Replacement Bobcat® T190 Sprockets
This is the optional aftermarket replacement drive sprocket for the Bobcat® T140, T180, and T190 track loaders. This is the newer deep dish (wide) sprocket. If you have changed to the new drive motor you will need this deeper sprocket. This sprocket normally fits serial number 231611001 and above. You should always install your sprockets to the correct torque specs without over tightening the bolts resulting in damage to the sprocket.
- 15 Teeth
- 6 Bolt Holes
- Inside Diameter: 3 3/4 Inches
- Outside Diameter: 16 1/2 Inches
- Depth: 5 3/4 Inches
The cast number that is usually stamped into the sprocket is 6736305, but that is just the casting number for the original part number 6736306 which fits the deeper drive motor known as part number 6686384. It also fits any machine with the updated drive motor or current production. This sprocket is also commonly known as Bobcat® part number: 7165111, 7165110.
If you were to remove the sprocket and lay it face down on the ground and measure through the mounting hole to the surface you would get 5 3/4 inches in depth (or width) as seen in the picture. This is by far the more common option for the current model Bobcat® loaders that still have six bolts.
We carry the full undercarriage for the Bobcat® track loader series. Experts suggest changing your sprockets and rubber tracks at the same time for maximum lifespan. Never allow your sprockets to wear to a point or a curve. That will cause the rubber track links to rip out prematurely.
This is the current generation 6B/15T sprocket but a previous generation version exists under part 6726052 so please verify tooth count and bolt count as well as depth. We use the OEM numbers for reference if you know the sprocket from your parts manual.

Reliable Sprocket Hardness
Our track loader sprockets start out with high quality steel. Since the focus of the hardening is localized to the drive teeth we use a type of spin induction heat treatment followed by an immediate quenching process which rapidly hardens the tooth several millimeters deeper than our competitors sprockets. Our sprockets are hardened within millimeters of the OEM sprocket providing you the best value for your replacement parts.
