Im trying to track down some sprockets for a Rayco T275 forestry mulcher. Some general specs are 22 hole mounting, 23 teeth . 16mm bolt holes, 25" OD and 15-3/4" ID.. This machine has a variety of undercarriage parts intended for multiple manufacturers machines. Why is undercarriage such a secret? I cannot find any manuals, catalogs or cross refference material online anywhere.
ITP might be a good place to start. Industrial Tractor Parts, they are more east of the Mississippi but ship all over. Used to use them for years to order UC for our dozers, etc. https://industrialtractorparts.com/index.html
Any help in here HeavyEquipmentForums
That thread helps for everything but the sprockets. Im suspecting these may be JD 590D or Hitachi Ex150 sprockets but without inspecting them or getting measurements its just a guess. All of the other undercarriage parts can be crossed to JD Dozer and Excavator parts.
