I just put a pro yank in and have a 1/4 gap between the converter and flexplate what should i do?

 

Put a washer between the flexplate and converter. Make sure all three are the same thickness.

your question has already been answered... why would you bump this thread?

 

to see if anyone else has anything different to say about it

 

There ya go.

 

If you mean there is a gap when installed without bolting it up you should be able to mate the flexplate and converter with the bolts.

 

Ideally you should have no more than 3/16" between the flexplate and the converter pads when the converter is fully seated into the pump.

The advice about using a washer at each mounting pad is the correct advice.

does the diameter of the washer make any difference? i would think this may throw the flexplate off balance a little bit...

 

Ok well, you have only two other options. Pull the trans, and put a shim behind the flexplate, or have the converter cut open, spaced, and re-welded. It isn't that hard to figure out.

 

Make sure though that the washers your going to use are grade 8 flat washers.

 

Ideal clearance here is .80" - .125". Bring it down by adding a machined washer at each corner. The three shims that you will need to reduce this clearance "must" be "identical" in thickness, to bring the torque converter up evenly. By doing this you are getting the maximum contact area between the torque converter hub and the rotor in the front pump.

 

That's about the most invasive way to go about it. Way too much work, it is not necessary to remove the transmission to shim the converter. And it is just not practical to go through the effort of having the converter reworked...

Just not worth the tie and trouble for all that... place washers between the converter and flexplate and it'll be just fine. I have very fast trailer cars making well over 2,000 h/p running similar shims with zero issues. The key is to locktite the bolts and torque the properly once the proper spacing is achieved.

+1 Not to mention that shimming the flywheel to crank might cause starter/ring gear issues. Sounds like a lot of shims to me. Gil I think Todd was being sarcastic. I to have used washers for years without an issue. Vince

 

You must have missed my first post.
