Traction Drive Chains - Toro 22304 Operator's Manual

Traction Drive Chains

Checking the Tension
Check the drive chain tension before using the
traction unit for the first time and every 50 hours of
use thereafter.
Drive chains should have about 1–1/2 to 2–1/2 inches
of slack between the bottom of the chain guard and
the bottom chain span when the top chain span is
pulled tight. Use the following procedure to check
the tension:
1. With the bucket installed, lower it into the
ground until the front tires are off of the ground.
2. Turn the ignition key to "OFF" and remove it.
3. Turn the front wheel forward on one side of the
traction unit until the top span of the drive chain
is tight.
4. Measure the distance between the bottom of the
chain guard and the lower chain span (Fig. 18).
If the slack in the chain is not within 1–1/2 to
2–1/2 inches, adjust the tension (refer to
Adjusting the Tension).

IMPORTANT: Under sandy conditions, sand
can build up on the sprockets. This enlarges the
sprocket and the chain tightens. Under these
conditions the chains should have 2–1/2 to 3–1/2
inches of slack between the bottom of the chain
guard and the lower chain span.
5. Repeat steps 3 and 4 for the other drive chain.
6. Start the engine and raise the bucket to return the
front wheels to the ground.
Adjusting the Tension
1. With the bucket installed, lower it into the
ground until the front tires are off of the ground.
2. Turn the ignition key to "OFF" and remove it.
3. Remove the chain guard (Fig. 18).
4. Loosen the jam nut on the chain tensioning bolt
and loosen the bolt (Fig. 19).

5. Turn the front wheel backward on one side of the
traction unit until the lower span of the drive

the top span and the mud guard (Fig. 20).
