Experimental results are presented for modified, grease-lubricated H-3 intermediate and tail gearboxes operated on a regenerative test facility and an actual H-3 tiedown aircraft. The H-3 intermediate and tail gearboxes were suitably modified for operation with grease lubrication and utilized a lubricant conforming to specification MIL-G-83363 (USAF). A 10-hour bench test was conducted followed by a 50-hour tiedown test on an NSH-3A aircraft.
