How do you remove the chuck from a Delta shopmaster 350 bench top drill press?

Take the old pulley to a shop where they sell pulleys and try to match it up. I did that with my lawn tractor and found one that worked.

capacitor or a start centrifugal switch or the power cable or switch itself or the microswitch safetyswitch on the top cover .or control switch itself.

Thread Changing chuck on older Delta drill press This site speaks on the subject of changing chucks. It may be helpful. Also if you search;' how to remove a jacobs chuck from a delta drill press' , you should get several hits I hope this info is helpful....

No you don't have to buy Delta's chuck key. MOST drill press chuck keys are very similar but if you do order another companies key and it doesn't fit, you may be stuck with it. If you have a local tool repair center that carries keys you can try one and if it don't work, return it.
The Delta part number for your chuck key is 1313104. It is avaliable from Dewalt (they own Delta) on their service website at http://servicenet.dewalt.com. You can also get it at aftermarket sites like www.ereplacementparts.com for only $11 plus shipping.

try cleaning the pulleys buy a good belt (gates) install belt and make sure you have good belt tension

can you describe the part, the other part number you furnished are superseded with replacement parts and I can't find this one listed, let me know and I will try and help

not sure if you have a dial on that press to adjust the speed. if it is a dial on the machine make sure you adjust it while it is running.... but it looks like it is belt driven and there will be a series of pullies under the top cover for adjusting the speed.

try this, get something like brake clean or equiv. spray the inside of the chuck and also the spindle, wipe clean with a paper towel. fully retract the jaws and using a block of wood tap on the chuck to seat it on the taper. You might have to move the table out of the way but it will work. If I have helped you with your request would you please rate this response accordingly. Thank you

THERE IS A LITTLE HANDLE AT THE SIDE
PUSH IT UP THEN TAKE OUT THE OLD ONE
AND REPLACED

Check for power at the on switch. The switch on this machine should be electrical so yes it could go out. If it is not the electrical type then I would check to make sure that the internal switch did not brake or go bad.
