NATOPS1 Posted September 6, 2014 Share Posted September 6, 2014 Gear box is bad... The drive spline is worn causing the failure. Quote Link to comment Share on other sites More sharing options...

NATOPS1 Posted September 6, 2014 Share Posted September 6, 2014 There is a drive spline "Insert" to eliminate the Gearbox wear issue. Quote Link to comment Share on other sites More sharing options...
HercMX Posted September 8, 2014 Share Posted September 8, 2014 Wasn't that a 100hr inspection item a few years back.. I seem to have removed several in the past to clean and lube both sides... Jack... Quote Link to comment Share on other sites More sharing options...
NATOPS1 Posted September 8, 2014 Share Posted September 8, 2014 Not sure of the timeframe for inspection but had a go nogo tool to check for wear and then went to the insert to prevent the wear all together... Quote Link to comment Share on other sites More sharing options...
