Have a question about my crankshaft sensor plate!

Alright so i'm curious to know if that plate is supposed to move while turning the crank? and if not how do i get it to stop spinning with the crank? I'm currently in the process of a timing belt change and was curious to know if this was normal or not? Please help need to get the car back up and running ASAP so any help would be greatly appreciated!!

Behind the timing belt pulley and the crank is where the plate goes, Im guessing you have it between the crank pulley and tbelt pulley?

It's in the right spot I believe it's behind the furthest one back I'll have to double check, also how can I get the bolt with the 1/2" drive square on it off with the belts off already? I'll take a picture tomorrow when I get home from work and have you guys check it out and tell me what you think!

It is supposed to spin with the crank. The metal plate is actually a trigger wheel that sends a signal through the crank sensor which is stationary. The trigger wheel/plate rotates through the actual crank sensor itself.

The crank bolt is a ***** to get off....You will need a really big breaker bar or a powerful air gun to remove it.

Sorry for the crude drawing LOL but here it is.

The red "x" is the cranks sensor. The red arrow is pointing to the trigger wheel.

As you can see, the balance shaft belt is behind the trigger wheel.

Are you following the Timing Belt How-To? It is a great help and what I used for all my timing belt changes.

Here it is just in case you have not seen this yet.

HOW TO: Timing Belt, Balancer Shaft Belt, and Accessory Belt Replacement

You don't need to remove the crank sprocket or wheel to remove the balance shaft belt. You can remove the crank sensor, and slide the BS belt out around the wheel. Just turn with a 1/2" breaker bar and slowly pull the belt out thru the position of the wheel with less diameter. Install the new belt in reverse.

Alright so here's another question does the trigger plate have to line up with the marks? Mine doesn't when I set everything to TDC is this going to be a problem?

Please review/read the HOW TO I posted. Great pics to show you what I'm talking about.

The trigger wheel only goes on one way. There is a guide pin, if that's what it's called. There is also a notch on the wheel that is used to set the crank to TDC. You have to make sure the Oil Pump Sprocket is set to TDC as well BEFORE installing the new balance shaft belt and new timing belt.
