September / October 2015 16 With one of the banks completed, you will rotate your crankshaft 360 degrees and install the other bank in the same fashion. At this point you should have a full assembled long block that needs the final camshaft timing completed. Timing the cams is a lot easier process on these engines that older air-cooled engines that required dial indicators and degree wheels. The factory tools will help align everything properly and are fairly straight forward. Again, it does not matter what side you start on, but you will need your cylinder 1 or 4 on TDC compression stroke. The factory tool will insert into the notch on the end of the exhaust cam. Note, this notch is not centered, but rather offset, so the tool will only fit with the cam pointing one direction. If the cam is 180 degrees out, then you will need to rotate your crankshaft until the cam is pointed in the proper direction. Install your factory tool (5 chain motor) onto the engine, and loosen the 4 bolts on the front sprocket of the exhaust cam. This will allow the cams to rotate in relationship to the crankshaft. Note: The 3 chain engines will use a different (and simpler tool) than the 5 chain motors. Since they are much easier to time, I won't go into detail here on them. The top post of the tool should insert into the hole in the back of the intake camshaft cover. If it does not, then use the tool to rotate the camshafts in the proper direction until it falls into place (the tool will catch the notch on the exhaust cam and allow everything to rotate using the tool). Once that occurs, you can lock down the 4 bolts on the front of the exhaust cam sprocket, and that bank will be correctly timed. Turn the crankshaft over to the other bank and time exactly the same. Always rotate the crank and check alignment numerous times throughout the process to ensure timing is
