OIL, FILTER AND LUBRICATION INFORMATION
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
transmission oil every 100 operating hours. Remove firewall
to access the drain plug located at the bottom of the trans-
mission. 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
meshing 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
failure.
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 assem-
bly attached to the carburetor.
Wash and oil the precleaner after every 25 hours of opera-
tion 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
components, refer to the air cleaner section of the engine
owner’s manual.
6.3.2 Fuel Filter
All models of the ARGO are equipped with an in-line fuel
filter (ARGO Part No. 125-64). The fuel filter is located in
the fuel hose, next to the fuel tank.
Replace the fuel filter after every 250 hours of operation or
once a year. To replace the filter, loosen the gear clamps
with a slot 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
engine and check for fuel leaks.
6.3.3 Oil Filter
During the initial engine break-in period, change the oil fil-
ter (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
gasket with fresh engine oil. Screw the filter on by hand un-
til the gasket contacts filter adapter. Tighten 1/2 to 3/4 turn
more. Start and run engine to check for oil leaks. Stop en-
gine 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
3. Idler Chains
2. Drive Chains
4. Bearings
Use the recommended lubricants listed in this section and
carefully observe the recommended lubrication intervals.
WARNING
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, di-
recting the spray onto the spring, bushing and the sliding
areas of the cam pulley and the fixed cam where the cam
shoes make contact. (See Figure 6-5).
