SECTION 3 – LUBRICATION AND MAINTENANCE
3-3
LUBRICATION FITTINGS
NOTE: After every 50 hours of normal operation,
apply a good quality grease to the lubrication
points listed below (refer to the Recommended
Lubricants chart). When operating under
extremely dirty conditions, lubricate more
frequently than every 50 hours.
• Steering Linkage
• Front Axle Pivot
• Power Steering Cylinder
• Pedal Shaft—Clutch & Brake Pedals
• 3-Point Linkage
To lubricate these points:
1. Wipe away all old grease and dirt from the
lubrication fittings to prevent dirt or foreign
material from entering as new grease is
applied.
2. Use a high pressure grease gun to force in
the new grease. Apply pressure until clean
grease oozes from each lubrication point.
3. Wipe away any excess grease.
DIESEL FUEL
• Use clean, quality No. 1 -D or No. 2-D fuel
(ASTM D975).
• Use No. 1-D fuel if the ambient temperature
is expected to be lower than 4°C or if the
tractor is to be used at an altitude exceeding
1524 m.
• Use No. 1-D diesel fuel with a pour point of
at least -12°C below the expected ambient
temperature to prevent fuel flow problems in
cold weather.
• Keep dirt from entering the fuel tank.
• Sulfur content of the fuel should be no more
than 0.5%.
• Sediment and water content should not
exceed 0.05%.
• Minimum cetane number is 40. Low
temperature or high altitude operation may
require use of fuel with a higher cetane
number.
• Use properly mixed winter fuel when
temperatures are extremely cold. In most
areas, diesel fuel is properly blended for
summer and winter grades as ambient
temperatures change. In winter, use winter
grade diesel fuel only. Otherwise, the fuel
may jell and block the fuel system.
Fuel Usage Safety
• UNDER NO CIRCUMSTANCES should
gasoline, alcohol, or gasohol be added to
diesel fuel. These combinations can create
an increased fire or explosive hazard.
• Never remove the fuel cap or refuel the
tractor while the engine is running.
• Never smoke while refueling or anywhere
near fuel.
• When filling the tank, maintain control of the
nozzle.
• Do not fill the fuel tank to capacity. Allow
room for expansion.
• Wipe up spills immediately.
• Always tighten the fuel cap securely.
• If the original fuel tank cap is lost, always
replace it with a SHIBAURA approved cap. A
"will-fit" cap may not be safe.
• Keep equipment properly maintained.
• Do not drive equipment near open fires.
• Never use gasoline for cleaning parts.
