This is the aftermarket Bobcat T870 drive sprocket. This durable sprocket is made to original specifications with eight bolt holes and seventeen drive teeth exactly as your original. This sprocket is also known to be an option for the T770 but you must verify your number of bolt holes. We also stock the idlers and bottom rollers as well as the rubber track for the Bobcat T 870 for complete undercarriage maintenance. Rely on Pentom Supply to have what you need at an affordable price when you need it most. Save more by purchasing tracks and sprockets together. We offer a 5% discount for rubber track and sprocket combos, and changing the sprockets at the same time as the track will extend the lifespan of the track.
Be aware that some earlier model T870 track loaders come with the six bolt sprocket option known as part number 7107787 or 7165109
Once you remove your sprocket you can place it face down on a flat surface and measure from the surface to the edge of the mounting hole (as pictured) and it should be right at 6 1/4 inches.
