CHECK SPARK PLUGS
Service Interval: Every 100 Hours
Remove spark plugs, check condition and reset
gaps, or replace with new plugs. See Engine
Owner’s Manual.
CHANGE HYDRAULIC SYSTEM FILTER
AND FLUID
Service Interval: Every 400 Hours
ZT-5400
This transaxle is designed with a serviceable filter.
To ensure constant fluid quality levels and longer
life, an initial oil and filter change at 100 hours is
recommended. Subsequent changes are
recommended at 400-hour intervals minimum, or
yearly, whichever comes first.
The following procedure can be performed with the
transaxle installed in the vehicle, and the vehicle on
level ground. Apply the bypass valve and lock the
vehicle parking brake.
1.
Place an oil drain pan (12” or more in diameter
and 8 qt. capacity is optimal) beneath the oil
filter. Remove the oil filter cover from the
transaxle to drain the oil. Remove the O-ring
from the cover and discard the O-ring.
2. After the oil has drained from the transaxle,
remove the oil filter from the transaxle housing.
3. Install a new filter (Hydro-Gear part number
71943). Install a new O-ring onto the filter
cover and install the filter cover. See figure
below. Torque to
480-580 in-lbs [54.23-65.53
Nm]
4. Remove the top oil fill vent port plug and fill the
transaxle with new 20w50 motor oil through the
expansion tank port/fill port until oil reaches the
oil fill vent port.
5. Install the top oil fill vent port plug and continue
filling the system with oil until the fill line is
reached in the expansion tank.
6. Drain old oil filter of all free-flowing oil prior to
disposal. Place used oil in appropriate
containers and deliver to an approved recycling
collection facility.
7. Proceed to the purge procedure.
CAUTION
Raising the mower for service or
maintenance relying solely on mechanical
or hydraulic jacks could be dangerous. The
mechanical or hydraulic jacks may not be
enough support or may malfunction
allowing the unit to fall, which could cause
injury.
Do not rely solely on mechanical or
hydraulic jacks for support. Use adequate
jack stands or equivalent support.
HYDRAULIC SYSTEM AIR PURGE
Service Interval: As Required
Due to the effects air has on efficiency in
hydrostatic drive applications, it is critical that air is
removed or purged from the system.
These purge procedures must be performed
anytime a hydrostatic system has been opened for
maintenance or repair, or if any additional oil has
been added to the system.
Air creates inefficiency because it has compression
and expansion rates that are higher than that of oil.
