Howdy everyone. I'm going to be jerking the transmission to replace the rear main sometime in the near future, as some of my earlier threads indicated. Since I am going to get an upgraded torque converter and the 1st gen flexplate is weak anyway, I am going to upgrade. First, I found a flexplate from a 99 my Dodge with the 24 valve. Will this work? Also, what are the torque specs on the flexplate bolts, and what kind of locktite should I use? I will appreciate any advise. Thanks!

 

I would just spend the $100 for a brand new one from cummins, UNLESS you know EVERYTHING the truck has beed though

 

The flexplate is no place to save a few bucks with a used one. It wouldn't seem like much of a bargain if you had to drop the trans again.

 

What is the part number for the Cummins flexplate? And, again, will a 99 model 24 valve flexplate work? Also, what are the torque specs for the bolts?

 

from the FAQ section: I just orded that flex plate from Cummins myself, by the time I paid taxes and shipping it was just under $130 to my door.

I'm not sure on the torque specs... actually, i'd like to know those myself...

 

I sure wouldn't use a used one.

 

Just curious here, whats so bad about a used one? Is there a chance that it is out of balance, or cracked, or something like that?

BTW, thanks for the replys. I am going to check out a new flexplate as soon as I get to a Cummins dealership.

 

As far as you first question, you don't want a used one because, Yes, Yes, and Yes.

Just get the one through Cummins.

A used one for a new truck could spell bad news there could be stress fractures in it that you can't see. The lock up converters put alot more stress on the flex plate.

 

For a 2003, torque the flex to crank bolts to 55 ft/lb and the flex to TC should be 270 in/lb. This is per a 2003 Chrysler service manual.
