We'll start with the Bobcat T200 / T250 / T300 / T320 / 864 track drive motors. First of all, there are two basic types: long nose and short nose--and two ways to figure out which one you need.
The easiest way to determine which one you need is to just measure the depth of the sprocket: the depth for the long nose version is 6 inches and the depth for the short nose version is 4.5 inches.

There's a second way, BUT IT DOESN'T WORK FOR THE BOBCAT T-650.
Look at the distance from the top of the sprocket flange to the top of the center mounting flange. As you can see below, the distance for a short nose is 5.5 inches and for a long nose is 7 inches.

If you have a Bobcat T140 / T180 / T190 final drive, you need more than measurements: start with how many hydraulic ports there are on the track motor. To determine if your drive motor has a 5th port, look at the bottom of the drive on the flat cover plate that is held on by 24 bolts. The picture below shows you where to look.

Once know you have a four port final drive, the next step is too look at how many sprocket bolts there are One type of Bobcat final drive will have 12 sprocket bolts and the other will have 6 sprocket bolts. The picture below shows the difference.
When you order your replacement drive, you will need to indicate how many sprocket bolt holes that your current track drive has.
