I have an L2900 with a fluid leak where the tube from the hydraulic filter enters the transmission. Will I have to remove the filter assembly to replace the O ring?
Yes the filter assembly will have to be partially removed. The tube where it enters the transmission (suction tube assembly-040) is rigid-and won't come out far enough unless you remove the 2 bolts (020) that hold the filter assembly (010) to the case. Then you should have enough slack to pull it from the transmission housing.
