This new building is lucky to have you there and the same for the hotels you service. When I was an engineer back in the day, I wish I had your help. Thank you for all you do and the videos you produce.
Thank you for that! Really appreciate this comment. As long as your building paid their bills, I would have loved to help 😂 Thank you for watching as well. Stay tuned for new videos every week! 🔧⚡️🙏
Thank you very much Ronny! Much appreciated. It didn't come over night! I been in the field since 2011 and I'm constantly studying even now. Thanks for watching 🙏🔧⚡️
I hear that! I thought of that as well, but it was the belt being too dry and worn out. The other guy said all is fine, but clearly, it wasn't. We all learn something new every day! The new belt with belt dressing made a huge difference, and it will really preserve that belt. Always nice to have a spare as well. Thanks for watching as always! 🙏🔧⚡️
I've heard that same belt noise from things on autotensioners. The belts look fine but sound like they're too tight. You make sure the tensioners work and just replace the belts and the noise goes away.
We use Polyrex grease on our motors ( non cooling tower ) they way over greased that sucker and blew out the seals. With normal maintenance...should be 2-3 pumps of grease maximum every 6 months. You can actually figure out the correct amount by using the timer on the VFD. It has a run time counter that can be reset for maintenance. The manufacturers provides a chart for how much grease for how much runtime. Those bearing seals are toasted. I take care of some really large fans, especially for stairwell pressure fans. We have one building where the exhaust fans are over 10' tall and the fan is over 6' in diameter. Just did some maintenance on the parking garage exhaust fans at the TX state capital building. They are Flakt fans and the motors are 100hp and the fan blade diameters are 8' each.
Over greasing is practically as bad as under greasing. It causes greater friction/heat which will kill the bearing life. Additionally, it appears like they may have mixed greases. Mixing incompatible greases breaks down the viscosity of both greases which will also create more friction and kill bearing life.
They should go ahead and buy replacement pillow block bearings because they will likely need them before too long. And purge the greases lines when they do with poly Rex em.
"spare me in the comments" LOL! Because the Karen who will bitch about rolling the belt off has never, ever , ever done that. Right. You're almost to 100k, Good work!
😂😂😂 Facts!! Almost🙏 Its been my goal to get 100k and get the youtune plaque. Been working hard for 5 years with the videos and I'm almost there. Thank you brother 🙏 & thanks for watching! Always appreciate your support 🙏🔧⚡️
I am wondering if the noise was a worn sheave/pulley, misalignment or since the dufus before you jacked things up, even the wrong belt. I am far from an expert, but to me, it sounded like the the belt grabbing the pulley.
I work in a hospital. And as soon as I heard the noise I knew what was wrong with the fan. We have 4 in house techs and management doesn’t understand that over grease kills bearings. They want to see grease coming out of it
Leave a note on the EF for the maintenance guys saying “3-4 pumps of grease, THATS IT” My co worker does like 10 pumps, I tell him all the time you need only 3-4, every bearing he touches he over greases
Belt dressing is only a temporary fix in most cases. It gets flung off the belt and causes a mess. I have seen belt dressing break down the rubber belt destroying it. It's better to clean the sheaves and replace the belt with a new one.
The pulleys are grooved badly, that grating sound are the pulleys being worn down. You don't need gunk for this issue, you need new pulleys. Get the correct set and retain the keys. Oh, and replace the pillow blocks because the grease they used may be the wrong type for this and flushed out the grease that is rated for this. Not to mention blowing out the seals on the bearings. Check pulley alignment and belt tension according to the manufacture, and I'll assure you it won't fail on them for 5-10 years of proper maintenance.
Im confused, i assumed you did exhaust fans like this before in your career. Sounded a bit like a 2nd year apprentice. Belt dressing was recommended to not be used by Browning. If you got a sqeeky belt you can check your pulleys and tension. If your snapping belts on and not checking your alignement. The 3/8 screws do come with the unit as well as the metal tabs they have for the screws.
Greasing bearings is a gray area out there.... What's too much, what's not enough, how frequent to grease.... Should get rid of all greasable bearings... When they go bad, just replace... Removes user error from the picture...
So just for future reference take off the belt if it’s squeaky like that and you are wanting us the viewers to here the motor personally I could not here the motor as the belt squeaking was louder than the motor
Self-tapping screws is just such a cheap and bad solution by the manufacturer. And yes, the one who did the job before, he should maybe reconsider his occupation and start to flip burgers instead.
@genewheeler6320 It's all good. I'm with you on this one. That part wasn't actually in the video to spare the viewer of simply cleaning. Haha thank you! Enjoy your weekend 🤙🔧⚡️

Your knowledge of troubleshooting and general function of HVAC and refrigeration is quite impressive.
Thank you very much Ronny! Much appreciated. It didn't come over night! I been in the field since 2011 and I'm constantly studying even now. Thanks for watching 🙏🔧⚡️
That has got to be the cleanest plantroom you have worked in 😮 good job 👍
Thanks JMT and your apprentice, I bet you guys are a blast to work with!
You're very welcome & thank you! Totally a blast to work with. Good vibes and A+ effort. Thanks for watching Billy! 🙏🔧⚡️
Lol. Me and my helper were just talking about changing belts. Hey, when i 1st heard that belt, i was thinking that the pullys were too tight.

Nice work as always Jumper Man. They probably blew the seals out of the pillow block bearings.
Thank you Steven! There's a good chance of that. Might be time to change them before there is a disaster. Thanks for watching as always! 🙏🔧⚡️

Dear Jumper man Tech: “You pay peanuts you get monkies!” Changing the other guys diapers makes you money.
Wow easy fix today well done JMT
Facts. Easy but very necessary. After that, there was 2 heat pump service calls in the building. Thanks for watching! 🙏🔧⚡️
Very good job with great tech tips ... Good little helper with you as always ... Thx JMT
Thank you! Those tips definitely come in handy. Facts. He's always there when I need him. You're very welcome & thanks for watching! 🔧⚡️
Poetry in motion 💯👍👍👍
Belt Dressing for the win.
Great video thanks for the tips on Greasing
Thank you & for sure! Any time 🤙🔧⚡️
Thank you for your support 💯
good call ...
Thank you!! 🔧⚡️
Great job man
Nice job as always
Thank you!! 🙏🔧⚡️
Great video as always. Good Job and Nice Work. Thank you for sharing. Have a nice weekend ^_^
Thank you! You're very welcome & thanks for watching. You also have a nice weekend 🙏🔧⚡️🤙

Yeah missing and incorrect screws plus over greasing is always a red flag.
💯💯💯
Exactly how we do it in the field

Lastly the panel has a side were 2 screw holes are closer together those belong on the back so the cover was backwards.

It is definitely a grey area. Greaseless bearings would be awesome. Facts. Thanks for watching! 🙏🔧⚡️
😻💚💜💚
💜🔧⚡️
Bet those bearings are shot ! 😊😊😊
There's a good chance! Might be time to change them before there's a "nightmare" title video recorded 😂 Thanks for watching! 🔧⚡️

Too easy for the professional jmt st your service
Haha thank you & thanks for watching 🙏🔧⚡️ Always appreciate your support. I try my best when I do service. Enjoy your weekend 🤙

Bro.😢 clean the pullies as well.
With all that grease it prob got on pullies and dried up
Facts, it did. When we cleaned the unit, we also cleaned the pulleys 👍 Thanks for watching! 🔧⚡️
@JumpermanTech ooo sorry bro missed that
If figured you did.
As thorough as you are
