I noted two oversights while watching this video and it probably answers Volkswatson's question of a year ago. It virtually applies to any occasion when you are setting up timing marks. FIRSTLY when checking the piston is coming up to top dead centre (with a long screw driver sitting on top of the piston, through the plug hole) you have to ensure the piston is actually on the compression stroke!!! Block the spark plug hole on No 1 cylinder with your finger and as you turn the pulley to bring the piston up- it should force/expel air from around your finger! If it doesn't, you are on the exhaust stroke and even though the piston is at top dead centre, the timing will be 180 degrees out! This is a common mistake when the belt is being replaced or while reassembling a striped down engine. SECONDLY- There is a certain amount of slack or lag between the lower crankshaft pulley moving and then the upper cam shaft pulley being moved by the belt. Peter sort of alluded to it while pointing at the bottom pulley at (see 22.10- 20). You can see the mark is not really in the right position and here's why- Assuming the belt is in place and the spark plugs have been removed, Fit a socket and lever bar on the crankshaft pulley's centre bolt (again 22.10). Now rotate the pulley a small way around by turning the bolt as if you were tightening it. This just loads up the belt and the pulleys under a certain amount of tension in the forward direction. Now, slowly apply reverse rotation to the crank pulley while watching the position of the cam shaft pulley as you do so. You will feel or observe that you can turn the crank pulley backwards a small amount, before the cam pulley actually starts to move. Once you have moved the crank backwards, try moving it slowly forwards again and again you will notice a slight lag between the two pulleys moving. This can be enough to put the timing marks out of alignment by one tooth on the belt. This is particularly common when you are refitting a belt! I often see beginners turn the crank pulley up to the mark too quickly and overshoot the mark as it were. The fatal mistake is then made to just wind the crank pulley backwards slightly, to get the marks to line up - there goes the slack in the system. If you have to back the crank pulley off, to then bring it forward again to the correct position, make sure you take it back far enough so that you remove any of the slack as you come up to the marks. Never turn the crank backwards to bring the marks into alignment! Always turn forward and ensure the tension in the system is being applied to all the components as you slowly bring the crank pulley forward to the desired point. It is easier to pause before the marks line up and then just gently tap on the lever bar with the butt of your hand to bring the bottom pulley into alignment with the mark. Then you can check to see if the top pulley is actually where it should be!!! I sincerely hope this helps cos they are easy traps for beginners and should have been highlighted.
