Fuel Filter

1.  Replace the secondary fuel filter (Figure 44) every 800 

hours. Refer to your engine manual for specific details 

to perform this operation.

Figure 44. Fuel Filter

Fuel/Water Separator Primary Filter

1.  Inspect the fuel filter water separator daily. If the fuel 

filter/water separator (Figure 45) has collected a 

significant amount of water and sediment at the bottom 

of the cup, it should be drained off. 

Figure 45. Fuel Water Separator

2.  To remove water and sediment from the cup, place 

any fuel valves to the 

OFF

 position and unscrew the 

cup from the base.

3.  Pour the contents of the cup into a safety container. 

Rinse cup with a mild detergent and reattach cup to 

base.

4.  Return fuel valves to the 

ON

 position.

MAINTENANCE

In-Line Fuel Filter

Replace the engine in-line fuel filter (Figure 46) every year or 

300 hours.

Figure 46. In-Line Fuel Filter

Oil And Fuel Lines

1.  Check the oil and fuel lines and connections regularly 

for leaks or damage. Repair or replace as necessary.

2.  Replace the oil and fuel lines every two years to 

maintain the line's performance and flexibility.

V-BELT

Visually examine the V-belt (Figure 47) and determine if it 

is full of tiny cracks, frayed, has pieces of rubber missing, 

is peeling or otherwise damaged.
Also, examine the belt and determine if it is 

oil soaked

 or 

"

glazed 

" (hard shiny appearance on the sides of the belt). 

Either of these two conditions can cause the belt to run hot, 

which can weaken it and increase the danger of it breaking. 
If the V-belt exhibits any of the above wear conditions 

replace the V-belt immediately.
