Hour meter adjustment

[Cami]

I think kennyd is on the mark with the suggestion of simply mentioning it in the service records; no need for fuss.

As for tachometers and diesels, if your engine doesn't have a signal generator, you can get an aftermarked one to run off your alternator. I've only read about them and never used one myself.

$31 from Messics for a new one. PN for a RTV900T is K2561-62510, others may be the same.
Kubota RTV900T Parts Diagrams look under Electrical System > Panel Switch. It is #080

Tiny Tach runs off the pulses of your fuel injector on a diesel. It provides a number of cool features...

Welcome To Tiny-Tach. Small and economical tachometers for gas and diesel engines.

I bought my tractor with the hour meter showing around 200. It showed up (cross country) with a dead battery and 300 hours on the meter... Took a while to figure that one out...

Not the same machine but my tach and hour meter work off a sensor mounted on the bell housing. Its like a pickup on a small B/S lawnmower engine. It has a spot on the flywheel that I guess has a magnet. As the flywheel spins it cross the pickup and sends a signal to the tach which has the hour meter in it.

In the scheme of things that extra 50 hours means squat. Just record it in your service manual as an opps, and chalk it up to a lesson learned.

If you keep the machine to the end of its useful life, and take care of it you will be passing it down to your kids or grand kids. So looking at it that way what is 50 hours, a weeks worth of "true" work?

No big deal in my opinion......

Won't work on a diesel.

This is the one that does.

My JD4310 uses a solid state hours meter. LCD display that sunlight destroys. The hours reading is stored in a memory chip. Hopefully the printed circuit board has reverse polarity protection - else the smoke would come out of the chips if jumped off with reverse battery.

DO NOT try and run an electronic hour meter with reverse power. Mechanical - maybe at your own risk.

I did find a supplier for the LCD in Chicago - $13 vs $$$ from JD for a new cluster. Does require solder and de-solder skills.

I believe I would make a notation in the owner's manual and go on.

Just a follow up on this issue that might help someone else with the same problem. After it happened 2 more times (now my meter reads 120 hours more than actual time), I needed to figure out what was going on. I felt sure I was turning the key completely off, but I would still come back and find it with the key in the "on" position with my hour meter racking up time. What I discovered was that the slotted rubber boot in the ignition switch was cocked to the right (about a 2 o'clock position). It was not far enough off that the key couldn't be inserted, but when the key was turned far left (off position) the rubber boot was exerting pressure on the key in a clockwise direction... apparently after a period of time it would actually cause the key to turn to the "on" position. I turned the boot slot to a straight vertical position, and the problem has gone away.

I still don't understand why Kubota wouldn't install the hour meter so that it would only record when the motor was actually running... poor design in my estimation.

Kioti is the same way, I'd rather have a cable drive tach, they only read true hrs at pto speed. This would make a significant difference (fewer hrs.) for someone like me who rarely runs at pto speed. I've always wondered what affect this has with the service intervals. Manufacturers recomend to change fluids at the first 50 hrs on both cable drive and digital hr meters. If you installed a digital hr meter on a tractor that already has a cable drive hr meter, the digital guage will show 50 hrs. much sooner than the cable guage. (unless the engine is ran at pto speed the whole time) So are those of us who have digital hr meters servicing our machines too often or are those with cable drive hr meters going too long in between services?

Hi I'm a new member to your forum. I have had my RTV for 15 months now (love it more everyday). I have been reading your forum for a year and a half. I find it very very interesting and informative. I think I have an answer to one of you guys questions. Running the hour meter only when engine is running. Two different times my key got left on adding 4 hours to my meter! Here is what I did.

1. Make up new 6" long wire with fuse holder+1/4 amp fuse, with femalespadeconnector on one end
On back of hour meter disconnect (red/yellow) wire and leave it disconnected
On the back of the Battery emblem is a lightsocket, there is a (white/red) wire (mine is marked #2) splice the new wire to this wire and connect it to the empty terminal on the hour meter

I have run mine this way the last 20 hours with no problems.

The #2 wire (white/red) on battery indicator light,comes from the alternator to the battery indicator light and is positive 14 voltsonly engine is running.



I did this to my 9 and it fixed the problem. Ran up 8hrs unexpectedly.
