Great write up, allowed this one
guy to take this job on. Bearings went out in my fan bracket and while removing the parts noticed a problem with my TB. I found what looked like roller bearings wedged in the crank pulley. i am replacing everything with new parts , but where did these come from?
Wow is right, could those be alignment pins rather than rollers? That is some big debris for the belt and pulley to eat and remain intact. Is this her second TB job by chance or all original?
Well...
Looks like a real testimonial about how robust these belts are. Pretty impressive really.
Should be on a poster entitled, "Dodged a Bullet"

I agree with "dodged a bullet" glad I found it when I did. First TB was done around 90k (dealership) and the second was done at 182k, but I am now having doubts if the second actually got changed. Just shy of 200k now. The second change was done about two years ago by a friend of a friend opening a new garage/business. In hindsight I did not vet him well enough, because i have found a couple aftermarket parts during this surgery. I am not an expert on parts but i assume if they say "made in china" it is not OEM. The fan bracket that started this was one of those parts, but the bearing that failed were different than the pins I found. Anyway the TB pictured is clearly OEM. So I wonder why he would mix parts. I drove by his shop the other day and his business is no longer there. Really I would just like to gain some in site from him on what might be spewing pins so I can replace it. I am replacing everything with new so I am probably covered, but don't want to leave anything to chance. Obviously a crank pulley was not on my pre order list so I have time to investigate while I am waiting for the part!
I'm helping another Mudder with his timing belt today. Well, I'm a half banana mechanic, so not much help. Mostly trying to learn. This is a great thread. After reading here, and helping on this one today, I'm realizing that this task is more manageable than I thought it was.
For sure man. I just did the job last month and I knew nothing about timing before that. It was intimidating to think of what could possibly go wrong if I screwed up. But, with the help of this thread and the knowledge of others it was really just a bunch of nuts and bolts to keep track of.
Great thread! I did my girlfriend's timing belt this weekend, which was her first timing belt service after *200k* miles. You can imagine how much sh*t I'm giving her for neglecting stuff like this. Anyway, the belt looked pretty darn good for that amount of miles! No damaged teeth but there are quite a few hairline cracks on the backside. No guess how much life it had left.

Got 2000 lx... Just did my timing belt. Was super easy considering what most people say, I replaced everything I could. Seals, tensioner, idlers, pump etc... Followed this thread for advice. Was very helpful... Seemed the OP had tough time with the two bolts near the oil filter... Here is the easy way to get at the lower one. I have lots of longer extensions for bell housing bolts and they proved there worth again... Turn wheel driver and insert extension through lower control arm and it's super easy... Practically finds the bolt by itself...
Here is my crank bolt removal tool... Also helps in aligning fine adjustments for belt install... If you use just the crank bolt you can only adjust it clockwise... And the starter bump method works but leaves you SOL on the retorqing to spec... Other than that the job was a breeze. Highly recommend doing it ur self, not hard and it's near impossible to mess up if you pay attention. I like to use painters tape and a sharpie and tape bolts together for easy re assembly.
Another shot of tool in action
Also I did this with small hose to clamp off tranny coolant ports... I clamped the other ends as we'llwe'll
The other side...
Spoke too soon! So the truck ran great in the driveway... waited for warm up and went down the road fine. After a minute or two of driving i got a hesitation... loss of power. Came home and checked codes... P0300, P0310-304. What the heck!!! I did not mess up routing the wiring, it all seemed to be intact. So i tore it all down again, checked my lineups and it seemed good. Even pulled the belt off, lined it all up, gave it @ revolutions by hand and was still lined up good. What do you guys think??
Check your crank sensor.
I don't know what this code is: P0310-304? You sure of that?
Start with everything you laid your paws on. I would be looking very critically at the crank sensor.
typo... p0301 302 303 304
What exactly would i look at with the crank position sensor... The wires are attached. Do i need to find someone with an oscillations reader of some sort??
So the codes all together were p0300, p0301, p0302, p0303, p0304
Did you look up those codes?
You have an ignition issue.
1/2 of your cylinders are misfiring.
Did you make any special observations about the crank sensor before taking it off?
You usually want to note everything about the sensors position and I usually measure the air gap if possible.
It's been a number of years since I did mine, so It's not fresh in my head.
Did you disturb any spark plugs or coils?

p.s. also the fact that you have exactly 4 cylinders misfiring would cause one to look VERY critically at the cam timing to see if one cam is mistimed.
