OIL, FILTER AND LUBRICATION INFORMATION
The transmission oil level should be even with the mark on
the dipstick as shown in Figure 6-4. Add 80 W 90 Gear Lube
HYPOY-C through the transmission oil fill/dipstick hole un-
til the transmission is filled to the correct level. DO NOT
OVERFILL. Replace the dipstick securely.

6.2.2 Changing the Transmission Oil

Change the transmission oil after the first 20 hours of opera-
tion, or after using 2 tanks of fuel. After this, change the trans-
mission oil every 100 operating hours. Remove firewall to
access the drain plug located at the bottom of the transmis-
sion. Drain the transmission oil into a suitable container and
dispose of the oil at a disposal site.
While draining the transmission oil, be sure to clean off any
metal particles that are on the magnet of the drain plug. These
fine metal particles are a result of the transmission gears mesh-
ing during the initial break-in period. Re-install the plug and
tighten it securely.

Refilling the Transmission

Refill the transmission through the oil fill/dipstick hole with
30 oz (.85L) of 80 W 90 Gear Lube HYPOY-C. As you refill
the transmission, check the oil level with the dipstick. Check
that the oil level is even with the mark on the dipstick, after it
has been seated fully in the dipstick hole. DO NOT OVER-
FILL.
Overfilling may result in oil being forced out the breather hole
that could contaminate the brake pads and lead to brake fail-
ure.

6.3 FILTER INFORMATION

6.3.1 Air Filter

All ARGO engines are equipped with a foam precleaner and
dry paper air filter element housed in an air cleaner assembly
attached to the carburetor.
Wash and oil the precleaner after every 25 hours of operation
or more often under extremely dusty or dirty conditions.
Check the paper air filter element every 100 hours of opera-
tion or more often under extremely dusty or dirty conditions.
For instructions to remove, clean and replace the air filter com-
ponents, refer to the air cleaner section of the engine owner's
manual.
SECTION 6

6.3.2 Fuel Filter

All models of the ARGO are equipped with an in-line fuel
filter (replacement fuel filter is ARGO Part No. 125-64). On
Conquest models the fuel filter is located in the fuel hose,
next to the fuel tank. On all other Argo models the fuel filter is
located at the engine.
Replace the fuel filter after every 250 hours of operation or
once a year. To replace the filter, loosen the gear clamps with
a standard screw driver and pull the rubber fuel lines off of
the filter. Install the new filter with the flow arrow pointing
toward the engine. Tighten the clamps securely. Start the en-
gine and check for fuel leaks.

6.3.3 Oil Filter

During the initial engine break-in period, change the oil filter
(Part No. 126-95 for Briggs & Stratton engines and Part No.
127-68 for Kawasaki engines) when the oil is changed. After
that, change the oil filter every 50 hours.
Before installing the new filter, lubricate the rubber filter gas-
ket with fresh engine oil. Screw the filter on by hand until the
gasket contacts filter adapter. Tighten 1/2 to 3/4 turn more.
Start and run engine to check for oil leaks. Stop engine and re-
check oil level. Add oil if required.

6.4 LUBRICATION INFORMATION

6.4.1 General

The following parts and components require regularly sched-
uled lubrication to prevent premature wear and replacement.
1. Driven Clutch
2. Drive Chains
Use the recommended lubricants listed in this section and care-
fully observe the recommended lubrication intervals.
Do not attempt to lubricate the driven clutch while the
engine is running.

6.4.2 Driven Clutch Lubrication

Lubricate the driven clutch every 50 hours with a silicone based
lubricant. Spray the lubricant into the clutch unit, directing
the spray onto the spring, bushing and the sliding areas of the
cam pulley and the fixed cam where the cam shoes make con-
tact. (See Figure 6-5).
