Revo rear a/c annoying sound

[lancepower]

guys,

yung rear a/c ng revo ko may parang kuliglig na tumutunog. kailangan
pukpukin ko ng konti yung housing niya para tumahimik pero pag nadaan
ulit sa di magandang road iingay naman sia. May naka experience na rin
ba sa inyo ng ganito and ano ginawa nio ? If ever kaya ba i- DIY?

TIA

blower motor shaft/bushing has too much friction from dried up lubrication, specially if the car was soaked in flood. try spray on lubricants

[oj88]

It's caused by a worn out shaft bushing on the electric motor (blower motor).

In time, the lubrication dries up and the constant turning of the shaft eats through the bushing. This will make the shaft vibrate and oscillate.

You can lubricate it with a drop of motor oil to solve the noise. But expect the problem to come back once the oil has dried up.

thanks for the reply guys

Instead of oil, why not try some heavy duty automotive grease?

It should be better than just oil in this particular application.

additional question do you know how to dismantle the housing of the rear a/c of revo ? Wala kasi ako makita na screw or clips man lang. Can I use grease to lubricate the shaft bushing instead of motor oil?

Thanks again

I don't think grease can be applied without totally dismantling the blower motor (ie. shaft removed from the bushing). It'll be very difficult to apply grease with the shaft installed. Oil can readily penetrate through the tiny gap if you hold the motor upright and let gravity pull the oil in while manually rotating the shaft by hand.

here is another possibility, maybe you have a paper or some things in the blower fan. In my job here in Iba, Zambales, the most common thing i encountered in a noisy evaporator blower is a paper.
