Converter wont push up to flywheel completely?

[Steve]

I just put the the new motor in my WE4 and I went to bolt the converter to the flywheel and I noticed there is a .045-.050 gap between the converter and flywheel. If I install the bolts the converter will easily pull up to the flywheel but if I remove the bolts it goes right back to the .045-.050 gap. The converter spins free when unbolted so I don't think the hub is tight so what else could be holding it back? I have a eagle crank, with a JW flywheel and a Vigilnate converter. I just got the converter back from PI and the crank and flywheel are new so everything should be good to go. Could it be the flywheel to crank bolt heads hitting the converter in the recess of the converter? Thanks

unless you are instaling a stock converter you will need to shim using washers, spacers etc. between the flywheel and the converter tabs

youll need to push the converter back against trans then measure gap and pull converter foward .125" and no more than .250" (i think thats the right pull distance ) then shim the space .

Hi,
Is this that important? After all, it is called a flex plate. I wouldn't sweat a few thousands. I could be wrong, so talk to me, guys.

it's that important

pulling the converter too far forward cuts down the contact area of the pump notches ,
pulling it tight to the flex plate will put strain on the plate and the converter face
also if the converter hub doesnt freely slide into the crank recess it can lead to damaged thrust bearing surfaces as the converter presses forward that the flex plate would otherwise be absorbing

If your converter has been fully seated in the tranny(snapped in as far as it will go), which is VERY important: you're well under the need for shimming. The Vigilante instructions call for 1/16" to 1/8" spacing between the converter and flexplate . Actually- if your measurements are correct: you're under what Precision asks for(.0625 min). Again- be CERTAIN your converter is fully engaged in the tranny. Your new flexplate is thicker than the stocker, which would account for the tighter fit(probably).
