Gah - shredded crank & pulley

[idosubaru]

Bought a 1995 Legacy EJ22 for my grandmother and when putting new timing stuff in it, i noticed the crank pulley was severely damaged. It wobbles a bit while running, but did run and drive fine.

 

So...i'm not doing a motor swap considering it runs and drives great. I'm thinking just get the pulley as flush as I can and bolt it on tight. Maybe some non-permanent lock tite. I've done this before on other cars, I can get it tight enough to not come off even though the key is completely gone.

 

On first check it seems like a new pulley isn't going to want to sit straight on it, that might be the hard part. It was running the belts fine and considering she drives 5,000 miles a year maybe that's okay, replacing those once a year isn't a big deal.

 

Any other ideas? I'll post pictures when I get into it.

 

I know there's a crank shaft fix kit for this but not sure i need all that, but i'd like the link if anyone has it (i've even posted it before for others !)

i'd put on a good pulley, it's seems to me that its more likely to cause the wobble than the crank. clean up the crank, good pulley, lock tite and torque it on.

 

the biggest down side to failure is your granny being stranded.

 

good luck.

right on, that's not really an option. like i said, i've installed crank pulleys without keys before so i'm not that worried about it. iron crank - iron bolt - i've never had one strip yet with some serious stank put on them.

 

i'll try again - looked like the new pulley wouldn't seat but hopefully i can get it to work. it was "working" before so i figure i can at least make it a bit better.

There is a fellow on this great website that helped me out of the same dilema.

He had a clever fix that required so tool room work.

He tied the crank timing gear to the drive pulley with 2 rollpins 180 degrees apart.

Machined properly this new one piece unit snugs up tighter then the hubs

of hell. I Had an old cigar chomping machinist at work do mine up and been driving 30k + miles.

Wish I had saved the guys correspondence.

 

Wait, I found the hardcopy in my sube manual.

thanks rick, i did find it. i will attempt that fix - i could probably print that picture off and hand the parts to my machinist. thanks!

someone PM'ed because they couldn't find that post. under the advanced search function search for posts by user "WAWalker" and i used "crank pins" for the search words - it came up a few down the list:

the only problem i see with mine is i can't seem to get a new pulley to sit flush on the crank for some reason. i'll inspect that more later though. getting it to stay won't be the problem, getting it to line up i think will be the issue for me.

New pulley may need the inner surface of the mount hole machined slightly. Slight differences in manufacturing can cause that.
