摘要

This report presents the results of a bench test program conducted to evaluate candidate seals which were proposed replacements for the 206-040-111-7 seal used on the OH58A main input driveshaft, 206-040-100. Four candidate seals were evaluated. Two driveshaft assemblies were run for 150 hours in a dense dust atmosphere while transmitting normal engine power. (Author)
