SERVICE AND MAINTENANCE
NOTE: Any servicing dealer attempting a
warranty repair must have prior
approval before conducting main-
tenance of a Hydro-Gear
®
product
unless the servicing dealer is a cur-
rent Authorized Hydro-Gear Service

EXTERNAL MAINTENANCE
Regular external maintenance of the T2
®
, T2-
HP
TM
and T3 HD
TM
should include the following:
1. Check the vehicle operator’s manual for
the recommended load ratings. Insure
the current application does not exceed
load rating.
2. Check oil level in accordance with Figure 3
Page 10.
3. Inspect the vehicle drive belt, idler pulley(s),
and idler spring(s). Insure that no belt
slippage can occur. Slippage can cause low
input speed to the transaxle.
4. Inspect the transaxle cooling fan for
broken or distorted blades and remove any
obstructions (grass clippings, leaves, dirt,
etc.).
5. Inspect the axle parking brake and vehicle
linkage to insure proper actuation and
adjustment of the parking brake.
6. Inspect the vehicle control linkage to the
directional control arm on transaxle. Also,
insure the control arm is securely fastened
to the trunnion arm of the transaxle.
7. Inspect the bypass mechanism on the
transaxle and vehicle linkage to insure it
actuates and releases fully.
SERVICE AND MAINTENANCE
PROCEDURES
All the service and maintenance procedures
presented on the following pages can be
performed while the T2, T2-HP or T3 HD is
mounted on the vehicle. Any repair procedures
as mentioned in the repair section of this man-
ual must be performed after the unit has been

FLUIDS
The uids used in Hydro-Gear products have
been carefully selected, and only equivalent, or
better products should be substituted.
Typically, an engine oil with a minimum rating
of 9.0 cSt (55 SUS) at 230°F (110° C) and an API
classication of SL is recommended. A 20W-50
engine oil has been selected for use by the factory
and is recommended for normal operating
temperatures.
FLUID VOLUME AND LEVEL
Fluid volume information is provided in the
Table below.
Certain situations may require additional uid
to be added or even replaced. Refer to Page
10, Figure 3 and pages 4 and 5 for the proper
ll port location.
Fill the T2, T2-HP or T3 HD to the bottom of the
oil ll port threads.
Recheck the uid level once the unit has been
operated for approximately 1 minute.
Purging may be required. Refer to the purging
