totaly screwed up ,please help

[shodazzl]

Ok ,I have a 93 atx and I was changing the timing belt .I knew about setting the crankskshaft white mark tdc o,and top timing pulleys at 12.But after I did the start er"bump mtehod,I took the dampener pullery off relized that I did not reset the timing crank pulley at "5" and top two pullys at "12" after that.ALSO..... I removed the tensioner (screwed uppp)then tried to turn the crankshaft with the crankbolt but then the belt skipped a few teeth and now the top timing pulleys are not completly matched up and likely the crankshaft pulley ,right? eek! DID I totaly screw up?How can I get it back to they way it should?

Woa, ok give me a second to picture this. I am not sure what you mean by pulling the tensioner, do you mean the accesory or the timing. If you did the timing one, you might have messed up the spring sense it requires a constant load otherwise it completely unravels.

On the other stuff, you do not need to reset the crank pully position sense there is a key used to line it up. (when the engine stops, the crank ends up in the same position always, unless there is something major wrong with the internals.) So that should not be a problem. As for the cams, did you do the valve lash? If so it should have lined back up to the original spot. That is why there is a guide pin on the cam sprockets to put it on. If it is not lined up, grab the rench, pull the belt off and start turning the cams again, put the belt back on, and you should be good to go.

dude, you're fahked. I think you're gonna need a rebuild. Just kiddin'. If you are worried about the white marks not lining up with the dots on the pulleys, don't worry, they won't after the engine has been turned. I went through the same panic/confusion before the good folks here helped me pull my head from me ****. Get the cam dots at 12, the crank dot at 5 (mine was really hard to see, you may need to clean up the pulley with some emory cloth). Put the new belt on with the white marks lined up with the dots. Take a picture, you will never see these things line up again after the motor is turned over. I don't know a thing about the ATX motors tensioner, so I won't even go there.

dAMN PETE i ALMOST HAD A HEART ATTTACK
Here's the second picture.I wanted to line up the pulley marks .The tensioner was not installed and it was compressed and set aside(main mistake).Then I tried to rotate the pulleys with the crankshaft bolt but the belt statred to skip teeth making the top 2 pulleys off from one another. Aren't they supposed to turn and have the dots at the identical place as the other pulley. Say is at 3oclock,the others at 3ocolck etc.Ok the crankshaft pulley is fine but how CAN I turn the top two pullys? Eric, Yes I did do the valve lash and I put everything back on. I don't know about the guide pin on the cam sprockets to put it on .(put the belt on?)I guess I'll try to turn the pulleys back,without the belt on, but can someone tell me how to do that?

Ok I took my timing belt off I i turned the pulleys withmy wratchet the right pulley end ed up at the 12ocolk position,It seems to be under spring pressure it stops and sits, for every turn of the wratchet like a spring load.I tried to do the left pulley but it just springs past the 12 oclock mark every time.Ihave not been rotating one more than the other .Why is it not letting me to leave it at 12ocolk.The spring pushes it forward?why?How can I fix this?Please Help..

That spring pressure you feel when you turn the cam pulleys is the result of the valve springs compressing and is completely normal. It is a PITA, though; I know how frustrating it is to spend half an hour just trying to line up the cam pulleys.

Turning those cam pulleys with the belt off is also a PITA. What I do is put the timing belt on one pulley at a time, then use it to adjust the cam sprocket to where it should be. I don't know if it's good for the timing belt, but mine needs replacing anyway, so I just do it that way and hope the belt holds out.

To line up the bottom end, you have to line up the dot on the side of the crank sprocket with the tick mark on the oil pan at roughly the 5 o'clock position. When you put on the new timing belt, make sure the writing is facing correctly--that is, readable from the driver's-side fender, with the top of the letters facing the passenger side of the car--and that the marks on the belt line up with the marks on the cam and crank sprockets. Make sure you tension the belt properly (don't know exact torque specs), then button it all up.

And be careful reinstalling that middle timing cover. Don't try to force it in place or it'll break, probably in more than one place (don't ask how I know ).

Ok,Let me get this straight, so,What I have to do it keep on turning the left timing pulley until it eventually lines up with the spring load at about 12ocolk.Its not lining up now cause the sring causes it to jump past 12 so will it eventually end up at the 12 position?????

You just have to carefully set it there. The springs will never change, it will always try to spring past. Just go slowly

Highly recommend you buy or borrow a 6" BOA rubber strap wrench. Using the old timing belt might work out fine as suggested, but the strap wrench was the only way I could control the cam position without it "falling" off. BTW the rear one gave me the most trouble. Just make sure to only turn the cams clockwise. Good luck.

 

[Chrisssssssss]

I agree with the BOA thing. That was a lifesaver when I did my timing belt when I swapped engines.

Excellent Guys, Thank You.I'm giving it a try.Couldn't have done it out without ya.I'll post on the results!
