.3 lb (4.2 kg). The 149 models have 12/14 pitch. With the jumper between the B+ and S terminals the starter runs on 12 V; the installation instructions allow 24 V with the jumper removed, while for 24 V aircraft the application guide specifies the 149-NLR/ec.
The starter is installed with the existing mounting hardware or approved replacements, torqued to 100 in-lb (11.3 N·m). Sky-Tec specifies a factory overhaul at 2,700 hours of engine operation or at engine overhaul, with no other scheduled maintenance. Installation follows the aircraft maintenance data and ends with a Certificate of Release to Service. Fit depends on the aircraft type, the engine model and the P/N of the installed starter.
