firenut Posted December 13, 2020 Share Posted December 13, 2020 I have now replaced the RPM Guage cable on my CF 3 times. Each time it works fine for about two hours and then the tang breaks off in the Guage itself. I have replaced the guage, and obviously the cable. Any ideas what could be causing this??

mrgumby Posted December 13, 2020 Share Posted December 13, 2020 (edited) Did you just replace the inside drive cable or both the drive cable and the housing for the cable I always put a little oil or light grease in the cable housing Edited December 13, 2020 by mrgumby Quote Link to comment Share on other sites More sharing options...

I am guessing there is a process for this but I can't find anything that makes sense... Quote Link to comment Share on other sites More sharing options...
KKERGALL Posted December 14, 2020 Share Posted December 14, 2020 I think there was an adapter they used for tack cable at engine 119AX5800 I think that was the number? Maybe that is binding up? Quote Link to comment Share on other sites More sharing options...
Freightrain Posted December 15, 2020 Share Posted December 15, 2020 Just checking...is it the correct tang on the cable? There are various sizes and that cause issues.

mowerman Posted December 20, 2020 Share Posted December 20, 2020 The more I think about it it seems like some of them had some sort of a reduction gear unit between the cable and the gauge .... bob Quote Link to comment Share on other sites More sharing options...
