Caterpillar 8T-7693 Ring Gear Assembly For Caterpillar 8T-7693

< p>CAT 8T-7693 wear ring (ring guide) for hydraulic cylinder assemblies used on Caterpillar machines, including models 769C, 769D, 768C, 770, 770G, and 771C. This replacement part is molded from plastic and provides a precise, low-friction bearing surface that guides the piston within the bore and helps minimize side loading during operation. The wear ring’s outer diameter is 184.20 mm, which is a key fitment specification to ensure correct seating and concentricity in compatible cylinders. As a dedicated 8T-7693 component, it functions as a critical cylinder-assembly wear element that supports steady piston travel, reduces wear on bore surfaces, and contributes to reliable hydraulic performance on applicable Cat equipment. When servicing hydraulic cylinders that use wear rings, referencing the 8T-7693 part ensures you select the correct plastic guide ring with the proper outer diameter for compatible Caterpillar models.
