Tips for Identifying Your Bobcat Final Drive Motor

If you have a Bobcat, it can be a challenge to correctly identify which model you need when it's time to replace your final drive. In this Shop Talk Blog post, we are going to cover how to differentiate between the most confusing models.  It's important to recognize the differences if you want to make sure you order the correct one for your machine!

Identifying Bobcat T140 / T180 / T190 Final Drive Motors

There are four types of final drive motors for these Bobcat machines (T140, T180, and T190) based on characteristics such as  how many hydraulic ports they have, how many sprocket bolts, and whether they are short-nose or regular final drive models. Let’s start with the five-port final drives.

Five Port Drive Bobcat T140 / T180 / T190 Final Drives

If your Bobcat final drive has 5 hydraulic ports, the 5th port will be located at the bottom of the drive on the flat cover plate that is held on by 24 bolts. There are two types of five port Bobcat final drives: short nose and regular nose.  Shown below is an easy way to determine which 5 port model that you have.

Note that the dimension shown on the regular model is 6.5" and the one for the short-nose model is 6.25" -- only a quarter of an inch of difference amounts to major problems if you order the wrong one.  Be sure to take these measurements very carefully.

Four Port Bobcat T140 / T180 / T190 Final Drives

There are two types of four port final drives for the T140 / T180 / T190 models. The difference between them is very simple: one type has 12 sprocket bolts and the other has 6 sprocket bolts, just like you see in the picture below.

When it comes to final drives and travel motors for these Bobcat models, there are two types:  long nose and short nose.  The best way to tell the difference is look at the distance from the top of the center mounting flange to the top of the sprocket flange. For a long nose, this distance will be around 7″, but for a short nose it will be about 5 1/2″.

You can also determine if you have a long nose or short nose final drive by measuring the depth of the sprocket, as shown below.  The sprocket depth for the long nose version is 6" and the depth for the short nose version is 4.5".
