A lot of bus companies would intentionally reduce the amount of throttle the driver could use with the foot throttle. Even trucking companies do that. A company I grove otr for when I’d climb the hill on I80 going west I’d always have to downshift 2 or 3 gears each time up the hill so the next time I was at the shop I asked the mechanic if the engine was turned down. He plugged the computer into the truck and after he checked the readings said all you got is 65 percent throttle. I handed him a hundred dollar bill and he reset it to 100 percent. Engine was a 1996 Detroit series 60 rated at 470 horsepower but was only producing 388 horsepower when I brought it into the shop. It got 8.7 mpg after the upgrade. The boss went nuts when he found out and I told him I was getting better mpg and wasn’t dropping one gear at 80,000 pounds gross weight. When I got back the mechanic hooked up his computer and printed out what the engine was doing and surprisingly the boss stopped bitching about it. Food for thought
@@joemama8379 The new engines are computer controlled so you can set the torque, horsepower, and speed in addition to other items, how long the engine will idle. Most companies now control how long you can idle for fuel consumption.
Sure have missed Hank and Bobby and the bunch since we left satellite TV and moved to the internet. Thanks for the reminder...and great work on the rig...
That MCI bus sure appears to drive fast and smooth! I thought Prevost were suppose to be the best at that, but this MCI did a better job of rolling over the river bridge joints at speed better than I recall any of the other buses. It seemed quieter up around the driver and the impacts the suspension was taking hushed compared to the other busses than run this route.
32:45 - my car's power steering made that same sound for weeks, and when I checked PS reservoir and found it low on fluid, I thought that I might have "smoked" the PS pump. I looked on RUclips and found that after bringing the fluid to the proper level you should turn the steering wheel to full left and full right lock several times to purge the air from the system. When I had initially checked the fluid due to the noise, I noticed that the fluid was foamy, so this advice made sense to me. After following the turn lock advice, the noise went away, and a year later the pump is still quiet, so the pump wasn't "smoked" by running it low for a couple weeks. One slight difference here is that my pump made that noise all the time, not just when making turns.
The other thing you can do, is put a vacuum on the reservoir, with like a mityvac hand pump. I take them to 10-15" mercury. Nothing crazy. They whine even more while under the vacuum. Release the vacuum and it all goes away. Ive had that work several times now.
Scott, have Tom check his coolant sensor. I recently had a similar intermittent irregular idle problem. Live data showed the coolant temp swinging over a 60 degree range (hot) too fast to be real. I replaced the sensor and no more idle problems. Great Vid!
Next time Tom comes through with his bus you might check the backup light circuit as when he selected reverse it turned on the yellow turn signals instead of the backup lights Scott. Food for thought
Ya'll need more air storage for the shop compressor. You can hear the impact running out of air after about 30 seconds of use. I love the test drives. Beautiful country up there.
Great video gentleman tons of work but we'll worth the effort loved the MacGyver socket fix, It's not stupid if it works, and when Scott yelled out release the parking brake all could think out loud was, release the kraken let that beast out. Great team work as always.
In 1971 my dad put a bigger engine in my car. To "keep me out of trouble" he adjusted the throttle so it would only open 3/4. I foolishly admitted finding and correcting it to him.
The compression ring on that plastic air line is for copper tubing. The proper one has a ridge around the middle forcing it to seat squarely. Leaks (or worse) are what you get using non DOT fittings
some on face book market place in Rush city MN ,just listed a 8V92 turbo DD for $1500.sounds like it mite be a military take out engine .maybe one of your patrons mite need it
Wow..........I have been "Subscribed" for quite a while. That is the most "commercials" I have seen on anybodies channel! Love the content........the "interruptions" though.......Not sure you guys have any control over that or not.
Really REALLY is too bad about not getting to see more specific turbo boost numbers on first gear. Seems like a crucial test that casually just ended up not happening.
@@BusGreaseMonkey yeah, but they are all save if you put a line in the right place. lines are great, especially when you you are backing in somewhere. paint is cheap insurance
Not to give you another thing to maintain or check, but the line idea seems like a good one if you use different color lines for the different heights of the hut. Would eliminate the S.W.A.G..... Say, blue for 13ft 6in, and other colors for different heights. Yeah, you'll have to be careful if the bus leans or gets jacked up or if the hut sags under snow loads, or sways in the wind, but i think still a good idea to designate a "do not exceed....." zone.
how many metal clad bushings do you do scott.. you should be able to have a machine shop do a 2 sized stud so you can thread the stud thru the backing plate.. and use a collar and a hydraulic ram with a hole in the center to pull the radius rod inert from the frame.. putting nuts and washers on the custom pulling stud... to pull it in.. same thing .. just thread the stud in from the far side and pull it in with with hole in the cylinder hydraulic ram..
@tom feller my dad's name is Jay Frierson I myself spent a lot of time on that coach with him I remember it used to be my favorite coach that 8v92 used to run like hell
is the Oring on the plug held in with the cotter pin. a Hydraulic packing instead of an Oring.. or does it need an Oring with thicker cross section and higher durometer needed..
1:21 - Scott was the hose end gapped to allow the compression collar to clamp down when the nut was run down into the fitting or was the "plastic?" pipe bottomed out? If so, that is a mistake I see that has been the cause of 75% of the compression fitting leaks I have seen. (the other 25% being movement at the fittings). I have seen collars cocked off center from the hose worse than that and still seal as long as the collar was located on the hose with room for the nut to run down and compress the collar around the hose and within the fitting and nut. Compression fittings are forgiving as long as they do not see much live movement after initially installed.
where are you guys located. I am going to purchase a bus in the future and you give very good instruction on everything and I would like you to take a look at my bus when I purchase it.
Is that windshield cracked only 1/3 of the way?? Can't they drill that crack out to stop it and fill the split? Gots to be a lot cheaper than a whole new one! Great job again Mr BGM&S
Oh oh…..driving that hard on gravel. I attended a two day drive training on all sorts of pavement and one thing I learned there was driving fast with a bus is easily done, on most sorts of road surfaces. However, correcting a bus if it starts slipping away needs real craftmanship, if it isn’t too late already. No offence meant but I wouldn’t have felt comfortable driving on gravel that fast.
You gotta figure a lot of these buses are ones that were finally retired and made it into private hands. They made it to a point where they need a lot of maintenance and the fleets figure the maintenance costs were more than they were worth. So they get sold with a laundry list of problems and most private buyers don't know how or what to check.
It’s maintenance that is put off. That blower was probably removed for the first time since the bus was made. Radius rod bushings, they may dry rot over time. There’s too many factors.
It's basically a repair shop so that's basically what you're gonna see. Kinda like going to your local car dealer service shop...sayin geez these all need repairs
@@smpstech This was a Custom Coach, so never in service as a bus. But deferred maintenance is not unique to commercial carriers. Church buses and individuals can get lazy or poor or difficult to find a good mechanic.
Hey Scott, I have a bit of an emergency on my hands. We're in the middle of a wind storm and a gust caught the door on our 4104 and slammed it open. The door no longer closes/opens properly and an inspection found that the upper hinge cracked and hyper-extended right where it bolts into the frame of the door. I'm going to have to replace it. I _think_ I have found the US Coach website. I'll call in the morning to see if Luke has a 4104 upper hinge available, but if he doesn't do _you_ have a source that might have one? The bus is currently being lived in and has to keep a pair of indoor-only cats secure. Thanks! Les Berg

"Hey Lance" is in reference to a bus owner named Lance whose bus Scott was working on (back when he was still traveling in Lenny, before getting the Tennessee property) for some upkeep and things just kept going from bad to worse. Every time something went bad, Scott would call out "Hey Lance" to get his attention and it became a running joke over the last couple years. As for the video showing the origin, you'd have to go back some 3-4 years in the Bus Grease Monkey catalog, but it's there. Edit: There's a playlist on the channel _literally_ called "Hey Lance"

Man those 8V92s were some powerful engines
They were ok for a 50,000 bus but fall on their face when hooked up to 80k.

Pretty sure they're still just running off a baby portable unit. I may be wrong, but I don't think they have a proper setup for the shop yet.
Amazing that some buses have so many mechanical issues and they still run.
Drove Trucks for years and seeing all that filth on the dash and gauges would drive me insane for sure.
Great videos as always Scott. A helpful tip for airline repairs. Get a PVC/Pex cutter tool, works perfect wonders.
Great job Scott what a craftsman you are top man 👍🇬🇧

How you manage to remove and re-install those squirrel cage fans without bending them is a miracle. What a horrible design.
Change fluid it will help a lot. They have some additives which disappear over time. Pump might be in last part of it's life but some tlc helps.
