Introduction/General Description
Introduction
The purpose of this manual is to provide information useful
in servicing the 210-3010L Hydrostatic Transaxle. This
manual includes unit and component description, troubleshooting, maintenance, and repair procedures.
A transaxle normally will not require servicing, other than
recommended fluid and filter changes, if any, and an
occasional brake adjustment during the life of the vehicle in
which it is installed. Should other servicing be required, the
unit must be removed from its installed location and thoroughly cleaned before beginning most procedures.
General Description
The 210-3010L Hydrostatic Transaxle is a self contained unit
designed for the transfer and control of power. It provides an
infinitely variable speed range between zero and maximum
in both forward and reverse modes of operation.
The BDU-10L transmission is a “U” style transmission with
a variable displacement pump and a fixed displacement
motor. The variable displacement pump features a cradle
swashplate with a direct-proportional displacement control.
Reversing the direction of tilt of the swashplate reverses the
flow of oil from the pump and thus reverses the direction of
the motor output rotation. The fixed displacement motor
uses a fixed swashplate. The pump and motor are of the axial
piston design and utilize spherical nosed pistons which are
held against a thrust race by internal compression springs.
The 210-3010L Hydrostatic Transaxle is a package consisting of two primary components, the 210-3000 axle assembly
and the BDU-10L Hydrostatic Transmission.

General Description
The fluid supply for the BDU-10L transmission is shared by
the axle. The oil passes from the axle housing through a filter
prior to entering the transmission and feeding the fixed
displacement gerotor charge pump. Excess fluid in the
charge circuit is discharged over the charge relief valve back
to charge pump inlet. Flow across a small fixed orifice
connecting the charge circuit to the transmission housing
supplements the cooling flow.
Charge check valves in the center section are used to control
the makeup flow of fluid to the low pressure side of the loop.
A spool type bypass valve is utilized in the BDU-10L
transmission to permit moving the vehicle for short distances at low speeds (2mph) (3.2km/hr) without starting the
engine.
The 210-3000 axle assembly is a spur gear reduction
transfer case with an integrated “heavy duty” spur gear
differential.
The 210-3000 axle assembly utilizes an inline floating disc
brake controlled by a “cam” style actuating arm.
210-3010L
Fluids/Greases
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 55 SUS at
210°F (98.9°C) and an API classification of SJ/CD is
recommended. A 10W-40 engine oil has been selected for
use by the factory and is recommended for normal operating
temperatures. Another alternative that will provide excellent
all climate performance and extended time between oil
changes is a 15W-50 synthetic engine oil.

Safety Precautions
Certain procedures may require the vehicle to be disabled
(wheels raised off the ground, engine disconnected, etc.) in
order to prevent possible injury to the technician and bystanders.
Some cleaning solvents are flammable. To avoid possible
fire do not use cleaning solvents in an area where a source
of ignition may be present.
The loss of hydrostatic driveline power may result in the loss
of hydrostatic braking capacity. Proper brake maintenance
becomes very important should this condition develop.
Maintenance
Check the transaxle cooling fan for broken or distorted
blades, and check to see that the fan is securely fastened.
Replace the fan if damaged.
Keep the transaxle clean. Grass clippings and dirt will effect
the cooling efficiency of the fins on the transaxle housings.
Avoid high pressure washing, compressed air is the preferred method of removing loose debris.
Maintenance
210-3010L Hydrostatic Transaxle
Inspect the brake for proper operation. If the brake fails to
stop the vehicle or hold on a 30% slope, adjustments are
necessary. You should make sure it fully disengages when
the pedal is released.
Check to make sure the bypasss valve and linkage is
operational. The bypass valve should be fully released
before operating the vehicle. It should extend approximately
0.22" (5.58 mm) from the hex nut.
Inspect the transaxle for leaks at the lip seals, damage to
fittings, hoses, the filter, or to the housings. Check the oil
level and add oil as necessary to bring it up to the proper
level.

Maintenance
Oil & Filter Change
Oil and filter changes should occur approximately every 200
hours of operation or once each year.
More frequent oil and filter changes are recommended if
operating conditions are severe or adverse, such as pulling
a plow or a tiller for extended periods, or operating in very
dusty conditions.
Refer to the following illustrations for the proper fill port and
oil level port locations on your transaxle. These locations will
be different on various models and it may be necessary to
refer to the vehicle owners manual.
Configuration A. Remove the filter and allow the oil to drain
through the filter mounting base. After the oil stops flowing
you may install the new filter and tighten 3/4 of one turn after
the filter seal touches the filter mounting base.
Configuration B. Drain the oil at bottom most fitting. Refer
to vehicle owners manual for correct procedures.
210-3010L
Configuration A
Refill the transaxle case to the correct level with the
recommended oil type listed in the Fluids section (refer to
illustrations for correct oil fill and oil level ports). The oil level
should be rechecked after running the vehicle for a short time
(1 minute will be adequate).

Parking Brake
The brake was factory set for a specific running clearance
between the disc and pucks of 0.020" (.508 mm).
Place a feeler gage between the disc and one puck, if the
clearance is not set properly remove the cotter pin retaining
the castle nut and set the correct clearance by adjusting the
castle nut accordingly. Reinstall the cotter pin.
Maintenance
Brake Components
Brake Adjustments
If the correct adjustment was not achieved you will need to
replace the brake pucks. Start by removing the cotter pin,
castle nut, washer and brake actuating arm. Remove the
brake yoke assembly and pull the disc from the shaft.
Clean the brake area and all components thoroughly with a
degreasing solvent before reassembly.
During reassembly apply a dry graphite lubricant to the brake
shaft, brake actuating pins and cam area of the brake
actuating arm. Take precaution to not allow any lubricant
onto the brake disc or pucks during reassembly.
Reassemble the brake with new pucks and torque the bolt
and nut to 7-10 ft.lbs. (9.5-13.5 Nm).
Set the correct clearance (0.020") (.508 mm) and lock the
castle nut with the cotter pin.

Minor Repairs
Minor Repairs
General Information
Minor Repairs may be performed, following the procedures
in this section, without voiding the unit warranty.
Cleanliness is a primary means of assuring satisfactory life
on either new or repaired units. Cleaning parts by using
solvent wash and air drying is usually adequate. As with any
precision equipment, all parts must be kept free of foreign
materials and chemicals.
Protect all exposed sealing surfaces and open cavities from
damage and foreign material. The outer surfaces must be
cleaned before beginning any repairs.
It is recommended that all O-rings and seals be replaced.
Lightly lubricate all O-rings and seals with a clean petroleum
jelly prior to assembly.
Each of the following repairs except brake adjustments will
require the oil levels to be checked prior to operating the
vehicle as some oil will be lost.
210-3010L
Shaft Seals
Lip type seals are used on the pump input shaft, pump
through shaft (not all models use the through shaft), motor
output shaft and displacement control shaft of the BDU-10L,
as well as on the brake shaft and axle shafts (in the main
housing halves only) of the 210-3000. These seals can be
replaced without major disassembly of the unit. However,
replacement of the seals generally requires removal of the
transaxle from the machine.
To replace the pump input shaft seal, first remove the
retaining ring from the housing.
Carefully pull the seal out of the housing bore. A “hook” type
tool may be used to grasp the seal and pull it out, or a slide
hammer type puller may be used to remove the seal. Care
must be taken so as not to damage the housing bore, shaft
sealing surface, or bearing. Once removed, the seal is not
reusable.
Inspect the sealing area on the shaft for rust, wear, or
contamination. Polish the sealing area on the shaft if
necessary.
Plug/Fitting Torques
If any plugs were removed during servicing, they should be
torqued as indicated in the accompanying table:

or cellophane to prevent damage to the seal lip during
installation.
Slide the seal over the shaft and press it into the housing
bore. Be careful not to damage the seal.
Install the retaining ring in the housing.
The pump through shaft, motor output shaft, displacement
control shaft, and brake shaft seals may be replaced by
following a similar procedure as outlined for the pump input
shaft seal. These seals are not held in position by a retaining
ring. The replacement of axle shaft seals requires the
removal of the axle mounting horn while the replacement of
the seals on pump through shaft and the motor output shaft
requires removal of the BDU-10L from the 210-3000 axle
assembly.
Minor Repairs
Charge Check Valves
Remove the check valve plug with a 1/4" internal hex
wrench.
Remove the check valve spring and check ball (or poppet)
from the center section.
CAUTION: Do not allow the check ball to fall into the
closed loop passages in the center section. Removal
may be difficult but can be accomplished with a magnet,
or by removing the plug from the end of the center
section. Do not allow contaminants to be introduced to
