Hey man I’m a auto technician. Idk if you have one but u can use a automotive stethoscope to listen to those bearings. We use em to check all sorts of noises on vehicles. Great content btw!
I worked on a superfund clean-up site. They had what are called millwrights to come on the job and set the pumps and motors for everything. They had some really cool tools to get all the pumps and motors absolutely perfect!!!
without a ultrasonic detector or stetoscop , use your thermal camera to see which bearing is hotter , a good sign normally if there is a higher friction
Hey Chris that noice is cause by the browning torque titan belt. There are not made correctly. They just came out with a torque total gen 2 because of this issue
Agreed... Also, for such a "simple" application (belt/bearing blocks), a long stem screw driver can also be used. Hold the grip tight in your hand and press your head firmly against your fist... and you will be surprised, how much your can hear/feel... Our old teacher in the apprenticeship taught us, how to listen to grinding, ball bearing clicking, vibrations, etc... and the young mechanics still laugh at me... oh well
4:03 you can use a screwdriver. One end on the bearing and the other on the bone near your ear. This way you can hear wich bearing is making the noise.
I'm sure you know, but the alignment as well as the two shafts being plumb to each other could cause the issues you've shown here, even if the pulleys were in good shape. Brought this up because it looks like the motor is not in good alignment with the fan shaft.
Belt manufactures produce matched belts for multi-belt applications. They are designated by matching number on the belts and should always be changed in pairs.
I still try to get 2 belts with the same run number on them. Belt manufacturers claim it doesn't matter anymore because their manufacturing tolerances are so much tighter than they were when I started 30 years ago. I say bullsh*t, give me a matched pair. Sadly, I can only find that at a the one industrial bearing service company left in my area, no HVAC supply houses seem to even know what I'm asking for anymore, unless there is a really old guy behind the counter.
Stethoscopes are for rookies, all you need is a screwdriver (anything solid really) touching the bearing housing and your ear on the other end. You will know if it is a bad bearing because you can hear everything VERY clearly!
Torque titans have two generations. Generation two has larger and more spaced cogs with it also being deeper slightly. The generation one torque titans are thinner and I have had many issues with this one. The gen 2s are far better quality and should be used instead of the gen ones
Putting some wax on the belt and the squeeling stops, it's the belt/pulley. If it stays it's the bearings. Not a hvac guy but it helped my alternator belt for some time.
I think you can do the same thing with a few drops of water - if the squeaking goes away, it's the belt. If it doesn't, it's the bearings. And the water evaporates in a few minutes and doesn't leave wax behind after.
A solid bar can be useful if the situation permits it to be done safely. Even a big screw driver. Tip on the thing you want to hear, handle pressing in ear or on your skull (really). I used to do this to hear how stepper motors were performing. I could hear bearing rumble and even pick the step speed / acceleration. In my IT days it would even let me hear the actuator in a voice coil type hard disk to see if there was any abnormal sounds. Very useful in a pinch. Again, only done if safe.

With an adjustable dual belt pulley, close enough is all you will ever get, as when you adjust it, the belts move apart or together. More than good enough for those low speed units. With high speed belt drives you even need to dial in the taper lock pulleys with an indicator to make them vibration free at 5,000 rpm.
old timers trick to squeaky belts use a bar of body soap to dress the belts comes off with water and should quite it down long enough to get the new pulleys in
The bearings on a fan are number one possible issue but there are ever more than that!Most of them are full of this oil thick thing that they use to lubricate the bearing but it still fails after some time!
I have seen 2 identical belts even tho they were supposedly a match set be just a fraction off.. An It ticks me off I order an pay for match set an their NOT a perfect match 😢😢… but I always put my new belts on an look at where the belt is at on each pully . It may not be 100% perfect but usually it dang close to 99% right on… An as far a direct, drive exhaust fan??? you couldn’t chase me hard enough to give me one free I don’t like them I will not install them! For much the same reasons as you stated an my customer? When they go down they expect me to get them up an running right away not next day .. An I am glad I am not the only one that thinks this world needs to step back an go back to the ways of the 60’s and be kind an respectful of each other ❤
Cmon man do you not own a screwdriver. ;P That is your mechanics stethoscope. You push the tip of the screwdriver against the housing for the bearing and you put your ear on the other end. No I am not trolling you. Try it. It works best when close to the housing of what you are listening too. It works really good against mounting bolts normally. You can use it to listen to all kinds of stuff. FYI that glazing needs to be removed normally. Use sand paper or scotchbrite and wrap it around a screwdriver. Zip tie it on and while running use it to clean off the glazing. Screwdriver keeps the fingers away were something to catch. This method scotchbrite normally works better. Now I would recommend using the mechanics stethoscope and start listening to things before and after you replace them. It will give you an express diagnostic ability. You can also rest your fingernail edge against the screwdriver without the rest of the finger touching. The vibration will be channeled through the fingernail. I am a big rig mechanic for over 13 yrs now.
As for the alignment of pulleys. Look into an analog driveline angle tool for big rigs. If the angles are the same on both pullies and the belts look level should be good to go. An example of what I am talking about is Speedway Motors DECO Magnetic Angle Finder Gauge Tool, 4.14 In. Diameter.
@@UberArchangel I use a digital angle finder that is marketed for aligning woodworking machinery, works great for the task, looks similar to the Speedway one.
The notched belts are always a problem, they are noisy. Equally, adjustable sheaves (no pulleys) are an issue as they have uneven surface (they are intended to be used to do a preliminary set and then replaced with fixed). A screwdriver on the bearing and to your ear will tell you if those are bad and a motor typically makes a lot more noise unloaded if the bearing is bad vs loaded (and how long the sheave keeps moving tells you how worn as worn runs a long long time - and no, bad bearings only make nasty noises just before seize up, with less grease and wear they coast along on the bare balls, grease slows down the motor)
We have noticed the the torque titan belts ware out too fast, they get loosey goosey, squeaks, etc. even though going through all the pulleys and bearing are all good. So we started buying Gates belts and have had no troubles.
CHRIS what if they converted these drive pulleys and belts to the cogged toothed timing belt type used on cars?They last a very long time,no slippage. I wish i could develop a retrofit kit and let it be tried under trial use and see if theres an advantage. Hey i know these keep you making money though the way they are. I know theres direct drive,but i say keep belts but use a timing belt type and pulleys.
Two things with multiple belt systems, and maybe you touched on it and I missed it. One, they need to be a matched set and they come tied together. Not just two random of the same brand. Those first two replacements were definitely not matched nor even the same. So no good there, but you took them off. Two, with a double adjustable pulley, how do you verify that the two pulleys are exactly set the same? Counting the original turns, is just setting it back to what it was before and it worn unevenly before. If those the pulleys are not exactly the same, they belts will be driven at different rates, cause wear and can lead to the squeaking. How would you verify they are both set the same? Amp check with one belt on at a time? RPM check with one belt at a time? I think you get where I am going and this unit did have a problem with belt noise. That one, more worn pulley could indicate the double pulley was not matched between them and it caused one to wear more, in order to try and even out itself. I am sure you can spend a day getting it exact and even being off it's not like it will grenade tomorrow. It will take time to develop problems again. Anyway..... Cheers!
I would have done the same. Only I would have left the old belts on there to be sacrificial and only put a matching pair on after new sheave and Pulley.
3:15 - I can't criticize you at all for that. Grease is a real pain to clean up, and if you get it on your clothes and it gets in the washing machine, you'll never hear the end of it! Happy wife, happy life! 14:31 - I was actually in disbelief that you'd leave the two different belts on there - right up until the scene change where you said you went back and matched them. Then the world went back to "normal." 🤣 Two slightly-different belts can cause one belt to "fight" against the other. I assume that would lead to future pulley/sheave wear or uneven belt wear.
back in the end of 2000es, there was plenty of dvd-rw drives. But if you look carefully, you could find that there was 7 lite-on drives with diffirent names, 3 toshiba-gnusmas drives and that's all. So, could be any chance to find the real ODM manufacturer for direct-drive motors for fans? Or it was in the part talking about oem direct-drive fans already?
Belt manufacturers will tell you that their machine setup tolerances make that not an issue anymore. I say bullsh*t, give me 2 with the same run number!
Are all the bolt ends the same on the pully that pushes it self apart? I wonder if there is a tool with a planetary gearbox that can turn both at same speed
If one pulley is worn smaller, more than the other you will get a gear ratio mismatch as one belt tries to go faster than the other = sqealing, so obviously both pulleys needs replacing.
it'll be fine, the equipment being greased will generally have near zero back pressure and clogging. unlike automotive and heavy equipment, that sometimes take huge forces to grease.
When greasing the bearings do you just need to apply the grease to the shaft or the bearings themselves? I DO REGULAR MAINTENANCE FOR YOSHINOYA AND THEY HAVE AWFUL EXHAUST FANS JUST SAYING 😂
Oh he actually addresses this later in the sit down. OK, so if the problem is not being able to find the right motor on a late Friday night, and if you’re using the manufacturers that use generic motors, wouldn’t you still have the exact same problem if a belt-style motor broke on a Friday night? The only difference with a direct-style system (vfd? Variable frequency drive?) is that you’re eliminating possible points of failure. The belt can’t break because it doesn’t exist. The pulleys can’t break because they don’t exist. The only thing left to break is the motor and you’ll have the same level of difficulty finding one of those on Friday night either way unless you’re going with the greedy manufacturers. No? EDIT: ok, so the premise that the generic vfd’s are stocked locally like the belt ones is false. Gotcha.

Chris I get the grease all over the place!! I get it on my clothes or my tools. Smart way to keep the grease gun from spewing grease everywhere !!
I always use an Allen key to insert between the variable pitch sheaves when replacing them. Makes it super quick to get them adjusted.
In a dual belt or more situation you must get MATCHED belts. Jim Z- Fan
The belt drive no VFD setup seems way more robust. Keep it simple and reliable.
