Thanks!
It says "Rockwell/Delta" does on the metal strip running under the brade raising/tilting dial. Everywhere else it says "Rockwell" Pittsburgh, PA.
Serial # EB-4410, Model 34-300
I called Delta, but they are closed for the weekend.
Ahhh! Ya didn't mention that.
1968 born on date per the serial number.
As they should be.
UA100
I went to the local Woodcraft store, and checked it out. It turns out the older Rockwell/Delta's have a heavier trunion bolt, so the Delta PALS won't work. However, the Craftsman version has the right size bolts, so I'll give that a try.
BTW Woodcraft is having a special 10% sale coming up (Feb 24th?). I asked the exact date, and they said it was coming up, but for me the owner said he'd give it to me starting today. So I spent money.
See my other posting for info on the Kreg Miter Gauge
My Rockwell/Delta 34-300 10" Tilting Arbor saw (made in 1968, SN# EB-44410) has recently become louder. I decided to give it a tune up, and check things out.
For reference, the parts diagram can be seen here:
My saw has a small toothed belt going from the motor to the arbor above it. When I run the saw without the belt, it whines. When I attach the belt to the arbor bearing, there is a louder rougher noise.
So I think the Arbor Bearing is shot (Part 175 or 176 in the diagram).
I can remove the motor. Do I just get a wooden rod and hit the backside of the bearing (I see a circular depression on the motor mount side.) In other words, do I push it out, or pull it out?
I have some run-out when measuring the Arbor Pulley Flange. It's seen a lot of action, with dings, etc. I sanded the surface a little, and that helped. But I'm still getting 0.005" run-out.
I'm considering holding some fine sandpaper against it while it's running. Perhaps the bearing is affecting this, and I should hold off until I get that resolved.
I'll call up Delta Monday. Anything else I can try? I still have to locate a machine shop to true the Arbor Pulley Flange.
Ahhhh. the other side benefit of getting your CS aligned...

Well, after talking to tech support, I tried disconnecting the belt from the arbor, and attached a blade, and spun it. A definite rattling sound. Dang. And I just bought $300+ worth of upgrades for my old saw. (Kreg Miter, DP FaskTrak, stops, etc.)
It's got a nice cast iron top w/wings, motor. Sniff. I'm gonna have to dig a big hole.

Why can't you just replace bearings?
I asked if the bearing could be replaced. The tech support said the bearing is part of the arbor. They made a "lifetime supply" of this special part which ran out in mid-1980's.
Ok, thought it might be worth asking--sometimes you're stuck w/ a bad design... :(
I haven't given up yet. Delta gave me phone numbers of independants that might have parts. I will also try to remove the arbor and see if some part can be replaced. But I'm preparing emotionally for the worst.
Hey an extra, nice flat top is always useful for glue ups. Perhaps it could be converted into one of those homemade drum sanders others have been posting about recently. Router table?
When life gives you lemons....

From the diagram I can't tell what would be totally unrepairable if it is just a bearing failure...what part was it that Delta thought you needed that is no longer available? Or were they going to sell the whole armature assembly?
Might have to get some help pressing the bearing off the shaft but assuming one could find an equivalent bearing (good/bad probability depending on how old and unique it really was) I'd think it at least possible as long as the shafts are still ok. At the point of rebuilding the armature shaft the cost may become prohibitive...
The Arbor and bearing is a single part number. And I assume a single part. I'm going to try to dissassemble it this weekend.
I betcha if you take it to a machine shop they can press it apart in about 2 minutes.
That's what I was going to suggest after looking at the drawing again...
May need to take the motor bell housing as well as it appears the shaft is pressed into it as well as near as I can tell...
Overall, looks like it should be easy enough as long as the bearings aren't too exotic...but even there, undoubtedly the machine shop could fix that if mandatory.
I may have do. I wasn't able to remove it from the housing.
Not surprised...that's probably "the part" :(
What shape are the bearings in? If they're not turning on the shaft, you should probably be ok.
Good luck, let us know how it comes out...
When I turn them by hand with nothing on the arbor, they seem okay. But when I attach a blade and turn them (disconnecting the belt) there is a rattling noise.
When the motor is attached, and on, the noise is really loud and ragged. It no longer whines. It growls.
Anyhow - I'm considering a new saw. Perhaps someone near Albany NY wants the old Rockwell/Delta 34-300 for parts, or willing to try to fix it. It has a nice cast iron table w/extensions, and the rip fence has two clamps front and back. Best offer gets it at the end of the week, and I will gladly accept "free and you haul it away" as a valid offer.
SWMBO says I can't have two table saws. While another glue-up surface is nice, space is a big issue in the cellar of my 150-year-old farmhouse.
The old one was $200 used, and lasted 20 years with occasional use. It's been a good friend...
I have one story for the eulogy. We have a wet basement, and the sump pump was working overtime on the spring thaw. At the time I have the hose going out the window, but by contracting and expanding all the time, the hose wore a hole, which leaked, and the basement was filling up.
Well, I come downstairs to discover the inches of ice water. But the worst part was the hose has twisted, and a stream of water was arching in the air 6 feet. I slowly traced the arc of water with horror, where - you guessed it - it landed right in the middle of the cast iron surface of my table saw. The water has been hitting the surface for hours. I said many many MANY bad words.
Anyhow - I stripped the table apart and cleaned it up real nice. But that was years ago.
Dang. I lost a pet cat last month, and I had to put him down. And now is time for the saw. Do they have Hallmark cards for putting down power tools? They should.

Before you actually put it down (unless, of course, it's the reason you've been hoping for :) ), I'd at least get a machine/bearing shop to evaluate it for what it would cost to press a new bearing.
