11     16     Change of Travel speed    Swivel (22) accomplishes two functions. Swivel (22) supplies pump oil from the upper structure to the travel motors of the lower structure. The upper structure swings. The lower structure does not swing. Swivel (22) returns oil from the travel motors to the hydraulic tank.Housing (9) is restrained to the upper structure through support (23). Support (23) is used as a torque arm in order to prevent housing (9) from rotating. Rotor (14) is bolted to the lower structure through plate (15). The ports of housing (9) are open to the ports of rotor (14). The passages in housing (9) and the passages in rotor (14) connect the ports.Seal (6) for high pressure and seal (13) for low pressure are provided between the sliding surfaces of housing (9) and rotor (14). Seals (6) and (13) prevent oil leakage between the passages.Swivel (Leveling)

8     A     Change of Travel speed    The swivel accomplishes two functions. The swivel supplies pump oil from the upper structure to the travel motors of the lower structure and to the cylinders for the leveling system. The upper structure swings. The lower structure does not swing. The swivel returns oil from the travel motors and the cylinders to the hydraulic tank.Housing (4) is attached to housing (5) with a seal. Housing (5) is restrained to the upper structure through a support that is attached to the lower structure. The
