Frequently Asked Questions

When should I replace the belt on a Kubota mini excavator?

Replace the belt when it shows cracking, glazing or fraying. A worn alternator or fan belt can fail in the field and leave the alternator unable to keep the electrical system charged. Broken Tractor carries replacement alternator V-belts, fan belts and alternator and fan drive belts for Kubota compact excavators.

What alternator belt fits a Kubota KX040-4 excavator?

The Alternator V-Belt with Kubota part number RD158-47920 fits the Kubota KX040-4. It drives the alternator and keeps the charging system working on the machine. Matching the RD158-47920 number on your old belt or in your parts book is the easiest way to confirm the fit.

Which belt fits a Kubota KX080-3 versus a KX080-4?

The KX080-3 uses the Fan Drive Belt with Kubota part number 1G541-97010. The KX080-3T, KX080-4, KX080-4S and KX080-4S2 use the Alternator Drive Belt with part number 1G772-97010. That 1G772-97010 belt also fits the KX057-5, U55-5, and the KX057-4 and U55-4 when equipped with A/C.

What fan belt fits a Kubota KX121-3 or KX161-3 excavator?

The Fan Belt with Kubota part number 15469-97010 fits the Kubota KX121-3, KX121-3S and KX161-3. For the earlier KX121-2, KX121-2S, KX101, KX151, KX91-3S, KH101, KH151 and U35S, Broken Tractor offers the Fan Belt with part number 15471-97010.

How do I make sure I order the right belt for my Kubota excavator?

Match the Kubota part number from your old belt or parts book, and check your model and serial number, because some fitment changes by serial range. For example, the Alternator and Fan Drive Belt 15606-97020 is listed for the KX161-2, with serial-specific fitment noted for that model. Options such as A/C can also change which belt you need on models like the KX057-4 and U55-4. If you are unsure, call (800) 909-7060 and the parts team can confirm fitment.
