The Woodruff key seats into a matching semicircular keyway in the shaft, with the flat edge engaging a longitudinal slot in the mating gear, hub, or pulley hub. This design locks the rotating component to the shaft, preventing independent rotation while also acting as a mechanical fail-safe that protects costlier components from damage under overload conditions. It is a direct aftermarket replacement for the Caterpillar OEM part number 1B8745 \/ 1B-8745.\u003c\/p\u003e\u003ch4\u003eCompatible Models\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eCaterpillar (Cat):\u003c\/strong\u003e Verify fitment against your machine serial number and parts manual.
