Jrags Posted November 30, 2023 Report Share Posted November 30, 2023 Google Bard says I need a 38" cable with "right lay" I can understand the 38" but I can't understand how a tach cable has preferred twist direction. Doesn't the spline inside just float freely and will turn which ever way the engine connection turns? So they how is there even such a thing as "lay?"

kerry Posted November 30, 2023 Report Share Posted November 30, 2023 I sent my old cable to this shop and they made one up for me that works great. https://www.texasindustrialelectric.com/speedo.asp Previously I bought one from Spruce and it did not work.

The lay is important because you want the cable to tighten with rotation rather than unwind. Are you sure that you need a new cable? Often the problem is that they're running dry and need some speedometer cable lube applied. 1 1 Quote Link to comment Share on other sites More sharing options...

cliffy Posted December 1, 2023 Report Share Posted December 1, 2023 Any old time speedometer shop can make them up Of course that was decades ago when we had mechanical speedos :-) Same as a speedometer drive cable in classic cars Quote Link to comment Share on other sites More sharing options...
