I need to change my crankshaft pulley seal. I've done everything I need to do to this point. I cannot get the pulley off, I've taken off the center bolt and the 6 10mm bolts in the center. The pulley is loose and I can pull it...just not off. The inner fender wall is in the way. Does anyone have a solution to this? Thanks for any help.

Did you remove the inner fender splash guard? Put the car on a jackstand and take off your right tire, I think its 4 10mm screws and you take off a plastic splash guard.

I was able to easily slip the pulley off that way.

Yeah, I had to remove the splash guard to get to the pulley bolts. I pulled the pulley towards me with both hands... And the inner fender wall is in the way. Does the pulley stay in one piece and come off? My buddy's dodge neon crank pulley came apart when I pulled that off. Thanks for any help.

So, what you're saying is just take off the 6-10mm bolts and pull? I don't need to take off the main bolt? Remember...I am trying to get to the seal. Just wondering...

Well there are three separate pieces here that you have to remove. First you need to remove the pulley, which the alt and ps/ac belts run on. This is removed by taking the 6 10mm(?) bolts out and pulling. A baffle plate is installed just behind the crank pulley, and will slide right off. Next is the crank gear, which is a separate piece from the crank pulley. This gear is what the t-belt rides on. You need to remove the center bolt to get this off. It should slide off, but might need a bit of persuasion (might need a gear puller.). The crank seal is just behind the crank gear.

ok....

I get it now, you know what my problem was. I took all of the bolts off and pulled. The pulley and the gear behind it were coming off together, thus making it too large to come off. I'm gonna go out into my garage in an hour or so and give it a try. I will post my results when I'm finished. Thanks a bunch for everyones help/guidance.:)

I got it. I removed the pulley first. Then I removed the gear the T-belt rides on. There was the seal, I used a ground-down allen wrench and a slide hammer, came right out. Cleaned up the inside pop the seal in correctly. Good deal, no problem once everything comes together. Thanks to everyone who helped. :smokin:

I can't say that it was easy. But I would say If you can follow directions and have the mechanical ability to take a tire off, you will probably be ok. The best thing is...if you get in a jam, like I did. You can reference this awesome website MX6.com and ask whatever question you might have and someone experienced will answer. It's the best. If you do try it though, while you're at it you might want to change the Cam pulley seal too. The 2 seals are the exact same and it will leak if it's not already. They come out the same, and the belt is already out of the way for the crank shaft seal replacement.

seal replacement

The crank and cam seals are often overlooked, but with the age of our cars.......it's wise to check and replace this stuff whenever a new t-belt is installed. Also, this is a good time to check the idlers, sprockets and pulleys for signs of play or wear.

If you do this, it would be a good time to replace the T-belt, idler, idler spring, and water pump as they are all important parts that wear and can cause major problems if they fail. And since you would have to remove all that stuff to replace those parts later, you'll have 60K miles before you have to remove the parts again. While you are in there, do all the preventative maintanence you can.

yeah i thought about the cam seal too, after i went and bought the crank seal, as far as the timing belt goes, i'm probably going to wait till it breaks... since all it would do in our cars would cause it to stop running. but as far as the seals go, they are leaking at least the cam seal is, so those are my priority, i'm not a rich guy other wise i'de replace everything there, actually i'd probably just buy a fe dohc, and i've taken off my timing belt b4 and put it back on and also changed my tranny to axle seals so this should be much diffrent, thanks for all the advice anyways.

and i agree this is an awesome place to get some good help when u get in a jam while working on your car.

I cannot believe someone would go to all the trouble to change a cam/crank seal and re-use the old timing belt! I don't mean to offend here, but if you can't afford $30 for a t-belt, how do you expect to keep your old car running? You don't have to be "rich" to perform basic maintenance. Just wait until that belt breaks on the way to a job interview or on the way to the hospital.......

You make a good point, only reason i was going to hold off on the belt is cuz i always do more then i should when i work on my car, i just wanted to stick to the problem, didn't know tbelt was only 39.99 but then again if i'm gonna change taht i might as well do the tensioners and water pump too... thats why i'm holding off...

Value of time and better use of it ......

It's only good sense to do as much as you can while into it, especially if unknown when last belt replacement was. The frustration of tearing it apart after breaking would upset me.
Especially if those seals were oozing oil onto the belt's surface for any length of time. Why even bother replacing the seals until the belt breaks, then do it all.
Just my 2 cents for better sense. No offense, dude !
