Used 1994 – 1999

Lubrication SAE 10W-30 API Service Classification SH or higher. Alternate oil: A

synthetic oil (5w50 or similar viscosity range) may be used in place of SAE 10w30. This will permit an increase in the maximum operating temperature of approximately 18°F (10°C).

Oil Capacity 3.5 qt. (3.3 liter)

Oil Level Check when transaxle is cold. Oil should be checked at the reservoir cup, located under the

front hood, on the panel support; oil level should be at the cold mark.

Fluid Change The transaxle is factory filled and does not require regular oil changes.

SPECIFICATIONS

Torque Specifications

Recommended fastener torque values are listed in the following tables. For critical applications, as determined by Toro, either the recommended torque or a torque that is unique to the application is clearly identified and specified in the service manual.

These torque specifications for the installation and tightening of fasteners shall apply to all fasteners which do not have a specific requirement identified in the service manual. The following factors shall be considered when applying torque: cleanliness of the fastener, use of a thread sealant (Loctite), degree of lubrication on the fastener, presence of a prevailing torque feature, hardness of the surface underneath of the fastener’s head, or similar condition which affects the installation.

As noted in the following tables, torque values should be reduced by 25% for lubricated fasteners to achieve the similar stress as a dry fastener. Torque values may also have to be reduced when the fastener is threaded into aluminum or brass. The specific torque value should be determined based on the aluminum or brass material strength, fastener size, length of thread engagement, etc.

Fastener Identification

Inch Series Bolts and Screws

(A) Grade 1 (B) Grade 5

Figure 1

The standard method of verifying torque shall be performed by marking a line on the fastener (head or nut) and mating part, then back off fastener 1/4 of a turn. Measure the torque required to tighten the fastener until the lines match up.

Greasing and Lubrication

3. One located on the front axle pivot area (1 total) (Figure 4).

Figure 4

Hydrostatic model tractors have one grease fitting on the forward/reverse pedal (Figure 5).

MVC-085X

The machine should be greased every 50 hours or yearly, whichever occurs first. You should grease more frequently when operating conditions are extremely dusty or sandy.

Grease Type: General-purpose grease.

There are 5 grease fittings located in the front axle area:

1. One located on the inside of each wheel hub (2 total).

2. One located on each end of the front axle for the spindles (2 total).

Front Wheel Toe-in

If there is uneven tire wear, lawn scuffing, or hard steering, toe-in may need to be adjusted. The front toe-in measurement should be 1/8” to ¼” (3 to 6mm). This should be checked every 100 hours or once a year, whichever occurs first.

3. Measure the distance between both the front rims at spindle level, in front and rear of the wheels. You can also measure between the tread mold marks if the tires are new (Figure 8).

Figure 8

4. The front measurement should be 1/8” to ¼” (3 to 6mm) less than the rear measurement (Figure 9). If needed, follow the adjustment procedure.

MEASUREMENT:

1. Disengage the PTO, set the parking brake, and turn the ignition key to OFF to stop the engine. Remove the key.

2. Push the front of the tires out to remove normal looseness in the linkage (Figure 7).

Steering Gear

Description

The steering gear assembly is made up of a vertically mounted steering shaft and a horizontal sector gear. The sector gear is adjustable so that excessive backlash play in steering gears can be removed (Figure 21).

2. Position the steering wheel so the tie rods clear the front axle and remove them from the steering arms (Figure 22).
