Changing The Gear Case Oil And Filter - Toro 09802 Operator's Manual

1. Spark plug
3. Pull the wires off of the spark plugs and remove the
plugs from the cylinder head.
4. Check the condition of the center and side electrodes
to determine the operating temperature of the
engine.
• Light brown insulator tip indicates correct spark
plug and heat range.
• Black or oily insulator tip indicates an excessively
rich fuel mixture, possibly caused by a dirty air
cleaner element or a carburetor that is set too
rich.
• Light gray or blistered-white insulator indicates
overheating caused by a lean carburetor setting
or incorrect spark plug (heat range too high).
5. After setting the air gap at .040 in., install the spark
plugs in the cylinder head. Tighten the plugs to
18-22 ft.-lb. (24-30 NVm). Push the wires onto the
spark plugs.
6. Lower the hood and secure the latches.
Changing the Gear Case Oil
and Filter
Service Interval: After the first 25 hours
Every 200 hours
Change the hydraulic oil and filter initially after 25 hours
of operation; thereafter change them every 200 hours
of operation.
Important: The gear case oil and filter must be
changed immediately when any contamination,
sludge, water or condensation appears.
1. Disengage the hood latches and open the hood.
Figure 28
2. Place a drain pan under the bottom of the gear case.
Clean the area around the drain plug (Figure 29).
Note: When draining the oil, use a funnel or some
type of channel to divert the draining oil away from
the machine components and into a drain pan.
1. Drain plug location
3. Remove the drain plug and allow the oil to flow into
a drain pan. After the oil has drained, install the oil
drain plug.
4. Remove the oil filter (Figure 30), mounted below
control panel base, and discard the filter. Thoroughly
clean the filter mounting surface and make sure that
a new gasket is installed in the new filter.
1. Oil filter
5. Fill the new filter with new Mobil DTE 26 hydraulic
oil or equivalent oil. Apply a thin film of clean oil
to the filter gasket.
6. Install the new filter by hand until the gasket just
touches the mounting surface, then turn it an
additional 1/2 to 3/4 turn.
7. Remove the filler cap and add approximately 4-5
quarts of Mobil DTE 26 hydraulic oil or equivalent
oil to the gear case reservoir. Install the filler cap.
