20 Yr Old 10" Delta Table Saw is struggling

[193010]

All of a sudden, my blade is receiving a lot of resistance. I heard it struggling to turn so I turned it off. I can feel the blade is difficult to turn. Oiled it up with very little improvement. Can anyone give me advice on how to diagnose or repair the problem or give me the name of a repairman that will do a house call in Central New Jersey?

Do you have a model number or catalog number of the saw? It should be a 34-??? number. That will help to let you know what might be wrong. I suspect it is going to be the bearings on the arbor.

Hello greatsign1,

It's most likely is your arbor bearings or in a few cases it could be the bearings in the motor. To check this, first unplug the saw from the power source. Then remove the belt from the arbor pulley and motor pulley. Rotate the arbor, if it spins easily with no resistance and noise the arbor bearings should be okay. Then do the same with the motor. If the motor bearings are bad take the motor to a local motor service shop in your area and the can replace the bearings for you. If the arbor bearings are bad they will have to be replaced.

To replace the bearings you will need to remove the arbor bracket by removing the arbor bracket shaft item #149 on the diagram from the front trunnion. Once you have the arbor bracket out. Remove the nut and the pulley from the arbor. At this point you might need a press to get the arbor out of the bracket. Once the arbor is out remove the bearing closure nut that is holding the bearing in the arbor bracket. remove the bearing from the bracket and from the arbor ( a press will be needed for this.) Make sure the arbor is not scored or pitted where the bearings sit or you will have to replace the arbor also.

Replace the bearings, reassemble and you should be good to go.

Or once you have the arbor bracket out take it to a local tool and machine service shop and they will do this for you.

Good luck with your repair,
