Milwaukee Circular Saw: How do I replace the spindle gear on Milwaukee cordless circular saw?

Mon, 22 Dec 2025 09:44:29 -0700

I was given a Milwaukee 18V cordless circular saw, Model 6310-20, Serial 057A----.
I took the saw apart and found a number of broken teeth on the spindle gear. The gear at the end of the armature shaft is in good condition.
The Milwaukee parts diagram shows that the gear and spindle shaft are separate parts.
There is no circlip holding the gear on to the spindle shaft or woodruff key keying the gear to the shaft.
Is the old gear just pressed off of the spindle shaft and the new gear pressed on?

Craftsman 315.108220: How to lock the blade shaft on a Craftsman 315.108220 circular saw?

Fri, 04 Apr 2025 09:42:18 -0700

Does anyone know whether there is a “brake” on the driven saw blade shaft of this model so you can unscrew the blade bolt? If not can you suggest how I can lock the shaft and remove the blade bolt? The blade is loose and freely rotates on the shaft but it is impossible to remove the blade bolt because the blade shaft and the armature turn. I seek suggestions how I can lock the shaft and thus remove the blade bolt. Because the saw blade can not be removed, I can’t fully disassemble the saw and thus gain access to the gear case where I could lock the shaft..

Black Decker Circular Saw: Saw Stopped Suddenly, won't start again

Wed, 04 Dec 2024 14:47:23 -0700

I have a Black and Decker Saw Force 300. While using it it got a little sideways on a board and stopped. Now it doesn't turn on at all. I tried looking for a breaker in the circuit that might have tripped, but can't find anything.

I have no clue as to how to get it working again. Would like to, as it's a perfectly good saw otherwise.
