ELBOW 4M8973 - Caterpillar

The new 9W6370 Electronic Speed Switch Adapter Cable, when used with the 8T5200 Signal Generator-/Counter Group, allows the 8T5201 Signal Generator-/Counter to perform functional checks and calibration of engine electronic speed switches. The new electronic speed switch adapter cable is approximately 21" long, and is available from the Parts Department.
The 9W6370 Electronic Speed Switch Adapter CableThe cable connects to the 8T5197 Calibrator Cable from the 8T5200 Signal Generator/Counter Group. These two cables are then used to connect the "CAL. OUT" on the 8T5201 Signal Generator/Counter to the magnetic speed pickup input terminals on the two and three element electronic speed switches. The 8T5200 Signal Generator/Counter Group can then be used to send a speed signal to the electronic speed switch in place of the magnetic pickup: to check and or adjust the overspeed setpoint, crank termination, and oil step latch functions.
The 8T5200 Signal Generator/Counter Group cannot be used to check the four element electronic speed switch that has reverse rotation detection, and uses a Hall Effect Sensor for speed detection.
