Camshaft Removal

[faviles]

So I am about to remove my two camshafts from my cylinder head and I wanted to know if it would be a good idea to take a picture of the way they were aligned before? Would I have to drop them in the same way as they were prior to removing them or would I be able to just drop them in and align them when setting the timing?

I just don't want to remove them and stay stuck trying to figure out how to put them back in later on.

Thanks!

Cams have a three hole dowel pin in them for the cam gears to align to. On the back plate of the rear timing plate cover has two notches to align the timing marks on the cam gears. You install the cam gears on the cam using the center dowel pin hole.

Stock cams are non interferrance meaning the valve will never touch which means it doesn't matter which way there turned when going back in.

Just make sure all the shims on the buckets stay in the same place.

Start Here^ make sure that first of tightening the bearing caps is in several passes to "walk" the cam down. Notice the orientation/clocking of the cams, its important to the tightening sequence

It sure is a good idea. Turn the crank bolt so the match marks are straight up and inline. Then you will know it is wrong before starting another thread on SM saying it doesn't run right.

When you say "stripped" You meant "rounded off the bolt head". Is that correct? If so. You should look at some tool upgrades. Having the right tool for the job makes everything go smoother.

Imagine walking up to that bolt with your 3/8" air impact or good cordless and 14mm impact swivel and hit the trigger. You would remove both cam gear bolts with out any problems. It is nice to Air remove fasteners and use hand tools for reassembly.
