Hello dear friends today in such a short video let's try to talk about bearings
mounted units and how to determine which part of the spinning produces extraneous sounds
I hope the camera could be heard but is barely noticeable whistling bearing
it is especially well audible on
cold when the machine is only just started after the night stood and
just a minute later, the extraneous sound gradually disappears becomes quieter and quieter motor continue to work without any noise
looking ahead I will say that I have already determined that this is the air conditioner pump bearing
he starts to behave badly but I would like to share with you
as you can see which units or which units the bearings started to fail
let's start with the top
it
power steering pump but here in principle everything is clear
if it is the hum if it is a crack it is at the top and
it will not be difficult for you to understand that extraneous noises come from it
generator which is level below here already
it becomes more interesting sometimes the generator can produce the same whistling sound as now published
air conditioner pump
also, sometimes the generator can produce a hum and this hum is very easy to confuse with
power steering pump
because lean in and listen from here from here from here from just anyone and it seems that here it is the source of the noise
the generator can be checked without removing the belt because the alternator pulley is the clutch when you turn off
motor
generator rotor
after all, it was the seat belt is in place still continue to do some revs and when the generator
began to howl bearings or whistle to crackle after you turn off the car it's yours there is a crackle or whistle
will remain until
the armature of the generator will not stop there is literally 1 second but it is enough to identify a fault in the generator
I'll take off the belt
let's touch each unit separately each bearing and talk about it
let's start with the power steering pump all gently all gently
no extraneous sounds and no extraneous
sensations when you scroll
generator
I would pay attention to the sounds in the brush knot area
maybe soon there will be a suitable bearing and maybe brush the time will come to understand
also check the clutch
what scrolls I sharply spin the anchor and
coupling
I stop the anchor after that continues to scroll a little more
Muff works well for it need to
from time to time to look and if she suddenly starts to crunch whistling it is necessary to replace it at once
tell the story of my experience it happened to me I was driving the S80 and at the traffic lights on my dashboard
the inscription is given that there is no charge I come to the light already obtained without charging
stopping the car.
I open the hood and watch a terrible picture of the belt I have torn off and
one end of the belt burns with open fire I ran into the car forgot even that I have a fire extinguisher grabbed
thank God there was mineral water
side by side lay grabbed the mineral water and filled it was a clutch of old age from development became
slip that is, the clutch is red-hot
burned the belt and managed to set fire to the ragged end of the belt joke is not very nice had to call a tow truck
loading the car to bring her home is the end of the story.
then there was of course replaced the clutch put the name of the machine went on
the tension pulley is in good condition, no backlash, nothing is spinning freely torsion-free and does not interfere with
air conditioner pump
no backlash but the sound but the sound is not good
I hope you heard this sound is the sound of a semi-dry bearing to the owner of this car I will recommend
to prepare for replacement as these the floor the minute
whistling in the cold would move in a constant whistle and the crunch of already hot in the end, if this bearing is not
change it can break the seat and then have to remove the pump and
to give the repair when I take off the belt and check all that is attached
don't know it's probably not quite right and
experts probably scold me for it I still start the car without a belt to
make sure there are no extraneous sounds from
gas distribution mechanism and if you want to check as well as checking I check so calmly because I have a view
when the machine starts and
the generator is not working the system
will fix the error, not even one but two errors
sometimes the system just gives errors in the log and sometimes falls out the check on instrument panel
so if you have something to clean erase the error then you can try so on
a short time to literally start
stand for a few seconds to listen quietly, so quietly that if that is so removed the casing and
then the car starts and listens to everything already with removed cover to determine the fault for errors
memory errors now generator open circuit
electrical damage to the generator open circuit mechanical damage of the two errors gives a direct view of
offers to perform an action on one and the second scenario
the motor operates purely by extraneous noise from the timing mechanism
no need to store the strap in place to clear the codes and give the car
read the type of error and we get
generator control module electrical fault
the control module of the generator mechanical error
erasing errors
the inspection mounted units finished light easy repairs all the best and see you soon
