  Q: How to remove and install the Timing Cover and Timing Cover Gasket on Volvo 780?

  A:

  To remove and install the 2.8L 6-cylinder engine cover and seal, disconnect the negative battery cable and remove the air cleaner and valve covers. Loosen the fan shroud and remove the fan and then the fan shroud itself. Loosen the alternator, air pump, power steering pump and air conditioning compressor, if equipped, and remove their drive belts. Block the Flywheel from turning, and remove the crankshaft pulley nut (36mm) and the pulley (without dropping the pulley key into the crankcase). Next, take out the power steering pump and set it to the side, then the pump bracket. Remove the 11mm hex retaining bolts for the timing chain cover, tap and remove the timing chain cover. Clean gasket contact surfaces, install the upper gasket on the cover and the lower gasket on the block and install the cover and tighten to 7-11 ft. lbs. (10-15 Nm). tightening the gaskets flush with the valve cover, fit a new Crankshaft Seal, block the flywheel, fit the pulley and key, tighten 36mm nut to 118-132ft.lbs.(160-180Nm) Reinstall power steering pump, pump bracket, alternator, air pump, air conditioning compressor, then fan and shroud, and finally, accessory drive belts. Finally, reconnect the negative battery cable, start the engine and see if there are any leaks. For seal replacement only, follow similar initial steps to disconnect the battery and remove components and use a suitable puller to remove the old seal with care not to damage the timing chain cover contact surface. Fill the space between the lips on the seal with grease, install the new seal with the correct tool, and finish reinstalling the components as was previously described, being sure to check for leaks once the engine is started.
