Hour meter repair?

[Happy Gilmore]

My thought was since the tachometer works the cable must be ok?

I’d say you’re correct.

I had the same problem with my 1715 and after my research it was cheaper to just replace with new. The plastic gears that drive the hour meter wear out and most shops won't replace them or parts were not available. I checked my old receipt and I replaced mine 13 years ago and the cost was $130 from the dealer.

I think that OEM mechanical hr meter is calibrated to register 1 hr @ rated 450 PTO rpm. I hardly ever run my rig at 450 pto rpm or 2400 engine rpm unless I need it, so it will take me more seat time than one hr for the hr meter to reflect 1 hr. While in college I had an issue with my speedometer so I bought a cheap tach, calibrated speed based on RPM and used it for many years. Of course , I had an ignition system with gasser to get a signal for the Tach. We all know that diesel does not have electrical ignition.
