Bring the timing marks on the sprockets as close together as it's possible, remove the Timing Chain dampener's bolt and bolt and unbolt the Timing Chain dampener. Next, the camshaft sprocket bolt, then camshaft sprocket and timing.concurrent retval; if the sprocket will not pose, it may be pried off with a light tap on the lower edge with a plastic mallet. When required, discard the crank shaft sprocket and the balance shaft drive gear to have easy access to camshaft thrust plate, including its bolts. Inspect all components for wear or damage. If the pistons have been moved, then rotate the Crankshaft to bring the number one Piston to the top dead center, and align the camshaft so that the timing mark is rendered straight down at that point with the sprocket temporarily fit. A balance shaft driven gear may be required to install, in such a case prevent the balance shaft from rotating when tight balance shaft driven gear bolt to 22 n.m (16 lb ft) plus an additional 70 degrees using the torque angle meter (J 45059). The camshaft thrust plate and bolts must be installed, which should be tightened to the value of 15 n.m (11 lb ft) and followed by the balance drive gear of the shaft. On balance shaft drive gear and balance shaft driven gear, put balance shaft timing marks in line, after that to install the Crankshaft sprocket and the Timing Chain and sprocket and put the timing marks in the line as close as possible. Install camshaft sprocket bolt, and tighten to 100 n.m (74 lb ft) and additional 90 degrees with the torque angle meter (J 45059), and then install the Timing Chain dampener and tighten its bolt to 22 n.m (16 lb ft).
