Resurrecting a GM Bus that had a seized detroit diesel 671 

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.

Dozer1642 people that do not recognize Bubbles are the folk we should be worried about.

Same applies here backside of Wasatch Mountains near last years Dollar Ridge Fires look up Strawberry Pinicals

Curious, what part of Michigan?

Same here. love and admire these beasts from afar.

Ya because that's the way it's done . LOL

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! - Stagecoach Annie

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.

The International 9L V8 comes somewhat close.

Dr Detroit

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's exactly what I was thinking. like how do you haul that shop press around lol

He just bought it and he was learning how to drive it. How many gears was he going to change on the interstate? Hell he was practically in 4th and final gear on the on ramp. We were breaking in the engine which needs to be under heavy constant load not start and stop idling.

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.

@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.

It is a nice place I have been there.

They may leak oil but they'll get back in. . . .

It’s an rv and only requires a regular drivers license.

Still, I'm with Claus. A mature dude, doesn't know what double clutching is...

@@966Mako ignorance is bliss

Who uses a clutch much less double clutches?

@@k2mslskier me lol, all my trucks are manual. Floating gears is fun too 😏

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 . .. . . .

He doesn't strike me as a deep thinker and is used to muddling through. I wonder what he does when changing down for a hill.

oh god help him

Having been both an operator and a mechanic, I agree. I've broken and fixed some anvils, myself. :-)

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!

Boy, does that date us. I tried to teach someone that a few years back. Never gonna happen. Funny thing is, if I get in something with a stick nowadays, I have to consciously stop myself from double clutching. Old habits die hard.

@@The_DuMont_Network Double clutching in modern synchronized transmissions is good too, saves the syncro rings from too much wear.

@@walrustalk indeed. Does no harm, and keeps you in practice.

Tha'ts what I thought too Lol

I've only been driving for 21 years, but when I took my road test I had to double clutch. Do they still have to?

what is it

Thanks

They had problem's but that was mostly due to GM management in the '70s. After Roger Penske bought them, things improved dramatically and I had the opportunity to work with his new management team on making improvements with quality control, something GM didn't really do much of until the Japanese had them for lunch.

​@@siaripop7 Now you have opened a can of worms...... I was Captain of the "Boomer" a custom built Pettigrew 70 foot sportfish built originally in 89 for a famous Newspaper magnate. then sold to some real estate partners, and bought out by one from Las Vegas. He kept the boat in the Dominican republic.. Private yacht. occasionally fished when we could actually run.. Long story short.. 16 V92's.. Balanced and blueprinted by Roger Penske.. Painted red. and sporting Detroit's DDEC electronic controls.. Built especially for that newspaper magnate.. worked for 20 odd years. by the time I was hired... they were a nightmare. almost 30 odd sensors etc. and if one was out... NO GO.. .. Note: The oil Industry used to run those DDEC electronic controls on their oil rig boats.. Big time stuff back when.. Phased out in less than Ten years. WHICH included entire engine and control changes.. $$$$ thanks Roger.. Many boats were scrapped because it cost too much to swap out engines AND controls.. Including private yachts.. lol. I believe she may be the last one.. She is in Lauderdale now and probably is for sale..

Marc Del: And since Penske turned things around for Detroit and then selling it to Mercedes-Benz.....their engines (under Mercedes-Benz) have become downright garbage. Uncle of mine convinced the municipality and County to stop buying any bus or replacement engines with Detroit Diesel. He gets into all the technical stuff of why Mercedes-Benz has ruined Detroit Diesel...something having to do with violating combustion displacement (per cylinder,etc.) and tolerance perimeters which are well known to people that maintain and repair them day in and day out.

The 2-bangerss do have a bark to them!

:) NONE of that modern zero-emissions stuff (Wait..did I hear Greta Thunberg:"How dare you"?) LOL any. the EPA can't touch these old, pre-emissions vehicles (and then therte's the automatic/elctric vs sticks thing...classic trans, those 4-speeds.)

me too

Owning either one of these or a Flxible Starliner is on my Bucket List.

would be better than most women

Sounds like you need a tune up. 7mpg is way low. Or you have a fuel leak.

oh well thanks for the info i've never driven a bus like this before so not really familiar with it it runs really good and starts easily even on 40 degree days ,,i have not had the injectors checked to see if they are working right i do get just a little hint of white smoke and a slight smell of unburned fuel

Only Detroit diesel mechanical 2 strokes. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MZdfIaPlxKg.html

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
