I have a 254 TYM. , Its main job is snow blowing. Went to do my 50 hour service and broke the suction filter right off. This thing has a 19 mm hex head. Its made of white metal with 4 holes before the inserted threads. It also holds the knuckle for the return block on the hyd/stat case. What a bad design. Any pressure on the hex nut will snap it right off. Is there a torque rating on this thing? Help dont want to bust the new one I ordered.
