This rear window hinge is a bodywork component that supports the cab rear window and controls its opening arc. It is mounted on the cab frame and engages with the window panel to keep the glass aligned during opening and closing. A worn or loose hinge causes the window to sag, leading to misalignment, increased seal wear, and potential glass stress. AGCO manufactures this hinge to match the original pivot geometry and mounting-hole pattern of the cab assembly, so no drilling or adaptation is required during replacement. On reinstall, use the original hardware and torque the mounting bolts to the cab-frame specification.
