• Q: How to Remove the Left Camshaft on 2006 Jeep Liberty?

  A: Be sure the timing chain is not spun incorrectly, apart from the desired rotation, before removing the left camshaft to stop damage to the valves or pistons. Be sure to use Special Tool 8379 during the removal of the cam sprocket, timing chains or camshaft to prevent the ratchet on the hydraulic tensioner from stretching. The first step is to remove the cylinder head cover and place the engine at TDC for cylinder #1, so the camshaft sprocket V6 marks are facing at the 12 o'clock position. You should mark one link on the secondary timing chain on both the left and the right side so you can see when you install the V6 mark from the camshaft sprocket. Dont try to pry on the camshaft target wheel or it might get damaged. Don't remove the camshaft sprocket retaining bolt; simply loosen it to make sure the timing chain tensioners are tied down to stop the chain from extending. Slide Special Tool 8379 between the timing chain strands, then tap it to hold the chain tightly against the tensioner arm and guide. Hold the camshaft firmly with Special Tool 8428 and by hand rotate it towards the right to get to the middle position. Turn each bolt ½ times in the direction they are in to remove all their tension. Mark the rocker arms before you remove the camshaft and then remove the bearing caps and camshaft. For installing the camshafts, clean their journals with oil and install the left camshaft so that its sprocket dowel is near the upper 12 o'clock part, for convenience in fitting the bearing caps. Before fitting the caps onto the camshaft bearings, ensure that the arrows on every cap are all pointing toward the front of the engine. Initially, start by tightening the middle cap retaining bolts, moving to the ones adjacent and then torqueing each bolt with 11 Nm (100 inch lbs.) Line up the camshaft drive gear with the timing chain, using the V6 mark between the two previously lined up chain links. Keeping Special Tool 8428 inside the engine, turn the camshaft until the dowel on the sprocket lines up with the slot in the sprocket, then fit the sprocket. Maintain safe pressure on the camshaft shaft by wiping away excess oil from its bolt, apply a little torque with your hand and then get rid of the timing chain wedge. Use Special Tool 6958 combined with adapter pins 8346 to secure the cylinder head cover after giving the retaining bolt for the camshaft sprocket a tightening shock of 122 Nm (90 ft. lbs.).
