Hello,

Lats friday I was installing my new riser block for my Grizzly G0555 Anniversary Edition band saw. My saw doesn’t have much use unfortunately and is about 2 years old. I got to the point where i put the blade on and beginning to turn the wheels to see where i was at with the tracking. On first half turn all of a sudden i hear a ting and what ended up being a bolt or set screw or something flew off and had sheared off.

I called Grizzly to see if i could get some information or to see if by chance this thing might be covered in some way. It was not it seemed. While on the call the gentleman didn’t seem to know much about the saw i felt but was helpful but couldn’t tell what the bolts were used for or how it was setup on the machine. He seemed to be looking at the same diagram i was in the manual. He asked eventually for me to take the other screw out to see what we were up against since there were 2 of them. I loosened the nuts on the bolt, inserted the allen wrench and snap there went the other one too. I put very little force on it.

Does anyone have any ideas how to extract these screws? Any ideas what they are used for by chance? I am certain it has something to do with the tracking. I am hoping to get them removed as easily as possible without having to invest more into the machine.

Here is a picture of the first screw the flew out and you will see the ohter behind it prior to it breaking.

Thanks for the assistance.

I see the image is rotated for some reason. Rotate counter clockwise for correct orientation.

I don’t have that saw so I just looked at the parts diagram for G0555 out of curiosity. The diagram doesn’t seem to match your picture. I assume this is the upper wheel sliding bracket that adjusts the tension and tracking? If not the rest of this won’t make any sense.
Did you buy this saw new from Grizzly or was it used? Seems like there should be a knob on the top (left in your rotated image) for adjusting the tension. It sort of looks to me that someone changed the tension adjustment knob to a couple of jam nuts? First I would back off the tension and remove the blade, You might want to even back off the tension completely just to make sure you don’t hurt yourself. You might have to remove the upper wheel to see if there is access to those 2 bolts from the other side behind the wheel.

Just spitballing like the Grizzly guy apparently was but maybe the differences compared to the diagram are what had him stumped as well.

I see part number 30A-1 on the diagram I looked up. It looks like grizzly uses a 2 part shaft for the tilt mechanism as opposed to a 1 piece shaft like my old Rockwell. Perhaps this set screw and its friend are there to keep the shafts from falling out. If you get the broken screws out it will be interesting to see if the shaft i’m thinking of has a groove for the screw so the screw acts like a pin or scarring where the screw dug in. Or perhaps grizzly thinks that once you set your tracking you need to lock it down withing and inch of its life and those screws are answer to a question nobody asked.

Suggest you call Grizzly back, and discuss the revisions to PN P0555030 bracket in the parts list?

There are obvious differences between your image and the current G0555 parts list online, which calls out P0555030A as UPPER WHEEL SLIDING BRACKET V2.07.07.
The current version on has ONE set screw in it:
https://www.grizzly.com/parts/Grizzly-UPPER-WHEEL-SLIDING-BRACKET-V2-07-07/P0555030

Have owned a couple different 14” band saws, and most are very similar. Surfed thru Delta, Ridgid, Jet parts lists looking for examples like yours, but they all look like current Grizzly bracket:
https://www.ereplacementparts.com/bracketupper-wheel-sliding-p-446061.html
https://www.ereplacementparts.com/sliding-bracket-p-84683.html
etc

It appears that your sliding tension bracket has 2 mounting bolts for holding the upper wheel pivot (item #35-3) in place on inside? That hinge holds the upper wheel shaft on it. Will need to remove the upper wheel to get to the hinge and figure out what is broken. Wheel axle nut is usually not hard to remove, as you have a large wheel to hold while you turn the nut. Wheel will slide off the axle shaft and expose the other side of upper bracket, so you can see what happened.
My guess is you will find the pivot is no longer attached to anything if both bolts are broken, the upper wheel might even fall off when you open door. :-(

Best Luck.

Not entirely sure what they are used for as the knob (shown in your picture) should be for that. To get the broken bolts out, use an extractor set, something like this:

https://www.amazon.com/Irwin-Tools-Hanson-Extractor-11135ZR/dp/B000EEX644/ref=sr_1_3?keywords=irwin+screw+extractor+set&qid=1553434275&s=gateway&sr=8-3

You use a left handed twist bit to drill a hole into the bolt and then use a spiral screw extractor on a ratchet to remove the stuck bolt.

Good luck!

Apologies for the delayed response.

Thanks for all the suggestions.

This saw was purchased brand new about 2 years ago and hasn’t been used much to be honest so I am pretty frustrated this would break like this already.

Let me run by what I think is being suggested
1. I need to remove the remainder of those broken screws but what I am not clear on is if i should try to do this without taking it apart or not?
2. If I can’t do this i should take the top wheel off and see if i can see what is going on from that angle and continue disassembly as needed
3. I did buy a screw extractor prior to posting this. The screws are pretty small in diameter it seems and is different then what @Geeph posted. Will this work? (picture below) I bought them at the same place i bought replacement screws. It is a local shop that if you need something they likely have it sorta place. Especially if it is a bolt or screw for example.

Hoping the below works but I feel like i have one shot at this otherwise I am replacing that whole part

Does this seem about right?

After thinking about your issue further, went back to Grizzly site and found your actual manual:
https://cdn0.grizzly.com/manuals/g0555lanv_m.pdf

Page 61 shows the purpose of the screw you have broken. They are the Upper Wheel Lateral Adjustment screws.

In order to fix this will need to do some tear down-
Need to remove top wheel (1 axle nut) AND the upper sheet metal around the wheel (only 3 screws).
Once you reach the pivot assembly, you will see how those screws attached to the axle pivot arms. With both screws borked, the pivot arm will be loose when sheet metal is removed, so be ready? If you loosen bolt #131, can unscrew tension screw rod from the sliding bracket assembly, the entire sliding bracket can be removed. This will allow you to work on screw removal on bench, or maybe even use drill press to drill out or remove the screws.
Looking at the time factor for screw removal/repair .vs. replacement, might want to consider a new pivot bracket for $9, https://www.grizzly.com/parts/Grizzly-SHAFT-BRACKET/P0555LANV194
or
sliding bracket assembly for $21?
https://www.grizzly.com/parts/Grizzly-SLIDING-HOUSING-ASSY/P0555LANV030A

Best Luck.

Thanks again.

Any idea how to get the below pins out? There are pins it seems on either side but not sure how to remove that pin

One more thing. I am trying to drill into the screws to see about extracting them. They must be pretty hard steel as I am not making a dent. any tips on how to get hole in these to get them extracted?

If you have a center punch that can fit into the recess get a dimple in the middle. Will help you to keep the bit from wandering. Small cobalt drill bit may help as well. I have heard that the carbide tipped masonry bits sometimes work in hard steel when other bits will not, but I have not run into a situation to try that yet.

Start slow to get the bit set and not wandering then speed up. Don’t try to force the bit, you will just add extra heat.

A masonry bit. OK. i will give that a go too. Thanks again for the assistance.

Any idea how i get those pins out to release the shaft bracket from that housing?

Grizzly Tech service should have band saw expert to walk you through the pin removal.

Check with flashlight for the allen screw hiding down inside the outer threaded hole?
They are holding the pins in place. Might need a good tap in workbench to knock the pins loose.

If the pins are not loose after removing the set screws, then i’d guess your borked screw pieces may be preventing the pins from sliding out? Call Grizzly, but might need a new bracket assembly?

FWIW – Broken pivot brackets can easily happen if you get carried away with tilt adjustments. DAMHIK

Just a recommend from having dealt with numerous broken off bolts/studs: Get a left hand drill bit and try that first. The last thing you want is to have a broken off extractor (which is hardened steel), in a hole. They are next to impossible to drill out. Soak the area in your favorite solution, I use PB Blaster, and let it sit for a day or two. A bit of heat might help too, as the heat/cool cycle might loosen up any crusty crap in the threads. Center punch the stud/bolt, and slowly drill it with the drill motor in reverse. It’s easier to use a drill that doesn’t have a hand chuck, as they tend to loosen up in reverse.
