Chrysler Repair: Loosening Crankshaft Damper/Pulley Bolt: 2.5 V-6, crankshaft damper pulley, pulley bolt


Question
Hi Roland,
     
       I'm trying to remove the crankshaft/damper pulley on my 1998 Chrysler Cirrus 2.5L V6 (pre-timing belt removal). The Haynes manual simply says to wedge the pulley itself with a bar/screwdriver and then break it free with a 1/2 breaker bar.
I'm happy to report that doesn't even come close to working.

I've tried every different way I could think of to either hold it or wedge it but it keeps bending tools, snapping tools and eventually turning which stops the main bolt from breaking.

Is there a special tool Chrysler uses to hold their pulleys in place on the 2.5L?
There seems to be a couple for other size engines, including the 2.7L.  I'm not sure if that would fit.

I'm hoping your shop manuals mention a Special Tool or part #.

Thanks for any help,  
             Wes  

Answer
Hi Wes,
Unfortunately no tool is mentioned. The bolt is conventional right hand thread but it was torqued originally to 134 foot-pounds if done to spec. I have one idea: check to see if there is an inspection plate at the other end of the engine which would give you access to the flex plate and its teeth (with which the starter motor bendix gear meshes), and see if you can jamb it by inserting a bar into a space between two teeth which would then be wedged at the bell housing edge of the opening, or you could try removing the starter motor to gain that same access to the teeth.
An 'off the wall' idea, and maybe not too safe would be to use a long enough breaker bar on the socket that it touches the ground and then try just energizing briefly on the starter motor (tweak it) while a helper holds the breaker bar wedged against the ground to see if the starter might generate enough torque to break the grip of the bolt in the crankshaft. I believe the motor turns clockwise so it should unscrew the bolt.
Another possibility is to try a conventional removal approach but with the engine warmed up to operating temperature.
Please let me know if either of these works for you.

PS: There are some chain-based wrenches that you might try that when  the chain is wrapped around the pulley might grasp its surface with sufficient tightness to hold it in place.
