jimoshel Posted July 30, 2011 Share Posted July 30, 2011 Related to a previous post on larger tire, speedometer off. Any body know, or remember what these are? Link to comment Share on other sites More sharing options...
jeepsouth Posted July 30, 2011 Share Posted July 30, 2011 Some sort of vehicle speed sensor to correct for the tires/gears? :dunno: Link to comment Share on other sites More sharing options...
btm24 Posted July 30, 2011 Share Posted July 30, 2011 Speedo gears for inside of the tranny for when you upgrade tire size but not gear ratio right? Brandon Link to comment Share on other sites More sharing options...
jimoshel Posted July 31, 2011 Author Share Posted July 31, 2011 ^ You gottem. Back in the old days, pre electronic, that would fit between the transmission and speedo cable.Didn't have to disassemble the the tranny. Remove the cable, remove the drive gear. You could buy just the converter already set up to your specs, or you could get the complete kit, which consisted of the housing body, the drive gear, which mated with the gear on the tranny output shaft, two gears which fit inside the housing and a chart where you dialed in the rear end ratio and tire size. Then read off which gears to put where, There were twenty gears total, all color coded. Link to comment Share on other sites More sharing options...
btm24 Posted July 31, 2011 Share Posted July 31, 2011 Do you have them all? Brandon Link to comment Share on other sites More sharing options...
jimoshel Posted July 31, 2011 Author Share Posted July 31, 2011 Some place. I been cleaning out the garage, storage and throwing away, sorting thru over 50 years of parts, pieces and stuff. When I saw them I remembered the thread on speedo error. Anybody need a tune up kit, points, rotor, capacitor for a 1948 Nash? Rebuilt starter for a '42 Willys? Sorry I got started.

AMC-MJ Posted July 31, 2011 Share Posted July 31, 2011 I'd like to be able to have a correct speedo with 4.10s n 235/75R15s ;) Mike Link to comment Share on other sites More sharing options...
alleydog Posted July 31, 2011 Share Posted July 31, 2011 First thing you have to do is figure out what percent your speedo is off, then there is a ratio number on the little gear box that tells you how much it changes the speed. Link to comment Share on other sites More sharing options...
86FUBAR Posted July 31, 2011 Share Posted July 31, 2011 Ya I remember those , we had those on our old Crown school buses (the bus that looks like a Twinkie) my Ramcharger has one on it but it has a plastic housing not the aluminum ones . We still have a small box of those things hanging around work and they are still readily available from our local Truck Parts store but they are kinda pricy IIRC.
