Checking The Torque Of The Wheel Nuts; Checking The Planetary Gear Drive Oil; Changing The Planetary Gear Drive Oil - Toro Groundsmaster 4500-D Operator's Manual

Checking the Torque of the
Wheel Nuts
Service Interval: After the first 8 hours
Every 200 hours
WARNING
Failure to maintain proper torque of the wheel
nuts could result in failure or loss of wheel
and may result in personal injury.
Torque the front and rear wheel nuts to 115
to 136 N-m (85-100 ft-lb ) after 1 to 4 hours of
operation and again after 8 hours of operation.
Torque every 200 hours thereafter.
Note:
Front wheel nuts are 1/2-20 UNF. Rear wheel
nuts are M12 x 1.6-6H (Metric).
Checking the Planetary
Gear Drive Oil
Service Interval: Every 400 hours
Use high quality SAE 85W-140 gear lube as a
replacement.
1. Position the machine on a level surface and
position the wheel so 1 check plug
is at the 12 o'clock position and the other is at
3 o'clock position.

1. Check/drain plug (2)
2. Remove the plug at the 3 o'clock position
71).
Note:
The oil level should be at the bottom of
the check-plug hole.
3. If the oil level is low, remove the plug at the 12
o'clock position and add oil until it begins to flow
out of the hole at the 3 o'clock position.
4. Install both plugs.
5. Repeat steps 1 through 4 on the opposite
planetary gear assembly.
Changing the Planetary
Gear Drive Oil
Service Interval: After the first 200 hours
Use a high quality SAE 85W-140 gear lube as
replacement.
1. Position the machine on a level surface and
position a wheel so that 1 of the check plugs is
at the lowest (6 o'clock) position
1. Check/drain plug
2. Place a drain pan under the planetary hub,
(Figure 71)
remove the plug, and allow the oil to drain.
3. Place a drain pan under the brake housing,
remove the drain plug, and allow the oil to drain
(Figure

(Figure
1. Brake housing
4. When all of the oil has drained from both
locations, install the plug in the brake housing.
5. Rotate the wheel until the open plug hole, in the
planetary, is at the twelve o'clock position.
