About This Product
If you're maintaining a Kubota compact excavator, especially models like the KX040-4 or the KX121-3 series, here's a part you might need.
This is a brand new front idler from Ahearn, designed specifically for the rubber track undercarriage on these machines.
It's an aftermarket replacement, so it's built to get you back to work without the dealer price tag.
It's brand new, still in the original packaging, and ready to install.
The manufacturer part number is RD158-21302, which crosses over to fit models like the KX121-3, KX121-3S, KX121-3ST, and the KX040-4.
The idler is the wheel at the front that guides the track and keeps tension, so when it wears out, your track can start to wobble or come off.
Replacing it is key to keeping your undercarriage healthy.
It's a sturdy piece, made to handle the tough conditions these machines work in.
