Excellent job well done. It's going to save that young couple a lot of $$$$ with all the improvements and the injector upgrade. Not to mention being much safer to operate/ drive.
There is a 1969 conversion single axle down the road from me, I may go check it out today, it is for sale cheap, if it runs, and I can talk my wife into it, I may purchase it, clean it up, maybe do some paint work on it, and try and flip it for some Bus money. Or, who knows, it may be a nice one on the inside, but it has been sitting there for quite some time.
Alot to discover on those machines, nice job. My HD motorcycle mechanic gave me a tip on how to align my rear tire. One 8ft. Neon tube. Think 2 would work for a bus, considering wheel/tire were concentric. Cheers
Not to be mean or anything but I bet if you looked at his headlights they already were halogens...they get that old dim yellowish look when they are old (had a few cars and trucks with them like that) trade em out for LED's and never look back...Its sooo much better...Just remember to aim them correctly...its very annoying to everyone else on the road when you just slap em on and go with no adjustments damn near blinding (no point in putting them on if you just blind the guy coming at you and you get into a head on collision...kinda defeats the whole purpose then doesn't it)
MCI 5C did not come with halogens as far as I can tell. Just the old "Sealed Beam" headlamps. Sealed beams were required on motor vehicles by law until 1983. MFGs could not use anything else until that law was removed. Then they could finally design headlight housings that fit the flow of the vehicle's body, and used halogen replaceable bulbs. That's when we began to see the composite housings specific to each vehicle. Generally, after 1983, when they made a body style change, they got rid of the sealed beams.
@@bills6093 Never meant to imply those were the original headlights as we are talking from the 80's to now thats near 40 years a lot can happen to light from damage to average burn out. If those were the originals damn they got some good mileage out of them. Anyhoo not really a big deal I've driven with sealed beams halogens mostly, even HID on my latest car. I've always figured upgrade the lights if the old ones are not cutting it anymore...My 2k Jeep Tj will be getting the full LED treatment soon as its lights are starting to look dull🙂
@@BusGreaseMonkey Definitely, I guess she is a cute and gorgeous baby!! Your family is beautiful!! Continue to make legency, lot of respect to you, sir!
Atleast they have a known problems list! 🤣 Edit: Yes learn to use your gearing! And jakes if you have them. Down hill/down mountain roads yes you need to do this. In a manual you down shift a gear and let the engine do the breaking work, in a auto this is why you have that 1/2/3 gear avaliable. A big bus (or big rig) use your jake and/or lower gear. 👍
@@DAUNTLESSDIVERS those are everywhere unfortunately ,, i drive a truck a lot and most communities even in iowa have anti jake brake laws ,,this is where having a Caterpillar engine comes in handy ,, because my old peterbilt 359 has a relatively modern 3406E cat engine with a both jacobs engine brakes and a caterpillar brake saver retarder which while not as strong as the jakes it doesn't make the noise ,,the 2 together almost eliminate my using brakes on any hills
Wow great job on this! I wonder, have you ever considered putting down a tape line on the floor like they have in fire stations, to help people align in backing and entering the bays?
You guys do a great job. That 155 temp is really too low. Does it have radiator flaps on it? It takes a minimum of 140 deg water temp for the aids that create in the combustion chamber to not cause pitting on the liners. That's where some of the low power is coming from.
Yeah they are rare. Company I worked for had four that they bought new in 80 and they drove nice. These were 45 pax with no restrooms and 6V71 automatics, not the most powerfulbut adequatefor flat lands. You could also get the 8V71 automatic or the 8V71 4-speed manual. Another company I knew had some for touring and they were 8V71 4-speeds with 38 nice reclining seats and a restroom. Nice little bus.
Has anyone come up with a good cure for the MCI belts of death? The high mounted radiator makes it less than simple to drive then fans without long belts, but....
LEROY! LEROY! LEROY!........Hope this doesnt come off as creepy but we were hoping for another......Karin/LEROY bath time video..(insert smiley face here) maybe next year
I am surprised that a complex heavy duty machine like this MCI relies on one, albeit heavy duty very long belt, to drive two blowers for the cooling system. Can't believe that is robust and reliable. Even some Rolls Royce cars ran a double belt system for some engine driven equipment for redundancy.
In your experience how often we need to change a bus tire ? Only when you see cracks ? Usually truck drivers like to have brand new tires in the front and doesn't matter if the tire is old in the back.
Our fleet runs tires no longer than a 6 year old trie on a steer position, and 10 years as a recap. Of course our steers wear out in just over a year, then they go in for recap trailer or drive positions
Nice coach but those headlights really suck ! You can’t see anything. I remember some sealed beam headlights I had on a Crown Victoria LTD police interceptor and the reflective coating went bad and you couldn’t see sh** with them. Getting older myself and eyes aren’t what they used to be anyway but good headlights makes a difference. Have a Blessed Day
Question, @9:25 shouldn't that long drive belt have an idler pulley to keep it from flapping. Because it looks like it might snap or wear faster. Plus it would limit vibration.
@Arturo Garcia - If the system is still stock, there is an air cylinder that tensions the belt once the coach's air system reaches 80 psi, IIRC. Pulls it nice and snug, no idler needed. MCI built over 10,000 buses with this system - it works.
I just have to ask an obvious question: why is that 6v71 painted in Caterpillar yellow? I drove those engines professionally (for a time). They are all Detroit gray (we always called those driptoits).
I believe it has to do with the bus doing service, in a foreign country. I'm sure Scott or some other followers, will chime in, when they read the comment.
Scott, please inform your viewers how you got into bus repair, and did you go to school for diesels. Your knowledge of all these old buses is just simply amazing. Thank you for making these old rigs much safer running down our highways.
@@BusGreaseMonkey add a flee of boats, some 70 8V71 running all the time, playing in the Dino I can tell you that the 8V71 would jump from 305 hp @ 2300 rpm to 333 hp @ 2300 rpm just by changing from N65 to N70, that's almost a 10% increase right there. they probably got a 15% increase, don't you have to change the restrictor hole size on the return line in the head? By the way, I'm sure you know this but, just trivia, the number 60/65/70 is the cubic millimeter per stroke they inject
And LED is so cheap, why not put cornering lights on, and side lights facing down and back to light up the sides in reverse and whenever else they’re needed.
Depended on the original customer. If the O.C. wanted yellow, DD painted them yellow. Most DD engines that were used in fire engines were painted fire engine red. Was never a fan of Fords, but I do love the Ford blue (and I would paint a DD that color).

I think that was even less than that. I came here looking for this comment.
1/4 revolution

You can learn a ton of things watching this channel. I would pay to have my mechanic film some of the repairs. You got skills and a great team.
Boy….nothing like having your own theme music, too!!!!
We have two awesome songs by tom feller!!

Another great job Scott and team.
impressive outcome! i like the bus you got for your daughter
You may be able to get these older busses for a great price but all the deferred maintenance issues must really add up.
Only thing cheap about a bus is the owner !
Why don’t monsters eat ghosts? They taste like sheet!
😂😂
Good one!
😂🤣👀
Hi Scott,
It was great to see Leroy, if only for a cameo appearance!!
that belt flop is almost comical🤣
at 17:18 your Diesel prices there are almost a buck cheaper then here in the Twin Cities Mn and we have the Midwest refinery just 10 miles away
Great couple always learnin' new stuff when the bus comes in for work.

TO help get rid of the washboard in the road, make yourself a drag that will shave off the ridges and fill the low areas.

You guys should have some led headlights available for their busses I bet you couldn’t keep them in stock
You guys do a great job.

We discussed putting cardboard over part of a radiator in the winter
Love these videos... would love one but I don't think they'd fit down our boreens 🙄 hello from Tipperary Ireland 👍😁
Job Well Done Brotha 💯💯💯
keep the clips coming
I think those MCI-5c are one of my favorite vintage bus, must be rare as h*ck though. Was there an interior tour video Scott?
Yeah they are rare. Company I worked for had four that they bought new in 80 and they drove nice. These were 45 pax with no restrooms and 6V71 automatics, not the most powerfulbut adequatefor flat lands. You could also get the 8V71 automatic or the 8V71 4-speed manual.

Long hair around moving belts is scary.

The high mounted radiator makes it less than simple to drive then fans without long belts, but....
Surprised how cramped it is working on the engines....Skinned knuckle stuff

I vote no on the LED headlights unless you can get them in a warm CCT. Harsh bluish-white LEDs bother me, personally (and other drivers)
I gave up on hating them … there are so many blinding lights coming at me i had to battle back and add led to mine.
@BusGreaseMonkey those are the older LED's that person I referencing to. The new ones don't have the bluish tint anymore.
I am surprised that a complex heavy duty machine like this MCI relies on one, albeit heavy duty very long belt, to drive two blowers for the cooling system. Can't believe that is robust and reliable.

A lot of miles on 5s, 8s and 9s and never a belt issue, well there was that time a mechanic changed the belt and forgot to put air back on. 🤣

We did a tour when they were here last year
How is the inspection and wash pit is coming it will be good improvements

I'll never understand why people put those 'D' model style rear caps on older MCIs. Spoils the look a bit.
Is this one a 35 footer?

What size injector you had/ How much did you increased it? N70 maybe, had always better luck buying Reliabilt
From n60’s to n70’s. That’s a nice hp boost.

Can a person own a bus without a slush fund?
Many live full time in them. No mortgage = bus money
so what was the cause of low power?
Small injectors and some were partially plugged
And plugged up fuel filters and gunk in tank
What amt of boost does it make? Do you think the blower is worn? Do you think there is more power left to be discovered?
What a hideous color to put on a 71 series Detroit Diesel. Either white or alpine green but not yellow. Come on now...
Depended on the original customer. If the O.C. wanted yellow, DD painted them yellow. Most DD engines that were used in fire engines were painted fire engine red. Was never a fan of Fords, but I do love the Ford blue (and I would paint a DD that color).
