2001 400ex timing problem.
You've got the right steps down. Line the indicator mark up with the notch just in front of the T, put the cam sprocket in the with the side marked OUT to the outside. Line up the the two marks on the cam sprocket with the top of the cylinder head and make sure the third mark on the cam sprocket is on the top. Then slide the cam into place making sure the lobes are pointed down, put the bearing on the ends and push the cam sprocket onto the cam and put one of the cam bolts in. At this point check to make sure the indicator marked T is still lined up and double check the marks on the cam sprocket, if it is still lined up correctly rotate the engine so that the other bolt hole on the cam sprocket is exposed and install the second bolt. A couple of things to be careful of - 1. Make sure the cam chain tensioner is in place and tightened to normal when you are adjusting the cam sprocket/timing, otherwise it will be off when you do install the tensioner. 2. Make sure you dont drop the cam bearings or alignment pins that sit just outside the bearings into the engine, it will save you alot of headache, believe me.
