on your last vid i noticed your belt is tilted in the at rest contition could someone have not shimmed or whatever your cams making them be closer to the block and causing the **** to be slanted and walk around like it was doing? Grab your straight edge and see if you can get a reading on how straight your gears are on the horzintal, and i would throw a level on there to see if maybe something isnt tilted on one or both gears. 9-10 times i see **** like that at work its a pulley or gear problem being misaligned. If this doesnt do it then i would make sure the teeth are clean on the gears this would throw a good bit of slack into the system as wel.

 

I don't really have a way to check the flatness. These videos and pictures were taken on my blackberry. I thought they were pretty damn good for cell phone pictures.

Are the cam gears supposed to be shimmed? I laid a straight edge across the cam gears and they are straight. I just feel like you would be able to see a pulley wobble if it wasn't straight.

 

Wobble yes, but magna has a point, although poorly worded.

If the camshafts are not sitting flat in the journals, or at least one of them, the pulley will not wobble, but will be sitting with a titled axis and cause the belt to walk. It'll also most likely ruin your bearings and head.

 

Ohhhh, I see what you are saying. Like, make sure that the gear isn't leaning forward. The thing that gets me, is that this didnt start happening until I had driven the car a few miles. When I first started the car, the timing belt didn't move. Now, it works it way out in several seconds of cranking.

 

DEAR GOD! Tell me that belt isn't as loose as it looks. Exactly how much deflection do you have between the 2 cams? Unless the photos are playing tricks with my eyes, I can see the belt loose enough to curve between the exhaust cam and the idler pulley. Being too loose like that would certainly cause it to walk back and forth like that. I was expecting just a gradual movement to the outside, not a back and forth dance like that.

Yeah, on second thought, TIGHTEN THAT BELT! Does anyone else see the belt wobble on the first video between pulses? If I'm seeing it right, that belt is WAY WAY WAY loose. I know there will be a little slack on the non tension side, but should it be enough to let the belt flop around like that?

 

Yes, but not just the gear. The gear would be sitting on the camshaft flat, but that entire assembly would be tilted.

Like I said, I just did my timing belt and I had wobble like that between the gears as well. I'm going to redo it, but again like I said, it didn't walk.

 

I'm with NA6C. Unless it's just the photos, your belt is loose as ****.

 

Ty curly
yeah wes make sure all the gears are straight up with each other and then make sure you didn't leave a **** ton of slack between the gears.

 

I would say it's time for a new belt. From your pictures, it looks like the belt is barely even touching the idler pulley. How much tension is on the belt at the top of the two cam gears? The belt should require some effort to pull it over both cam gears, and if it just slides over with ease, then perhaps you have a wrong belt that's too big?? But yah, I third the way too loose sentiment.

 

My guess on how it got so loose is he didn't make however many rotations the book calls for. Two full turns or something, to remove any slack on the other spans between the exhaust and intake cam, exhaust to idler, idler to crank. If you just removed slack from the tensioner span of belt, the other part of the belt would likely be about that loose.

 

Did i mention that i am using an ATI super damper instead of the stock balancer?

 

Definitely too loose:



There is obvious slack in the belt there, Wes.

 

Loose as a goose!

 

So, I was missing a part.



That keeps the belt from walking off the gear.

/facepalm

well thank god it will be an easy fix hopefully.

 

rofl i knew it was something simple lol

 

WTF is that, part of the super damper? I JUST did my belt and can't identify that to save my life. Looks like a shift boot or something.

 

The belt is still loose though. Be sure to get it tensioned correctly, its important!

 

its the spacer that makes all the **** line up
