I ordered a ACT converter from Probuilt and part of the tabs on the converter where the bolts go through sit on the ring gear of the flex plate. THe ring gear does not sit flus with the mounting pads on the flywheel.....Isnt this bad or is it normal. I dont wanna screw this up. Its a brand new flexplate from Jegs and new ACT 9.5in converter. Do I need to grind the tabs a little or what?Thanks!!!

 

They usually don't... that's the exact reason why it's called a "flex" plate. It's not the converter that's off, it's that piece of sheet metal in front of it. Just bolt it up, it will "flex" itself to right where it needs to go.

 

Should I put maybe a washer in there like an 1/8 of an inch to help engage the pump better like other post have said to do?
Thanks!!!

 

Becareful.. when I was installing my ACT 9.5" 2400 in my Probuilt tranny Dana specificly mentioned that the TQ had to be spaced properly from the flexplate. I'm using the stock flexplate btw.

Unlike my stock TQ, the ACT TQ didnt have any threads or pads to screw the stock bolts into. Dana had mentioned this to me I think when I bought it. Anyway, I called Dana to refresh my memory and he mentioned that I would need to get some hardened washers, double them up so they measure .100 to .125 of inch. Basically an 1/8" thick when doubled. The trick was to find a good parts store that carried hardened washers. I called my parts guy, and wasnt able to find any there. I ended up buying a bag of 75 hardened washers from Orchard Supply Hardware. Using a micrometer, I measured out about a dozen before I found three sets that mic'ed out the same. To help with the install, I super glued the washers together using a small amount of glue when doubling them.

The reason you want to make sure its spaced properly according to Dana(please correct me if I'm wrong here) is that if the spacing is off you'll ruin your front pump from the wobble. Good luck and I would give Dana a call in case I missed something.

 

I did EXACTLY the same thing as flotsamm. worked for me!

 

ooops, i just reread your message. it is quite disconcerting that your torque converter is resting against the "ring gear" part of the flywheel. Is your flywheel flush on the opposite side and thus mounted backwards? maybe the flywheel diameter is wrong?

i don't like the sounds of it. call dana, he'll know!!!

 

First, you need some clearence between the torque converter and the flex plate (before you bolt it up), the clearence should be .090-.125. If the torque converter is hitting the outside edge (ring gear) of the flex plate, you will need to grind the torque converter tabs slightly to solve this. Make sure the flex plate is installed correctly, before you do any of the above mods. If the torque converter has (for example) .160 clearence between the flex plate and the torque converter, you would need to reduce it .035-.070, to achieve the desired clearence. Whatever flat washer you decide to use to reduce clearence to get the correct settings, all three washers must be the exactly the same in thickness. I hope I am making myself clear here.

 

I dont understand why the torque converter mounting tabs hit the ring gear????? It does so on the stock flexplate as well.....WTF????

 

Call me tomorrow after 11:30 PST at 800 7763288, and lets see what we can or need to do.

 

neither of the converters should hit the flexplate. Maybe you have it installed backwards? The plate has recesses stamped in it so that the plate part of the wheel sits flush with the ring gear. If it's backwards, it will be offest the wrong way.

 

whoops, meant to say shouldn't hit the ring gear. bottom line is that the ring gear and the plate should be flush (or the gear might be slightly offset towards the front)at those stamped points, so that the converter tabs only touch on the stamped areas.

 

SO what should I do??? Just grind the tabs and be done with it? How do I know if I have the right converter. It looks rusty in spots and looks like its been painted before cus you can see where the paint underneath is still chiped. Man $600 seems to be alot for a used converter...its supposed to be new????

 

dude. pick up the phone and call dana at probuilt. he's the one who can solve your problems. when i put my 700r4 and ACT in, i ran into a few oddities too, but dana took care of EVERYTHING.

 

What kind of problems did you have?

 

You are right $600.00 is a lot for used A.C.T. torque converter, as I said earlier, call me after 11:30 PST at 800 7763288 M-S, and lets see what we can or need to do, or call me tomorrow (sunday) after 1pm PST.

 

I will be giving you al call tomorrow arounf 1 thanks for your concerns....
