Coats Tire Changer Parts: 8183312 Bead Loosening Cylinder
The bead won't break, and the tire isn't going anywhere. When your bead loosener quits mid-job, the whole bay stops with it. The Coats 8183312 Bead Loosening Cylinder is the OEM assembly that gets you back to seating and stripping rubber without a workaround. It's the actual bead breaker cylinder Coats builds for the job, not a generic stand-in that fights your machine.
This cylinder fits most Coats brand rim-clamp tire changers and carries a 3/4-inch thread diameter on the rod. That thread size is the detail that matters. Some Coats models run a 1-inch thread diameter and need a different cylinder, so confirming your rod thread before ordering saves you a return. When you're sourcing Coats tire changer parts, matching the rod thread is the difference between a bolt-in swap and a part that sits on the shelf.
You already know what a bead loosener does. What you need is one that installs clean and holds up shift after shift. This OEM unit does both, and because it's the factory design, some installs let you reuse the air fittings off your old cylinder to cut the swap time down.

Installation & Setup
Before anything else, check your rod thread. If your machine runs a 1-inch thread, this isn't the right part and you'll want the correct cylinder for that spec. Two minutes with a thread gauge up front beats a return later.
Once the thread's confirmed, the swap is straightforward. Because this is the OEM design, your existing mounting points line up the way they should. Some applications let you carry over the air fittings from the old cylinder, which trims the install time. Others may need new fittings, so have both on hand before you start pulling the old unit.
Applications
If your Coats rim-clamp changer is the workhorse of the bay, a dead bead loosener means dead time. This OEM cylinder gets it back in rotation.
General service shops running seasonal tire swaps need a bead breaker that holds up to volume. The factory cylinder is spec'd for it.
When downtime on a Coats changer stalls your whole fleet schedule, an OEM replacement keeps the machine consistent shift to shift.
Bringing an older Coats rim-clamp changer back to service? Pairing the right cylinder with wear parts like the bead loosener pad restores factory performance.
This is a repair-and-restore part, so it belongs in any shop keeping a Coats machine alive. When you're already pulling a coats tire changer parts diagram to find the right components, it pays to check related wear items in the same pass. The 104024 upper bead loosener arm part, the 8183606 bead loosener shoe sock, and a fresh bead loosener pad 8183034 are common companions on a full bead-loosener refresh, and a large bead loosener setup often needs several of these replaced together.

Frequently Asked Questions
Will this bead loosening cylinder fit my Coats tire changer?
It fits most Coats brand rim-clamp tire changers, but the key detail is the rod thread. This cylinder has a 3/4-inch thread diameter. If your machine uses a 1-inch thread diameter, you'll need a different cylinder. Check your rod thread before ordering, and call us if you're not sure.
How do I know if I have a 3/4-inch or 1-inch thread?
Measure the thread diameter on your existing cylinder rod with a caliper or thread gauge. This part is built for the 3/4-inch thread. If you measure 1 inch, it's the wrong cylinder for your machine. When in doubt, give us your model and we'll help you confirm.
Is this a genuine OEM Coats part?
Yes. The 8183312 is a genuine OEM Coats bead breaker cylinder assembly, not an aftermarket copy. It's the factory design, so it lines up with your machine's existing mounting points and matches original performance.
Do I need to buy new air fittings with this cylinder?
Not always. Some installs let you reuse the air fittings from your original cylinder, which speeds up the swap. Others may require changing them. Have both options ready before you start, and call us if you want to confirm what your setup needs.
What is this cylinder made of?
It's built from high-grade steel for consistent performance during tire servicing. It's designed to hold up to repeated bead-breaking cycles shift after shift in a working bay.
What other parts might I need for a full bead loosener refresh?
Alongside the cylinder, shops often replace the bead loosener pad 8183034, the 104024 upper bead loosener arm part, and the 8183606 bead loosener shoe sock. If you're rebuilding an older machine, checking a coats tire changer parts diagram helps you catch every worn component in one pass.
Is this cylinder covered under warranty?
Tire changer accessories carry a 1-year parts warranty with no labor warranty. Note that wear items like bead loosener pads are excluded, since they're consumed in normal use. The cylinder assembly itself is covered against defects in materials and workmanship.
Can you help me find the right part if I'm not sure?
Yes. Call (855) 498-2147 with your Coats model and rod thread size, and we'll confirm the right cylinder for your machine plus any related coats tire changer parts you need. Sourcing the correct part the first time saves you a return.
