SECTION 5. REPAIR
HOW TO USE THIS SECTION
Each subassembly illustrated in this section is
illustrated by an exploded view showing the
parts involved. The item reference numbers
in each illustration are for assembly
instructions only. See pages 31 and 33 for
part names and descriptions. A complete ex-
ploded view and item list of the transaxle is pro-
vided at the end of this section.
Many of the parts and subassemblies of this
transaxle can be removed and serviced inde-
pendently of other components. Where some
components and assemblies must be removed
before a given assembly can be serviced, that
information is given at the beginning of the
disassembly instructions.
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 using 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,
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 listed in BLN-50937 (microfiche) or
BLN-51427 (CD).
IMPORTANT: When internal repair is per-
formed on the 310-0510 IHT, the filter assem-
bly must be replaced.
TRANSAXLE REMOVAL
It is necessary to remove the 310-0510 from
the vehicle before performing the repair
procedures presented in this section.
LIMITED DISASSEMBLY
The following procedures are presented in the

completely disassemble the unit. Do not
disassemble the unit any farther than is
necessary to accomplish the required repairs.
Each disassembly procedure is followed by a
corresponding assembly procedure.
Reassembly is accomplished by performing the
“Assembly” portions of the procedures. If the
unit has been completely disassembled, a sum-
mary of the assembly procedures, in the order
in which they should occur, is given on page
