OK you need channel lock needle nose pliers. use a big screw driver as you can get in there to put pressure on taking it out while you twist. You will have to put the twist and the pull at same time. This is the only way to get it out besides bits and pieces.
I did some extra checking for you and found the rand r for your crankshaft sensor.
Open. http://www.mediafire.com/?zzgq1cf91u961qg It may be a bit of waiting for the penatration oil to work now that you have twisted a bit and put some lube on it.
But pull and twist. when it comes out it wil act like it was neve stuck.
If reusing the old sensor, Inspect the O-rings for cuts, cracks, tears or
damage, replace as needed. I have been told there is only O-ring at the top. I have the sensor out as far at the space for the O-ring (around 1inch or so) at that time is would spin freely and you could push it in and up to that point, then it's like it hits a wall and stops. Non of this makes sence, if it's the same as the new one, it should pull out. Now I am trying to find out how far past the block does the sensor stick out at the crank, I'm wondering if the sensor warped and is now caught on the end of the block and is trying to shave part of the sensor? also, is the hole in the block a smooth bore? From everything I have read, the sensor should be out by now. I am trying to find a motor out, pictures of the motor with the crank sensor sticking through etc, I need to know what I am up against. I have a friend making a bracket to weld on to the end of a vicegrip that matches the shape of the sensor and fits under the flange that rested on the block, this will give us 100 percent grip and no slipage, then something to pry on.
Greetings and Welcome to Just answer.
How far out of the block do you ahve it?
Ok, does it push back in?
The way I do them is I twist when seated still then pry out with a small screwdriver keeping it straight.
We do have a tool, we took a connector and attached a wire to it so we can connect it and pull on that.
Can you get a loop of small rope around it and then pull that or rig it up so a prybar pulls on the rope?
As of now we have not tried to push it back in after we started to pry. Before this it moved with ease. You used a connector with wires to pull?, my connector is now broke with 3 tabs sticking out. Do you know how far the sensor sticks through the block at the crank? From what I have heard and read, mine is doing something others have not. I did have 1 Tech tell me that the end could be swelled up from heat, thought he said it was like the 2.5 motors. Is the hole smooth from top to bottom?
Yes I did try the rope idea, the rope popped off twice, I had a ton of PSI on it before it came off. We are taking a vise grip and welding 2 half moon pieces to the end to grab under the flange that rests on the blocks so it does not slip while prying. It would be nice to know what I am up against and why it is doing what it is.
As far as I know, about 1\8" actually sticks out inside the block.
It could have swollen up. The idea with the vice grip is a good one. Worst case is taking the pan off and driving it out from the bottom, but I have not had to do that.
Yes we used an old wire connector, but that does not sound like it will work. When I pry, it is against the tab with the bolt hole while pulling the other side to keep it straight.
You cannot push it back into. The sensor reads off a reluctor wheel on the back of the crankshaft.
This picture shows a tube in the block at the 10:00 that is the tube the crank sensor is in . This is looking down at the back of the block.
No, but is shows how close this gets to the back of the crank. Pushing the sensor is in not an option unless you remove the crankshaft.
Ok. I need to find a magic wand to hold in one hand and a bible in the other, am I understanding this right?
So my only option right now is to grab it as safely as I can, pry it as safe as I can, then lube the heck out of it and hope to god it doesn't break?
I am not sure what to tell you. Did you push it back down? There is an oring down lower and I have seen where there is debris caught between and I suspect that is why it will not move. I wish I could wave the magic wand but..........
