     (ii)   Two 12-inch flexible shafts to fit Chrysler speedometer.

     (iii)   One 12-inch flexible shaft to fit Ford speedometer.

     (iv)   One 12-inch flexible shaft to fit older speedometers with 5/8-18 male thread.

 (b)  Periodic testing of speedometer testing equipment. Periodic testing of equipment shall be conducted as follows:

   (1)  Interval. Speedometer testing equipment shall be tested and adjusted for accuracy at least once every 60 days.

   (2)  Forms. A form provided by the Department shall be completed by a certified speedometer inspection mechanic after each periodic test. The form shall be released to the State Police Inspection Station Supervisor or Department representatives, if verification of the test is necessary. A duplicate copy, executed and signed in the same manner as the original, has the same force and effect as the original.

 (a)  Accuracy. A test speedometer shall be tested for accuracy and, if necessary, repaired and adjusted to obtain the greatest possible degree of accuracy. Testing shall include one of the following:

   (1)  A dynamometer test.

   (2)  A Speed-Master Quartz Speedometer Tester.

   (3)  A Stewart-Warner Speedometer Calibrator and required components.

     (i)   It will be necessary to have a measured or surveyed mile laid out and properly marked. If less than a mile, use Table 1:

 Table 1
1 mile or 5,280 feet = 1000 cable revolutions
1/2 mile or 2,640 feet = 500 cable revolutions
1/10 mile or 528 feet = 100 cable revolutions

     (ii)   Check the tires on the test vehicle for proper inflation.

     (iii)   Disconnect the speedometer cable from the back of the speedometer in the vehicle.

       (A)   Connect the speedometer cable to the counter. (S. S. White Mile-O-Meter).

       (B)   Place the vehicle rear wheel centered on line at the beginning of the measured course.

       (C)   Set the counter of the Mile-O-Meter to zero.

       (D)   Drive the vehicle over the measured course.

       (E)   Read the counter and compare it with Table 1.

       (F)   Establish degree or percent of error. In a given measured mile, there should be 1000 cable revolutions. The input speed is slow if less than 1,000. The input speed is fast if more than 1,000.

     (iv)   Disconnect the counter from the speedometer cable on the vehicle.

       (A)   Use the long flexible shaft from the calibrator with the proper 12-inch shaft that permits adopting to fit speedometer head in the vehicle.

       (B)   Proceed to check the speedometer in the vehicle against the master head on the calibrator at 10 mph increments, beginning at 10 to 100 mph, and record the proper information.

     (v)   Disconnect the calibrator flexible shaft from the rear of the speed head in the vehicle and connect the shaft in the vehicle to the speedometer head in same. The speedometer head in the vehicle being tested can also be tested by disconnecting the flexible shaft at the transmission and connecting it to the long flexible shaft from the calibrator. Then proceed as in subparagraph (iv)(B).

     (vi)   Information indicated above is based on United States standard of 1,000 cable revolutions per minute = 60 mph or 96 kilometers per hour.

   (4)  An examination of the speedometer cables to insure that they work freely and without defect or restriction.

 (b)  Forms. The following forms are required:

   (1)  A speedometer testing station shall permanently display a valid Certificate of Appointment, provided by the Department.
