2005/01/17 Correction to Engine Speed/Timing Sensor-Calibrate {1912}
Engine:
C15 (S/N: JRE1-UP)
C18 (S/N: WJH1-UP)
Industrial Engine:
C11 INDUSTRIAL (S/N: GLS1-UP)
C13 INDUSTRIAL (S/N: LGK1-UP)
Troubleshooting, RENR5042-00, "Engine Speed/Timing Sensor-Calibrate"

Reference: Disregard the procedure in Test Step 1 that is within the above Troubleshooting, refer to the following procedure:

Test Step 1. Install the Transducer Adapter

  1. Turn the keyswitch to the OFF position.

  1. Use the appropriate engine turning tool to put either the No. 1 piston or the No. 6 piston at top center. Refer to Systems Operation/Testing and Adjusting, "Finding the Top Center Position for the No. 1 Piston".

  1. Refer to Table 1. After the top center position has been located, rotate the crankshaft for the number of degrees that is applicable to your engine model. Be sure to rotate the crankshaft in the direction of rotation that is specified in the Table.

    Table 1
    Crankshaft Rotation    
    Engine Model     Number of Degrees     Direction of Rotation    
    C-10     60     Opposite Normal Rotation    
    C11     75     Normal Rotation    
    C-12     60     Opposite Normal Rotation    
    C13     75     Normal Rotation    
    C-15     60     Opposite Normal Rotation    
    C15     60     Opposite Normal Rotation    
    C-16     60     Opposite Normal Rotation    
    C18     30     Opposite Normal Rotation    

  1. Refer to Table 2. Locate the engine's timing calibration port.

    Table 2
    Location of the Timing Calibration Port    
    Engine Model     Crankshaft Counterweight     Engine Location    
    C-10     8     Right Side    
    C11     8     Left Side    
    C-12     8     Right Side    
    C13     8     Left Side    
    C-15     2     Left Side    
    C15     2     Left Side    
    C-16     2     Left Side    
    C18     2     Left Side    

  1. Remove the plug from the timing calibration port.

  1. Thread the transducer adapter into the port.

Continue to the next Test Step.
