Eaton Model 781
This transaxle is used as a pair (RH & LH) to
make up a complete drive system. It has a
variable radial-ball piston pump and fixed
displacement radial-ball motor. Maximum pump
output is 0.465 cu.in.(7.62cc) per revolution.
The motor output is 0.767 cu.
in.
(12.57 cc) per
revolution. It does not use a charge pump. A
remote expansion tank is used for a reservoir
with a fine screen at the bottom of the inlet line
providing the filtration of incoming oil. Two sets
of planetary reduction gears provide power to
the axle.
Hydro-Gear 316-0500
This is a typical hydrostatic transaxle used in a
lawn tractor
It
is completely self-contained and
has its own differential. This transaxle utilizes a
variable axial piston pump with a maximum
displacement of 0.61 cu. in. (10 cc) per
revolution. The motor is also an axial piston
design with a fixed displacement of 1.28 cu. in.
(21 cc) per revolution.
Hydro-Gear 316-0750
This hydrostatic transaxle is similar to the
316-0500. It uses a heavier differential to handle
higher loads. This transaxle utilizes a variable
axial piston pump with a maximum displacement
of 0.61 cu. in. (10 cc) per revolution. The motor
is also an axial piston design with a fixed
displacement of 1.28 cu. in. (21
cc)
per
revolution.
