B1B Keven Posted July 16, 2017 Report Share Posted July 16, 2017 I asked Mark and he thought it's for a big truck? Came attached to a speedometer. A speedometer cable can be attached to it also. Quote Link to comment Share on other sites More sharing options...
John Rogers Posted July 16, 2017 Report Share Posted July 16, 2017 (edited) It looks like it could be some sort of governor part or component.Possibly a mechanical speed sensor of sorts . John Edited July 16, 2017 by John Rogers Quote Link to comment Share on other sites More sharing options...
JBNeal Posted July 16, 2017 Report Share Posted July 16, 2017 maybe it has something to do with speedometer adapter when using a 2spd rear axle...? see 21-86-5 in parts manual 3 Quote Link to comment Share on other sites More sharing options...

A speedometer cable can be attached to it also it is. for adapting the speedo reading in a truck with a 2-speed rear. vacuum operated. that way the reading is correct when the gears are split.
