The blades are driven normally by a pin through the shaft into a slot at the back of the blade centre. the blades are held on by the centre section which is a left hand thread (do it up to as normal to tighten)

2006 Chrysler Pacifica - can cooling fan blades be tightened to stop wobble?


I would say that the bearing has failed and the unit should be replaced . If you have a viscous fan hub the problem may be there or if you have the fan directly on the water pump I would be checking the pump bearing for failure

HI, My Kenmore Air Conditioner Model# 76129 - turns on, makes a sound like it is going to work but the fan does not move. Thanks


When a fan malfunctions, the problem is usually loose or dirty blades. If the fan won't operate or if it's noisy, cleaning and tightening will usually fix it. Here's how to repair a room air conditioner's fan:
What You'll Need
You'll want to have these tools on hand to repair a room air conditioner's fan:
  • Vacuum
  • Soft cloth
  • Screwdriver or Allen wrench
  • Long-blade screwdriver
  • Wrench 20-weight nondetergent motor oil
  • Volt-ohmmeter or multimeter
Step 1: Open cabinet and locate fan.
Step 2: Clean away any debris with vacuum and soft cloth.
Step 3: Check fan blade on motor shaft for looseness. Blade is fastened to shaft with setscrew at hub of blade.
Tighten setscrew with screwdriver or Allen wrench. If air conditioner has round vent fan, tighten fan on motor shaft by inserting long-blade screwdriver through port in fan.
Fan is installed in its h­ousing with bolts, and vibration can loosen these fasteners. Then tighten them with wrench.
Step 4: If fan has oil ports, apply several drops of 20-weight nondetergent motor oil (not all-purpose oil) to each port at beginning of cooling season.
Step 5: If you suspect fan motor is faulty, test it with VOM set to RX1 scale. Disconnect terminal wires from terminals, and clip probes of VOM to wires.
If meter reads between about 3 and 30 ohms, motor is functioning properly. If meter reads either zero or an extremely high number, replace motor.
To remove the fan motor, remove the fan, the power wires, and several mounting bolts. Install the new motor with the reverse procedure .bobicehouse_59.jpg

I have a model 5BS520C. The light works but when I pull the chain for the fan, I hear the sound of three speeds but the blades do not turn. ed.pfohl@gmail.com


Here some toubleshooting:

Problem 1. Fan will not start.
Probable Cause
1. Fuse or circuit breaker blown.
2. Loose power line connections to the fan, or loose wire connections in the switch housing.
3. Reversing switch in neutral position.

Suggested Remedy
1. Check main and branch circuit fuses or circuit breakers.
2. Check line wire connections to fan and switch wire connections in the switch housing.
3. Make sure reversing switch position is all the way to one side.

WARNING: Make sure main power is turned off.

Problem 2. Fan sounds noisy.
Probable Cause
1. Blades not attached to fan.
2. Loose screws in motor housing.
3. Screws securing fan blade flanges to motor hub are loose.
4. Switch housing binding against the blade hub.
5. Wire connectors inside switch housing rattling.
6. Screws holding blades to flanges are loose.

Suggested Remedy
1. Attach blades to fan before operating.
2. Check to make sure all screws in motor housing are snug (not over-tight).
3. Check to make sure the screws which attach the fan flanges to the motor hub are tight.
4. Check to make sure that the switch housing does not bind against the blade hub.
5. Check to make sure wire connectors in switch housing are not rattling against each other or against the interior wall of the witch housing.
6. Tighten screws securely.

WARNING: Make sure main power is turned off.

Problem 3. Fan wobbles
Probable Cause
1. Setscrew in motor coupling is loose.
2. Setscrew in the hanger ball/downrod assembly is loose.
3. Screws securing fan blade flanges to motor hub are loose.
4. Fan blade flanges not seated properly.
5. Hanger bracket and/or outlet box is not securely fastened.
6. Fan blades could be out of balance.

Suggested Remedy
1. Tighten the setscrew in the motor coupling.
2. Tighten the setscrew in the hanger ball/downrod assembly.
3. Check to be sure screws which attach the fan blade to motor hub are tight.
4. Check to be sure the fan blade flanges seat firmly and uniformly to the surface of the motor hub. If flanges are seated incorrectly, loosen the flange screws and retighten.
5. Tighten the hanger bracket screws to the outlet box, and/or secure outlet box.
6. Interchanging an adjacent (side-by-side) blade pair can redistribute the weight and result in smoother operation.

WARNING: FOR YOUR OWN SAFETY TURN OFF POWER AT FUSE BOX OR CIRCUIT BREAKER BEFORE TROUBLESHOOTING YOUR FAN!!!

Hope helps.

How to remove fan on a 5.2L engine


Hi, 5.2L Engines

  1. Disconnect the negative battery cable.
  2. The viscous fan drive and blade assembly is threaded into the water pump hub shaft. Remove the fan drive and blade assembly from the water pump by turning the mounting nut counterclockwise as viewed from the front while securing the water pump pulley. Do not remove or unbolt the fan drive and blade at this time.
296b572.jpg

Fig. : Fan blade and viscous drive (click for zoom)


The threads on the viscous fan drive are right hand threaded.
  1. Remove the 2 fan shroud-to-upper crossmember nuts.
  2. Remove the fan drive, blade and shroud as an assembly.
WARNING Do not place the viscous fan drive in a horizontal position. If stored horizontally, silicone fluid in the viscous fan drive could drain into its bearing assembly and the assembly would have to be replaced.
CAUTION Do not remove the water pump pulley-to-water pump bolts. The pulley is under spring tension.
  1. Remove the 4 bolts securing the fan blade assembly to the viscous fan drive.
To install:
  1. Install the fan blade on the viscous drive. Install the bolts and tighten them to 17 ft. lbs. (23 Nm).
  2. Position the fan shroud, viscous fan and blade into the engine compartment as an assembly.
  3. Position the fan shroud to the radiator. Insert the lower slots of the shroud into the crossmember. Install the upper attaching nuts.
Ensure the upper and lower portions of the fan shroud are firmly connected. All air must flow through the radiator.
  1. Install the fan drive and blade assembly to the water pump shaft and tighten the nut.
Ensure there is at least 1 inch (25mm) between the tips of the fan blades and shroud.
  1. Connect the negative battery cable.
Take care

How do I remove the fan from an electrolux EGC652 oven


Hello,
The model no. does not seem correct.but it seems as if the hole in the fan blade which is normally D shaped has worn round.The thread on the shaft is Left handed and you will need to undo by turning clockwise. If you can get a vice grips at the back of the blade to hold the shaft then try again,or you will need to get into the back casing and try jamming the shaft at the motor housing you may need some help.Then if that works you will need to undo the 3 bolts holding the Motor body to the rear casing.The new fan would normally come with new bolts,blade and nut.To tighten fan blade nut use a 10mm socket hold the fan blade and tighten anticlockwise.Hope this is helpful.

Good luck.

To remove the fan motor, remove the fan, the power wires, and several mounting bolts. Install the new motor with the reverse procedure. However, if the condenser coil must be moved to get the fan out, do not try to remove the motor. Call a professional service person.

The fan blade came off my attic fan, a Leslie


Slide the fan on the shaft. Rotate the blade so the allen screw is over the flat side of the blade and tighten it down. That's it! Be careful how far you put the fan down the shaft so it won't hit the motor or the fan shroud.

Noise from one of the fans on gyro fan


Please see my Solution to the post about the "HOT" motor, with blades that don't turn.
The Minka Aire Gyro fan heads do NOT have any exposed screws that can be tightened. Checking the rear (wood color) pointy trim piece -- first loosen, turn fan blades a bit, then it. tighten back up.

If your fan was just fine before, and now it's cranky, the problem could be the motor head's "tweaked" out of balance: EITHER from the rear trim piece (see above), or from the twin support arms. OR, the fan head has somehow gotten off-kilter and is whirling out of balance.
FIRST, gently rock each fan blade - they are PVC plastic, not wood, and should not Warp. Do they all look the same? Do they feel snug or loose in the fan head? IF that's all good...
1) With the fan OFF, swing that motor head thru it's up and down range a few times, make sure it's moving like the good one.
2) do the above-mentioned pointy trim piece thing, and the "swing thru" thing; rec-check BY HAND to see if it's corrected.
3) If not, check for fan head wobble by slowly turning the blade (fan head) and see if it's running parallel to the motor head. IF NOT, use a thin plastic (spatula) and gently wedge the kiltered side back to parallel - recheck afte each "nudge". It should spin nice and flat with no wobble, and not feel loose, either!
BY HAND: Spin the blades fast - does it bang? NO? great!
Yes? Double check that the grill hasn't gotten banged, and pushing into the blade's path. Re-try the "adjustment" of the fan head - if it still does not remove the problem, then the internal motor shaft supports may be loose, or broken.
Hope this Helps!

Removing ceiling fan blades


Wait? Why would you want to remove the blade? Are they broken? Is the fan unbalanced? Try cleaning the blade. If the fan still wobbles, try tightening the screws. If the fan still wobbles, Unscrew the blade and unconnect the blade from blade iron. Buy the new blade iron. If the blade is broken, Also buy the new blade.
