I posted on here awhile back about my new Delta table saw. The trunnion is about 3/16″ off from the front of the blade to the back. I called the company and they send me supposedly better instructions.
I loosened all four bolts and tried to adjust the trunnion. I can’t get it to improved by only half way. I tried as hard as I could and I still can’t get it. Has anyone else had this problem and how did they fix it? I can’t return it because it would be a pain in the butt.

"The trunnion is about 3/16ths off from the front of the blade to the back."
Are you saying that when you checked whether the miter slot was parallel to the blade, the blade was skewed front to back by 3/16ths? If so, what kind of saw do you have...a contractor's saw or a cabinet saw(unisaw)?
On a cabinet saw you loosen up the bolts holding the table to the cabinet and then reposition the table, slowly tightening down each bolt . Tighten bolts in a diagonal fashion...same as when tightening lug nuts on a automobile tire. The table can and usually does want to move when tightening...this is a slow , tedious process. I've been fortunate never to have to adjust my Powermatic 66.
If you have a contractor's saw, then the trunion itself gets unbolted to the table and repositioned. I've never worked on a contractor's saw.
If your table top is slightly out of level, use metal shims between top and cabinet to bring up to flat. Beverage cans are good material for cutting out shims.
You may want to post over at KNOTS as those guys are all experienced cabinet makers and probably run into this sort of thing more often and can probably give you a better tried & true answer.

You can use a pipe or bar clamp to persuade the trunnions to move. Loosen the bolts, gently snug them up, and then make the adjustments needed with the clamp.
Also, its a good idea to upgrade the bolts to a better quality, say grade 6 or 8. They won't give as much when you tighten them. And when you do tighten the bolts, do it gradually, so you don't shift anything.
man that sucks, I would be having the rep replace it at their cost!!!
You need a jack screw system, so you can push things to where you need them.
I installed these, on my Delta Contractors saw, and both brothers Craftsmans.
They make it far easier to get things right.

You should be able to slacken off the bolts and go either side of where the setting should be. If your running out of travel in the slots and nothing else is in the way then there is a problem the factory should fix.
Get some help and turn the saw over so you can see whats wrong. Maybe a casting "lump" is in the way.
