Bandit Drive Coupler FAQ & Guide
Bandit Industries builds some of the toughest wood and waste processing equipment in the world – from hand-fed brush chippers and stump grinders to whole-tree chippers, horizontal grinders and forestry mowers. These machines live in brutal environments: constant shock loads, heavy trunks, contaminated material and long hours. In the middle of all that work is a small but critical component – the Bandit OEM drive coupler that connects engines and motors to drums, cutters and hydraulic systems.
At Stark Industrial Products, our role is simple: when a Bandit machine is down because of a failed coupler, we help you put it back to work with the correct genuine OEM coupler as quickly and cleanly as possible. This page explains where couplers fit into Bandit equipment, how to identify the right part, and how our team supports you when every hour of downtime costs money.
Where Bandit Machines Use Drive Couplers
Bandit machines are built for tree care, land clearing, biomass, recycling and waste reduction. Many of these units rely on heavy-duty drive couplers between the engine or power unit and key components such as cutter drums, feed systems or hydraulic pumps. On hand-fed and whole-tree chippers, the coupler has to handle repeated shock loads as material slams into the drum. On horizontal grinders and “The Beast®” recyclers, the coupler manages high continuous torque, debris and vibration. When a coupler fails, the machine is effectively dead – which is why choosing and installing the correct OEM coupler is mission-critical.
Because Bandit offers a wide range of models and configurations, there is no “one-size-fits-all” coupler. Bore sizes, keyways, bolt patterns, elastomer elements and torque ratings all vary by model. Stark Industrial focuses on stocking and sourcing genuine Bandit OEM drive couplers that match the specific engineering requirements of each machine rather than guessing with generic parts.
How to Identify Your Bandit Drive Coupler
The fastest way to identify the proper Bandit coupler is by OEM part number from the parts book, service manual or Bandit nameplate. If you have documentation handy, include the model number, serial number and any coupler or hub part numbers when you reach out to us. If paperwork is missing – which is common in the field – you can still identify the correct coupler with a few simple checks.
Start by inspecting the existing coupler or hubs for stamped or cast numbers. Then take basic measurements: outside diameter, overall thickness, bolt pattern, bore size and keyway dimensions. Note whether the coupler is a solid hub design, a flexible element system, or part of a larger clutch assembly. Photos are extremely helpful: a clear picture of the coupler and the Bandit machine’s data plate lets our team cross-reference your setup against OEM information and our internal records.

Bandit Drive Coupler FAQ
What are the signs a Bandit drive coupler is failing?
Common warning signs include unusual vibration, noise at startup, rubber or element material shedding, visible cracking or tearing, and changes in chipper or grinder performance. In severe cases the machine may fail to transmit power at all. If you see these symptoms, shut down, inspect the coupler and plan a replacement before it fails completely.
Can I upgrade or change coupler styles on my Bandit machine?
Because Bandit designs its machines around specific OEM coupler styles and ratings, we recommend staying with the original specification unless an engineered OEM-approved alternative is documented. Contact Stark Industrial if you’re considering a change so we can review the application with you and make sure it stays within Bandit’s design intent.
How quickly can Stark ship a Bandit OEM coupler?
For part numbers we keep in stock, orders placed before our cutoff time typically ship the same business day from our Texas warehouse. For other OEM Bandit couplers, we’ll give you an honest lead time and help you choose the best shipping option based on how urgently the machine is needed on the job.
