It drives the 'squirrel cage' blowers, they pull air through two radiators, one on each side. The air is pushed down on the engine and exit's below the coach.
This brings me memories seeing these MCI TMC MC9 Crusader ii coaches around New Jersey Pennsylvania and going to Florida like to Tallahassee through the 2000’s
And the 2000’s Greyhound lines inc retired the living icon the MCI TMC MC9 Crusader 2 coaches through the 2001 the last time I seen it was at the Greyhound bus station on 10th and Filbert streets in Philadelphia PA in 2000’s when greyhound was phasing out it’s fleet for the MCI MC12 and 102DL3 and D3 coaches
Center axle is drive axle. Tag axle is to prevent other axles from being overweight when bus is loaded, only rated at 6k though. Newer buses are 12-16k I believe. Wobbly belt is normal, once the air cylinder fills with air its tightens the belt and no slack to wobble. Its monocoque construction, very strong heavy duty frame, very clean underneath. Thanks for watching.
Fast idle, there is a switch that raises the idle from 600 to about 1,000 RPM. This is a mechanical engine, an air cylinder fills with air, pushes the throttle and raises it to a preset level. It keeps the electrical system charged, oil pressure up, and builds air pressure faster. In the winter it keeps the engine warmer.
which of the rear axles is the drive axle? and is the other one for better weight distribution? the vertical engine belt (whatever it is for) appears very wobbly; any reason to worry? did these have a proper frame or were they monocoque? i know nothing about this so i thought id ask.
Great power train choice! I did a transplant on on an 81 Eagle, with the 6V92TT and HT-740. It was a great choice! With the stock 3.73:1 axle ratio from the old 8V71, the 92 would accelerate and climb hills very well. However, I did have to "turn up the wick" to 2,300 RPM instead of the 1,875 the engine used in a truck. Detroit Diesel tols me that the 2,300 in a bus wouldn't hurt a thing, and they were right.
Great video, my man!!!! It takes back to my days when I was working with the "Hound" having to do this process everyday to get em' ready to roll.....LONG LIVE THE "9'S"!!!! DEATH TO THE 102D3'S, 102DL3'S, G4100'S, G4500'S, AND THE NEW PREVOSTS!!!! PLEASE RESPOND!!!!
HT-740 was never anything but a four speed. HT-750 was a five speed. However, you could have various arrangements as to when the converter locked up, and it could feel like a different gear.
i do enjoy listening these engines. certainly simple and rugged engineering. im also wondering...there seems to be a little bit of a "flutter" (for lack of a better word) from second to third gear. i've heard it on buses i've ridden before. btw, what do you plan on using it for?
Love the sound and look of that engine! Is that vertical belt system/ pulley, a reliable set up? It really flops around a lot, but ive seen it elsewhere and diff configurations, so it must be ok.
Yep, very reliable. It actually has an air pressure tensioner, so before the air is up, it may look loose. It drives the two blowers for the radiators. The good part is that you can flip a lever and the tensioner cylinder goes the other way, making belt replacement a cinch.
6V92T typically 340 HP, 552 cubic inches. 8V71 typically 300-310 HP 568 cubic inches. They could be had with a turbo, but I never saw one in a bus, when as a bus. However, I never saw a 92 without a turbo, but surely they made them.
Kneeling is typically transit bus equipment. But you could install a dump valve to let the front air bags down I suppose. Standard bottom step to road measurement is 12 to 13 inches.
@zachdaney13 Gutless? It's not very quick in acceleration, but it gets the job done. I've pulled 78-80 up certain inclines, most deep grades were doing 30.
Great video. It's interesting that they (the engineers) thought the cooling fans were best put way high so you had to install a really long belt to drive them. I like to have been in the same room with them when they decided to use this and what the rejected ideas were?
The design they came up with was the best (as usual). Keep some oil in that gearbox and that thing will run forever. This bus was all about function and that cooling system worked great with the power output of these engines and it was a cheaper setup to buy and maintain.
I'll be driving a truck to shortly, tractor trailer I mean. I've been driving a bus the last year and a half, the last one I was let go for refusing to drive an unsafe bus. The pay and the headache isn't worth it. I still like buses though, but driving buses for others...
I got insurance for my bus through Progressive Commercial. Are your plans to convert it into a motorhome? I got my bus registered as a camper, and told Progressive that all the seats had been removed and it would be a camper.
Sir, thanks for your compliment. But, you must be out of your mind to think this is an 8V71, I own and drive this bus, its a 6V92T. :28. Oh, it's not an MC9, its an Eagle Model 20! ;)
And I might add, in the 2 stroke Detroits, they came in 53, 71, and 92 cubic inches per cylinder, and all sorts of power ranges, depending on the application. In the DDEC versions, you could actually buy a 8V92TA with up to 500 HP

Cheers for the reply. Makes sense I suppose. Bit annoying though!

Squirrel cage type blowers.
The old dog still running

Stay home and stay safe.

There is nothing like the sweet sound of a Detroit Diesel
Thank you. I like the 102DL3 one of my favorite coaches along with the MC9.
which of the rear axles is the drive axle? and is the other one for better weight distribution?
the vertical engine belt (whatever it is for) appears very wobbly; any reason to worry?
did these have a proper frame or were they monocoque?
i know nothing about this so i thought id ask.
What is that very long floppy belt running up top?
No major issues. Just items that need maintenance, or lack of maintenance by previous owner.
@daniel022209 I think the lowest HP is 290 HP, and 350 HP is usually top for a 6V92T. I believe they simply do an injector change. Not sure.
wow shes in great condition
This thing sounds amazing!!!!
@asulca593 I always thought that "flutter" was the heavy duty torque converter engaging. Perhaps someone can correct me if I'm wrong.
How come the engine speed picks up when its at idle?
Great power train choice! I did a transplant on on an 81 Eagle, with the 6V92TT and HT-740. It was a great choice! With the stock 3.73:1 axle ratio from the old 8V71, the 92 would accelerate and climb hills very well.

Nice touch with the metal polish :-)
can u make a video of how to start the bus from the inside
I have a tripod its really crappy, first time shooting video, and first time using the tripod. Thanks.
Great video, my man!!!! It takes back to my days when I was working with the "Hound" having to do this process everyday to get em' ready to roll.....LONG LIVE THE "9'S"!!!! DEATH TO THE 102D3'S, 102DL3'S, G4100'S, G4500'S, AND THE NEW PREVOSTS!!!! PLEASE RESPOND!!!!
Yup, that's a big 10-4. This used to be an old Greyhound, 4905 was her fleet number. Then spent some time in Miami.
Ok im anticipating purchasing a mci. I had a very bad experience with a eagle i owned and i don't want to repeat the same mess with the mci.
anyone know if the Allison HT-740 came with a 3 speed?
HT-740 was never anything but a four speed. HT-750 was a five speed. However, you could have various arrangements as to when the converter locked up, and it could feel like a different gear.
I believe the J4500's use a 'gear box' that powers a PTO style fan blade, I think there is a fan clutch with two speeds.
can u control the fast idle speed?
i do enjoy listening these engines. certainly simple and rugged engineering.
im also wondering...there seems to be a little bit of a "flutter" (for lack of a better word) from second to third gear. i've heard it on buses i've ridden before.
btw, what do you plan on using it for?
very nice bus we just got the same kind not too long ago.
what does the huge pulley at the top do?
What's that belt turning up there?
I love this video!, The only problem, thats not a 6V92, its a 8V-71. All sound that way and all painted that green.
@ClassicTVMan81 Both the 2 stroke and the Series 60 are great motors. It's nice to drive both time to time.
@daniel022209 fast idle or low idle? Mine is 290 hp I believe.
nice bus..love it
Have you had any major issues with this bus, as far as repairs that cost you alot of money?
LOL @ The "Detroit" sign in the front windshield... am I the only one who caught that?
Love the sound and look of that engine! Is that vertical belt system/ pulley, a reliable set up? It really flops around a lot, but ive seen it elsewhere and diff configurations, so it must be ok.
Yep, very reliable. It actually has an air pressure tensioner, so before the air is up, it may look loose. It drives the two blowers for the radiators. The good part is that you can flip a lever and the tensioner cylinder goes the other way, making belt replacement a cinch.
Great video! Love the sound of that Detroit 6V92! Got a nice sharp growl to it! Running straight pipes or a muffler? Is this the HT740D or HT740RS?
Yup, had a 6V92T when I got her. Although having an 8V71 would be nice too!
i wuld love to drive 1 of thos
Drives the cooling fans.
@studpuppy69
How much HP is on your 6V92T cuz I love the sound of it when its in idle.
@Whug01 It's behind the lavatory wall, on mine its behind the mirror.
6v-92, 8v-71. whats the diffrence in these?
6V92T typically 340 HP, 552 cubic inches. 8V71 typically 300-310 HP 568 cubic inches. They could be had with a turbo, but I never saw one in a bus, when as a bus. However, I never saw a 92 without a turbo, but surely they made them.
Hermosura de motor
@studpuppy69
Hey do you know if you can change the horsepower on the 6V-92. Like some have 253HP and other have like 335HP. Is that possible?
Does that bus have the front kneeling feature, or is it naturally low like that?
Kneeling is typically transit bus equipment. But you could install a dump valve to let the front air bags down I suppose. Standard bottom step to road measurement is 12 to 13 inches.
No jake brake, just take it around the block once a month and poke around with it.
If you liked this video, check out a cold start in the low 40's in my other vids.
Geico and Progressive should offer, try Statefarm to for RV. They should do commercial policies too.
@zachdaney13 Gutless? It's not very quick in acceleration, but it gets the job done. I've pulled 78-80 up certain inclines, most deep grades were doing 30.
The only thing worse than a v6 is vd Unless the v6 is a Detroit

Sounds very close to a 6v-71 reminds me of the old city buses....
that long belt looks verrry dangerous
@retcan
Umm, I don't know who told you that and where they got their info, but they're wrong. You where right, good job.
I'll be driving a truck to shortly, tractor trailer I mean. I've been driving a bus the last year and a half, the last one I was let go for refusing to drive an unsafe bus. The pay and the headache isn't worth it. I still like buses though, but driving buses for others...
Damn, this is some hard core bus porn. Love it!
I got insurance for my bus through Progressive Commercial. Are your plans to convert it into a motorhome? I got my bus registered as a camper, and told Progressive that all the seats had been removed and it would be a camper.
Nice bus... are you planning an RV conversion?
Sir, thanks for your compliment. But, you must be out of your mind to think this is an 8V71, I own and drive this bus, its a 6V92T. :28. Oh, it's not an MC9, its an Eagle Model 20! ;)
That looks like a MCI mc9 not a tmc but sounds great
remove the muffler!
no.
6v92 is a v6 diesel the 8v71 is a v8 diesel.
And I might add, in the 2 stroke Detroits, they came in 53, 71, and 92 cubic inches per cylinder, and all sorts of power ranges, depending on the application. In the DDEC versions, you could actually buy a 8V92TA with up to 500 HP
Now your camera will smell like a bus motor. There are worse things.
