Hi all. As I described in another thread I some time ago purchased a new Grizzly G0691 tablesaw which came with some problems. After much too and fro, Grizzly finally sent me out the replacement part, which I’ve been trying to install today. But I’ve got stuck, Grizzly is closed until Monday, and I’m wondering if anyone has a suggestion.

The replacement part is a new Geared Bearing Housing>

Today I removed saw’s rails, tabletop a few other bits and pieces and finally the old housing:

Now I am supposed to transfer the riving knife components from the old assembly to the new one. The components fit over the two pins you see in the top picture on the new housing.

The problem is that I don’t see how to remove the riving knife components (ie the long “bull gear” and the shorter plastic “orientation bar”) from the old assembly, because the Blade Arbor is in the way.


The pins are much longer than the clearance between the “orientation bar” and the back of the blade arbor and the orientation bar is tight to them. I don’t want to bend the pins or break the plastic orientation bar.

Grizzly’s instructions were just:
Remove the remaining riving knife components from the original Geared Bearing Housing and replace onto the new part

Am I missing something, being stupid or does the Blade Arbor have to come off to detach the riving knife components??

Any suggestions appreciated.

The small piece under the lip is removed first & you should have room to lift the arm up & out. A view from the end of the arbor would help.

But the small piece has the pins running all the way through it so you can only lift it straight up, in which case it hits the arbor. Heres views from the end of the arbor:

Do you have access to the pins from the other side, so you could remove them? They are just spring pins and should be removable.

Cheers,

Good question, I had to go check. One of the pins is pretty accessible but the other is in a narrow area between the arbor pulley and the housing:

Not sure how I’d get that one out.

On the new assembly of course the pins are exposed on the front side, I guess I could pull out the pins with pliers and tap them back in after the piece is inserted under the arbor…... not sure if that would damage the pins…?

Looks like you can easily punch the pins through on the old part… they will pop out the back. And you can probably get the small piece on the new part without messing with them. Goofy design.

Cheers,
Brad

That wont hurt the new pins. On the old one try and drive the pins in further with a punch and see if they will allow the orientation bar to slide out of the way for the main bar to come off the pins.

Right, knock them thru from the front to the back. Back at it in the am. Thanks!
