(36) Tee fitting that divides flow to front and rear differential clutches The OTG pump (21) supplies oil to OTG filter (24). Oil from filter (24) goes to control valve (25). When energized, control (25) sends oil to the front and rear cross axle differentials. The 725C does not have a center axle differential clutch.
