General bandsaw 490 upper wheel removal
Hi,
I recently picked up an old General 490 bandsaw.
It’s overall in good shape but has sat for a while and is pretty old.
I wanted to remove the wheels to install new bearings and tires.
The upper wheel is held on with a nut which unscrewed fairly easily.
As far as I’m aware the wheel should then slide off but it seems stuck fast on it’s spindle/shaft. It spins freely but I can’t get it off the spindle.
Does anyone with a better knowledge of these machines than me know if it should slide off or if there’s another component holding it on that I’m not aware of?
A clip or retaining screw somewhere, or is it likely just stuck on with rust and dust and father time?
Would greatly appreciate any advice.
Many thanks,
Kerry

There is probably a set screw there. These are easily overlooked. Forcing it will do a lot of damage. I encountered this on an old Northfield, but I am not familiar with the General. Here is a link for the manual and parts breakdown, maybe P-7. It would be in the hub of the wheel securing it to an indent in the shaft

Thanks for the reply, much appreciated.
Unfortunately, P7 in the upper wheel assembly seems to be the screw that secures the pivoting pin in the pivoting arm. I just can't see anything there at all
Look for a square key holding the wheel to the shaft. There is usually a setscrew holding the square keystock. Use a mirror, it could be in the back of the wheel. (General observation, I do not have a General)
Ok, thanks, I'll check
Very likely that the wheel is a press fit on the shaft or what is called a light press fit. Yes, even with a bolt of nut on the end.
Safest way to get it off is once you are sure there isn't a set screw, use a wheel/gear puller. It should pull it right off. Even if it just stuck this is the safest way to get it off without damage. You can rent these at some of the chain auto part stores.
Thanks for that. I'll look into that
Did you have any luck with this? I'm actually dealing with the same issue on my General 590.
And if you find a set screw and remove it, check to see if there is another one in the hole. Sometimes they used two to lock things. It may not be valid in your case but I spent a very memorable evening in 10 degree weather trying to get a fly wheel off a tractor.
