- Oh man is this bus in need of some serious attention. 60 psi air leak in 10 seconds, bad differential rear end, turbo issues, tag axle swing arm. Lots of heavy lifting on this job. Diagnostic and repairs.

I’m a helicopter mechanic and we always joke engine and transmission chips aren’t a concern until the chip has a full part number. That chip from the drain plug definitely has its own part number.
Lol love it
A buddy of mine said when he was Marines they would only ride in helicopters that were leaking hydraulic fluid because that meant they had some in it
I am amazed at how bad some of those rigs you repair are, and were still going down the road. Thanks for saving them from the "grim reaper" (scrap heap)!!!!!!!!!
It is amazing....and scary.
Nice to see you back again. Been missing you guys. I don't own a bus and I'm not a mechanic but I love watching your videos. Thanks Scott and crew!
Love it how you can revive a repairable 1969 coach to correct operating condition! The engineers who made it would be so proud Scott.
Scott, I am thoroughly confident that you and your staff will have that girl back to excellent health. Kudos!!!
Your apprentice grease monkeys are doing a fine job. I like how you are there with them every step of the repair. For them this is a once in a lifetime opportunity to learn something that is no longer taught anywhere.
I’m trying to hire one more part time employee… i had 6 new employee job interviews scheduled over that last two days… not 1 single one of the 6 actually showed up.
Bummer. I had people tell me who are from the upper Midwest that in their experience when they have worked in the south the work ethic is much more laid back and priorities are different than up north.😕
32:30 They probably heard the job involved a lot of this, and decided “naw, I’d rather stock shelves at the Piggly Wiggly.”
@@BusGreaseMonkey Dang. If I were a few years younger, I'd consider moving to TN to do this. I'm 65 now. I'm a long distance truck driver originally from NJ. I live in Colorado now. Funny thing is, I'm less than 200 miles away right now in W Memphis, AR.
@George you gotta point. Had a great grandmother (dads side rip) that lived in waycross. Lived there her whole life until she passed.
Unbelievably bad upkeep maintenance on that rig over many years. Seems like the owners just fill the fuel and drive off. Good of you to step up and work those long hours to get it drivable (safe) again. You and crew do great work!
I have the luxury to have a dual stage commercial air compressor in my wood shop. Yesterday was one of the first nice days of the year (Reno, Nevada, right down the mountain from Tahoe, CA). So I took the throw rugs outside and blew them off. With a wide open valve, I couldn't lose 90lbs in 30 seconds. That is one massive air leak.
Yes! New vid just in time for Friday! Big hello from Northern VA
If you used a shop vac to take the dirt from above the air bag, probably wouldn't be so dusty as blowing it with the air hose. Working on the floor under those buses is a daunting job. Have to give you credit for your perseverance. Keep up the good work.
I'm a coach driver and have driven MC-7 coach in service for charter companies, that coach has been the receiver of " El Cheapo Coach Owners Syndrome". As in " It will still go down the road syndrome". Had one guy try to convince me that the bus didn't need to turn right (it only turned left). Maybe that one needed to be titled "Nascar Fan Coach operators syndrome"!
Scott, You must love bluegrass music as I do. Awesome theme song. Thank you.
I absolutely believe people should have an air brake endorsement on their license to drive these coaches equipped with air brakes. I’ve seen so many of these coaches on your channel with massive air brake leaks and other problems with the air brake system.
Very, very interesting mechanical components make up a Bus - love watching you guys work on them - you earn every dollar you are paid to perform this work. It's amazing to me to watch you pull something out that is just crumbles of rust and corrosion - also the amount of dirt collected on the road is phenomenal. Anxiously waiting for the next video on this Bus - Keep 'em coming fellas!

So glad the tornados stayed away from you guys. Great video too bro. Safe travels
Two were coming on a path pointing this way but luckily fizzled out. County north of us got one too.
Happy Easter
Good to see you are posting again, with all the weather going through your area, I was worried about you guys. It sounded like you were having some more fun weather during the video.
Yea. I saw some destruction yesterday less than 200 miles away. Just east of Covington, TN. Obvious tornado. Utility poles & trees pulled out of the ground. Several homes damaged or destroyed.
i personally think Bus Grease Monkey should start his own training course , his knowledge should be taught and kept alive by training many enthusiasts and mechanics
The shoddy repair work you find on some of the buses is scary . Glad you video much of your work on them .
Some serious work going on.
Awesome video.
So thanks for sharing ✌️ Peace from Melbourne Australia.
This bus looks like one of those vehicles that was in a video titled will it run abandoned for 20 years. Can't believe this was actually on the road.
Thanks for the great video! I can't believe the depth and length you guys go to make things right! That bus was on its way to an accident until it found you all. Congrats on yet another heroic save!
Thanks for the video. I figured you and the crew have been crazy with work and cleaning up storm damage.😎
We have been crazy busy. You will see all the buses and projects over the last few weeks.
A lot of hard work ahead. Keep the Kroil handy.
The engine sounds like it is knock, knock, knocking on heaven's door.
Hi Scott I've only just started to watch you channel properly I've dipped in and out for some time until i watched your video on how you got into repairing buses this got me how you went from photography to repairing and rebuilding buses it's absolutely fantastic, I'm a retired British and European truck driver and mechanic and im alway's amazed at how bad vehicles are maintained in the U,S,A, not only buses but most types of transport i often wonder how more people are not killed on the great American hi-ways through ill maintained vehicles, I'm not into detrot two strock engines but the rest of what you do i know only to well but my god you get some frightening thing's come into your workshop just like this buses with all it's air leaks the play in he tag axle bushings and the break diaphragms as rotten as they are, thank's for drewing me into your channel I'll be watching so much more.
Well done Scott. Your usual professional diagnosis and rectification of the problems on this lovely bus.
great to see you back...really missed you...this one is a lot of heavy work..good luck... Ian
Scott, do these customers know how bad their rigs are, or do they really not know about the major safety defects that you show us? I find it amazing that people are operating some of these rigs on the road. I understand that not all people are mechanically inclined, but I would think someone would realize there is something wrong sooner.
Like every time you go to stop the low air buzzer comes on? It might have even been disconnected because it got annoying. Lol
My back hurts just watching.
That differential was a hand grenade waiting to happen, extremely dangerous driving with that blown brake chamber, hat's off to you that's heavy hard work and lot's of it.
That’s a pretty sick MC7
Hi Scott just stumbled on you channel I find them so riveting although I’m not a mechanic I am interested in diesel busses thanks for the uploads uk 👍🇬🇧👌
Boa noite,aqui e do Brasil, gosto muito dos seus conteúdos. Essa música é muito show. Parabéns pelo canal. Felicidades!!!
Really good post !! Thank you. Any knowledge learned will come in handy some day, one way or another.....
I don't know how long this particular customer has owned his rig, but it seems like a pre-sales inspection via video call with you guys could save a potential bus buyer a small fortune. That said, your videos have certainly increased the "bus IQ" of viewers. I know I'll never look at an oil, air, or exhaust leak the same when shopping my next bus!
That said there are only so many old buses on the road and or available for sale so cream puffs are few and far between
Dats what ya call a busy bus 😅 keeps ya busy 👍☮️
Good to get those repairs done👍
The stories this rode hard, and lived fast '69 could tell...
Story about bad gearboxes. Had a box that has a 400 hp motor input, right angle drive that reduced 1750 rpm down to about12 rpm. Took all the horsepower to drive the shaft on a dryer/mixer. Guys were fishing around in it on shutdown and got 3 or 4 gear teeth. They were 6 inches tall and about 2 inches across. This thing is definitely bad. The plant manager said it would be okay and just run it. It lasted about a day and when it blew it cracked the top cover and probably sprained everything else. He was in a hurry to get started up but ended up costing more downtime. This box was about 4 x 4 x 6 feet long.
Welcome back
Great job Scott 671 for life
Удачи вам и берегите тормоза.😀😀😀😀😀
I would love to be an apprentice there😅
great job as always im a little afraid for the guy on this bill you did tons of work
Yes it’s clicking around like a pinball score that just keeps going up and up.
"Is that balanced?" YANK "Yes." 😅
keep the vids comin plz i love yah mechanical work it helps and is knolige i dont have and want to learn more ty huggz
Great to see the Bus Grease Monkey & crew back in action!
few years back i had a marine 8v92TTA on my dyno figured it would only make about 500hp… nope almost 900 i was like i can’t even get that outa a 12v71TTA lol i was impressed
Man Alive , That`s a hurting Unit ,WOW .
What a mess, fortunately for you Scott,the owners of these behemoths have VERY deep pockets 😂
I love how someone put MC-8 and 9 style taillights on that bus. I just wonder if the interior floor was flattened like the 8/9 also.
That poor ole gal hasn't seen any TLC in a long time,,,wonder when it had a safety check(1975 or so),,,it should really run and handle great when ya'll finish,,,
Koni portable lifts would be a great addition to your shop tools.
Yawl are saints. These buses have had a tough life, been road hard and hung up wet, and yawl give them much deserved care.
this bus needed the works
Sounds to me like you guys are probably having some very strong winds today when I hear in the background or bad weather
When were those airbags replaced? 1970?
Awesome 👍👍💯
I hope I'm wrong but this looks like a retired bus from the Atlantis route. It landed in good hands though.
Great Stuff y'all. This work is no easy task. What was the cause of the brake chamber rusting so badly? Is the compressor system not working correctly and pushing water into the system? What a mess!
ABSOLUTELY-----> AWESOME!!!!!!!!!! 🙂
It is horrifying to see the condition of the brake system on a bus that is running down the road. I hope this is an exceptional case not the average. I don't think you mentioned where if had come from.
These are the hidden treasures that can't be seen, only heard until everything is removed to see where the noise is coming from and then the reality hits home....$$$$$$ this is going to cost a bundle of $$$$$$$
This bus was under water? I truly hope you replace the air compressor and the air dryer. I don’t know how you gonna get all that oil and water out of the airline.
I would love to come down and visit you I’ve been working on buses for over 35 years I own a 102dl3 with a 60 series Detroit bus is in good shape I would like to just stop by and say hello and maybe help you out with some free labor
Lots of bads stuff, but normal runs better in a few days work, if all parts are close to you.
Good job
5 ad breaks in a 40 minute video? I hope this was economically viable to fix so many faults.
5 seems comparable to hulu or network television ad breaks i think. Btw TH-cam sets that i don’t.
I'm waiting another video to watching
Curious to know how many miles are on that diff
Is it not beneficial/cost effective to keep some common parts in stock? I'm guessing you keep fluids/filters in stock or have a stock with a local parts house?
Lots of work to that unit.
By all the rust. I wonder how long this bus sat around before it was run ?
That was scary seeing the differential plug with a part of tooth on it! Did it turn out the diff gears were OK? That hunk of metal on drain plug later looked later like it may have possibly come from a replaceable bearing. It would be a good day if that was the case!
I believe the welded housing caused lateral stress in the pinion bearing caused it to fail. And the extra metal degraded the other bearings and caused excess wear on all the components. The low oil condition with it being 1/2 empty also added to wear and heat. Entire rear end swap under $1000 in parts, just plug and play from another mci
@@BusGreaseMonkey That's a relief! I would scared to price out that stuff new- if it even exists.
@@BusGreaseMonkey An MCI rear end swap for under $1,000 in parts seems like a sweetheart deal. I'm surprised there are good used MCI rear ends available considering these buses are seldomly totaled for savage yard parts availability.
Poor old girl has had a hard life but now she’s had the bus grease monkey treatment she’s going to travelling in style again
Sounds like it's raining there heavy.
Lots of big damaging storms here lately
Curious why you don’t hang the tag axle from an engine hoist when you’re pulling it instead of trying to balance it on a transmission hoist?
Holy smoke, these machines look like money incinerators....
purple power makes a great liquid rust converter.
Good Lord! Is there anything on that bus that doesn't need repaired or replaced? Y'all got your work cut out for ya.
I didn’t even show some of the items we are working on.
Was the bus under water? All the rust and dirt maybe points to having been flooded?
Is that a crack in the frame at 19:30?
They need to use those lug nut removers for the automotive world 😂😂😂
Nice tires! Where do you park it?😅
Do you think the bus was in a flood?
Frame cracked at the 19:35 mark?
It sure looks like it. I also think they didn’t weld that left side of that bracket to the frame that the shock is attached to.
Looks like a super oversized Ford 9" lol
The repair bill for this bus must be very very very big.
It should be! This is what happens when bus owners fail to maintain them. This is why States should mandate safety inspections for these converted buses.
Yeah I agree. Need to do a 1 year annual inspection like the CMV’s.
Hey scott
60 psi in ten seconds shite Scott thats a bad air brake system right there
A lot of these buses have more problems than Carter has liver pills.
So much rust. Was that old girl in a flood somewhere?
I assume road salt and it listed everything and it was never cleaned for years
Does that bus have an air dryer ?
I HAVE A 1995 VAN HOOL 40FT BUS AND I KNOW IM GOING TO HAVE TO REPLACE AIR BAGS SHOCKS AND GOD ONLY KNOWS WHAT ELSE. I HOPE I CAN DO IT AFTER WATCHING THESE VIDEOS. IM A 60 YEAR OLD WOMAN SO IM GOING TO HAVE TO GET SOME HELP I THINK.
Not running on 8 cylinders in first 30 seconds
Not a pretty start
People that so badly maintain these things are a nusance and hazard to others on the road . really
There seriously needs to be yearly d.o.t. checks since so many owners do not care.
Seriously what is the point of even measuring the steering geoometry before the bad bearings have been replaced?!
Ok it's good technicanian but I can learn about to maintain and then to be careful at the work
Did you instruct the owner heŕshe needs to drain the air tanks daily? 🤔
