Vintage Cummins firing up

[Vaughn MacKenzie]

I was driving home yesterday evening and came across some guy who had just fired up a very old Mack truck. I looked under the hood and the diesel engine chugging away was a Cummins. I looked at the ID tag but it didn't list a model or displacement, but it did have stamped on the ID plate the type of bearings as being "COP-LEAD" . . . whatever that means.

Here's a couple cell phone pics. It had a cool sound, but more like a big gas 6-cylinder (no diesel rattle to speak of). It was rolling some blue smoke but really barked and threw some black smoke when he got on the throttle. Wish I had a video camera!

copper /lead maybe ?

Looks like a old 200 or 220 with a PT Pump, great engines.

I'm reading "The Diesel Odyssey of Clessie Cummins " and have been dreaming of being able to hear his early engines running. I'll bet the sound was amazing.

I agree, probably a 743 cid NH model. If it barked, it probably had a back draft exhaust manifold. Four valves per cylinder even back then!



That engine in a later model with the Roots blower, back draft manifold and 275-320 pump would stand about a foot of fire above the top of the stack when pulling hard. Loved those old Cummins monsters.

Nice clean looking old Mack. Got to have some sound.
Here's a V-8 I would not mine owning. Very cold start.

4 exhaust valves and a blower reminds me of a boat anchor,,,I mean Detroit.

Very cool. In 1976-1978 right out of HS, I worked summers for a contractor that had a 1959 White with a Cummins, a 180 I believe, non-turbo, with a 5 speed main and a 3 speed aux transmission, twin stick, fun to drive, BUT seriously lacking in power with a 40000 pound dozer on the lowboy! We also had a 1956 GMC COE Cannon Ball with DD 6-71 power, I drove both of these during that time frame.

 

[Vaughn MacKenzie]

Yes the exhaust had a bark to it when he hit the throttle.

I googled awhile looking at old Mack trucks and my best estimate on its build date is 1947-1950, most likely 49 or 50.

They only use the truck in the summer to water down a large parking lot at one of the Lampson Crane yards here in Kennewick where they have crane parts.

If you lookup Two Six Bits (nickname) you'll probably find a video of this old Cummins, they definitely had a unique sound!



My favorite Cummins truck engine is the "K" series .



This was one of about six "K's" at the Pleasanton national ATHS show this year.

Good God that is a truck I want to drive!

I would rather drive the ol' Mack especially if it has the two stick quadruplex transmission



That is a cool Pete tho, about a 1960 I would guess. I would also guess that they installed a dog house in order to fit that K series, it is a foot longer then a well rope. OEM was probably a Cummins like the Mack has.

Well Nick that was a Mack I don't remember the vintage though. The K was not the original engine either. I vaguely remember him saying it had a Detroit, either way since it was a long nose hood it fit in there just fine!



Here's a still shot.

Wow it is an old Mack, L-model I think. Early to mid 50's maybe. I did not know Mack made extended hoods in those days but it's gotta be if that K fit. I know the real old Diamond T's of WW2 had super long hoods to fit the 1090 cid Hall Scott 6 cylinder gas engines. After the war they were put into service as on/off highway trucks, mostly in the north west. They used two fuel pumps, 5/8 fuel line and produced 240 hp. Even the Hercules 6 cylinder 895 cid diesel only produced 185 hp in that era.



What other goodies you got

What other goodies you got

Take a look at the Pics in my signature under ATHS Pleasanton. There are some nice trucks in there and that's were these shots came from. .

 

[NIsaacs]

Awesome picture collection. What year/make is that bright yellow chain drive truck? That Cummins is also strange. It looks to be a 200/220 style block with the Roots blower, however the fuel pump is weird as is the intake manifold. It is on the same side as the exhaust.



If you are interested in old stuff, there is a really cool old man in Jerome, AZ. with a huge field of old trucks and crawler tractors. He has about a dozen or more restored vehicles that I find very interesting. I have visited him several times. He has an old sawmill he runs every hour powered by a huge one cylinder diesel engine. He has self guided tours daily or did. He is getting very old.

I can't remember the year of the truck but it's a Sterling. It has a Cummins engine but Sterling must have specified that Cummins use a rotary injection pump instead of their PT pump. The blower is also a stock Cummins item along with that cooled intake. Not many of the old engines that I've seen have that intake but they are around.



It's been quite a few years since I've been to Jerome and don't remember seeing that collection. Is it advertised?

 

[NIsaacs]

I am not sure about any advertising, however he and his collection are amazing! He has a 1990 Dodge W350 dually with a 10,000 lb Dexter tag axle and about an 18 foot flat bed that he hauled most of his stuff with. Some of the real big stuff he drove in or had hauled. The loads he put on that Dodge are unbelievable however he had no reason to lie. He is sooo cool and knows so much about what he has.



One old Dodge truck (restored) has a Hemi with two carbs. I can't remember if they were 2 barrel or 4. It had several unique features and he started it for me. Also he has a restored mid 40's model IHC K11 with an original Cummins, he also fired it up. He is getting really old and is letting his stuff get kinda dirty but still awesome. You can't belive all the goodies he has and the knowledge of everything. I need to go see him again before it is too late.



Truly, he and his huge collection are one of a kind and a must see!!

Sounds good it's on my list
