FLUIDS
The fluids 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
classification of SL is recommended. A 20W50
engine oil has been selected for use by the fac-
tory and is recommended for normal operating
procedures.
FLUID VOLUME AND LEVEL
Fluid volume information is provided in Table 4.
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 310-2200 so the oil level is .75”-1.50”
(19-38 mm) below the oil fill port.
Recheck the fluid level once the unit has been
operated for approximately 1 minute.
Purging will be required. Refer to the purging
procedures on Page 10.
SECTION 4. SERVICE AND MAINTENANCE
NOTE: Any servicing dealer attempting
a warranty repair must have prior ap-
proval before conducting maintenance of
a Hydro-Gear
®
product unless the servic-
ing dealer is a current Authorized Hydro-
Gear Service Center.
EXTERNAL MAINTENANCE
Regular external maintenance of the 310-2200
EZT
®
should include the following:
1. Check the vehicle operator’s manual for
the recommended load ratings. Insure
that the current application does not ex-
ceed load rating.
2. Check oil level in accordance with Figure 4
Page 9.
3. Inspect the vehicle drive belt, idler pulley(s),
and idler spring(s). Insure that no belt slip-
page can occur. Slippage can cause low in-
put speed to the transmission.
4. Inspect the vehicle control linkage to the di-
rectional control arm on the transaxle. Also
insure that the control arm is securely fas-
tened to the trunnion arm of the transaxle.
5. Inspect the bypass mechanism on the
transaxle and the vehicle linkage to insure
that both actuate and release fully.
