0000001801 POTENTIOMETER ADJUSTMENT

Potentiometer adjustment
1. Applied voltage: Vi
2. Boost pressure = P1kPa {P2 mmHg}
3. Set the control lever at the adjusting point. Position the dummy bolt against the lever and fix.
4. Assemble the potentiometer to obtain output voltage V1 (V) at the fixed position.
5. After mounting the potentiometer, remove the dummy bolt.

This chart assumes 5 mpg (2.1 km/L). Your distance maintenance intervals may need to be adjusted if actual fuel consumption differs from the average fuel consumption Caterpillar considered.Example: Your 3406B rated 425 hp (317 KW) at 2100 rpm is averaging 4.5 mpg (1.9 km/L) due to high load factor operation. The engine consumes 2500 gallons (9500 L) of fuel to travel 11,250 miles (18 000 km). PM Level 1 should be performed at every 11,250 miles (18 000 km) instead of 12,500 miles (20 000 km) shown on the schedule.1Experience has shown that maintenance intervals are most accurately scheuled on the basis of fuel consumed. Rated engine speed and load factor are also important for some components. However, Caterpillar recognizes that the distance (odometer) interval is most commonly used to schedule maintenance for on-highway vehicles.
