Crankshaft pulley

[gtfireftr]

Are there threads on the crankshaft in order to use a puller to remove it. I am changing the timing belt and water pump. 1997 v-6.
TIA

You need a special tool to remove the crankshaft bolt. You can make one yourself or buy it from Snap-On for big bucks.

I'm assuming you are doing the timing belt change. Here is a video I found explaining the process.

There are threads inside the crankshaft which the crank bolt threads into to hold the harmonic balancer on the crank. Use a cheap balancer pulley removal tool such as from HF or the like. Some stores even rent them.

So once the bolt is out the balancer will slide off the crank without a puller??

It may or may not. Depends if it's rusted or not. Mine would not come off at first but after I sprayed it with some penetrating oil and let it sit, then a couple whacks with a small hammer and it slide right off.

I used a chain wrench to kept the harmonic balancer still while threading the bolt on and off. But once the bolt is off it should slide right off. Personally on mine I had one Hell of a time trying to get it off. I have a California rust free vehicle but still it took a huge pry bar and a few taps with a bfh

Attach two bolts (that thread on to the pulley) to the ends of a chain (about 8 inches). Next attach the two bolts to the crank pulley. You can now pull the chain with a leaver. If you have your radiator removed, You can use about 2 feet of cable for this purpose and using a heavy hammer to strike the chain, you can pull the pulley out.

I bought a cheap one from amazon for 40 dollars before knowing that you could just rent them at O'reilly's, etc. Use the tool so that it braces against the frame rails, and you'll be good to get the bolt off with a breaker bar. Remember those 6pt sockets...

Here is the tool i made to hold the pulley while working it on/off

(4 bolts holes for the pulley, 1 hole for the socket, bolt it up and go) i used 3/4" hardwood flooring. no stress on it at all.
Oh, and make sure you have a torque wrench that goes to 250 n-m.
