<b><i>A MUST HAVE TOOL FOR FORD 4.6L 5.4L 3V 6.8L 8V ENGINE AND TIME SAVING FOR YOU</i></b> <p></p> <b><i>Package Included :</i></b> 1pc Valve Spring Compressor tool & 1pc Cam Phaser Locking Tool &1pc Crankshaft Positioning Tool &1pc Crankshaft Pulley Bolt. <p></p> <b><i>Valve Spring Compressor tool:</i></b> Allows you to replace rocker arms, lash adjusters, and other valve components without removing the camshaft. Please make sure the arm that pushes on the spring retainer has a clear path downward. If this arm gets hung up on cast-in features of the head while attempting to compress the valve spring, undue stress may be put on the tool. <p></p> <b><i>Crankshaft Positioning tool: </i></b> position the crankshaft at top dead center for correct timing chain installation. DO NOT rotate the crankshaft and/or camshaft(s) when removing the timing chain(s) and installing the cylinder heads. Because this is not a free-wheeling engine, if it has "jumped time" there will be damage to the valves and/or pistons, which will require the removal of the cylinder heads. <p></p> <b><i>Cam Phaser Holding/Locking Tool: </i></b> Installed to torque the camshaft phaser boltto specifications according to the vehicle servicemanual and make your job much easier. To prevent equipment damage, use only hand tools for installation and removal of the camshaft phaser sprocket assembly. <p></p> <b><i>Timing Chain Locking Tool: </i></b> Makes easily camshaft or cam phaser changes on your vehicle without losing chain tension and removing the timing cover. Do not remove the tool at any time during service. If the tool is removed, the timing chain will move out of time and the front cover will have to be removed to re-time the engine. <p></p> <b><i>Crankshaft Pulley Bolt: </i></b> Same as Ford F5RZ-6A340-B, ensure the pulley and timing gears do not slip.
