SECTION 4. SERVICE AND MAINTENANCE
NOTE: Any servicing dealer attempting
a warranty repair must have prior
approval before conducting maintenance
of a Hydro-Gear
servicing dealer is a current Authorized
Hydro-Gear Service Center.

EXTERNAL MAINTENANCE

Regular external maintenance of the 310-0510
IHT 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 4
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 transmission.
4. Inspect the transmission 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.

better products should be substituted.
Typically, an engine oil with a minimum rating
of 55 SUS at 212°F (100° C) and an API classi-
fication of SL is recommended. A 20W-50 en-
gine oil has been selected for use by the fac-
tory and is recommended for normal operating
temperatures.

Certain situations may require additional fluid to
be added or even replaced. Refer to Page 4
and Figure 4 for the proper fill port location.
Fill the 310-0510 to the top of the oil fill port.
Recheck the fluid level once the unit has been
operated for approximately 1 minute.
Purging may be required. Refer to the purging
procedures on page 11.
