  Q: How do Cam Gear and Variable Timing Solenoid relate to the procedure for using the camshaft locking tool 999 5452 and fabricating a home-made alternative on Volvo S40?

  A:

  For this procedure, the Volvo camshaft locking tool 999 5452 is required to prevent camshafts turning while the sprockets are removed and details for making a home-made alternative are provided. Remove the timing belt, then the air cleaner assembly and intake ducts to get to the left-hand end of the two camshafts. Disconnect brake servo vacuum pipe and EVAP pipe to the intake manifold, and then take off the screws to remove the intake manifold, plug the lower openings to avoid pollution. Unhook the EVAP canister valve, undo the fuel pipe bracket bolt, and unhook the oxygen sensor wiring plug. Using a screwdriver, remove the plastic blanking plug on the end of the camshafts, then undo the screws and remove the rotors, being willing for oil spillage. Make sure the slots in ends of camshafts are parallel to the join between upper and lower cylinder head sections before locking them in position. Get the volvo or make your own way of locking the camshafts, check that the crankshaft sprocket timing marks match and lock the locking tool in place. If both camshaft sprockets are to be removed, mark the sprockets for identification. For a sprocket with a variable valve timing unit, use a Torx 55 key to remove the plug and central retaining screw and withdraw the sprocket. For a non-variable valve timing sprocket, remove the three bolts and the sprocket, holding it back with a suitable tool. Carefully remove the seal, without damaging the sealing face of the shaft, clean the seal seat, and lubricate the new oil seal, and fit it over the shaft. Temporarily refit timing belt upper cover, check the position of the crankshaft, and turn it clockwise a little. Take out the starter motor, unscrew the blanking plug and insert the Volvo tool. Rotate the crankshaft in the anti-clockwise direction until it stops against the tool, making sure that the marking on the crankshaft sprocket lines up with the marking on the oil pump housing. Press the VVT unit/camshaft sprocket onto the camshaft and re-fit the central retaining screw without tightening it. Refit the camshaft sprocket with the timing marks aligned, tighten the retaining bolts just enough to allow the sprockets to turn and check the crankshaft pulley marks. Remove timing belt upper cover and install new timing belt and tighten VVT unit central retaining screw and non-VVT sprocket bolts to the specified torque. Refit centre plug to VVT unit and check timing belt tensioner arm position and adjust if needed. Finally remove the camshaft locking tools and crankshaft stop tool and turn the crankshaft clockwise two complete revolutions and ensure that all the timing marks can be realigned, and the tensioner pointer is aligned with the central notch if fitted. The rest of the process is to reverse the removal process.
