It is really fabulous that so many people are donating their time, effort and $$$ to help save the old buses. I hope the younger generations appreciate these buses in the future. There are still two heads needed for the other engines.
It is refreshing to see how this group is willing to help. The volunteers and sharing parts is amazing. The unselfish way each member gives and shares with others. Unbelievable
Me too, and not just me here in the UK.. we never had Detroit diesel busses here, so very new for us older guys.. Did remember someone saying over here so many years ago - "why do American buses drive In low gear all the time" - LOL we now know why - 2 stroke diesels sound like there revving hard but only doing modest revolutions.. We did once have some lorries that were 2 stroke diesels, COMMER done one with its "blower"
Phil just cracks me up. I'm sure it has been a wonderful time with him and all the stories I'm sure he can tell. Nice to see all the volunteers there to help. Really enjoy your videos.
Fantastic update. That head is traveling close to 1,100 miles? (Very bus-like when you think about it) Well done to the sender, the courier, and everyone else that is helping! We say this counts as an American Thanksgiving story.
The vintage bus community is amazing. A big Attaboy to Bob and Tom, and especially Jay for donating the head, and Lee for driving 800 miles to get it to Phil and Scott. You guys rock!
Seen your helper use a hook to clean out the piston groves.....ouch! I have always used a piece of a broken ring with a chisel edge ground on one end and wrap the other end with tape. Wont damage the grove.
Hi Alan, you beat me to it on that one,lol, I used the same trick when the old rings were scrap, it sure was hard on the hand's after a few pistons, not my favourite job, Best wishes Stuart.
LOVING EVERY MINUTE OF THESE VIDEOS...... and I laugh at your occasional, actually frequent CHUCKLE...We can tell you enjoy your work, because it makes you happy. Well done, keep going....Save History.
I have to say Tom. did an excellent job of fitting those liners.. I can see him having his own show one day... very astute... and sorry some assholes ruined seeing more than Kelly's feet. But we Fans... know she's there... And.. the very 1st. charter boat I worked on... a 1928 Mathis Trumpy Yacht... in 1971.. had two 671's... I cut my teeth, learning about diesels on them... we kept runaway boards close by.. Also the Military made millions of them.. so there are plenty of heads still..
Scott, I'd recommend you with a laundry marker number each tool to make sure you don't forget one at a job site. If your like many mechanics I've known over my lifetime tools are unintentionally scattered all over the job site when you finish and can take up to 3-4 hours to put everything properly away. I just had my 2005 Jeep Grand Cherokee limited serviced and when I opened the hood this morning to check fluid levels sitting on top of the air box was an expensive Snapon 1/2 ratchet. Stopped back by his shop and when I walked in I asked, missing something? Holding up the ratchet. I was wondering where that got to he replied, I was just about to order a new one. Thanks to you and yours for the beautiful work you two do and the videos you produce. I especially liked the put together videos of the MCI 5A you put together in a 2 plus hour video. And thank the gentleman from Tennessee for the story on Bud one and the description of " is this how people rode in buses? " story. Hilarious, I just about fell off my chair with his description of how he felt every little defect in the road and then it took off and flew and I discovered what air ride on a bus is like. But what really began to fly was BGM. Cheers!
I loved watching everyone working together for a common goal. I do have a suggestion though. When installing the pistons and liners. I would put a short peace of hose on each one of the studs on the pistons. That way when you are guiding them on the the crank they are less likely to mar the crankshaft journals. Love your channel Scott you do a good job.
@@philepstein524 YOU KNOW I was teasing you , My dad would always wipe down things that most of us didnt care or notice , You guys are out of a better stock , God bless you .
Well if he left Lexington at noon doing 60mph average he should be there by 4:00am assuming he only stops for fuel ! Lol. My high school math teacher said it might come in handy ! And he gains an hour coming west ! Lol. I’m glad someone had one for you .
I was just wondering, if like me you buy a pair of glasses at the pound store/ dollar store. I got glasses all over the house, and sometimes I still can find a pair.
@@TOMAS-lh4er Not so much on these engines because the crank surface is so hard . And you often have a mate underneath to guide the big end onto the crank . On the EMD's we used a crane to fit each liner/piston set.
Coming along nicely guys.. Saw you using LUCAS product, I too use LUCAS products when I can here In the UK.. I have a Ford Mondeo 2 litre petrol auto thats got a suffering auto box, it sometimes loses drive In drive 1, so, drained out 1 litre, and pre heated a LUCAS autotrans fix bottle and put that in the trans - made it better but not cured. ran it 4 months then drain out another litre and put another liter/ bottle of LUCAS autotrans fix.. The cars still not perfect in Drive 1 and drive 2 but good on drive 3 upwards.. The mondeo is still going so not scrapping it yet.. Still shiny comfortable but very high millage, NOT DEAD YET - lol Thanks LUCAS OILS
From Corbin ky to Minnesota state line is 850 miles abt 13 hours of straight driving , a bucket of KFC chicken from Corbin ky would be belly aching , butt hole squirting deliciously rotten!!
How about when installing the piston & liner first install the liner with the rod 90 degrees to the air box to avoid jamming the rod into the air box ports , after clearing the box with the rod then rotate the liner 90 degrees back to line up with the crankshaft and drop the liner in the rest of the way ?
I used 2 rubber hose's stuck on the rod bearing cap bolts to keep the rod lined up with the crankshaft. The rubber will not scratch the crankshaft as it slides down when pushing the Piston down. Then just pull the hose's off and bolt on the cap.
Any idea Scott how old the engine is? Just fascinating to think after sitting outside for years she's coming back to life. Wish I was there. Just for an example it's big brother the EMD 645 as an example cylinder liner, piston and connecting rod and cylinder head checks in at around 900 pounds and is installed as a complete unit. This requires an overhead crane or hoist. cylinder head torque settings utilise a torque multiplier and if I remember correctly finish somewhere around 965 pounds of torque.
You are a nice person and a mechanical genius, the bus whisperer, that is why people are willing to donate their time and energy to this cause. Also, a question, What is the purpose of the blower?
The blower scavengers air at just slightly above the static air pressure about 1 1/2 pound of pressure and is used to force out the exhaust while providing a fresh charge of air for the injector to inject fuel into, remember it all happens on one revolution of the engine. The blower is needed or the engine won't run but doesn't increase power like a roots blower does for a gas engine.
Looking forward to it. Love warm Florida weather. Talked about moving to Lakeland, my favorite part of FL. Oh well, Minnesota winters aren't that bad and I can't leave this fantastic gig I have here permanently.
@@philepstein524 You can swing 500$ (land rent) a month and 15/20,000 for a used double wide in a little gated retirement community you can get out of dodge for the worse 3 months a year. By law the double wides have to be less than 12 year old. I just sold my late moms for 22,000 and it was 6 years old. The parks have all the the amenities.
Always thought that a steam clean before working in the engine area would be on the cards, why is it it's not done? Perhaps the owners would do this before you started Scott?
Scott have u seen a oem detriot ring compressor? It’s a cylinder that tapers down to compress the rings. It works slick, I cut my teeth working on 2 stroke Detroit’s 23 years ago.
Scott, what is the horizontal cylinder off the right side of the oil cooler housing? I assume the vertical one off the left side is the cartridge type oil filter?
Is it very common to do all this work and not remove the engine? Or do you only pull the engine with catastrophic damage that renders the engine non rebuildable?
There is a tool that installs on top of a new liner that allows the mechanic to easily slide the piston/rod assembly's very easily to the new liners. The tool is wider than the new liners making it easy to squeeze the new rings into the new liners. Takes less than a minute to insert the piston and rod per cylinder.
We are working on a budget. There was nothing wrong with the pistons so no reason not to reuse them. $400 saved here are there really help out a lot. Getting the bus into running condition and not smoking is the goal. We have a lot of old used parts here in the inventory. Fixing it like it was meant to be fixed back in the day. There is a whole chapter in the book about reusing old pistons.
Chris Smith on cats you do called a power pack liner and piston assembly together guess for less chance of mechanics messing up with the piston rings is my guess
Richard Van Dyke Detroit Diesel pistons load from the bottom of the liner so the oil rings are not broken by installing from the top of the liner the bottom of the liner has a small chamfer for that purpose
On a Detroit it's a blower. It literally just blows air into the combustion chamber. The motor could not take in enough air on it's own. When you put it on a gas engine it becomes a "super charger" because then it creates boost. Same thing different concepts.
Right. The blower does not pressurize the intake cycle much above atmospheric pressure, which is why it is not referred to as a supercharger. It’s primary function is to supply air pressure to push out the exhaust gases and help induct the intake air.
