Loosen the cable on the negative terminal of the battery, right, then remove the vibration damper and crankcase cover. Remove all of the spark plugs from the engine. Loosely replace the crankshaft pulley bolt with several thickness of washer or spacer and rotate the crankshaft in anticlockwise direction to align the timing mark on crank shaft and cam shaft so that the
Camshaft sprocket and chain will also be properly aligned. Head the camshaft sprocket mounting bolts, held the camshaft sprocket from the camshaft and get rid of the sprocket and chain. If required, employ the special tool of puller to remove the crankshaft sprocket. Fits the crankshaft sprocket on the crankshaft in the same way in which it was removed by using one of the bolts and washers from the puller. Place the timing chain above the camshaft sprocket and provide some tension by having some part of the chain hang over the crankshaft sprocket. When the timing marks perfectly align, then place the chain over the crankshaft sprocket and then slide the camshaft sprocket over and tighten the bolts. After that check the alignment of the timing marks both on camshaft and crank shaft sprockets where camshaft sprocket mark should be made at 6 'o' clock and crank sprocket mark should be made at 12 'o' clock and a line passing through the center of both sprockets must pass through both timing marks. If misaligned, position the camshaft sprocket as it is indicated that upon proper alignment, the engine is set in a manner whereby the number six piston is at TDC on the compression stroke. Last but not the least, pour some drops of engine oil on the chain and fit all the other parts starting from the one, which was removed last.
