So we will start this process with making sure the crankshaft is in position with the crank key at 5 o’clock (timing mark at 12 o’clock), and we are installing the cams. The intake and exhaust cams are specific to location so make sure to check part numbers before install.
You will install the driver side cams first. Make sure to install them with the notches on the cams in this location. This will put the cams in a “neutral” location so you’re not pressing open a bunch of valves when you torque the cams down, it also puts them in the correct location for the phasers to install.
Next will be putting the secondary chains on the phaser. The exhaust phaser is the one with the large sprocket for the primary chain. Make sure to line the secondary chain up as shown. The double link on the intake phaser and the single link on the exhaust. If you orient them like the picture, they will be clocked correctly to go on the cams.
Now we will install the phasers on the cams. This can be kind of tricky because you have to compress the tensioner to get the chains on. If you just barely start the phaser on the cam, you can press the tensioner down and slip the chains over it. It’s easier to have a helper for this.
To get the phaser all the way installed you may have to rotate the cams slightly one way or the other to make sure they lock in to the alignment dowel in the phaser. When they are all the way installed the chains will be lined up as such:
One thing to note, on the tensioner, there is a “ramp” that will help install the chain. Make sure that is facing front. If it’s facing rearward, the chain will not run centered on the plastic guide and it will get chewed up.
After the phasers are installed completely and bolted down, install the primary chain guide.
