So, the other day I’m out n the shop minding my own business taking perfectly good lumber and turning it into kindling. When all of a sudden I had a thought of putting a 45 degree bevel on my kindling sticks so when I burned them in my fire they would burn at a 45 degree angle. Well, when I went to turn the bevel handle on the saw I noticed it was unusually difficult to rotate. I don’t bevel much so I’m sure I haven’t “worn” it out. The saw has a worm gear knob on the end of a shaft that stays engaged with the trunion gear. Now,I have noticed the two are no longer engaged. There is a gap between them and now the whole thing swings freely. Has anyone ever had this problem? I took it apart thinking the shaft had bent. I noticed the shaft is offset intentionally. I tried bending it and one way and then the other but cannot make it engage the trunion gear. BTW, Ridgid has discontinued this saw so there are no parts for it. I really love this saw, especially the granite top. The saw still runs fine but now I can’t stabilize the motor.

Oh and by the way. I was only joking about the fire burning on a 45 degree angle.

Is there a set screw in the worm gear that attaches to the crank shaft? If so, that could have sheared off.

On my 4512 on the lifting worm rod the C clip came off, allowing the shaft to back out. I don’t think you have this problem.
I looked at an exploded diagram of the 4511 at, and there was no obvious reason save that it looks like the only two places that angle worm rod is supported is at the knob area, and just below the trunion, actually part of the trunion.
One of those has to have moved to allow the shaft to drop, or possibly the shaft has come away from the knob assembly due to it loosening, and has dropped a bit.

Thanks for the replies.
I too downloaded the exploded view to try to figure it out. And I did. Seems the shaft that the holds the worm drive was not turning inside the Eccentric causing the eccentric to mis-align with the trunion gear. I removed the shaft from the saw and had to beat the shaft out of the eccentric. When I did I noticed a bad scar on the shaft. Obviously something had gotten in the eccentric and through time finally seized the shaft from rotating on the inside. Anyway, I made the necessary repairs to the shaft. Aligned the eccentric with the trunion gear and now all is well with the world.
Thanks again.
