Not the fan belt by any chance? I had Ltd of trouble with my belt with a new CX2510. I purchased a 25-7400 belt from NAPA and had no more trouble with the tach which is driven by the speed of the alternator.
I have a CX2510 doing almost the same. It started out that way but now it clicks at a high frequency as the motor is trying to turn about a degree each click. I brought the starter to a shop and he reported it checked out fine.
If I get it figured out I will report back here. I’ve seen post...
It’s in Iptman’s picture. Your HOSES replace the long pipe from the loader control valve to the transmission under the seat, the third function control valve is placed essentially in the middle of the old hard pipe. Hopefully this helps.
I can try to add more pics from what Iptman already...
Unless you seen them in person, my opinion is they are not that far apart in size. That 2610 maybe more handier in the future. I now wish I would have gotten the 2610.
Your belt maybe slipping and not driving the alternator that runs the tach. Check the tension, I had alot of trouble with mines. I think the Napa replacement is 25-7400. That may not be the exact fit but worked. It maybe best to get the Kioti belt but I sincerely like to be hardheaded.
I seen a video on YouTube where the owner used a shop vac on the fill to keep oil dump to a minimum while he changed the filters.
Also another video show someone accepting the new cx and the dealer told him just wait till 100hrs and do oil and filters then regular maintenance there after.
