I am getting confused by this thread, the 500 and 550 are different gear boxes. lucky that I am building a 550 today. Hope the pics help. (Attachment Link)
Hey Trig, what's the red stuff on the second gear from the left on the output shaft in the first pic? Also traces of it around a couple of the main bearings?
Looks like its been to the dentist The damage is not caused by wear, it has been knocked down the gears at high speed to do that sort of carnage A little worried that the roller bearing housing pins look flush in the journals.
