I have a 1987 ish JD490D that was converted into a Fabtek harvester sometime in the 90's. I have hydraulic oil that is leaking from underneath in the center of the machine. The oil is coming out at the main ring gear that the center is on. Reading through my book and looking on line my assumption is this may be coming from the rotary manifold somehow, my second guess was seal around the output shaft at the bottom of the swing motor could be leaking? Looking from the top of the swing motor I can not see any oil on the deck plate. Any thoughts on this? Can the rotary manifold come out from the bottom after removing the large circular cover?
