Maintenance; Fan Bearing And Belt Tensioner Lubrication - Chore-Time TURBO MV1864P Installation & Operator's Manual

Maintenance

Maintenance
•Disconnect Power Prior To Maintaining Or Cleaning The Fan. The fan may start automatically causing serious
injury or death.
• Service and repair of fans should be done only by a qualified technician.
• Keep the Fan clean for maximum life and best performance. Do Not spray water on Fan Shaft Bearings, Belt
Tensioner, or the Motor.
• Periodically check the V-Belt and replace if necessary. A bad Belt will cause a substantial drop in Fan perfor-
mance or can break and cause Fan failure. If a Belt rides below the Sheave edge, replace the Belt. (See Figure 13)
®
• Keep HYFLO


•Check Sheaves for wear. Replace if Sheave
groove is worn. (See Figure 13 to the Right).
Fan Bearing and Belt Tensioner
Lubrication
• Grease zerks are provided for lubrication on the fan shaft bearings and the belt tensioner.
• Lubricate the fan every 2-6 months or whenever these components get wet.
• Disconnect power to the fan before lubricating.
• Clean the zerk before lubricating to prevent contamination from entering the bearing.
• Use a high quality lithium based, NLGI #2, grease such as Shell Gadus S2 V100 2. Do not use incompatible greases
containing aluminum, barium, calcium, bentonite clay or polyurea thickeners.
• Slowly rotate the fan shaft by hand while slowly applying the grease. Rapidly applying grease to a stationary bearing
can damage the bearing seals.
• Apply about .10 oz (2.8 g, 3.1 cc) of grease at a time or until a slight amount of grease can be seen purging from the
seal.
