Rear Camshaft Locking Tool

The IPD Rear Camshaft Locking Tool (part number 120980, OE reference 9995452) is engineered to transform complex engine maintenance on Volvo vehicles into a manageable DIY task. It is indispensable for procedures like timing belt replacement and the often-tricky job of replacing front camshaft and crankshaft oil seals on all Volvo whiteblock engines. The tool's design directly addresses the challenges posed by newer engines featuring CVVT (constant variable valve timing), ensuring the camshafts remain securely in place during timing belt removal. This tool distinguishes itself from older camshaft gear locking tools by its rear-mounted application. Instead of locking the cams via the front gears, this tool engages the camshafts directly at the back of the cylinder head, holding them firmly together. This precise engagement is crucial for preventing any "jumping time" or unintended movement of the camshafts, particularly when accessing and replacing front oil seals. Its use makes the process of replacing these seals a trouble-free operation. A critical fitment note is that this camshaft locking tool is not compatible with the 2.4i engine. When installing the tool, pay close attention to the offset keying on both the tool and the camshafts. The tool's key should align with the slot on the end of the camshaft. Ensure the bolt threads in smoothly without resistance, and that the offset direction on the tool matches the slot on the cam. Incorrect alignment could lead to shearing the cast key, so careful installation is advised. The product comes with a one-year parts warranty.
