Ford Tappet Compressor T89P-6500-A Placement Diagram - DOHC Valve Shim Service

This is a single-page service illustration showing the placement of a valve tappet compressor tool during a valve adjustment procedure on a dual overhead cam (DOHC) engine. The line drawing depicts a technician's hand inserting the Tappet Compressor, Ford special service tool number T89P-6500-A, between the camshafts of the cylinder head to depress a valve tappet (lifter bucket). A callout instructs the technician to "NOTE POSITION OF CAM LOBES," indicating that the camshaft lobe orientation must be observed before compressing the tappet — typically so the lobe is not pressing on the tappet being serviced. The figure reference number A12910-B appears in the lower right corner. This illustration is part of a multi-page valve clearance adjustment set (companion pages include valve clearance check, shim removal with compressed air, and tappet holder placement), and this page specifically teaches where and how the tappet compressor tool is positioned on the cam carrier so the valve adjusting shims can be removed and replaced. No torque values, part numbers other than the tool number, or year/model applicability statements appear on this page.
