    Frequently Asked Questions

    Fitment, availability, fulfillment, and support for this product

    What drive sprocket fits the Kubota U25?
    This drive sprocket is listed for the Kubota U25 and matches OEM Part #RB511-14432. Before ordering, compare your machine make, model, serial number, and existing part number to confirm the correct undercarriage position and fitment.
    What bottom rollers fit the Kubota U25?
    Matching bottom roller or track roller options for the Kubota U25 include Kubota U25 Track Roller | Part #RB511-21702. Replacing worn rollers before installing new rubber tracks helps keep the undercarriage aligned and reduces uneven wear across the track carcass.
    What front idler fits the Kubota U25?
    Matching front idler options for the Kubota U25 include Kubota U25 Front Idler | Part #RC348-21302. Front idlers guide the track and help maintain proper tension, so inspect the flange, bearing condition, and wear surface before installing new tracks.
    What top roller fits the Kubota U25?
    Matching top roller options for the Kubota U25 include Kubota U25 Carrier Roller | Part #RC411-21903. Top rollers support the upper track path and should be checked for bearing play, flat spots, and uneven wear during undercarriage service.
    What rubber tracks pair with this drive sprockets?
    Matching rubber track options connected to this Kubota U25 undercarriage setup include Kubota U25 Rubber Tracks | 300x53x80 (Part #300X53X80). If you are replacing this part, inspect the full undercarriage so the new component and rubber tracks wear evenly together.
    Should I inspect the full undercarriage before replacing this Kubota U25 part?
    Yes. Sprockets, idlers, rollers, and rubber tracks wear together as a system. Before replacing this part for the Kubota U25, inspect the full undercarriage for uneven wear, bearing play, hooked sprocket teeth, and track tension issues.
    How do I confirm this product fits the Kubota U25?
    Confirm fitment by checking your machine make, model, serial number, and existing track size or OEM part number. For rubber tracks, verify width, pitch, and link count. For undercarriage parts, compare the part number, bolt pattern, tooth count, and machine position. You can also use the TrackTECH Track Finder or call (850) 816-7898 before ordering.
