How To usE THis Manual
Each subassembly illustrated in this section is
illustrated with an exploded view showing the

gEnEral insTrucTions
Cleanliness is a primary means of assuring
satisfactory life on repaired units. Thoroughly
clean all exposed surfaces prior to any type
of maintenance. Cleaning of all parts by us-
ing a solvent wash and air drying is usually
adequate. As with any precision equipment,
all parts must be kept free of foreign material
and chemicals.
Protect all exposed sealing surfaces and open
cavities from damage and foreign material. The
external surfaces should be cleaned before
beginning any repairs.
Upon removal, it is recommended that all seals,
O-rings, and gaskets be replaced. During
installation lightly lubricate all seals, O-rings
and gaskets with a clean petroleum jelly prior
to assembly. Also protect the inner diameter of
seals by covering the shaft with a cellophane
(plastic wrap, etc.) material.
Parts requiring replacement must be replaced
from the appropriate kits identified in the Items
Listing, found at the end of this manual. Use
only original Hydro-Gear ® replacement parts
found in BLN-51427 (CD).
iMporTanT: When internal repair is per-
formed on the EZT ® , the filter assembly must
be replaced.
TransaXlE rEMoval
It is necessary to remove the EZT from the ve-
hicle before performing the repair procedures
presented in this section.
noTE: if removing the wheel from the
transaxle, do so by removing the four (4)
lug nuts. do not remove the axle/hub nut.
liMiTEd disassEMBlY
The following procedures are presented in
the order in which they must be performed to
completely disassemble the unit. Do not disas-
semble the unit any farther than is necessary
to accomplish the required repairs. Each disas-
sembly procedure is followed by a correspond-
ing assembly procedure.
Reassembly is accomplished by performing
the “Assembly” portions of the procedures. If
the unit has been completely disassembled, a
summary of the assembly procedures, in the
order in which they should occur, is given on
page 29.
