Changing The Gear Case Oil And Filter - Toro 09802 HydroJect 3010 Operator's Manual

2. Clean the area around the spark plugs (Fig. 25) so that
dirt does not fall into the cylinder when the plugs are
removed.

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).
Important
A cracked, fouled, or dirty spark plug must
be replaced. Do not sandblast, scrape, or clean the
electrodes by using a wire brush because grit may release
from the plug and enter the combustion chamber, resulting
in engine damage.
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 N⋅m). Push the wires onto the
spark plugs.
6. Lower the hood and secure the latches.
Changing the Gear Case Oil
and Filter
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.
2. Place a drain pan under the bottom of the gear case.
Clean the area around the drain plug (Fig. 26).
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.

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 (Fig. 27), 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.

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.
