Model 333 fixed bearing part Number 37B

[sam801]

I was cleaning my sander that the belt is very loose. This causes the pad to spin very fast. I want to replace the belt but I'm wondering if the bearing should be free to spin?

Hello sam801,

If your pad is spinning at a high rate of speed you are correct in replacing the 903373 belt. If the bearing, part number 965119SV, in the pad support is hard to turn or is rough when it turns, now is a great time to replace it.

Hope this helps,
