So today was the first time I have actually got to cut on my refurbished Rockwell 34-440. I went and bought a new 40T Diablo blade.I had some 3/4 inch Oak. When I ran it through the saw bogged down and completly stopped. It never tripped the motor either. I double checked the blade alignment, the fence alignment to the blade and both are as perfect as I can get. It is hooked straight into a wall outlet with no extension cord. The new pullies are in line and the link belt is tight. I even put the old v belt onto it for a second cut and it bogged down with that too. I took a chunk of scrap 2×4 and ran it through and it caused the saw to bog down as well. Any thoughts or ideas are greatly appreciated

Can you confirm that the belt is not slipping? My Unisaw has three belts between the motor and arbor. These have been replaced with link-belts and on the rare occasion I stall the blade, the motor (3HP) is still spinning, but the belts are slipping. Same thing, no breaker tripping etc.

Alternatively, you did see that you have the blade installed so it spins in the right direction? Don’t take offense! I’ve goofed up this way before and I am embarrassed that I completed several cuts with the associated difficulty before realizing my brain fart.

How are you checking your fence alignment? If it’s heeled in, even a little, it can bind the blade. You can verify by moving the fence to the other side of the blade and see if it does the same thing. If it cuts without bogging with the fence on the opposite side, you need to readjust your fence.

Does it bog on crosscuts as well, or only rip cuts?

Do you have any other blades you can try just to rule out that there might be a problem with the Diablo?

Are the pulleys the same diameter as what was on there?

That kinda sounds like the saw is wired for 240V instead of 120V and while it will work, the power would be half at best from where it should be.

Either like yeti said or the running capacitor is due for a change. I had one go bad in my drill press and it was the same symptoms… The 3/4 HP of the drill would stall on a 1/8th bit in pine :)

Provided it isn’t a slipping belt or loose blade, it could be any number of things – Wired wrong, bad cap, motor end bell put on slightly out of alignment causing bearings to bind, centrifugal switch sticking, binding or misaligned arbor bearings, loose wiring connection, etc… “Bogging down” doesn’t really help pinpoint it much.

Thanks for all the feedback. Belt is not slipping, the whole motor stalls out or stops while cutting.

Pullies are exact size I pulled off of it before replacing

So I listened to Yeti and decided to check on the wiring. (I didn’t have much confidence in it being the problem because I didn’t touch any of the wiring during disassembly.) The guy I bought it from used this saw up to the day I bought it following the diagram on the motor I pulled all wiring out and rewired. Low and behold he had it wired wrong. Rewired it up put the cap back on and the thing slices through wood like a hot knife through butter.

Hokie thanks for the tip. Well definatly be using that in the future. I tried it here but it was all a problem.

Thank you all for the help. Every answer I get to all my questions is another tool I can put in my perverbiabl tool belt to use later

That was an easy fix. All’s well that ends well!
