HOW TO INSTALL OR REPLACE SELF ALIGNING BEARINGS
INSPECT THE SHAFT
Carefully inspect the shaft prior to installation. Make certain that it is free of burrs that could cause machining to wear to the bearing (bushing), resulting in premature failure.
DO NOT OVER-TIGHTEN THE BELT
Tight belts contribute to bearing failure. A V-Belt "tightens" itself as it wraps around the sheave, or pulley, by wedging itself into the "V" of the sheave. Belts should only be tight enough so as to prevent slipping on blower startup.
USE NON-DETERGENT OIL ONLY
When installing or re-lubricating the bearing, use only a 20 or 30 weight NON-DETERGENT oil. The use of a high-detergent automotive engine oil can contribute to premature bearing failure.
- Wipe bearing shaft clean.
- Apply light film of lubricant to bearing surface of shaft using same type as is contained in the ball unit.
- Install shaft and tighten up pillow block fasteners. Tap shaft with one swift motion with a rubber or wood mallet to secure final precision alignment of the bearing.
- When the shaft turns smoothly and easily, washers, collars and pulleys may be fastened in place. Collar clearance should allow about 1/32" shaft end play.
- Install belt; adjust tension. Avoid excessive tension.
- Lubricate. view lubrication help
Note: If the shaft must be removed at any time, be sure to first remove all burrs including those raised by set screws to avoid scratching the bore of the bearing.
