separating / unscrewing the two pieces of the crank pulley?
 

I've searched, and searched, and searched all night, and I can't find an answer to this question... (and I couldn't find anything in my shop manual earlier)...

I have a new motor for my car but the previous owner wasn't running PS or AC so the outer portion of the crank pulley was removed (makes sense), well I plan on doing a lot of auto-xing in the near future so I'm retaining my PS (for the time being at least) and I need that outer pulley unfortunately. My old motor still has this pulley but for the life of me I cannot get it off! I think it would be easier if the motor was still in the car (I didn't notice until I started swapping parts over to the new motor and realized there was no pulley in line with the PS tensioner :lol: ) but I've since pulled it.

I've tried a few tricks but just can't seem to get it to work. I'm assuming it is NOT reverse threaded? (didn't think to check when I was working on it) I'm also assuming that it DOES unscrew as it appears to do from looking at the inside of the pulley on the new motor.

Granted this is probably not a common problem, does anyone have some pointers for me? I was also careful to use every term I tried searching with just in case someone else has this same problem in the future they should be able to find this easier...

Here you go, for starters DO NOT undo the large front bolt just take off the 4 small 10mm bolts and it should just come right off.

Hope this helps.

I did, had to remove front cover. Good thing though, there weren't any thrust bearing washers installed, saved my motor finding it now instead of later.

i don't remember the removal of those bolts to be an issue. is the eshaft spinning on u? i think i used a chain at the flywheel to lock the eshaft in place.

Well I haven't tried removing those four bolts, from the fear of damaging the bearing behind the front cover (torrington?). The e-shaft is definitely spinning, the motor is out of the car, nothing to hold it in place (I'm by myself in the garage). Is it ONLY the larger bolt in the center that will allow the e-shaft to shift and potentially damage that bearing? I wasn't entirely sure on that so had moved on to separating the two pieces of the crank pulley itself. If I can just take those four 10mm bolts off and swap out the two pulley assemblies that would make life 100x easier, but I'm still kind of interested in knowing how people separate the two pieces of the crank :lol:.

yeah the large bolt is the only one u need to worry about. i just looked at my crank pulley.. its just 2 separate pieces.. same 4 small bolts hold them together :)

Damn you are right, I was comparing the two and the one on my new motor (missing the second piece) is threaded on the inside, I guess I just assumed the other one threaded into it... and that's what happens when you assume things... Had a chance to get out to the garage tonight and got it all swapped over.

well for future reference (I still couldn't find a thread that discussed how to separate the two halfs) you do just have to remove those four 10mm bolts and the outer pulley comes right off no problem...

Thanks guys, appreciate the help! I'll go back to my corner now and try not to ask anymore newb questions :( :lol:.

Not that I need mine apart, but I went out to the garage and tried to pull mine apart by hand and they didn't seperate....I think someone gorrilla glued them together or something. :lol:

:lol:, that's weird, mine came right off with minimal force using only my hands :tonque:...
