Fabco 675C-10166 or 675C10166 O-ring, identified by the AS-166 designation in its part name. It is a rubber sealing ring that sits in a groove and is compressed between two mating surfaces so oil or air stays inside the assembly.
When a ring like this is worn, it often shows as a flattened shape that no longer rebounds, ragged or chewed edges from being forced into a gap, or fine surface cracks. Leakage or pressure loss is usually what the operator notices first. A genuine Fabco part from Pro Gear and Transmission. Not sure this is the ring you need? Give us a call.
