Oliver 1950 MFWD GM 2-stroke 4-53 diesel

[Clawedbackster]

Sounds GREAT!

[MRcubcadet107]

is that yours?would ya sell it

[smgussey]

@MRcubcadet107 Not mine. I'm sure there's one for sale somewhere...

[IH682D]

2400 stock? Noo that's doesn't sound right at all.

[sidewindermack]

If your tractor is not an Oliver, it's just a wunnabe!

[MrCoolchips]

is it 4X4?

[smgussey]

@MrCoolchips Technically it is called MFWD or Mechanical Front Wheel Drive, some also refer to it as FWA or Front Wheel Assist. Yes it is 4x4 as power is being directed to all four wheels.

[gsxrful]

2 STROKE DIESEL?? GOTTA BE SHITTING ME! LOL

[mobilene]

This is cool. My dad worked for Oliver in quality control, at the South Bend plant, during the years this tractor was in production.

[MrJosephMopar]

what were the rpm's on this?

[smgussey]

@MrJosephMopar Somewhere between 2000 and 2500 rpm I would assume.

[MrJosephMopar]

@smgussey thats what i heard, but i wasnt sure about it! thanks!

[IH682D]

@smgussey bout 2600 is stock. mines at 2800

[671eng]

@IH682D 2400 is stock

[Hetman1974]

Sweet Sound!

[studeystudebaker50]

I had a 1900-4-53---when I chisle plowed---cars would stop on the road just to listen,

[xgi36]

Smooth great running engine.

[peteacher52]

Thanks Smugsey! Your reply to TheMetalCottage about how the diesel 2-stroke works answers something that has been nagging me for a while now. For a 60 year old tractor, that Oliver sounded - and looked - marvellous! Greetings from New Zealand.

[SkatersHeaven771]

that oliver was just a screamin. what was its placing?

[briggs5sboy]

I saw that thing pull at Rollag. It was sweeeeet

[TheMetalCottage]

Interesting...

Thanks for explaining.

[TheMetalCottage]

Suprisingly low smoke. How does it lubricate cylinders? Is diesel fuel thick enough?

[smgussey]

@TheMetalCottage It's a little bit different than a small-engine type 2-stroke you'd find in a weed eater or snowmobile. These have a blower/supercharger to force the air in through a port for intake/compression stroke, and they have exhaust valves for the exhaust/power stroke. So, the crankcase is sealed off from the rest of the engine and is able to be lubricated in the same way a typical 4-stroke engine is - oil pump and splash lubrication.

[possumtail]

Off the dealers lot the 1950T was the only 1950 model that was turbo charged but the engine was the Waukesha 310c.i. not the 4-53 Detroit.

[smgussey]

@possumtail Yes, they made a 1950T and the 1950 was also available with the GM 2-stroke 4-53 diesel.

[BIGblocks4life]

They have a blower because they have no exhaust valves the blower forces the exhaust out. the two strokes need the blower to run but some also have additional turbo(s).

[pupleon]

@BIGblocks4life you mean that they have no INLET VALVES. was only the 51 seris that had no inlet valves AND no exhaust valves

[BIGblocks4life]

@pupleon you're right i did have that ass backwards lol. But yeah sweet motors and fuckin bullet proof!!

[Ladylawless8]

@BIGblocks4life you got that backwards, they have exhaust valves. they do not have intake valves. the ports in the liners are the intake valves. and the silver series ran a blower and a turbo...... i have been building them for years.

[12valvepower1]

chugga chugga chugga

[dking990]

OK for starts yes gm did make 2 stokes they has the 71 series the 53 seires and one other one thats all Gm us to be retard

[ford9572]

Detroit Diesel power KICKS ASS!!! YEEHAA!!!

[cobraman96]

Walk on, big green o!

[hanleyfallsmn56245]

Music to my ears!

[rborneman]

beautiful tractor, love that MFWD, Oliver was way ahead of the competition on that one.

[NeilLB7]

Wish I had that thing to move snow with!! What a hoss!!!!!

[purplehaze743]

that old tractor just rocks, classic case of

irrestable force meets emovable object

guess who wins this one boys !!!!!!

[circlemfarm]

NICE! Like the down shift with the hydra-power and it just keeps walking. The flagman is like "alright enough already, quit showing off!"

[9020powrmax]

The 1950 Oliver was meant to pull anything hooked to it Including the whole forest.. ONE BAD MOTHER EFFER!!

[Slooter3s]

how high is he twisting that 4cyl detroit

[hiyadroogs]

Probably about 2500 rpm. Multi cylindered 2 stroke diesels always sound like they are revving far faster than they are. There was once in the UK a Foden truck, powered by an inline 6 cylinder 2 stroke diesel of 4 litres. Maximum power was developed at 2500, although it sounded like 5000!!

[Kokoots]

They had one, where I worked as a teenager. We called it the screamer. Conversation in it was pointless at anything above tick over! It let go one day and was replaced with a Gardner.

[hiyadroogs]

When you consider though, that the Foden 2 stroke had a capacity of only 4 litres to produce an output of 175 bhp @ only 2500, - compared to a similar power from a 10 litre Gardner 4 stroke, it's not entirely surprisng that they grew a little tired from constantly having their necks wrung! lol

[Kokoots]

It was getting on a bit as well. This was late 70's early 80's. It was also used as a wrecker so it certainly earned it's keep, regularly pulling 32 ton artics and 8 wheelers. Not bad for an ex cement mixer 6 wheeler, made in the 60's. I think it was a 150 Gardner.

[pbgd3]

I believe what he's meaning to say is that the purpose is different. The blower on these engines is just there to provide some pressure to blow the exhaust out and get good fresh air in, with no crank case pressure. A 2 stroke gas engine the fuel and air goes into the case and the piston falling pressurizes it to blow it into the cylinder, on a diesel the fuel is injected during compression, therefore the block has oil, and you need pressure or it would just suck its exhaust back in.

[pbgd3]

To continue my last, if you made the blower on these much more powerful you'd just be wasting engine power, when the blower is forcing the exhaust out of the engine it has basically no back pressure, because the exhaust valve is open, while the intake port is open. So the pressure just blows on through.

[517618294482]

I want one.

[JAROSLAVAGINA]

mean sounding sob!

[neurocytohemotoxic]

DETROIT POWER!

[brent440]

wow, and I thought the 830 John Deere and 1256 IH I grew up on were eardrum wreckers! Pretty strong Oliver!

[91slownotch]

Farmer across the road from me has an old Ollie like that, I love when he has that thing in the field! Sounds great!

[bandit25501]

nice sound!!

[12valvepower1]

slow and steady wins the race

[GoldsLifter]

the supercharger/blower is just to provide enough compression for it to run, isn't for adding power or anything

[Ericattack2]

superchargers and blowers ram air into the cylinders, they do not provide compression.

[JtsGreene]

Wow, ok. Raming air into a cylinder using a blower, supercharger, or a turbo will put more fuel air mixture into the cylinder. With the same bore and stroke you will be compressing more air than without any of the above. It raises the compression.

[dakotamcatee]

the compression is the same no matter what. Just more air is compressed. Diesel use forced induction for more power.

[dakotamcatee]

2 stroke diesels have to have a turbo or supercharger to run

[JtsGreene]

They need a scavenging blower to run, not a turbocharger or supercharger. A roots blower is similar to a supercharger but is gear driven.

[Samqdf]

@JtsGreene huh? a roots blower is a twin screw supercharger

[2strokedetroitdiesel]

Ok so i proved my self wrong after doing the research GM did own detroit in the early years

Now Diamler Chrysler is the Primary stock Holder

[2strokedetroitdiesel]

ok for starters no such thing as a 2 stroke GM diesel!!!! Its a Detroit that GM bought and put in there! Next they are not supercharged! SOme are turboed however! And the Use a blower system called a roots blower to push air through the ports

[smgussey]

A roots type blower is also known as a supercharger, because it has a mechanical drive. It's really just a scavenge pump, but technically speaking it's still a supercharger.

[2strokedetroitdiesel]

THE BLOWER IS GEAR DRIVEN CORRECT?

[smgussey]

I believe so.

[ProudSouthernBoy]

@2strokedetroitdiesel Actually, unless im badly mistaken, blowers are belt driven also. I can see how a gear drive would be practical, such as a situation where a belt wouldn't have enough grip on the pulley to push the intended air.

[pupleon]

@ProudSouthernBoy detroits have a gear driven blower,

[cumminsfan]

@2strokedetroitdiesel yes it is, off the timing gears.

[9020powrmax]

Yes, they are..

[smgussey]

Also, they have "GM" cast into either the block or the blower as I recall...

[Asstacular]

Wow. You clearly don't know a fucking thing.

[ltdann86]

GM never made a 4 stroke all 2 2-71

4,6,871 all the way up to 16-92S

[DionysiosA76]

* all the way up to the 16v149TTA, and 24v71TTTT (looks weird, but in some special configurations people do build quad-turbo V-24 engines : )

[MattytheDem]

@DionysiosA76 like generators and mining trucks

[DionysiosA76]

right... and marine propulsion, although a v16 EMD engine would probally burn less that twin 12v71 jimmys bolted together...

[MattytheDem]

@ltdann86 they also had a 110 and a 149 series as well

[lincolnmetal1]

@2strokedetroitdiesel you are incorrect, detroit diesel WAS gm diesel until the mid 60's. So the description for this video is correct, as it contains an agricultural vehicle made by oliver with a 2 stroke diesel engine made by general motors detroit diesel engine division. The NA version of said engine uses the blower for intake air and exhaust scavinging producing no boost, the T/TA versions use a turbo or turbo and aftercooler to create boost and raise the power rating.

[Deadboots]

@2strokedetroitdiesel

You make no sense. Detroit diesels were GM produced. And yes, that blower is still considered a supercharger. It's pushing more than normal aspiration. Common sense.

[reaper0587]

@2strokedetroitdiesel actually, while it may be a detroit diesel type of engine, it was officially called a GM engine. If you want to see for yourself, find a hart parr magazine of Oliver tractors....and quit complaining

[dryice0002006]

@2strokedetroitdiesel GM owned Detroit thats a well known fact its cast into the engine.

[jacero10]

Oliver was a great product, too bad they got sold out.

[samgeorgianna]

Thats The Meanest Oliver Ive Ever Seen!!!! That 4-53 Is Turbocharged Right??? It Sounds Like It

[smgussey]

I'm not sure if this one has a turbo or not... but all the GM 2-stroke diesels have a supercharger on them, that's where a lot of the screaming noise comes from!

[Xx69roadrunnerxX]

Old GM 2-stroke diesels have superchargers to get enough air to the engine right? Not to provide boost right? That what I have hear, but never gotten a direct answer.

[smgussey]

I don't think there is much if any positive manifold pressure from the supercharger on these. I couldn't tell you for sure, though. Since it is a 2-stroke engine it needs some type of scavenging, most use the crankcase as the scavenge pump (snowmobiles, chainsaws, etc.) but these have the supercharger.

[Xx69roadrunnerxX]

Cool, thanks for the info!

[1466puller]

the GM diesel have blowers insted of turbochargers,theres guys that i pull with that pull GM diesels

[DionysiosA76]

a non turbocharged detroit is considered a N/A engine, although they still have the blowers

[oliver1950gmpuller]

This 1950 is not turbocharged. You can tell by the sound of the motor. Check out my video response of my 1950 puller. Mine does have a turbo.

[Hotrodx199]

thats a good sounding 4-53 detroit

[B422TMack]

lil 453 Screamin jimmy sounds sweet olivers are rare here in West Tn
