I was sanding a communion table that I am building last night when I notice some oil coming out of the case of my skil 448 belt sander, it appears the oil is coming out where the armature shaft goes into the gear box. I would like to know if anyone on here has repaired one of these for the same reason, I am wondering if a repair center would even know how to fix this old one. As far as I am concerned its the best belt sander ever made, period. Thanks for any replies
