To do this, to carry out the cylinder head cover and the timing chain cover removal, turn the
Crankshaft with the crankshaft pulley to the right TDC position for Nos 1 and 4 pistons and align the marks on the camshaft sprockets. Pull out the crankshaft pulley after duly positioning the camshafts. Press down the tensioner lever to retract the tensioner's plunger into its body ensuring that the holes are in line and use a metal bar pin that is passed through the holes to ensure that the two parts are held firmly in place. Loosen two retaining bolts to decrease the tensioner but keep the rod inserted and then, neutralize the upper pivot point for the chain tensioner guide and then, take it off. Two mounting bolts are undone to remove the chain front guide, then the timing chain is detached from the crankshaft sprocket and pulled out from the engine. Loosen the camshaft sprocket retaining bolts when the camshaft was held using a spanner on the other end, followed by the removal of the bolt and taking off of the sprocket. To get the crankshaft sprocket out, one has to pull the combined oil pump and chain sprocket away. Check the teeth of the camshaft and crankshaft sprockets for wear or signs of damage and replace them both simultaneously to a set. Inspect the timing chain links to make sure they are in good shape as excessive side play signifies that they ought to be renewed. If the engine has a high mileage, then therefore, it is appropriate to replicate the timing chain, or also if it developed some noise. Look at the chain guides and see whether the chain tensioner is worn out; the plunger should easily run in and out. For refitting lighten the crankshaft until the TDC while reconnect the sprockets and camshafts and tighten the bolts. Positive the camshafts are still in the TDC position, move the chain to the best position to align it with the crankshaft sprocket and connect it with the camshaft sprockets. Insert the chain front fixed guide and the chain rear tensioner guide followed by fixing the chain tensioner using the tensioner bolts and acknowledged that the plunger is forced out against the guide. Make sure that all the timing marks coincide with the chain links, install the crankshaft pul, rotate the engine half a turn clockwise, align the timing marks, and rotate the engine another half a turn. Last but not the least, replace the timing chain cover.
