Brand: Jones Mechanical Tachometers
These Jones tach cables have Smiths drive inputs. Smiths inputs use a special thread which is about 1/2 inch diameter and accept a flat blade-style drive. Jones tachs use a heavy-duty square SAE drive with a 7/8-18 thread.
These cables include the blade type drive dog on the input end. We also stock the Smiths Drive Dog separately (Part No. 1383) for those cables that do not have the drive dog crimped on.
