    Frequently Asked Questions

    Common questions about your machine rubber tracks

    What front idler fits the Cat 304CR?

    This front idler is listed for the Cat 304CR and matches OEM Part #241-5973. Before ordering, compare your machine make, model, serial number, and existing part number to confirm the correct undercarriage position and fitment.

    What sprocket fits the Cat 304CR?

    Matching drive sprocket options for the Cat 304CR include CAT 304CR Sprocket | Part #158-4795. When installing new rubber tracks, inspect sprockets for hooked, sharp, or uneven teeth because worn sprockets can shorten track life and damage the drive lugs.

    What bottom rollers fit the Cat 304CR?

    Matching bottom roller or track roller options for the Cat 304CR include CAT 304CR Track Roller | Part #340-8957. Replacing worn rollers before installing new rubber tracks helps keep the undercarriage aligned and reduces uneven wear across the track carcass.

    What top roller fits the Cat 304CR?

    Matching top roller options for the Cat 304CR include CAT 304CR Carrier Roller | Part #277-8576. 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 front idlers?

    Matching rubber track options connected to this Cat 304CR undercarriage setup include CAT 304CR Rubber Tracks | 400x72.5Wx72 (Part #400X72.5WX72). 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 Cat 304CR part?

    Yes. Sprockets, idlers, rollers, and rubber tracks wear together as a system. Before replacing this part for the Cat 304CR, inspect the full undercarriage for uneven wear, bearing play, hooked sprocket teeth, and track tension issues.

    How do I confirm this product fits the Cat 304CR?

    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.
