Unless you are a VERY gifted electronics repair technician, there aren't any serviceable parts inside the
instrument cluster other than some incandescent bulbs for cluster illumination & warning lights.
The BX 2360 instrument clusters are obsolete, and have been replaced with newer part numbers.
I guess it is remotely possible you may stumble on a cracked solder joint or corroded connection,
but generally speaking, if the signal from the alternator is reaching the instrument cluster,
then the instrument cluster will require replacement.
As far as replacing only the hour meter/tachometer (if that is your problem) there are no parts anywhere.
I recently bought a used BX 2370, and noticed on my pre-purchase inspection that the hour meter DID operate correctly, and the tachometer DID NOT operate at all. The signal from the alternator obviously was reaching the instrument cluster as the hour meter operated, and the signal from the alternator splits
inside the cluster and does it's thing for the tachometer/hour meter.
In my case, I had to assist the selling dealer with diagnostics, as they didn't understand the correct operation of the entire system. They tried bolting on a new alternator, and replaced the battery.
When I printed out the wiring schematic and visited with the Service Manager and showed him on the schematic where the signal wire (from the alternator) splits inside the cluster, and each "leg" of that circuit goes to the tachometer and hour meter, he reluctantly agreed that the BX 2370 needed a new instrument cluster.
There are new part numbers for new replacement instrument clusters direct from Kubota.
A new cluster will cost you about $700 for the part, excluding labor. (if it's repaired at a dealership)
Tell them there is a TSB (technical service bulletin) from Kubota with part numbers and repair procedures. The replacement clusters ARE tractor model specific.
BX 1860 takes one part number, BX 2360 & BX 25 take another part number, and BX 2660 uses another besides.
Visually, the replacement instrument clusters are strikingly visually different from the original.
No more little LCD display for hours/tachometer.
The replacement clusters are at zero hours when they arrive.
For your machine, you need to measure that frequency/tach signal wire coming from the alternator at the plug on the back side of the cluster. If you have the signal there, you need a new instrument cluster.
Tractors stored outside in the weather get rain/melted snow inside the cluster and then they die.
I don't know the storage conditions for my BX 2370 before it was traded in, but my educated guess is
that it was stored outside, perhaps partly under cover.
(mower deck rust, but paint is not faded to Kubota pink)
I do know it sat outside at the selling dealership from about June 2024 until I bought it
in late February 2025. My salesman told me that the dealership service department charged the sales department retail labor rates for used machines service and repairs, and that the dealership parts department charged retail prices for the parts for repairs for used equipment.
I had added a note on the sales contract that the tachometer would be repaired before I received delivery of the used BX 2370, before signing the sales contract. They called and asked me if they could knock off a couple hundred dollars on the price and deliver the tractor with the tachometer inoperative.
I told them replace the instrument cluster, or tear up the sales contract.
This was from doing some prior investigating on the cost of the new cluster and replacement labor.
Ultimately they did replace the instrument cluster, the tachometer and hour meter work fine now.
I store the machine inside and out of the weather. When the machine mows grass in dry dusty conditions I will actually wash the dust & dirt off the machine occasionally, and I take great care keeping water away from the instrument cluster. In my non professional opinion, water intrusion inside Kubota instrument clusters is the biggest/largest contributor to premature instrument cluster failures.
I don't think the selling dealer made much money on selling me the used BX 2370 because the dealership had to eat the cost of the cluster replacement and labor.
After the machine got several months of repairs/upgrades/modifications work at my shop at my home and it proved to be the low hour reliable machine that I hoped it would be, I drove back up to the selling dealership and gave the salesman a $50 gift card, I was fairly certain his commission check needed a bit of padding.
