I went to replace the timing chain today. The old one came off no problem (holy crap, tons of slack!!!) and I neglected to look at how the sprockets came off (which direction forward). I've got a new Cloyes kit to go on which comes with sprockets and the chain and figured out which way the cam sprocket goes on pretty easy due to the eccentric for the fuel pump but the crank sprocket confuses me a little more. The concave part of the sprocket faces towards the rear of the truck and the flat face towards the front correct?

And really Ford? Nylon teeth on the cam sprocket? Really?

 

The timing mark faces out.
Also, if you have the two piece fuel pump eccentric like I have, be sure the outer shell still spins after you torque the bolt down.
After the crank sprocket is installed, don't forget the oil slinger.

 

The oil slinger is that disc that slips over the crank snout after the sprocket is on correct?

One more question.

The locating pin for the cam sprocket. The new timing kit didn't come with one so I knocked it out of the old sprocket and inserted it into the new one. It seems to slide much easier in the new one than the old. Im not worried about it backing out or anything because I see that the cam eccentric has a tab that goes into the other side of the pins hole and would keep it from backing out of the cam completely. It does however make me uneasy putting the sprocket onto the cam itself cause I can't tell for sure if its seated correctly. Am I just worrying for nothing? When the kit is installed I can't hardly get any movement out of the sprocket rotating side to side but the chain is also in much better shape than the old so its hard to tell.

 

Don't worry about the pin, just be sure it's not too long and crushes the tab on the eccentric. If you find it is too long (you're using an old pin, so it should be okay) just grind it down to fit.
And yes, that's the oil slinger.

 

Lol I figured out my own question just sitting here. I just inserted the pin into the cam first, then slipped the sprocket over it.. So simple... I was trying to put the sprocket on with the pin already in it... Duh...

One more question though. Below is a picture of how i've got everything installed (aside from the eccentric and oil slinger) Does this look correct? I've got the keyways vertical how it looks like in the Chiltons manual I have. There is a timing mark on the cam sprocket pointing straight up though... Im certain its on TDC compression on #1 and I didn't move anything taking the old chain off so its gotta be fine. Just want an opinion. As I said in another post this cam-in-block V8 stuff is all new to me. Im here to learn!

 

I think your cam is 180 degrees out. Look closely at Mike's picture. See how the timing mark on the cam gear and crank gear are directly across from each other? Mike's cam gear is installed correctly - Your's is NOT.

 

Yup, it's 180 degrees out. Both sprockets will have timing marks on them. Both of these marks face "out" so you can see them. They are aligned so they are next to each other. The crank mark is at 12:00 O'clock. The camshaft gear timing mark is at 6:00 O'clock.
Like Canus said, look at the picture I posted, you can see the marks. Just a note, in the picture the crank gear is set up so I can advance or retard the cam. That's why there are multiple keyways.

 

I must be at tdc on the exhaust stroke then. Are these motors interference? I wont hurt anything turning the cam alone.

Edit: im confusing myself. Its not on the exhaust stroke....

 

Acutally i should be able to just rotate the crank 360 and the marks should line up then if its on correctly right?

 

Turns out everythingis fine. Rotated the crank 360 and the marks line up as they should. Ive been overthinking things.

 

Jetrinka, they have to be lined up with the #1 cyl at tdc and valves closed(combustion stoke) not to be captain obvious but you made it sound like you just turned the crank until it lined up...

 

Nahi left the chain on like it was in the pic i posted above and put the crank bolt back in so i had something to rotate the engine with. Spun the engine aroind once (360 degrees on the crank) which brought the timing marks into alignment where they should be. I never rotated either the crank or cam independently of each other. I must just have made a mistake when finding tdc compression before removing the timing cover. Does this make better sense or am i still missing something?

 

That will be okay, you now have #1 cylinder on compression. The way you had it originally you had #1 on the overlap stroke. For that to work you would have had to pull the distributor and rotate it 180 degrees.

 

Luckily the distributor is already out. Lol. Or i should have said unluckily... Would havebeenmuch easier to find the correct timing orientation by just looking at the direction of the rotor. Oh well. Live and learn.

I really appreciate everyones help and patience. This is sure a friendlier online environment than alot of others i have experienced!

 

The new timing kit didn't come with one so I knocked it out of the old sprocket and inserted it into the new one.
