Flywheel installation on new remanufactured 2.7 engine
 

I have a new remanufactured 2.7 engine for a 02 chrysler sebring convertible lxi. Is there a alignment that needs to be followed for reinstalling the flywheel.

No. Per the shop manual, bolt it to the crankshaft and use a thread locker on the bolts. Tighten to 70 ft. lbs.

Thanks, that is what I thought. But if I were removing it and putting back on the same engine I would have marked it so to put back exactly the same.

The flywheel (flex plate) doesn't care where it is as long as it's bolted in place. The crankshaft position sensor reads directly off the crankshaft, not the flywheel.

mehhh the crank sensor on the 2.7 uses the fly wheel tone wheel for the reference to where it is in the rotation. As for marking where it goes if im not mistaken it will only go on one way the bolt holes will not align up in any other way but one way. and a dowel pin for that as well

On the older (pre-2004) models, the crank shaft position sensor reads notches and gaps in the crankshaft itself. At least, per my shop manual.

2004 up is notches on the crank itself 1998 to 03 late 04 are on the flywheel. that was SBEC computer and 2004 up is NGC computers. this is why people have issues when they swap newer engine with older cars the fly wheel and the cam tone wheel are setup for newer computer systems.

My 2001 shop manual shows notches on the crank. I don't have a 2004 manual.

You are both right, just different engines. The crankshaft position sensor pulses off of the crankshaft for the 2.4l 4-banger, and pulses off of the tone wheel on the torque converter drive plate for the 2.7l v6.

For the 2.7l, the position of the flex plate/ flywheel to the to the crank shaft is keyed and can only be installed in a specific position.

I am referencing my 2004 Sebring FSM.
