    Frequently Asked Questions

    Common questions about your machine rubber tracks

    What rear idler fits the New Holland LT185B?

    This rear idler is listed for the New Holland LT185B and matches OEM Part #87535299. 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 New Holland LT185B?

    Matching drive sprocket options for the New Holland LT185B include New Holland LT185B Sprocket | Part #87460888. 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 New Holland LT185B?

    Matching bottom roller or track roller options for the New Holland LT185B include New Holland LT185B Track Roller | Part #87535297. 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 New Holland LT185B?

    Matching front idler options for the New Holland LT185B include New Holland LT185B Front Idler | Part #87535298. Front idlers guide the track and help maintain proper tension, so inspect the flange, bearing condition, and wear surface before installing new tracks.

    What rubber tracks pair with this rear idlers?

    Matching rubber track options connected to this New Holland LT185B undercarriage setup include New Holland LT185B Rubber Tracks | 450x86x55 (Part #450X86X55). 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 New Holland LT185B part?

    Yes. Sprockets, idlers, rollers, and rubber tracks wear together as a system. Before replacing this part for the New Holland LT185B, inspect the full undercarriage for uneven wear, bearing play, hooked sprocket teeth, and track tension issues.

    How do I confirm this product fits the New Holland LT185B?

    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.
