Front crank pulley removal. Difficult?

Seems like it would be hard to remove if you have to use a puller. Can it be taken off by hand or gently tapping it?

Considering putting on my lightweight pulley. And since this one is a press fit, is the aluminum pullies hard to get off?

My crank pulley was VERY DIFFICULT to remove. We moved the radiator and condensor and went through 2 impact guns without success. Ended up leveraging a breaker bar against the ground (make SURE it's on the driver's side!!!) and cranking the engine to break the bolt loose. Unplug your coil packs before trying. It's scary but it works. The front of the car lifted up 3 times before breaking loose.

sounds dangerous.

i tried taking off my pulley last night and no luck. i read about the method of putting the breaker bar on the ground but god that sounds like im begging for catastrophe. any other suggestions on getting that thing off?

The OEM pulley should slide right off the crank snout, assuming the crank and pulley are cold. It is not press fit. Are you sure the aftermarket pulley is a press fit? It should be, but you will need a puller to get it off because they tend to wedge themselves onto the crank key slightly. Just a couple of turns on the puller and aftermarket pulley will come off. Make sure to replace the crank oil seal while you're in there.

Good luck breaking loose the crank bolt. You'll need to lock the flywheel and then get a huge breaker/cheater bar. It will be a two man job.

You need a chain wrench and a beefy breaker bar. My tech went thru two broken breaker bars to get my oem crank pulley when swapping out to a ATI crank pulley.

Not too hard. Use a breaker bar & use extra extension via the floor jack handle. Make sure you use a 1/2" socket not a 3/8".

Remove the ignition fuse located under the drivers kick panel. The fuse was the top left, IIRC.

Once you get that nut loose the crank pulley just needs a little persuasion to come off. Has to come off evenly. If you have a rubber mallet just tap it a little here and there and then use both hands on either side and pull it out evenly.

Loosening and removing the pulley was not too difficult. Putting it on was more challenging since it's notched and needs to be lined up with the crankshaft. Took an hour total. Good luck.

Use some white lithium grease when you install it.

I know this is late but I found a cheap easy way to remove the crankshaft bolt. I went to Lowe’s and bought 2 feet of 3/16” steel cable and 2 1/4” wire rope clips. Fed the cable through the pulley and used one clip (with enough cable to use the 2nd clip as well). Hooked one end of 10,000lb tie down (I know, overkill) to cable and wrapped other end around frame on near side and hooked on frame on other side of engine bay. 2 foot 1/2” breaker and impact socket pull and off first try. Had the tie down and the Lowe’s purchase was less than $7

The easiest way is to just use a big enough air wrench to impact the thing off. The Ingersoll-Rand 2235 TiMAX 1/2" drive is rated at 1000 ft/lbs reverse and 1400 ft/lbs forward and it will knock off even the most stubborn bolt in a half second. Electric impact wrenches are usually in the 300-400 lb range and just don't have enough kick to EASILY get a lot of bolts off.

True but if you’re trying to keep the pulley from spinning I’m not sure more torque equals less spin, or less chance of engine damage. I was a dumbass and had everything taken apart and just had the crankshaft bolt to remove so I could remove the front timing chain cover. It was a small exploratory fix that just kept getting deeper.

The crank pulley won't rotate at all with an impact wrench, torquing the bolt back down is the only time you need to support the thing. I typically use either a piston stop or a ring gear lock, I was hesitant about using a piston stop on this motor though (I don't use them for larger engines anymore only small engines like lawnmowers and such) and couldn't find any good alternatives last spring when I was putting an underdrive pulley on the neighbors car so I ended up buying the Kent-Moore one which was a little over $200.

There's a lot of ways to keep it from turning though and if it's a 6MT then it's REALLY easy, just put it in 6th gear and set the parking brake.

I would think a good breaker bar and a hydraulic jack could break it loose assuming there is enough room underneath.

Borrow a big impact wrench from somebody.
