My timing belt is almost completely stripped. I put a new one in at work, and the notches don't exactly line up with the "white" paint on the belt. How do you get them to line up all 3 of them? Like the one on the crankshaft I believe, and the 2 for the cams. So that makes 3 notches.

Help!...

make sure they are all EXACTLY lined up.
these are interference engines, you **** it up and you can kiss the motor goodbye

So you should have it just like this right?





They should be alligned the 2 dots on the cams (almost directly at 11 o'clock for the valve on the left and 1 o'clock for the valve on the right), and the 1 dot with the crankshaft (about 5 o'clock)

Right?

yes...all 3 spots needs to be lined up perfectly.

Evil_Twin

We tried getting all 3 of them to line up. We got the right cam to line up, and the crank to line up, but then we couldn't get the cam on the left to line up with the white mark on the belt.

did it skip timing and now it's slightly off?

i assume you're turning this w/ the old belt still on the motor?

Evil_Twin

Well the teeth on the belt was completely taken off. So I replaced the belt. When we got the belt lined up with the right cam and the crankshaft when it came back around, it wasn't lined up... Really confused about how to get them all lined up. I don't want to "****" up my car.

i assume BEFORE you took off the belt you lined everything up...if not then i'm not sure where are you at now because the motor should have everything lined up before you pull the belt. once the belt is off and you slip the new one back on the marks on the belt should all match/line up w/ the dots.

ish

sorry to jump in but i thought i should ask since were taliking about timing im getting my timing done right now from my mechanic and he says that one of my spark plugs arent firing and thats causing the car to shake or vibrate. are these related and what shouldni do about this.

Evil_Twin

well what happened was that the teeth on my belt stripped, and stalled the car out. It was when I was driving so I didn't know where I was at. If I line the crank dots up, and the cams up it should all be fine. But I just cant line both cams up at the same time.

timing...as in ignition timing or timing as in cam/crank timing (timing belt)?

DanNY

iTrader: (14)

ok so the one tooth stripped...so that means that one cam that the belt stripped on is off it's timing. can't you just turn that back to line it up w/ the belt? is it wayyy off?

maybe it's time to seek professional help?

Evil_Twin

It wasn't 1 tooth that was stripped. Like the timing belt wasnt replaced, so it got dry rotted and all. There was a good 1/4 section that was stripped. I just don't know why we can't get the punch dots to line up correctly with the timing belt.

ish

timing belt cam crank type w/ water pump and belt being installed new. he wants to check compression and stuff to see what would be problem. i think he might be trying to rip me off but i want to make sure everything is good before hand. what do ya think.

well if your timing is off it can cause your distributor to fire at the wrong time...causing misfiring.

DanNY

woahhh...ok i would definitely say to have a pro look at it.

you might have bent some valves. i know why you can't get the dots line up because one of the pulleys didn't spin when it's supposed to because the belt was stripped...hence causing your motor to stop running. good luck.

ish

but why would he look at the spark plugs. i dont know about timing but was he checking the whole car out while doing timing. i dont understand how he got to that conclusion.

If your mark on your left cam is just a little from lining up, move it to line it up with the dimple in the shroud. If it is a long way from lining up you may have to pull the head to check it. When cam pullies are lined up with the dimples and the crank is lined up with the notch then put the belt on with the lines lined up with the marks on the pullys. This is easier with two people. I is a little hard to get the two cams lined up. There can be no slack in the belt between them, it is a tight fit. Also, the only time the lines on the belt will line up with the pully marks is when you first put it on. After you rotate the crank 2 times the pullies will line back up at tdc position but the lines on the belt will not line back up.

Got 'em! The timing belt is directional. It was put on wrong. haha, but it works and my car is awesome! haha. Thanks for the replies and help everyone!

a little logic works every time

how many miles were on the car when this happened? and was it the original belt? just wondering how urgent it is that i change mine...been putting it off with 88,000. not sure if it's ever been changed. i had the original belt rip apart on my old pizza escort at 130k..that was a non interference motor though so it was no biggie. good hellrunner engines in those escorts btw

holy crap...are you serious?!?!

what t-belt did you get????

the OEM t-belt has ARROWS pointing to where out should be.

maybe he had the cranks dot on one of the cams

Yourself

personally i think setting the belt tension and tensioner is the hard part ...if you see it in a f.s.m. its seems real complex ...i think they just over explained it right?seems like it should be pretty damn tite but then a little less (f.s.m shows using a clearance gauge)what did you do?

Evil_Twin

The belt is directional... we had it on the wrong direction. I did get the OEM one though.
