Rep Power: 192

So I replaced my timing belt last summer (about 10k miles ago). Today I was bred so I decided to adjust my valves and took a good look at the timing belt.

On the edge, on both sides, it almost looks like it's been rubbing on something ever so slightly. I can't tell where it's been rubbing. It may not be rubbing at all, I'm not really sure...

I took a couple pics...

Is it supposed to be off center on the cam gear like that?

I was in a hurry and used aftermarket parts, the belt is Dayco and was made in Italy, water pump+tensioner made in USA.

Otherwise the belt looks fine...

Looks average to me, they don't HAVE to ride in the center.

The pulleys with sides and guide plates keep the belt from riding off the edges of the pulleys....so as long as the belt isn't hanging off the edge, it is ok....

unless

I would worry if I pulled the timing cover and found a bunch of black powder from the timing belt, that would be a big problem. That would mean something is forcing the belt to ride to one edge or the other, the guide is working too hard to keep the belt on track. (bad water pump or tensioner, one of them would have to be crooked)

HTH

Yeah I didn't see any bits of belt on the upper cover, I didn't remove the lower cover though and that's where they'd fall.

When I rotated the motor I could see the steel core on most of the belt, however there were sections of the belt that look fine. So either the belt had some wide spots or the water pump/tensioner has a slight wobble. I would think something is wobbling.

Looks like I'll be doing another timing belt using OEM parts when I get the cash....

Stupid aftermarket junk!

On a positive note, the valve adjustment went well and the motor is noticeably quieter.

The timing belt does not have any steel in it.

You may be seeing the nylon threads (or whatever they use) and it is normal to see some of that in various spots of the sides of the belt, and due to the construction methods, it does not have to be evenly placed.

If your concern is "wide spots" (miscut?), leave the upper belt cover off and run it and watch the belt go around for a minute or two...You should be able to make a visual confirmation if there is a problem that way, it won't track true and straight as it goes around.

Like I said, your pic didn't show me anything I thought was scary.

Factory parts can be had for (what I consider to be) a reasonable price.

Yeah the nylon is what I'm seeing then. I didn't see any fraying or anything that looked like the belt was being ripped apart so I'm not sure it's even rubbing...it may have been like that from the get go. I should've paid closer attention to the belt when I put it on.

I'll run up to the parts store and take a look at a new one tomorrow.

The belt stayed on the exact same track on the cam gear when I rotated the motor by hand, never tried to start it up though...

I'm just paranoid with timing belts, I don't wanna kill my motor.

seems fine for me after 10k miles
