Pretty sure the shop screwed this up big time!

Just had my timing belt replaced two weeks ago, truck ran great till memorial day they started stalling at idle and when stopping. 3 days latter it just died completley and wouldnt start back up. Thought for sure it was fuel pump. Replaced that today (damn you toyota for not making an access hatch!) When I went back to the from of the truck i noticed my ac belt and hydraulic belt were shredded and there was a chunk out of the crankshaft pulley. After taking the belts off I noticed that the crankshaft seemed to be sticking out a little to far and wasn't lined up right with the pulley above it *causing the belt to be pulled to the side and catch the rough chunk that is missing)

How hard is it to put the pulley on correctly? or should I just take it back to the shop and raise some hell?

I dont even dare start the truck to see if the fuel pump is what my problem was and is working correctly now or if this CS pulley being out could have been my problem with stalling and not starting?

The piece of crank pulley is the least of the problem. Call the shop and ask them to tow it there to fix it. They may not have torqued the CS pulley bolt correctly, if at all. Worse case scenario is a ruined CS.

Thanks for the reply. Anyway easy way to tell if it ruined the crank shaft? Also would that cause stalling and then a no start situation?

Attempt to Pull the crank pulley off. Look carefully at threads. Check timing of the belt, could have slipped.

I personally wouldn't do anything so the shop can see how they messed up and not blame you for the damage.

I agree that you should not touch it and have it towed back to the shop. Ask them if they torqued the CS bolt to spec 217 foot-lbs., or ask them if they even know the spec. This happens frequently with shops that just hit it with an impact and call it good. 217 is a pantload of torque.

It is for sure a loose CS bolt. What is probably happening is the crank sprocket has slid forward enough to lose communication with the Crankshaft position sensor, totally confusing the ECU. Those little teeth on the back of the sprocket are magnetized and provide the input to the sensor.

You can't tell for sure if the CS is buggered until the bolt is out and the pulleys are off. If you can wigggle the CS pulley on its shaft that's a bad sign, but it is more likely the shaft is ok and just the pulley is buggered.

Off of what Durk said I would want to see the CS, keyway, and balancer/pulley when they have it apart to see if any damage was incurred. I would at least get them to replace your pulley/balancer and the keyway. Maybe a new CS bolt too.
Hopefully, it is exactly as Durk said and it just slid forward. You are very lucky as there are more than several posts and pictures of this exact scenario where the CS was damaged (because it moved totally off the keyway and spun on the CS) and basically meant the motor was toast.

Thanks for the reply guys! Im really hopping it just slid forward. The shop manager is supposed to be calling me back shortly to talk about it. If it did damage to the crank i guess the shop is going to tear apart my engine for free, because im definitely not paying for this repair. Ill keep you updated.
