Could be, be also you need to check both fan blades. One could have a dirt dobber nest or something ellse on it. This will cause the motor to be off balance.

The front right tire on my 95 plymouth neon shakes an grinds when im going going straight or taking a right turn but only when im accelerating then stops when i press harder n the pedal. My drive shaft...


CV shafts "look" fine even when they're not. Grinding when turning or on acceleration is almost always the the CV joint. Replace the right side CV shaft. As far as the bearing being "loose", it is a pressed-on unit. I'd probably replace that too. Make sure you torque the CV spindle nu to the proper torque value. If you don't and it's too tight or too loose you will get an early failure of the bearing.

A/C NOT COOLING, NOT ICED UP. MOTOR TURNS BUT THE FAN IS SITTING THERE LOOSE. IS IT SUPPOSED TO TURN OR BE CONNECTED TO SOMETHING? I PROBABLY WILL CALL A PRO BUT JUST WANT TO UNDERSTAND IT. ANY HELP?


Fan is loose on the shaft? Are you getting any airflow? That could eventually ice up your evaporator coil as well as damage the motor shaft. Is there a set screw you can tighten on the shaft?

2oo5 dyna low rider shakes


Not likely the crankshaft. Check the motor-mounts though, problems there, loose out of alignment etc could be the problem. If the front end shakes it could be wobble, check tire condition, age and cupping, balance and wheel straightness, damage, wheel bearings and axle not loose, if a laced wheel check spokes for tightness.

Whynter Portable Air Conditioner Model: ARC-14S. Problem: It sounded as if something fell inside the unit while it was operating (cooling) then it started to vibrate horribly. The vibration is only...


Hi,Whynter Portable Air Conditioner has many moving parts, and they all make noise and cause vibrations. Some of these parts are more likely to causing shaking and loud noises, and sometimes this signals a larger problem, something to watch and scrutinize. If serious enough, it calls for a repair.

Loose Parts

Loose parts cause the majority of shaking and vibration noises in your air conditioner. A few of the most common loose parts include the air compressor, the piston rods and even the fan or blower unit itself. These noises are clunking, clanking sounds that occur along with a vibrating action. The only method of repair is a complete compressor replacement, which is a repair only a certified air conditioner technician is qualified to make. The compressor is a fully sealed component, so individual parts in the compressor cannot be repaired.

Fan Blades

Fan blades cause noise, shaking and vibrations even when properly secured. If fan blades contact the exterior structure of the air conditioner due to a bent fan blade or broken and misaligned grate, a constant, repetitive noise and vibration results, which sounds like a ticking or banging from the interior of the air conditioner. Vibration in this case is limited but still present.

Mounting Brackets

When an air conditioner shakes, there is a problem with the mounting brackets. These brackets hold the air conditioner compressor steady as it operates. Normal vibrations and shaking would otherwise occur without these brackets. A loose mounting bracket causes the air conditioner to rock back and forth and creates a clanking sound. As the compressor starts up, this rocking and clanking sound begins, resulting in a very loud and fast vibration and noise. It also occurs when the unit shuts down.

Other Sounds and Vibrations

Sometimes air conditioners squeal, hiss, hum or screech. Each noise is often accompanied by a vibration. Humming sounds along with a vibration may indicate a bad capacitor, the electrical part responsible for starting the machine. Hissing sounds tend to indicate a pressure problem while screeching and squealing sounds are fairly common in window air conditioners and in central air conditioners. This sound is also a result of the compressor motor. It usually starts when the unit turns on and continues through its normal operating cycle. Vibrations always occur in the air conditioner due to moving parts and the compressor motor's operation.


Hope it helped..

My Fan is somehow loose and gets jammed. I don't see how the fan metal bracket fastens to anything and therefore is sort of floating loose and the blade keeps rubbing up against the plastic...


Fan should not be rubbing up against anything. I don't think the fan is secured properly to the motor shaft. Tighten down the metal clip that holds the fan onto the shaft. Make sure it's not back too far.

Evap fan noisey. this is the 2nd one I put in.


The fan can not be allowed to vibrate (firmly attached). The motor shaft must be straight. Every blade on the fan must be of the same weight and pitch. Every blade on the fan must be equidistant from each other.
In the event a fan begins to shake, the shaking will cause problems in the other. ie: A bad blade will quickly cause a bad motor. A bad motor will quickly cause a bad blade.
Did you replace both the motor and the blade simultaneously?
:o).

Good morning, I have a hayward agph models h100Id1, Went to turn it on yesterday and it started fine but then started banging and shaking. Cobwebs? I read something about the diverter plate might be...


I'm assuming that you have checked the water circuit and have bleeded it correctly and thoroughly - air bubbles will cause that when they go thru the heat exchanger.
The banging and shaking are caused by the blower from the burner- it's either:
1 - the motor is dislodged from its casing and the blades of the propeller fan are hitting the case walls - the casing will have to be opened and the motor refitted properly;
or
2 - the bearings of the shaft of the motor of the blower are damaged and the shaft oscillates - the entire blower will have to be replaced, here's a new one - number 2http://www.poolpartsonline.com/p-11-hayward-h100id1-h100idp1-above-ground-heater-parts.aspx
or
3 - the propeller is loose on the shaft - the blower will have to be dismantled and the propeller reattached .
Here is an exploded diagram to help you with the dismantling

Blower moter shakes whole van when turned on, a/c or not, what may be the issue


motor bearings or perhaps missing blade. Remove blower and inspect fan for irregularities. If irregular, replace fan. If fan is OK, try moving shaft back and forth in bearings. If bearings loose, replace motor. If you have more questions, please reply.
