• After disassembly, clean all components and examine thoroughly for physical defects, wear, corrosion
and damage.
• Check all bearing bores for total clearance over the shaft diameter. Replace all lineshaft bearings
indicating wear. The following indicates the maximum allowable diametrical clearance over existing
shaft diameter, in which case bearing must be replaced.
• 3/4
through 1 11/16 shaft - 0.020 clearance
• 1 15/16
through 2 7/16 shaft - 0.025 clearance
• 2 11/16
through 3 15/16 shaft - 0.030 clearance
