johnj92131 Posted December 24, 2013 Share Posted December 24, 2013 Over the last several weeks I have swapped several gauge clusters in the Comanche while the truck sits in the garage. Need some help identifying where the tach in the first 3 picturs came from. And the item in the 4th picture is a left over part, but I am not sure where it came from. Any help will be appreciated. http://www.flickr.com/photos/18856762@N05/?details=1 Link to comment Share on other sites More sharing options...
Jeep Driver Posted December 24, 2013 Share Posted December 24, 2013 The pic of the two together....... The top one looks like a mid 80s AMC tach. The lower looks like a late 80s through 90s Chrysler tach. I'm no expert........just a guess base on what I've seen. Link to comment Share on other sites More sharing options...
johnj92131 Posted December 24, 2013 Author Share Posted December 24, 2013 Should have been more specific. Yes, the top tach is an AMC vintage - either 1985/6 or 87. Bottom tach face is 91+ H.O. I am wondering if the 5500 redline is a clue as to the engine? Is it the 4 cylinder or the V6? Most renix 6's I have noticed had a 5K red line (at least the later renix engines). Notice also that the top tach face has a larger "sweep" than the later tachs. Want to use the earlier tach in a 6 guage HO cluster with the matching blue face guages. I have the late model blue face speedomoter and matching blue face small guages to fit the HO cluster. Just need the tach to match. The pic of the two together.......

87MJTIM Posted December 24, 2013 Share Posted December 24, 2013 The top tach looks like the one I just swapped out of my '87. The lower one is the one I just put in (along with all the other gauges.) I don't know the year, however. Link to comment Share on other sites More sharing options...
johnj92131 Posted December 24, 2013 Author Share Posted December 24, 2013 87MJTIM, Do you have some pictures of the one you just swapped out you could send me? Might even want to buy your old one if it is forsale. johnj92131@yahoo.com Thanks, The top tach looks like the one I just swapped out of my '87.

Eagle Posted December 24, 2013 Share Posted December 24, 2013 The "early" tach was used from '84 through '87. The newer style, with the single digits, "fat" lines, and ticks only at the 250 marks, was introduced with the 1988 model year. I don't have a clue what that "leftover" part is.

johnj92131 Posted December 24, 2013 Author Share Posted December 24, 2013 Thanks Eagle! Next step is to test the early tach and see if it works. Are the rivets used on all the early tachs???? Anyone know? The "early" tach was used from '84 through '87. The newer style, with the single digits, "fat" lines, and ticks only at the 250 marks, was introduced with the 1988 model year.

dave92cherokee Posted December 24, 2013 Share Posted December 24, 2013 That leftover part looks like the contact and plug from a connector like they use in weather pack connectors. Link to comment Share on other sites More sharing options...
