0000001801 POTENTIOMETER ADJUSTMENT

Adjustment of the potentiometer
At pump speed N1 and a control lever position a from idle (gap L1), measure the injection quantity and convert it to a voltage value. Then adjust the potentiometer.
Voltage conversion formula: V+-0.03 = 0.044Q+2.07
A:Potentiometer performance standards
C:Position of the control lever
C1:Idle
C2:Full speed
V:Potentiometer voltage
E:Standards for the potentiometer's ON - OFF switch
B:Conversion point
B1:OFF-->ON
B2:OFF-->ON
D:Lever opening (from idle)
Vi:Applied voltage
F:Connecting diagram for the potentiometer
G:Output when (2) and (3) connected.
H:When (4) or (6) connected: switch OFF to ON.
I:When (4) or (5) connected: switch ON to OFF.

Information:
1. Remove the bolts that hold timing gear case cover (1) to the timing gear case. Remove the timing gear case cover.
Later type crankshaft front seals (with protruding dust lip) do not use a slinger. Seal damage can occur if a slinger is used.
2. On earlier models, remove slinger (2). 3. Remove seal (3) from timing gear case cover (1).Install Timing Gear Case Cover
*New, improved crankshaft front oil seals have a dust lip protrusion molded on to the front of the seal. The centering tool (PD162) must be reworked as shown in this illustration to prevent damage to this dust lip when the new type seal is installed. 1. Put timing gear case cover (1) in position with a new gasket. Install the bolts and lockwashers that hold it, but do not tighten them at this time. Use tool (A) to properly locate the timing gear case cover with respect to the crankshaft.2. Install tool (A) over the crankshaft and into the timing gear case cover seal bore. Hold tool (A) firmly in the timing gear case cover. Tighten the bolts that hold the timing gear case cover.
Washer (2) replaces the slinger, which is not used on later type seals with protruding dust lip.
3. Install washer (2). 4. Put seal (3) in position in the timing gear case cover. Install the seal with the lip toward the crankshaft gear. The seal surface must be clean and dry. Do not handle the lip of the seal.5. Use tool (A) and a soft hammer to install seal (3). Install the seal until it is 3.17 mm (.125 in) below the surface of the timing gear case cover.End By:a. install crankshaft pulleyb. install fan assembly
