WTF happened here?!

Budfreak · #1 09-27-2005, 10:02 AM

ok so i got a stock pulley from svxfiles and when i went to put it on i found out why mine was wobbling. the little slot the crank key slips into on the pulley has been gouged out to 3x it's original size and the key on the crankshaft is cocked sideways

i just don't really know what would cause this to happen like this. i can't put the new pulley on because of the crank key being bent off to one side. i tried to get the key to straighten out but it's just not gonna happen. what am i gonna have to do to replace the key? i don't know how i'm gonna get the crank gear off with the key like that so i'm kinda screwed right now. this is my only day to work on it so some quick responses would be great. thanks guys, Jason

If you can take some pics as it'll help people trouble shoot your issue better...

That's a difficult problem to fix. I really hope that all goes well for you.

I think you may have to use a puller to get the pulley off the crank shaft. There could be problems with this method. The crank shaft could end up getting damaged if the key doesn't straighten out.

Was the bolt loose? I think this damage could start if the bolt came loose.

Another possibilityis the ac, ps, or alt siezing up and twisting the crank pulley. The belt would have to have been real tight for that to happen.

Is the pulley loose on the crank shaft? If it is the shaft may be damaged.

i'll probally need a puller for the timing gear but the pulley comes right off. we figure either the bolt came loose at some point in it's life or like was said something froze up but those belts would have had to been plenty tight. but that is what kinda looks like happened though

i'm gonna pull off the gear and find a new woodruff key and put on my new pulley and hopefully all will be well. i'll let you all know how things are going. i'll take pics when i get out there and get it all apart. wait till you see this

ok so heres some pics of the chaos. it's kinda hard to see but the key on the crankshaft is bent pretty good and you can see the great big opening in the pulley that should be no bigger than the crank key. this is gonna suck

That looks like one of the many things that happened with the Teg except my bolt was gone before the key was turned to dust replace the key and the pulley and hope that it didn't bugger the end of the crankshaft. also the pulley and key took all the damage on the Teg.

i think everything is ok. i'm gonna use a grinder on the key so i can use the gear puller i just got to remove the gear and put in the new key and then i'll put the new pulley i got from svxfiles(thanks tom!) on and should be good to go by tomorrow afternoon. what caused it on your teg? i wish i could figure out what caused mine to do what it did. if you notice in the pic, you can see the shape of my crank gear impressed on the back of the pulley. it's more deeply imprinted on one side which is why it was wobbling.

why do i always get the cars that have had the crazy things go wrong with them?

i'll report how it goes tomorrow.

Don't have a clue got into the driveway for the battery to die(no alternator with no belt moving it) got uunder the hood the net morning to fing the bolt gone. no evidence it had been there for a while either

the only thing I can even begin to think of is it came off some time after my father and I replaced the head(have to remove all the pulleys and even a motor mount to get the timeing belt cover off)

I had the same problem and my belts actually let loose. Being close by I went to the dealer just running on the battery.

My ass still hurts from the raping but the guy did a good job. My pulley had the same keyway problem and he told me he had to pretty much make some ghetto key to hold the pulley on there. He also stated to make sure I always have that bolt torqued down to spec and spit me out the numbers. Of course if would help if he supplied me with the subaru tool to hold the dam pulley. Good guy though but oh the dealer sucks - I was pissed when I got the bill.

Good luck

ok now i'm screwed. the gear puller just broke the timing teeth off the back of my crank pulley. don't know what to do but sit here and miss work. I"M SCREWED!

svx_commuter · #11 09-28-2005, 10:51 AM

Oh crap that's not good. The holes in the T-sprocket need to be tapped for bolts. The puller then pulls on the bolts and not the back of the T-sprocket.

Budfreak · #12 09-28-2005, 11:00 AM

well, there may be a 92 for sale on here soon. the gear is shot and the POS puller screwed up the threads on the crank too. couldn't do it with the bolt in cause it was too long and was hitting the radiator. well, i think i'm screwed and it's over cause i can't afford to fix it. either someone volunteers to fix it or i'm screwed cause i'm not dealing with it much more than this.

Beav · #13 09-28-2005, 03:51 PM

Obviously the puller isn't what fouled the threads. Sounds as though it's time to let someone with more skills fix it before you cost yourself more money. It isn't the end of the world and the repair will cost you less than selling cheap. No, the crank doesn't have to be replaced, and as long as the key slot isn't damaged, doesn't have to be removed.

Sorry, I can't make the truth less painful to hear.

sorry partner but i got all the skill i need. the pulley is off and all is well. just waiting for parts to come next day air delivery from subaruparts. i cut that ****er off with a rotozip and it worked great. it should be running like new by friday at the latest. pulley....check crank sprocket...check woodruff key.....check

looky what i did

i'll take care of the bolt thread situation tomorrow or friday, it won't be a problem either as it's just the first thread or so that's messed up.

Beav · #15 09-28-2005, 04:57 PM

Glad to hear that! Unfortunate that you didn't grind the key down first. Hope the crank slot is in good condition. Make sure the bolt is torqued down so it doesn't happen again.
