If that is the only cluster available, and the pin outs are identical, you have run out of options.
There was a Kubota Technical Service Bulletin for replacing instrument clusters on older BX machines. There were three different part numbers.
1) BX 1860 & BX 1870 - all the 18 hp models.
2) BX 2360 & BX 2370 & BX 25 (backhoe variant) - all the 23 hp models.
3) BX 2660 & BX 2670 - all the 26 hp models.
So there ARE differences inside the cluster, likely the chip calibration for RPM.
But that's just an educated guess
I have a recently purchased BX 2370 that got a new factory instrument cluster as a condition for the purchase back in early spring of 2025.
I do mowing with that machine and wanted to be certain I was running it at the correct RPM.
Harbor Freight has a $35 or so laser/optical tachometer. You stick a piece of reflective tape on the edge of the flywheel. Spin it up to speed and compare the instrument cluster tachometer to the
Harbor Freight laser/optical hand held tachometer.
My new factory instrument cluster was within 100 RPM of the Harbor Freight unit at 3200 RPM.
I can live with that.
If @ white tiger spots this post, perhaps he can comment on the instrument cluster differences.
