IH Farms 2 Posted July 10, 2016 Share Posted July 10, 2016 So I had the cable break on me taught no big deal. Went to mack bought a new one $120 later installed it. Monday went to work lasted 8 hrs. So when I got home started cruising Summit Racing's website found an autometer guage and a signal generator that'd screw into the trans. Finally got a chance today to install it real simple and easy had to modify the the generator drive with the stock tang which went well and 5 wires to hook up and route 1 Quote Link to comment https://www.bigmacktrucks.com/topic/45984-electric-speedometer-in-an-rw/ Share on other sites More sharing options...

IH Farms 2 Posted July 11, 2016 Author Share Posted July 11, 2016 Yep it'll be kinda handy to have a trip odometer too Quote Link to comment https://www.bigmacktrucks.com/topic/45984-electric-speedometer-in-an-rw/#findComment-338976 Share on other sites More sharing options...
Freightrain Posted July 11, 2016 Share Posted July 11, 2016 (edited) With all the variations today it is not worth fixing the old cable stuff. I stripped a couple different pencil gears in my triplex and gave up on it. Worked with a member here and made an electronic speedo set up. I machined a reluctor ring and the tailhousing for the pickup. It works great, but not something just anyone can do(unless you have machine shop exp). They now make GPS stuff that is plug/play.

I noticed that after I ordered the unit that still drives off of where the cable went that they have GPS modules that'll drive the speedometer Quote Link to comment https://www.bigmacktrucks.com/topic/45984-electric-speedometer-in-an-rw/#findComment-339048 Share on other sites More sharing options...

Timmyb Posted July 16, 2016 Share Posted July 16, 2016 Does this look like the gadget used? Thats the auto meter one. I have seen Dakota digital do one also.

IH Farms 2 Posted July 16, 2016 Author Share Posted July 16, 2016 This is the one I used had to modify it with an original drive tang. Cut it down and drilled a hole in the middle The speedometer head is autometer part number 1480. Had to calibrate it basically find a measured 2 miles and drive it following the instructions on how to set it up I have a T2100 at the moment want a t2130 Quote Link to comment https://www.bigmacktrucks.com/topic/45984-electric-speedometer-in-an-rw/#findComment-339452 Share on other sites More sharing options...
Timmyb Posted July 16, 2016 Share Posted July 16, 2016 That look like it would fit better in my gearbox. I have a 4 inch extension and then a 90 degree fitting on my cable. Did you fit it in the gearbox or at the 90 degree bend? Thanks a bunch for the link. I've ordered it already.

I put a Speedhut 4" GPS speedo unit in my Marmon,(gauge sizes go up to 5 1/2 inches) A hot lead and a Ground, put the GPS sending unit top center of the dash and done.No cables adaptors and ratio figuring. Customized the gauge at the factory to match the other gauges in the dash and even added MARMON TRUCKS to the face at no cost. $279 free shipping and a lifetime garrentee on the unit 1 Quote "OPERTUNITY IS MISSED BY MOST PEOPLE BECAUSE IT IS DRESSED IN OVERALLS AND LOOKS LIKE WORK" Thomas Edison “Life’s journey is not to arrive at the grave safely, in a well preserved body, but rather to skid in sideways, totally worn out, shouting ‘Holy shit, what a ride!’” P.T.CHESHIRE Link to comment https://www.bigmacktrucks.com/topic/45984-electric-speedometer-in-an-rw/#findComment-339483 Share on other sites More sharing options...
mmaupin Posted July 16, 2016 Share Posted July 16, 2016 Yes, the GPS speedo's are the best thing going. Have a look at http://www.speedhut.com/gauges/Speedometers/?catid=f8. They will even set the mileage to match your old odometer. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/45984-electric-speedometer-in-an-rw/#findComment-339485 Share on other sites More sharing options...
