Re: EN-6625, it doesn't tell you when to do it because this isn't a 100% complete step by step set of instructions. It is installed during the steps that need to be done to remove the balancer.The instructions mention removing the EN-6625 crankshaft locking tool, but never mentions installing it. When is that done? Also, it mentions installing and removing the EN-6340 tool a couple of times. Why?
Re:EN-6340, the first time you install it it is to hold the cams timed while you have to belt off and are installing the new one. You remove them so you can spin the engine over, and you them back on to verify the timing.
