Bad crankshaft gear/sprocket????

[jfunk3367]

Alright i finally got the crankshaft pulley off and all the timing components. After I removed the crank pulley i noticed that the sprocket or gear that holds the timing belt is flat on one side of the lip. The teeth are fine in the gear just the outer rim or lip is flat or wore down. The entire thing is symetrical except one side. This would be the culprit for a gash in my timing belt.
Can that gear or sprocket be removed and replaced without jerking the crankshaft out. Also my car was rattling could this be the cause ??? 2g 420a n/t

It can be removed without taking the crank out but it takes a special puller to do it.

thanks that gives me hope..... haha Does anyone know where to find another crank gear/sprocket I have done several searches and unable to find one

Anyone. I have searched the web, i have called three auto parts store. I dont even know the correct name for the gear. I seen something similiar called a crankshaft oil pump pulley. I seen another call it a crankshaft timing belt gear. What would you call it. Where can you find it. Someone help with this.

If anyone needs a crankshaft sprocket for a 420a n/t the part # is m04667604.
Thanks to a great moderator snowborder714 he informed me to buy it from extremepsi.com and it was $35 shipped

come on guys. I need some help give me some info.
The crankshaft gear is worn or been broken for the rebuild previously,when removing it. Can this cause a weird rattling noise or clicking. I am tempted to install all the timing components again and see if the noise is still there. Can idler pulleys or tensioners cause this noise. I am almost positive it can. I am just tossing up between buying a cheap rebuild kit to get a water pump and oil pump with all the hardware or just buying the timing belt with tensioners and pulleys. I know that its either a pulley or that sprocket that has went bad or the dreaded spun rod bearing. So i thought if i just buy the rebuild kit I would be prepared for both

Thanks jfunk3367 and snowborder714, I was able to locate the same part after my crank gear was destroyed by a runaway bolt in the timing cover.

I couldn't find the part on Extremepsi.com, but I managed to find it at hhttp://www.trademotion.com/partlocator/index.cfm?action=searchCatalogOEM&siteid=213764 by google. Now I just need to figure out how to remove it!
