Cub Cadet T2-HP - Manual (Page 6)

2 T2 ®
The T2 has a self contained fluid supply and
an internal filter. The fluid is forced through
the filter by a positive “head” on the fluid in the
housing/expansion tank with an assist by the
negative pressure created in the pump pistons
as they operate .
The check valves in the center section are used
to control the makeup flow of the fluid to the low
pressure side of the loop .
A block lifting bypass is utilized in the T2 to
permit moving the vehicle for a short distance
at a maximum of 2 m .p .h . (3 .2 Km/h) without
starting the engine . The T2 utilizes an in-line
floating disc brake controlled by a “cam” style
actuating arm .
InTrOduCTIOn
The purpose of this manual is to provide infor-
mation useful in servicing the Hydro-Gear ® T2 ®
Integrated Hydrostatic Transaxle . This manual
includes the T2’s general description, hydraulic
schematic, technical specifications, servicing
and troubleshooting procedures .
The transaxle normally will not require servic-
ing during the life of the vehicle in which it is
installed . Should other servicing be required,
the exterior of the transaxle will need to be
thoroughly cleaned before beginning most
procedures . Do not wash the transaxle while it
is hot . Do not use a pressure washer to clean
the unit .
General desCrIpTIOn
The T2 is a self contained unit designed for the
transfer and control of power . It provides an in-
finitely variable speed range between zero and
maximum in both forward and reverse modes
of operation .
This transaxle uses a variable displacement
pump with a maximum displacement of 8cc
per revolution, and motor with a fixed dis-
placement of 10 .2cc per revolution . The vari-
able displacement pump features a trunnion
mounted swashplate with a direct-proportional
displacement control . Reversing the direction
of the swashplate reverses the flow of oil from
the pump and thus reverses the direction of the
motor output rotation . The pump and motor are
of the axial piston design and utilize spherical
nosed pistons which are held against a thrust
race by internal compression springs .
