Hit a roadblock on a teardown of an old BT3000

[adambsullivan]

How do I remove this piece?

I'm trying to do a full disassembly/cleaning of very dirty BT3000 I recently acquired. I want to clean and lubricate the shims behind this plate but I can't get it off. I took out all the fasteners I can see and now I can wiggle it a tiny bit but can't get it off.

I found a YouTube video where a guy hits the arbor a few times with a mallet and it all comes loose but that is not working for me. (It won't let me share a link here but the video is titled "BT3000 Shim Replacement" and the relevant part starts around 7:16)

What am I missing? Any tips for getting it off?

Also open to any other tips on restoring the machine. Thanks!

Maybe four screws? Never had mine apart

here are two hi-res scans from the BT3000 manual for exploded diagram and parts list, if that helps.

Maybe 2 screws, 85, hold the guide holder 80 to the motor 1 as shown.

Your picture looks like you have already removed the two screws on the bearing plate and the four screws that hold the guide holder to the motor assy. You can use a set of pry bars to carefully pry it off the bearing. If the does not work try a 16 ounce dead blow soft face hammer on the arbor. Third option, and really this is getting desperate, get longer cap screws that match the shim adjustment screws and use turn the bracket into a puller, an eighth turn on each at a time.

All that said, tapping the arbor with a hammer could just make things worse since the motor bracket will pivot on the elevation screw. tapping will try to force the parts to separate in an arc.If you have this whole assembly out of the saw and have removed the elevation screw then you should be able to use direct pressure on the arbor to separate the parts. If it is removed, do you have access to a hydraulic press?

In the early days I had to change or replace my shims a number of times until I installed Norm's shim supports. search for my shim article in our article section. Anyway mine always came apart with out much effort.

By the way, Welcome to BT3Central, err I mean SawdustZone.org

I has been 30+ years since I had to do this, and long before I found this site, but in the four small holes there were set screws in mine to adjust the shim tension. I removed those, and used longer machine screws of the same thread and progressively tightened them to separate that plate from the motor. I only needed to do that the first time I replaced my shims until I eventually replaced them with the BT3100 version.

This worked. Thank you, twistsol!

When I was getting ready to leave Japan, I disassembled my BT3000 completely and had no problem with the disassembly, but I just cannot remember that part except that I know I did. And I had no problem putting it back together. My son-in-law now has it. I would have commented on it earlier but as I mentioned, my memory is fuzzy on what I did. That was 16+ years ago for disassembly and 15 years ago for reassembly.

Jim great reference links.

Well, I said my memory was off: https://www.sawdustzone.org/articles...im-replacement
I must have given my Bt3000 to my son in law sometime in 2015 after using the dado. (I kept the BT3100 for myself)

I was sure I took that section apart before the move in 2010, but apparently did not. Since reading that, I only remember that I added the new shims before giving it to my son in law, but thought I did that when I re-assembled it in 2011 - back here.
