  • Proofmeter
  • Can anyone tell me the difference in the two 4 speed proofmeters, I think one of my 8s has the wrong one but not positive.

  • Check the rotation of your tractor cable then check the rotation of your proofmeter. You can use a reversable electric drill to check the proofmeter. Sounds like you may have the one for NAA's and later. The rotation is reversed.

  • The 8N only used one Proofmeter, p/n 8N-17360-A, 50-52. There is a one for the 4-Speed that fits the 600-4000 tractors, p/n C3NN-17360-N, 53-64. You may just have the wrong cable. You need p/n 8N-17365 with the 8N Proofmeter.

  • . Just above the hours counter, the words "Hours at 1580 RPM" appear on an 8N meter and "Hours at 1515 RPM" appear on NAA meter.

  • Good simple answer! Also it might be good to know that if NAA meter is installed on 8N, it will read 56% too high or 1.56 X actual rpm. And for the NAA owners, if 8N meter installed on your NAA it will read only 64% of actual rpm.

  • That was what made me wonder what was up I felt it was reading to high, checked my jubilee and it is the same one they are both different than my other 8n. Thanks for the info.
