Operations

The Traction Motor Speed Probe generates speed pulses when teeth on the pinion bearing retainer in the traction motor pass by the sensor. The sensor should be threaded into the probe mounting wall until it bottoms out. The air gap between the sensor and the teeth on the pinion bearing retainer should be 0.025" to 0.045". The resulting signal is routed to the appropriate devices for processing.

Note: The following information is present on the Cable Label: · · · · Q-Tron Part No. Customer Part No. (if required) Serial No. Made in Canada indicator

Mounting Instructions

Mount the Traction Motor Speed Probe on the camshaft side of the gear. Tightening torque must not exceed 15.1 ft/lb when applied to hex portion of shell.
