PERFECT Diagnostic Tool For Any Mechanic (Game-Changer!)

Do you take BEER as payment ??

I bought two. I misplaced one in my 1/2 acre tool box. I did find it, about a month later.

Good tip, Thanx Steve!!

I modified a pair of industrial ear muffs with a grommet that holds a plug or 1/4" tubing lead to find air leaks at my job.

I remember playing with my fathers mechanics stethoscope when I was a kid back in the 70's. One thing you might want to point out is to not drop it or drag the tip across anything. MAN does that blow your ears out. If you drop it and that tip hits the floor like a spear, JEEZUM CROW does that hurt your ears. POW!!

Prostrate time.

My uncle used a broom stick.

Hi Steve.
Diagnostic tools that save you time, pay for themselves.
I knew of them years ago, and now I need to get one after your demonstration that shows how useful it'll be 👍

Steve, I used to use a cutoff broom stick. I could hear grinding and knocking but not a heart beat. You had to make sure you didn't hit the fan or a fan belt and drive it through your brain.

As a retired paramedic, rotate the ear tips forward at about a 15 degree angle and they'll fit your ears better. Lisle makes one with a funnel and tube accessory useful for air induced sound auscultation.

You can use this stethoscope to hear if a gas control valve is opening or closing on a furnace. I think the intention was to use the metal rod against an engine to hear internal grinding and growling not audible to the naked ear. All sorts of uses.

Looking for a good cover for my snapper 28" rear engine rider?

Those are far better than the old moto mechanic's screwdriver blade against something and handle to the ear.

Somehow I miss this video when it came out. I haven't seen one of those things in years and years. I can see how it would definitely be useful. I think I might just have to go for that! Thank you my friend 👍

Just got one on Amazon, all in (tax and shipping)(I’m in Ontario) for $12!
It was on sale… regular price was $17.

Thanks for the heads up Steve.

Have one I made myself from a throw away stethoscope a nurse I know had. It is $13 on Amazon here in the states. It is a amazing tool.

My father used to put the tip of a long screwdriver on various spots of a running engine or machine & the other end against his ear to do exactly this...

A very useful tool. When I was a kid I used to hold a 1/4" dowel against the housing of whatever bearing I was checking out and put the other end against my ear...sure enough you could hear a bad bearing through the stick. Years later my doctor gave me a stethoscope he was going to replace and I've been using that ever since. Like the idea of the metal rod addition as it would let me reach items I can't reach with a regular stethoscope.

For modern cars where everything is so jammed up that might be a good idea, but over the past 60 years somehow I always managed with a long screwdriver with the pointy end on the object and the handle pressed against my ear. It would certainly work on a weedeater. For balancing multiple carbs a length of steel pipe was extremely accurate, even though I also had a proper air flow meter. Sometimes simple is good.

thats so old school! dad had one!peice of wood works too!

I have had one in my tool box for 30 years...... very handy when needed!

Awesome tool. I bought one about 15 years ago from HF to find a bad bearing on my scooter without taking it apart. I don't think I spent more than $10. I never thought of using it to find stuff inside of walls. Brilliant.

Hi Steve, I have a friend that's mechanically inclined. His car broke down on the highway and wouldn't run. He had the car towed to his Dad's house (because it was close by). My friend told his dad that the car's engine quit working on his drive to work and didn't know why. The father said : Get me a 2x4. He took the stick and put it on the engine block. Told his son to turn the key while he had his ear close to the stick. The son turned the key and his dad told him to stop. He said that the distributor was broken. The son took out the distributor and the shaft was broken. Now mechanics have a tool to listen with, even better.
Take care. Roland

Thanks Steve

Nice video!

He probably still does that.

You can check fuel injectors on a car or truck with it , you can actually hear them click open to determine if one might be clogged

I wonder if it could find a carpenter ant colony, bees

Whaaat? LMAO 😂

Great tool that I bought years ago at Princess auto.
Works well for diagnosing bad idler wheels and belt tensioners, bearings ect. on vehicles.
Never thought to use it on small engines.
Great idea.
Thank you Steve.

Steve, need your help. I just got a stihl ms291 saw. The fuel tank vent is plugged how do I get to it?

I was a ASE Master technician for about 25 years. My stethoscope was one of my useful diagnostic tools. It will help discover internal problems before they break and cost hundreds to thousands of dollars. Great video, great advice.

$8 at Harbor Freight

Great tool that's for sure 👍🏻

I agree. I've had mine for over 30 years.

welp... as an electrician. .. I use a 3ft piece of #4 bare... put it to your earlobe and put it on anything.. You will hear soo well that you can actually see the mechanization in your head

Great vid! Already have a stethoscope (and agree with you), used on engines, but not walls... yet!! 😄😄

“WHAT?” Haha. I ordered these for my co-workers then showed them how to track down noises in pumps and motors.

You should try listening to yourself drinking a beer. Can you tell which brand it is?

Works great for finding bad pulley bearings.

Yeah my dad was a mechanic too yeah he would listen to inside the motor with one of those things awesome video thank you

"What?!"

My first job, when I was 16, I remember the head mechanic answering my coworker's question about a buy he was contemplating: 'If you think you need that tool to do that job, you shouldn't be doing that job'.

Used to work in a service center and I bought one of those 40 years ago. They are great for finding clicks and ticks in moving assemblies.

The first time I ever saw and got to try one was on a Buick fireball 8 that had a loose rod according to the mechanic it was #5 or 6 and it definitely sounded different from the others. I thought it was kinda cool.

🦝

I have one!!! Every sound is one hundred times louder. I don’t usually use it until I need to know something. I usually forget I have it.
Water running through a pipe, haven’t tried that yet!
Cheers Steve 🍻

Awesome tool to have. Great video!

WHAT !?!?
