- This Prevost has been a huge project. But it’s finally coming to a conclusion and a safe to drive bus! This bus was not a road worthy vehicle when it arrived. I get to take it on a test drive. Air leaks, dead batteries and some loose belts are the last few hurdles.
With everything you've had to do with that bus, it was a moving death trap. Lord knows how many lives you've saved by fixing what was wrong with that bus.
I am surprised it didn’t catch fire on the brakes before arriving here. The steering must gave been horrendous too.
Salt and snow, makes mince meat out of most steel type's used in production car's truck's and buses. Unfortunately...
Great job fella's, another road worthy bus..thanx again.
✌️❤️😁
That's got to be sooo gratifying with the tight steering and the way that bus just flew up BGM Hill. Nice work!
Thanks for sharing the Amazon, not being an authorized Milwaukee distributor!!
BGM is keeping the highways and checkbooks safe!
Those tanks looked like they were dragged behind the Mayflower across the Atlantic.
I made a reference in another video on this bus that parts of the titanic are less rusted ;)
@@BusGreaseMonkeyWould you recommend a rusr proofing coating on these new tanks before winter?
They are painted. The rust proofing should be the whole dang thing underneath.
@@BusGreaseMonkey, I know in vehicle fleets that spread salt and do service in areas where there’s a lot of salt that they have installed an under carriage wash system. I’m wondering if the newer bus fleet owners feel that something that a company would install today?
Always interesting reading and watching what you do to these buses. I had a friend of mine from decades ago who was a vintage bus nut and I helped him install his fresh water system because he was just starting his conversion. I can’t remember what the bus was though, but I always thought it would be fun to have one for myself bit other expenses got in the way…..lol..
Eastern rust bucket
I'm amazed at how those huge buses can navigate the square in your town so well, accounting for the length and everything.
Hi mr Crosby I really enjoyed all the video s you are posted,I have been a motor coach operator for fourty years,now retired . I noticed on that video when you,ve done the road test with that prevost Hseries when you took off of your property and made the right turn you didn,t lift the switch on the tag axle I presumed that you know the existence of that switch to help you out to cut the distance on a sharp turn, and put it down after the turn, very helpfull when you drive a 45 ft long bus. keep the good work Jonathan and you from a subscriber in Canada.
It’s only 41’ and on gravel. I leave the tags on unless turning very sharp at on a paved surface parking lot. plus i was testing out that new tag brake setup so i wanted it down for everything
It really is staggering to sit down and think about how many lives you have saved over the years. Do you ever think about that kind of thing? Maybe that’s what drives you, I’ve learned quite a bit from you over the years and I appreciate the time you spend putting together these videos. I also wanted to mention that I miss your son, I hope he posts a video again. Have a wonderful day all of the people at bus grease monkey.
I donated blood again last Saturday to the local blood bank and I can measure my lifetime donations in gallons. That’s the only time i think about saving lives. It’s easy to roll up a sleeve.
Thinking about how wheel bearings looked . Reminds me of when someone welding and didn’t ground correctly . That deep etching into rollers . I’ve followed bad hookups for welding ,surprising how much damage is done ! Thanks for the vid ,great job whipping these busses into shape , some are a real fight !
I think you're really on to something, the pitting on those rollers looked like arc patterns to me too! I wondered if the bus had been hit by lightning...coulda been man-made.
This bus only had one hub get new wheel bearings.
If I may add my two-cents, on those air tanks, I would sprayed a coat of that black in color, autobody rubberized undercoating, or if you want go with the clear rocker panel rock-chip preventer. I would argue it does two things, prevents moisture from getting into the tanks when the vehicle is parked, (if you own a metal roof structure without insulation you know what I'm talking about) and prolongs the overall life of the tanks. Details, details, details. You just know Scott was not going to let that bus leave without the steering wheel being straight. Your customers have no idea how lucky they are to have you (& crew) as their go to person.
Thank you very much sir for your answer and have a good week end.
Rust belt Bus. I remember the Midwest.
This bus served its life in salt lake city
I've been in Salt Lake City. The air is saltier than say in Tennessee because of Great Salt Lake. After running in that air for awhile, picking up dust and dirt from the ground, it would be like running on salted roads, especially after picking up moisture from rainfall.
Here in this country we have what we call the mot that after 3 years every vehicle on the road must pass if they don’t they fail and they are not allowed on the road until the defects are corrected
Some of those busses would be old enough to be exempt...
All made for great viewing on this bro and it can roam the highways in safety thanks to you guys. Safe travels. Ken.
I learned so much watching your videos .😊😊
Learned enough to not buy a bus without a thorough inspection first ;)
I think I might have mentioned this before, but Prevost uses cheap garbage metal in all of their parts. Some of your old Greyhound busses don't look as bad as the Prevost busses do with less years.
Good job and keep going and make it safe as you always do
I never had any luck reusing the quick connect air fittings. Sometimes trying to find air leaks on rusted tanks up here in Ontario Canada was quite a challenge. Almost every belt tensioner air bags leak, even from new. Keep up the good work!
Yeah when they are old they don’t like being messed with
👍👍Damn,that bus have some good pick up speed to it and it very quiet while driving.
Nice paint job, then down hill.
My father drove bus for a living. He was a big fan of the MCI but he did not like the Prevost. We live in NB the Prevost were built in Quebec the next province up from us.
Mci is built in Canada as well
Thanks for the video.
This is a VERY STRANGE battery setup ! There appears to be 4 12V AGM batteries. 3 are wired in parallel (the 3 short red cables coming to a common junction), but the 4th appears to make a 24V system. The bus gauge clearly shows the starting/charging system is 12V , so what is the 24V used for ? House ?
Second, a 12V battery is made up of 6 2.2V "cells". On typical "flooded" lead acid batteries, you can add distilled water to each cell. AGM batteries have "sealed" cells.
Third, the only way to PROPERLY evaluate a multi-battery set up is to disconnect all cables and slow charge the batteries, INDIVIDUALLY, preferably 8-12 hours. After turning the charger off, wait at least an hour before checking the voltage. They should all be the same (one low battery in a parallel setup will pull the others down). Using an old headlight as a test load , connect it to each battery and leave turned on for 5-10 minutes (or the Harbor Freight 100A tester ($20) on for 30 -60 seconds). Then check the battery voltage. Each INDIVIDUAL battery should read within 0.2V-0.3V.
Fourth, part of the parasitic draw is just the DIRT on the top of the batteries. Clean using a chip brush and a bucket of water with several table spoons of baking soda. Rinse well with clean water,
Last, buy a "clamp meter" that reads DC amps (amzn.com/dp/B00O1Q2HOQ). Make certain it reads DC amps. Some meter just read AC amps. Quick test. Clamp on the negative lead that connects to the chassis. With everything off and all computers "asleep" it should be less than 50mA (0.050 amps).
Bus is 24v look at the left gauge. To complicate things a few systems run 12v between the 24v but there is a battery equalizer on the wall in the battery compartment and it balances the batteries. The engine ddec computer system uses 12v but has a minimum voltage of 10.4 i think and when the starter was dropping below that threshold the computer would not fire the injectors
@@BusGreaseMonkey If you are going to go further with the electrical system, DRAW A DIAGRAM ! Use color pencils/ink. Buy some colored electrical tape and mark the cables with colors that match the drawing.
I still stand by one of my recommendation. Disconnect all batteries. Charge at no more than 2A for 8-12 hours. Load test each individual battery for the same amount of time and note the voltage at the end of the load test. My guess is you have one or more bad batteries pulling down the others. If it were my bus, I would replace that "battery equalizer" with a better quality on like a Victron Orion-Tr Smart DC-DC Non-Isolated Charger.
BUY A CLAMP METER THAT READS DC AMPS !
Thank you for your videos. I look forward to watching them. As a backyard mechanic I am in awe of the repairs you tackle. A few questions: Do you turn away jobs that are too complicated or on buses that are too far gone? Do you have problems collecting for the repairs have done?
We bill weekly so owners don’t get blindsided by a huge surprise bill. Estimates never cooperate on antique vehicles. I often tell owners that a repair is going to cost more than the monetary value of the bus. Most still choose to get the repair done. Often after spending 30k the leaves looking exactly like it did when it pulled in. That hard because everything we do is usually hidden out of sight. But the drive home is much safer and enjoyable ;)
@@BusGreaseMonkeywell done sir .. that’s the only way to do it in these situations. Nothing worse than bill shock.
Good luck and God bless
Good job
didn't you work on one old bus that didn't have any belts. that was a neat old bus.
Many GM vintage buses have gear driven everything
my friend is selling property in northern east Arizona. there is a 1953 Kenworth pacific bus that needs a new home before it gets scrapped. it has been converted to a Detroit diesel
it drove too the place it sits 15 years ago
Sunday morning coffee and Bus Grease Monkey 😊
With the Allison software, you can reset the transmission so it we relearn if it’s shifting harsh. I was suprised I couldn’t hear the turbo or jakes very well, it didn’t sound like the series 60/b500 combo I was expecting.
It’s not like there are any windows to open and the rv interior buildout has walls inside.
Everything I've seen regarding these Prevost rigs make me think they are garbage right out of the box..
Time for a steering wheel cover ! Where's that J.C. Whitney catalog?
Black vinyl with perforated foam backing.
I was about to say that those belts looked very loose as well.
Stupid wasted diag to only figure out someone out the wrong size on.
wow what a job!
The fleet # was 4000+! That’s always a red flag for high usage route buses!
Prevost owners call it "zeroing it out" and expect about 30-50 thousand to bring it back to new.
I wonder how long it took the town residents to figure out that's the buses are all coming in and out of Scott's place.
99.999% are clueless we exist.
@@BusGreaseMonkey : And that remaining 0.001% is just you, I suppose?
If more than 1/1000 in our county ever heard of us i would be shocked
@@BusGreaseMonkeyBut the UPS guy knows and he's not blabbing.
That thing is QUIET on the hwy!
This big girl looks a lot like mine. My air system needs extensive work, too. Just gotta wait for funding before I can get her fixed up and roadworthy before I can move forward with the motorhome conversion. My fan gearbox needs a rebuild badly, I fill it and within a few hours, it's empty. x.x My poor H3-45 was neglected by the previous owners. She's rough.
keep the clips coming
old fittingn never work. it is cheaper to replace them. speaking from experience working on boilers and heating systems in hotels.
They are like $30 each so we tried. Every single one leaked
@BusGreaseMonkey ouch!
DOT brass fittings are not cheap
Just replace the o rings. I Do that all the time. Much cheaper than changing to compression fittings.
I have never had luck reusing those quick connect air line fittings.
The lesson learned for your videos: It is very expensive to maintain these big RVs. The weak points seem to be suspension parts. Are they being overloaded? Bearing, shocks, airbags, air system in general?
Did you ever figure out any of that extra wiring on the batteries that might be the source of the parasitic draw?
It's notable how much crud builds up on the steering wheel. I clean mine frequently with mild soapy water. Especially after a PMI - you know, machanics...
Nice work.
Are you driving the same test loop but just showing different parts or is it a different test loop?
Concerning the sticky steering wheel, if you must use sanitizer use the clorex wipes type and not the alcohol based. The alcohol based actually breaks down the surface. Give that a try.
Looks like an Ontario bus.
try to run bigger wire up front and clean up connection on battery with sand paper
Rust never sleeps. 😅
I knew that I think he just hated the Prevost. Lol
Did the client ever make a decision on whether or not they're going to get the ABS system repaired at a Prevost service center?
Not worth the cost, and I doubt Prevost would work on it.
That looks like a Le Bus.
Correct
I have installed industrial compressors and tanks - auto drains are common, blasting out any condensate for a half second every 10 minutes or so. Is there anything like that for buses?
Have you heard from sage lately I see he did some work on his buses
Not really. He’s busy, im busy etc.
My 2002 Ford F250s rubber steering wheel is doing that sticky thing...
The binders in the rubber/plastic are starting to fail with time and it's sticky and nasty and you can't get a replacement...
What’s more expensive- owning a boat or a bus? Hahaha
I love to watch you guys but am always wondering why you don't spray down these rusty corroded bolts with WD40 or something before you even start? It makes your life so much easier?
We use gallons of kroil penetrant oil on everything
" No more than 4PSI in one minute "
No more than 3 psi in a min, it’s 4 for a combination, add 1 psi for each additional combination unit.
@@user-ln7of9gs4s yep. My bad.
How come there are two air gauges? The markings on them are identical, but they read differently. How do you know which one does what?
Shouldn't That Air tank have AHeat shield around the Air tank.
How often do you get those rare manual transmission buses
Yep, a sticky steering wheel and dirty windshield are the two most yucky things......
I always thought that Prevost was supposed to be the premier of buses, but maybe I was wrong? So who actually makes the best bus/coach these days?
They are so complicated with the modern crap it’s crazy. But all the new buses of every make have that crap. I like the old simple vintage stuff.
Corgi. Easy electrical system!
@@BusGreaseMonkeywhen do you think they started getting the most complicated?
I have a 1995 Prevost XL and it doesn’t seem too bad. Wouldn’t want it much newer though.
@andrewabt6327 having norgren valves everywhere is dumb and causes many unnecessary failure points. Just make the suspension inflate to a preset height and stay level. 4104 did it perfectly in the early 50’s ;)
What happens with the ST on Prevo?
Imagine Prevost sending the wrong parts ? 😅😅😅😅
Do you rely on the customers gauges being accurate indicator only? or do you plug in your own gauge? Blind freddy can see these owners are the danger to public safety, disgraceful condition bus,
If you watched this whole series this owner just bought the bus and came here on his first trip to get it looked over.
13:03 I would make sure those wires are fused. If not, add a fuse holder. Fire hazard. 🚨🚨🚨🔥
The bus owner can do that. If i start tracing electrical stuff his bill will really go up.
This bus must have run in the salt all its life, that is a lot of corrosion and rust.
Scott said it ran a route around Salt Lake City.
Belt tensioner works on air pressure??? WTF 😂😂
Very common in buses
Them belts R too Loose
Why don’t they ever clean the gauges
Did those tanks come from China?
13:35 yuk 🤮
The sun
Lol, can't check individual batteries when they are still all connected together,
They are 24v so yes we can check them. They are not 4 parallel batteries.
OK, just strange that dashboard volt meter doesn't show 24v,
@jimprojectgoldwing5536 look left two gauges
@@BusGreaseMonkey actually I would suggest that what you have is 2 pairs in parallel then connected in series, as obviously they are not 4 x 6volt batteries connected in series.
But what ever you say,
If the bus was used in canada. It's destroyed by road salt
Ran around Salt Lake City.
Rusted pressure tanks can explode with devasting effect

nice..but bus drivers and dirty windows..i dont get it
