delta 10 inch table saw

[HENRY IVEY]

I have a delta table saw.model 34-670.the motor brushes are sparking a blue ark when in contact with the armature.is this normal.also the brushes are chewed up.replaced the brushes and dressed up the armature,but the brushes are still arking a blue spark.is this normal.

Hi HENRY IVEY,

The sparking would indicate that the armature itself is damaged. There is a good chance that the field is damaged as well as the two components work together and one going out can damage the other. You will need to take them both to a motor shop and have them tested to confirm which is bad. It looks like from a cost stand point it would be best to simply replace the entire motor. The armature costs almost as much as the motor assembly. The motor assembly is part #906297 and is available from www.ereplacementparts.com.

Let us know how it works out.

I just bought a Delta 34-670 basket case saw. It's in several pieces, but the motor runs strong, doesn't arc, and coasts down smoothly. I'm not sure if I have a Type 1 or a Type 2. How do you tell? The serial number is K9348. Thanks for any info!

The Type Number is used by the manufacture to indicate that a change was made to the tool in manufacturing. The Type Number will be listed on the same tag as the model and serial number information. If no type number is listed then you are usually safe to assume that your tool is the earliest Type number, usually either Type 0 or Type 1.

I hope that this helps with ordering the correct parts for your repair!
