Finding a noisy bearing - Tip
« on: March 20, 2017, 11:01:20 AM »
I've used the old 'trick' of putting a long screw driver handle against my ear and the tip on a suspect bearing, to hear if it is bad. I've also used the stethoscope.

Here's a new twist on the screwdriver method, shown by YouTuber Eric O from SMA.  thumbsup2

That is a good tip but if he is worried about safety he should do something with his hoodie pull strings hanging down. He is more worried about skewering his head with a screwdriver than getting his face pulled down into rotating machinery. scratchhead

That's an old-timer trick for sure. My old German boss back in the 60's just grabbed any metal funnel that was around, and used it to amplify the noise through his wood handled screwdriver. He just held the driver and funnel together with his clenched fist -- it didn't actually need to fit in the end of the funnel.

Just hold the damn screwdriver! If the bearing is noisy you can feel the vibration with your hand.

I'll have to try that next time but I am willing to bet that takes a bit of experience to get the "feel"of it.  I'll have to double check with my ear,.

I have to admit that I liked the jug on the end. I have used s drivers and mechanics stethoscopes for years but I honestly I never thought about adding a jug to the end of the driver. I like what it did to amplify the sound. So simple it is almost embarrassing I never thought of it.

Yea, I like the simplicity of the jug amplifier.

I have the stethoscope too, but they pinch the h3ll out of my ears.

He does talk about the cords/strings near the end of the vid. IIRC

It's a sign of the sue-crazy environment we live in, I think.

I've seen a lot of disclaimers/cautions/don't do as I do kind of statements.

But, we're grown-up here, right?, and should know which end of the screwdriver to stick in our ears.

I posted it just as a kool twist on an old shop trick.

Thanks for watching.  wavebeer

I got a piece of dowel rod at work. @4ft long @ 1/2"ish works really well to find noisy bearings in some nasty places. You just gotta remember which end is the clean end. :groaner:
