Bearing Replacement
The Model W1678 26" Double Drum Sander is designed for many years of reliable service. But after long periods of heavy sander use, it may be necessary to replace the drum bearings. Always replace both bearings on the same drum.
Keep your drum sander unplugged during all assembly, maintenance, and adjustment tasks. Ignoring this warning can cause serious personal injury to you or others!
To replace the drum bearings, do these steps:
1.Unplug the double drum sander!
2.Open the dust hood, and remove the mounting nuts, the washers and the set screws. See Figure 57.
NOTICE
DO NOT hammer on the bearing or housing as you WILL damage these precision parts.
3.Lift the drum and slide the bearing block and bearing from the drum shaft.
4.Clean and inspect the drum shaft for cracks, burrs, wear, and other damage; replace/repair as required.
5.Use a screwdriver to pry and rotate the bearing so it is horizontal to the bearing- block mounting flanges. See Figure 58.
6.Slide the bearing out of the bearing block. See Figure 59.
