Plug/pilot A518,42RE,A500,46RE

Plug/pilot A518,42RE,A500,46RE End Plugs (5) Pilots (5) The Sonnax pilot has a smaller orifice, resulting in more lube flow to the bushings and planetaries. The use of the Sonnax pilot allows the salvage or conversion of early, small-diameter pilot A727 shafts to later, large-diameter applications. The Sonnax end plug allows the shaft to be cleaned, preventing post-rebuild contamination. Symptoms: Poor lube oil control Recontamination of new parts Unable to clean shaft Cause: Shaft oil galley is not properly cleaned unless plugs are removed. Plugs that are left out or replaced with larger orifices decrease critical lube to planetaries. Correction: This pilot has a reduced orifice for improved lube flow, and end plug allows the shaft galley to be cleaned and a replacement plug installed.
