Does anybody know what oiling mod is done to the 904 case to provide more oil to the sprag?
More 727 questions oil feed holes
scroll down to the 11th and 12th post to see pictures of a 727. Dimensions are different for 904 but theory is the same. Drill a 0.060” hole in the rear cooler line passage that intersects the center of the over running clutch inner race contact patch. The four rear support bolts and support must be removed to drill. Carefully measure the intersection point. Hope that helps. John
