Checking/Adjusting Drive Chain - Toro Wheel Horse 8-25 Operator's Manual

Checking/Adjusting Drive
Chain
The drive chain must be adjusted to maintain 1/8 of
an inch deflection at mid span between transmission
and differential sprockets. Check chain deflection
after the first 5 hours of operation and after every 25
hours of operation.
1. Remove two screws securing chain cover to rider
chassis and lift off chain cover (Fig. 22).
IMPORTANT: If chain is worn, loose or
adjusted incorrectly, chain will make a
"popping" sound as it moves over the
sprockets, which indicates chain needs
adjusting to prevent sprocket damage. If
assistance is needed, contact your local

2. Check deflection of drive chain by lifting up and
pressing down on chain with moderate pressure
at mid span (Fig. 23). There should be 1/8 of an
inch (3 mm) total deflection (Fig. 24). If
deflection is not as specified, an adjustment is
required—steps 3-13.
1. Drive chain
IMPORTANT: To adjust drive chain, the
rider must be tipped on its rear end. Before
the rider is tipped, drain all gasoline from
fuel tank and oil from crankcase. Also remove
the battery so acid does not spill onto the
rider. (ALL BAGGING ATTACHMENTS
MUST BE REMOVED BEFORE TIPPING
RIDER.)
3. Drain gasoline from fuel tank: refer to Draining
Gasoline From Fuel Tank, page 34.
4. Drain oil from crankcase: refer to Changing
Crankcase Oil, page 29.
5. Remove battery from chassis: refer to Removing
392
the Battery, page 34.
6. Shift transmission into 1st gear and engage the
parking brake. Tip rider onto its rear end so
chassis is on top of 2" x 4" wood blocks. Wheels
must be off the floor so axle can be moved.
