Drive System
Maintenance
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 115-136 N-m
(85-100 ft-lb ) after 1-4 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 for End-play in the
Planetary Drives
Service Interval: Every 400 hours
There should be no end-play in the planetary drives/drive
wheels (i.e., the wheels should not move when pulled or
pushed in a direction parallel to the axle).
1. Park the machine on a level surface, lower the cuting
units, stop the engine, and remove the key from the
ignition switch.
2. Chock the rear wheels and raise the front of machine,
supporting the front axle/frame on jack stands.
DANGER
A machine on a jack may be unstable and slip
off of the jack, injuring anyone beneath it.
• Do not start the engine while the machine
is on a jack.
• Always remove the key from the ignition
before getting off of the machine.
• Block the tires when you are raising the
machine with a jack.
• Support the machine with jack stands.
3. Grasp one of the front drive wheels and push/pull
it toward and away from the machine, noting any
movement.
1. Front drive wheels
4. Repeat step 3 for the other drive wheel.
5. If either wheel moves, contact your Toro Distributor
to have the planetary drive rebuilt.
Checking the Planetary Gear
Drive Oil
Service Interval: Every 400 hours
Check the oil level after every 400 hours of operation. Use
high quality SAE 85W-140 wt. gear lube as a replacement.
1. With machine on level surface, position the wheel so
one check plug (Figure
and the other is at 3 o'clock position.
1. Check/drain plug (2)
2. Remove the plug at the 3 o'clock position
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. Re-install both plugs.
5. Repeat steps 1 through 4 on the opposite planetary
gear assembly.
