Topic tags/keywords: contractor saw delta 34-410 trunnions cast iron table saw troubleshoot

Hi, this is my first post and I’m hoping to find some answers. I recently bought a delta 34-410 contractors saw that appeared to be in decent shape. I should also add this is my first cast iron saw, up until now I’ve had portable saws so the parts and mechanics are new to me. I Tested it and it seemed fine. Once i got it home and started cleaning it up I realized the whole trunnion assembly had play both vertically and laterally (vertical in the trunnion brackets, lateral due to gaps between the worm gear and trunnion rack.) The trunnions and gears don’t appear to be THAT worn out and the height adjustment has the same gaps but no play so I’m wondering if maybe the tie rods play a part in fixing the problem or maybe this is normal and the assembly’s weight is supposed to hold it in place. I just get a little rattle when the blade is slowing down and starting up. I don’t hear much while its running at full speed and got clean square cuts on a 2×4 I tested. Any information would be appreciated.

Thanks,
Riley adams

P.s.-just notice the stop block at the end of the trunnion rack is snapped off. Does this cancel the play at 90 degrees?

When the locking knobs on both tilt and height are loose, there will be a bunch of play.
The mechanism is really basic, the locking knobs should solidly lock the movements, if not, something may be missing.

Have your say...
