Re: 3.4l crankshaft sensor install.....

you need a puller,i doubt you can get the pully off without it.i replaced mine last summer.its pretty simple once you get the pully off.

Re: 3.4l crankshaft sensor install.....

You should be able to pick up a puller for about $15 at a parts store. The center bolt has to come out too. The process is fairly simple by just following the instructions that come with the puller. I belive it took me about a half hour total. That center bolt might be difficult to get off because the pully will want to turn when you turn the wrench. I used an impact wrench and if you have access to one you might want to use it.

i cant get the center bolt to even budge and i dont have a way to get an impact driver is there any other way you know of to get it out ive tried all night and almost threw out my shoulder from it even

The only other way is to lock the ring gear with a pry bar or a screw driver. That way the flywheel will not move and you can loosen the bolt.

wait a minute how do i do that?

Re: 3.4l crankshaft sensor install.....

Where the starter gear contacts the flywheel there should be some teeth visible. Stick a screw driver or a crow bar in those teeth to hold it. You may also need a cheater pipe for your wrench. This will probably be a two person job.

Re: 3.4l crankshaft sensor install.....

i absolutly could not get the harmonic balancer off even with a puller so how much do you guys think it will cost me for a machanic to do it?

Re: 3.4l crankshaft sensor install.....

Do not use an impact wrench with the puller. very well could break it. use something else like a wrench :)

Re: 3.4l crankshaft sensor install.....

i used a rachet on the puller and it still wouldnt work im thinking tis the wrong puller because only two of the 3 bolts would actually fit through iut and go in the harmonic balancer? could the be the problem

Re: 3.4l crankshaft sensor install.....

I did a cam interrupter install last night / this morning.

I was able to pull off my harmonic balancer (on a 3.8L and I've done it like 3 times before). I only used 2 bolts of the 3.
I've noticed that on the 3.8L's harmonic balancer the 3rd hole doesnt go all the way through like the other 2
good luck

Re: 3.4l crankshaft sensor install.....

could it be that i have the wrong puller like i have 4 holes on my balancer and can only get two bolts in because the puller isnt alligned right for another one, i might try again next weekend when i get the time?
