CAMSHAFT TIMING CONTROL MOTOR INSPECTION

PROCEDURE

1. INSPECT CAMSHAFT TIMING CONTROL MOTOR WITH EDU ASSEMBLY

   
   
   1. 

      *a

      Joint

      Rotate the joint of the camshaft timing control motor with EDU assembly by hand and check that it rotates smoothly.

      Standard Condition
      The motor rotates smoothly.

      Note

      
      

      • Make sure the contact surface of the camshaft timing control motor with EDU assembly (the surface that contacts the timing chain cover assembly) is free of foreign matter.

      • Do not disassemble the camshaft timing control motor with EDU assembly. If disassembled, replace it.

      • If the camshaft timing control motor with EDU assembly has been struck or dropped, replace it.

      Tech Tips

      The eccentric shaft may feel difficult to rotate due to the spring inside the camshaft timing control motor with EDU assembly.

      If the result is not as specified, replace the camshaft timing control motor with EDU assembly.

2. INSPECT CAMSHAFT TIMING GEAR ASSEMBLY

   
   
   1. 

      *a	Eccentric Shaft

      Rotate the camshaft timing gear assembly eccentric shaft by hand.

      Standard Condition
      The shaft rotates smoothly.

      Note

      
      

      • Do not disassemble the camshaft timing gear assembly.

      • If disassembled, replace it.

      • If the camshaft timing gear assembly has been struck or dropped, replace it.

      Tech Tips

      The eccentric shaft may feel difficult to rotate due to the spring inside the camshaft timing gear assembly.

      If the result is not as specified, replace the camshaft timing gear assembly.

   2. 

      *a	Cutout
      *b	Joint

      Check the joint clearance.

      
      

      1. Using a vernier caliper, measure the width (A) of the cutout of the camshaft timing gear assembly eccentric shaft.

         Standard Width
         5.98 to 6.05 mm (0.236 to 0.238 in.)

      2. Using a vernier caliper, measure the width (B) of the joint of the camshaft timing control motor with EDU assembly.

         Standard Width
         5.90 to 5.95 mm (0.233 to 0.234 in.)

      3. Calculate the clearance by subtracting the width (B) of the joint of the camshaft timing control motor with EDU assembly from the width (A) of the cutout of the camshaft timing gear assembly eccentric shaft.

         Standard Clearance
         0.03 to 0.15 mm (0.00119 to 0.00590 in.)

         Maximum Clearance
         0.7 mm (0.0275 in.)

         If the clearance is more than the maximum, replace the camshaft timing gear assembly or camshaft timing control motor with EDU assembly.
