- This was a fun project from November 2018 in Benson AZ. This GM Bus 3751 silversides 1947 had an over heated engine that was DOA. We brought it back to life and the owner drove it 2000+ miles home after the rebuild we did in a dirt lot. Traveling vintage bus mechanic. Bus Grease Monkey.
Scott, you’re a God send to these bus owners. Without you’re expertise they would surely be screwed by the general bus repair shops. May god bless you and keep you safe in what you do.
i drove a 318 detroit for years. it had a 13 speed fuller road ranger shifter. the only time i used the clutch was for stopping and starting and on low speed sharp turns when there might be a bind on the drive train. i did NOT ever grind the gears and the mechanics were amazed that they didnt have to adjust the clutch or replace it.
Ya because that's the way it's done . LOL
Dude, seriously, you are my hero. No joke.
That bus was dead in the water in the middle of the desert with no reason to believe it would ever move under its own power again.
The southwest desert doesn’t give second chances, but you came into town fully equipped to breathe life into this badly abused bus and it is just one of your many videos of this kind of shenanigans.
If you ever find yourself in the central Sierra Nevada mountains I sure would like to feed you a few beers, fill your tanks and share some stories.
You can trust this guy. He has Bubbles as his avatar.
Brad Leonard so many people think it’s actually me.
Bubbles is much more handsome.

Same applies here backside of Wasatch Mountains near last years Dollar Ridge Fires look up Strawberry Pinicals
Curious, what part of Michigan?
It's great when you see someone in 2019 working on a 1947 bus like he was a Greyhound tech in the 40's. I hope there will always be people around like this man. And, I hope the owner of this '47 learns how to down shift as well. A whole different thing !
I hope he learns where the brake pedal is so he doesn't have to look for it before pressing it.
In UK we have to pass a test which includes shifting up and down and generally knowing how to drive.
Nice bus. I can't believe you rebuilt the engine in the dirt, in the middle of NO-WHERE!!!! Thank's for sharing.
When I'm not working I swear I can watch this 24-7 I know shit about shit that I never knew I needed to know??? Thank you you-Tube and Thank you America. Three weeks of this kind of vids and I'm practically a Diesel mechanic. Yester day learning about KT3406E Cats and Acert heads & crank and today this 😁 not complaining....
SWEET sound, always loved hearing them as a child and the air brakes, AND you taught him the correct way to shift !!!
Amazing how much better it shifts when you do it right!
Still did a good job handling that big girl.
Double the clutch!
I used to sleep on the back three seats while waiting for my groups to come back (yes, I did fit!) and if it was cold, I'd idle the engine and sack out. It was like listening to a cat purr and I'd go out like a light. It got to the point that I would know when the engine was the tiniest bit out of timing. The mechanics thought I was nuts, but they checked it out & I was right. I miss my old girls soo much!

That sound never gets old.
The International 9L V8 comes somewhat close.
Pretty bad ass. It's amazing how you can bring these old buses back to life.
Dr Detroit
Glad to see that someone still knows how to fix Detroits , Drove lot's of trucks with them until emissions standards changed . Still love them !
Work others are incapable of in a well fitted out garage, yet this was done at the side of railway tracks. Hats off to you Sir !!!
Its amazing that you travel so many miles to save these pieces of history working outside in the elements lying in the dirt or gravel whatever the circumstances are dealt you. Most mechanics work in well lit shops with lifts and air conditioning yet you get out there in it all with oil dripping on you and breathe life into these wonderful artifacts. You sir are very special.....I hope your hourly rate is double shop rate. Those garage pussies can't hold a candle to you. Way to go!
I swear that old bus is smiling take a close look at it lol you did a wonderful job young man
Something about these old buses! The lines, the curves, they are works of art!
Nothing like a good mechanic that can bring a dead engine back to life in the field. Believe me, they are the best thing when you are broke down beside the road.
Scott this was the first video I remember of you and the broken bus. Look how far you come since then! Many thanks for all the memories.
I offsided for a few years on an Ingersol-Rand T3 drilling rig converted for water well drilling, 6/71 naturally aspirated truck motor 12V71 twin turbo deck motor. Over the years, we had a number of roadside and job site repairs, including replacing heads and a complete deck engine swap onsite - we couldn’t move as we were stuck down the hole with no means of getting out. The 12V is a big lump of metal to handle on a steep drilling site. The owner had a shed full of spare engines as a source of spares, often not a great option but we kept the old girl running and making money. A steep learning curve for two non mechanics - we did have a very talented and experienced fitter looking over our shoulders, and testimony to the clever design of the line of engines.
Having spent 27 years at a Freightliner dealership I always tell others when changing oil never rely on the dip stick alone all ways know your. Capacities
Verify your dip sticks low mark high mark full capacity
That engine sounds like it is purring. Very sweet.
Some people can break anvils, glad you are around to fix them.
Having been both an operator and a mechanic, I agree. I've broken and fixed some anvils, myself. :-)
When I went to the Diesel Institute of America in Tampa our final test was to pair into teams, remove a Tampa city bus engine, rebuild it, reinstall it, and if it ran well without issues, we passed. Well, we passed. The liners were worn, so we pulled the head, pulled the oil pan, pulled all of the rods and pistons, replaced all of the liners, reinstalled the pistons and rods, reinstalled everything else, primed the oil system, primed the fuel system, and she fired right up. It was the first and only Detroit I have ever worked on. It ran like a top though. I miss that beautiful sound though.
@Terry Melvin Especially the 6-71 inline engine the 6V and 8V engines don't sound the same.
@Terry Melvin I used to listen for the last bus of the night around midnight as it rounded the corner behind our apartment windows it usually had an old look bus with a 6-71 inline it had a nicer sound than the newer fishbowls which had 8V-71s.
Used to work for a township that had Oshkosh snow plows with V- plows and wing plows on both sides to keep Rt 11 open ( two of the three ) They had 8V92's in them and we'd load them with #1 A crushed blue stone . . . . . . .I couldn't wait for the first snows to fly just to hear those monsters in full song ! ! ! If you don't know they used turbos to feed the superchargers . . . . all ten wheel drive with Allison automatics . I remember in '77' we had a record snow fall and the snow depth was ridiculous everywhere . Keeping the main roads clear left many secondary roads on the back burner to clear when we could . I recall the snow coming over the V plow and both wings . All you had to do is push on the throttle and that Detroit would scream and the snow would fly . We had a push pole hooked to the rear on one road which had a 12N Cat road grader connected to the other end . Not to assist in pushing actually he stayed in neutral and we dragged it on top of pushing snow . But the ditches being deep and on occasion going into them the grader would assist in pulling the truck back out . Yeah , will never forget that sound . .
addium Uppicus the Blizzard of ‘77, I remember it so very well. It’s the most snow I’ve ever seen in my life. I was in Ohio at the time and I remember those same style plows hooked to the road graders that came thru a week after the blizzard. That’s how long it took to get to some areas.
Robert, my story is similar to yours. I graduated from Cal-Diesel school in '79 where we learned to work on Cummins and Detroit diesels. Loved everything about Detroits but after graduation I never worked on another. Always regretted it.
MAN! There is nothing like the sound of a 2 stroke diesel :)
MAN you Sir,... are not kidding. I was "introduced" to the 671s assigned "eighteen month / Shore Duty Billet" for 'C' School, Great Lakes. on.. Detroit Diesel,.. Cat.. and Fairbank-Morse (opposed-piston): That's a whole lot a schoolin in eighteen months... and that's a "no shitter". How about their "hunt",.. that's just tougher than wood-pecker lips!!! Thanks man!
Been watching your videos for about 2 weeks now - I have total respect for anyone that really knows their field and you definitely know yours 👍 Just Subscribed. BTW, I don’t own a bus and probably never will, but your videos are very informative and enjoyable to watch.
Same here. love and admire these beasts from afar.

It is a nice place I have been there.
You're an amazing diesel mechanic. You did things I don't think anyone else would be able to do or have the guts to do..
Terry Melvin
And he has only been doing this for 8 years from being a photographer. You would think he has been doing this forever, amazing work.
really glad to see you helping save these old pieces of art... some are beyond repair but it's nice to see people care about old iron.... they don't make stuff like this anymore...... unfortunately..... that bus needs a lot of work.... hopefully the owner does it right!!!
Great video!!
This reminds me of the days I worked on Detroit's back in the mid 70's. One year out of high school I went to work for Stewart & Stevenson in Houston working in the truck shop. I was the new kid so I got all the nasty work on garbage trucks, buses and oil field trucks.
The 6-71 was a workhorse and was fun to work on. Many trucks had oil dip sticks that were either marked too high or too low. Even brand new trucks from Peterbuilt or Kenworth were checked.
My favorite bus to work on was owned by Mickey Gilley. Every winter they would bring it in to have injectors changed from 55's to 65's. If we left the 65's in all year it would overheat in summer. Not enough room to put a bigger radiator back there.
Wow that was real lucky to survive without ceasing and burning.
Love the Chanel , I hope you educated him on the extreme importance of watching the temp gauge and SHUTTING it down when hot
You know its really Surprising how many Drivers don't know about Double de Clutching on heavy Engines she Sounds really Good Nice Job
Yes "double de clutching" !!! must be done on old vehicles that don't have sync-mesh gear boxes !
Year's ago I had an old land-rover POS! ... straight cut 1st gear and helical cut 2nd gear that were non sync ... however 3rd + 4th gears were.
why use the clutch if you know how to shift
@@CharlieBrown-pb9xn Are you talking about modern "syncromesh" gearboxes ?
Straight cut gear > "old school" crash boxes ? or constant mesh full size truck gearboxes ?
I doubt that you know what your talking about 🙃
I dont know how their made or how their cut but in the many 18wheelers ive driven no clutch except for taking off works good
@@CharlieBrown-pb9xn , I took my drivers test in a '54' Mack B series with triple sticks , and you had to hook your arm through the steering wheel to shift the high-low with the main box to keep the rpm's right , and double clutch for each gear as they weren't synchromesh anything . Also unless you were very skilled and you should miss a gear you stopped and started all over again . In the mountains where I grew up that wasn't an option especially when the roads are covered with snow and ice . Just saying , and watching ' Ice road truckers ' I just shake my head and say spoiled whiners . We used to run the St Lawrence river when it froze and never gave it a second thought . Now when that little metal arm would fall as you came off a mountain . . . . . . . . . =- / . LOL! Old timers on here will understand . .. . . .
Wow, that is grit right there....Rebuilding an ending inside a bus, laying in the dirt with no shop...CRAZY, but awesome!
That start was smooth AF. Incredible revival. Sounds like new!
Know nothing about buses but have enjoyed finding your channel. Thanks for the night time entertainment
Dude you Rock as a Bus Mechanic. Like a Bus Whisperer Cherry work for these Clients,👍
Field fix of the year!!!
Awesome job. 😎👍🏆🍺
Double clutching = good idea to avoid grinding gears. Clutch replacement is easier and cheaper than transmission replacement. Really love these old Detroits, probably my favorite diesel brand. Your channel is excellent because we all learn how these engines are built, and how they function.
Another thing I love about detroits, if the cylinder walls are damaged just replace the liners. Great design
@Will Will that's how I was taught to drive a non synchronized transmission. Truck was an old L9000 with an 8v-71 Detroit diesel. I swear it was like that trans didn't like me, until after a few days I got the hang of how to shift it without grinding gears. Made me realize how thankful I am that manual trans are usually synchronized nowadays. I'm still glad I learned
That Bus has been all over America.. And still running....
halo is awesome, master chief
Really cool video .your spanner skills and dedication are a credit to you sir,you saved that old buses life.
I heard your song this morning, I LOVE IT , YOU have become a wonderful person , I am Great full to SEE what you done , it shows that mankind is still here , Thank You !
Nice video. Great to see there are still professionals who know how to keep the old Detroits alive!
What a huge job! Imaging if that block had to come out! Replaceable cylinder liners are a gift... Awesome effort!
The sound reminds me of the GM New Look city buses I rode as a kid....great memories
Detroit Diesels are the best engine ever. Reliability wise at least. Other then that they're a mistake. But I love them. I've been lucky to have them in my life since I was born. A 353 was the first engine I built with my dad. Thank you for taking the time to restore this, it warms my heart.
Idk why I'm so emotional attachment to every Detroit ever but I am. They're just do unique and sound amazing
A long time ago, in a place far, far away, I used to be a heavy equipment mechanic. Watching this brought back memories! :) Excellent video and keep them coming.
I love those old buses, it would be great to restore one as an RV.
You sir are a rare breed not a lot of people know a lot about Detroit's anymore
RUclips just randomly showed me this video. Little did I know I would recognize the mechanic as someone from my childhood. Well done sir.
Hey Joey Coates!!
Hello. Love the channel.
you are a true master of your craft, to get that thing going in a dirt field then drive it a couple THOUSAND miles is impressive.
What can I say mate you're the real deal, skilled as a skilled thing. Make sure you pass the knowledge on.
Now that’s what I’m saying ! These pieces of history and art are brought back to life all because someone cared enough to do so ! I realize you can’t do that to every piece of equipment but on some they have valuable parts to make others live ! From now on I’m calling you the DIESEL WHISPERER ! Lol
I met a guy that was a WWII veteran and he converted one like this into a motor home and cruised the country back in 1981. He said it got 10 mpg, back when diesel was cheap.
There are few sounds as pleasing to me as the sound of an old school diesel at tickover. Gorgeous ❤
Spent 23 years US Army there were so many Detroits from 3 cyl to 24 blowers turbos multiple blowers with multiple turbos just has it's own sound WOW God Bless You and all that You Do what a sweet sound second only for me to a Huey
Im So enjoying all of your You tube Videos.. I love these Buses My Son went to WyoTech .. His career since has treated him well..
Those old rigs are so dang cool! Kudos to you for helping keep it going.
my father was a diesel mechanic in the airforce i would give anything to know what he knows i love those engines and how they work ,, i wound up doing collission repair on cars for 40 years but those engines were always amazing to me ,, thanks for sharing another awesome video !!!!
This is close to my home town of Sierra Vista. I caught a glimpse of the Hauchuca mountains
Drove a Pacific logging truck with a 12 cyl Detroit. Called it the buzzin dozen.
And you've worked another miracle... love these videos.
The deserts of New Mexico and Arizona. Beautiful and deadly!!
Man, she sure sounds fine. Beautiful. Well done, Scott. I just moved in to an apartment complex. I was allowed to look at the backup generator set for the complex. Lo and behold I was greeted by a 20v149. It is freaking MASSIVE and sounds just as massive! I'd never seen something that big as far as an engine. I have a pretty good size extended chassis Ford E250 cargo van and I swear that the engine is longer and taller than it!!!
Can you say, Money pit? Love it, but glad it's not mine!!!
You are amazing! So enjoy what you do, your passion! Thank you for sharing your story. Thank you to the community of Bus lovers!!! There truly magnificent. 💯 ❤️ 😘
good for you sir for cleaning up your mess and not leaving it for the storage units to clean up
I'm an auto mechanic by trade, found these bus videos by accident and now I'm addicted! I wanna resurrect one now haha!
I've just found him a couple of day's ago, and now I'm thinking hey wouldn't that be great to rebuild one (a bus) & just drive into the sunset, or sunrise.
Thank you guys for saving the silver wings!!!Those Busses are absolutely Beautiful!!!
Just torquing the rods and mains on these engines is difficult enough on a concrete garage floor. Much respect for what you do, my friend!
Loved the double clutch lesson. Brought back the late Sixties for me when I never had a car with functioning synchronizers. I knew I was the only one who could drive my car and not look the cave man. Nobody touched my '63 Stingray.
Watching your videos makes me want to go find an old bus, they seem to be made up of a bunch of ingenious systems all wrapped up in a beautiful package... but I’ve already got enough car and motorcycle projects to keep me busy for a long time.
watching his videos made me finally drop the hammer and buy a bus of my own ,, I bought a 1948 PD-3751 silversides
after looking for years trying to find a PD-4501 scenicruiser that wasn't junk
it was previously restored in the early 1970s as an RV ,,i have left the 45 year old retro styling and updated the electrical systems and all of the plumbing and heating systems ,,which has proved to be a serious undertaking
never did understand why someone installed a gasoline generator in a diesel bus ,but that got replaced too with a Dual 6500 watt APU system ,along wit ha whole lot of other new technology
So awesome!
I spent a LOT of time behind the wheel of a '60s GMC buffalo 871.
I miss that weird turn table feeling you get steering one of these buses around.
Plus shifting based off of seat of pants vibration.
Once in awhile I could get a butter smooth shift. Normally I had a little grr grr grr shifting in.
excellent work. good thing you got it out of benson before it got really hot. i spent quite a bit of time there and summers are nearly unbearable. first start sounded good and it just got better from there. thanks much for posting and +1 for resurrecting vintage gear.
Remember the Grey Rabbit or The Green Tortoise Bus Line use to Go From NY to San Fran....I could set up a Cot and Sleep like a Baby to the Sound of that Engine 🤙🏻✌🏻😴
What an amazing project you chose to tackle. Kudos to you.
One very lucky old 2 stroker to have an ace like you heal all it's woes. Good job.
Wow! This is the first time that I have ever seen a bus with a column-mounted shifter. I never knew that sort of setup existed. By the way that Detroit Diesel sounds nice. The sound of a "Screaming Jimmy" is music to my ears.
Knowledge and talent great job roadside engine rebuild
You must have a well stocked set of tools and equipment on your bus to do a field overhaul of a 671. Impressive bit of work sir! Thanks for the videos. Short as some may be, they are all entertaining and informative. I've learned a lot and perhaps someday when I retire I'll get an old GM bus conversion to travel the country in.
That's exactly what I was thinking. like how do you haul that shop press around lol
I had a 49 Silverside, my sister stole it and the paperwork, it was last parked in Port Townsend, Washington. That was many years ago. It was a pretty good conversion. I'd like to get it back.
My dad had a GM bus back in the day. Those engines had a sound all of their own. Good job. Porter Productions.....
I love the sound of the old two strokers. Worked on many at the local diesel shop in Holland Mi. Van ECk diesel service. I can rebuild the head on that thing with my eyes closed. 238's were tough. 65's should get ya upta 250 to 265 H.P. Keep her running for the next generation....so they get to hear the music from that Detroit sir.
Beautiful iconic vehicles. Well done for rescuing this one !
People when you buy an old vehicle you have to base line it. That means you assume nothing. So you find out how much oil and liquid each system needs so you know for example the gearbox has the correct clean oil of correct amount and factory specification. It will take time but it's fun too. And you will know your transaxle bearings are okay, the engine is right steering linkages safe and correct. Otherwise just don't play. But I take my hat off to these mechanics. You are unbelievably awesome. Replacing cylinder liners like that wow! Great video. Thanks for sharing.
Beautiful buses, I love the sound of these engines.Expected stik shift not column shift on bus
You are one talented man - I enjoy your videos! People just don't have these skills anymore!
That engine sounded so SWEET Scott!!! Awesome work!
That bus sounds smooth. I would love to see it freshen up and on the road thank you for making the video bring em back to life ☺
Now that's a dream, I have always wanted to build a home/bus. I'll poobably end up restoring/remodeling a travel trailer, thunk a bus might be a bit much for me since beating lung cancer, just not a 100% guy anymore but I sure have the dream of traveling, maybe a step van into a road home? Lol, its all good, gonna chase this dream.....
I love these old buses. The design is so cooool.
Great bus rescue, that engine runs very nice. Keep those buses rolling, New Sub from New Zealand.
Thanks
Impressive work, sir! Nothing like the sound of that first firing up after a long time laying around. Has to be music to your ears.
Dude your super smart on mechanics love your videos.
Fished old 48' wood boat a Detroit v71 work 4am to 8 pm then climb in a bunk forward of engin room engin heat and rocking ocean soaking wet slept like a baby on way into port 3-4 hours. That engin kept us. Alive Pacific Ocean 1970's
They may leak oil but they'll get back in. . . .
No computer gizmos , just knowledge , skill and born with smarts, buy that man a beer !!
Now I know how to double clutch, no idea what to do with that info, but I do... thanks for the video
@Copperhead Sutton all heavy trucks with non synchronized transmissions are shifted that way (but most of us shift them without a clutch ) generally a 400 rpm split will get you into the next gear.
The whole double clutch work thing around the 16 minute mark really reminds me that bus and truck drivers are really professionals in their own field. In the military, I drove 10 tons with alli automatics right up till I was stationed in Turkey, where we had 10 tons with 17 speed roadster manuals. I was the 18 year MSgt who had no idea how to double clutch and I looked like a 12 to those guys.
Really enjoy watching your channel.Hello from the UK.
You are so good on the GMs te screaming demand
In the interest of fairness- I'm really not into buses...or diesels...but I'm a new subscriber to your channel! Googling the DD engines turned up some fascinating info - what an incredible design they are! Two-strokes - who knew! The fact that the engine took such abuse (low oil) is amazing. One wonders how long the engine would have continued running with basically no oil if it hadn't puked out all its coolant? The fact that it was rebuildable in a dirt lot is doubly-amazing.
You guys did an awesome job - that engine sure runs smoothly! Me, I probably would've gotten there, seen all the damage to the eingine, thrown up my hands and said, "Screw it, it ain't EVER gonna run again - let it rot." and walked (ran) away. Kudos to you guys for not getting discouraged and doing the nearly-impossible.
Great video :)
This is a cool channel. I knew nothing about these old buses. I like things with motors and things that are vintage. Now I like old buses too :) Thanks for the great content. I'm impressed with your knowledge of all things bus related!
Excellent video. Really enjoyed it.
Nice double clutch tutorial !!! I love the engine sound
