Coats OEM 8181990 Spider Casting Assembly For Tire Changer

Coats 8181990 Spider Casting Assembly - OEM Turn-Table Mounting Part

When the turn-table on your Coats tire changer starts showing slop or wear, a loose or degraded mounting assembly is often the culprit. The Coats 8181990 Spider Casting Assembly is the direct OEM replacement that restores the tight, stable clamping your machine needs. It mounts on the Clamping Cylinder and brings back the precision your machine had when it first came off the floor.

This is a genuine Coats part, made in the USA from cast metal. It's a fit-and-forget fix for shops running RC, 50X, 70X, and GTS series changers, as well as the 5030-5070 and 6050-6065 series. That covers a wide range of older Coats iron that's still pulling daily duty in shops across the country. No guesswork on fitment, no machining required. You get the same geometry and material spec as the original, so it drops in cleanly and your machine is back in rotation without extended downtime.

Aftermarket castings can introduce clearance issues that show up mid-job. With an OEM part, you're not troubleshooting a fitment mismatch on a busy Tuesday. The 8181990 is also referenced under part numbers BW-1219-90 and 181990, so if you're cross-checking your parts manual, it'll match. GSG stocks OEM Coats replacement parts so you're not waiting weeks for a single casting to come in. One unit per order.
