Note that larger (1") axle shafts make it necessary to specify a seal kit and axle bushings different
from the 310-0510 unit. The center section, pump cylinder block assembly, and associated kits
also differ from those on the 310-0510. Refer to the appropriate model schematic for specific
component part numbers.
