I ran a 48A D7E in the eastern Oregon woods back in the early 80's. She had a tilting Balderson dozer and Esco hydraulic boom with 100-inch Esco skidding grapples. I built lots of roads and skidded thousands of logs with her. That 836 cubic inch turbocharged 4-cylinder engine has a sound unlike any other. You can hear them for miles. I still miss that beautiful machine.
Most Caterpillar mechanics of the day would have recognized the D7E engine as 5 3/4" bore, not displacement. You are certainly correct in that you could hear them for miles and they were beautiful machines, especially the late model, last built ones.
The only way to clear land! I used a D7 to clear my 7 acres. If it wasn’t rooted to the core of the earth, it was coming out of the ground. A little back cutting with my excavator around the base of those 100’ pines and ole girl pushed her right over. My friends asked why I rented a D7 to clear my property..I said because the rental company didn’t have a D9 available.
dam rite she's a goldmine!! my bud owne's 2 of these Ole gems and they use them every dam day! to push pumice into train cars and such hell even snow ass deep to a horse!! lol CAT POWER NEVER!! DIES!!!
Most people don't realize those old D7E models had four cylinders engines. When was told for the first time that they were four cylinders I said there was no way. Yes way!
My neighbor has a D7 power shift for sale it looks just like this one , it's been setting for 4or 5 years, he said it has a cracked head, I do some machine work but don't know if I could fix it or not , if I could buy it right I would try it .
Those heads can be repaired. I took mine to a machine shop in Louisville Kentucky called Atlas Machine & Supply. Those heads probably have “spider web” cracks across the precombustion chambers. They make repair plugs for that and the rest can be fixed with Loc N Stitch. Be advised - it won’t be cheap if it’s done right. Mine were $1300.00 per head - and that was 20 years ago.
I've got a D7E just like it up here near Cleburne. 48A1083X. Sure is a good dozer, but I'm looking for some good undercarriage if you know where I might find some.
I get the impression your dad has something against the trees and brush. He's not happy on the mount unless he's taking them out on each dozer run. Not like there isn't plenty of flat land around, but he's got his mission and ritual. LOL.
It was a prototype it had a high horse engine, it was put in a standard transmission. They used that motor after in all of the power shifts. I sure miss it . It was a great starting in very cold weather conditions, did most of my land clearing in winter months.
In strictly Caterpillar jargon, the D7E did not have any other designation. It had many of the same components as a D339. The D339 was categorized as an industrial engine with an SAE numbered flywheel housing, flywheel, fan, radiator, air cleaner, mounting feet. etc.The D339 engine had it's own fuel rack setting, HP and torque rating.
Love the sound of those old cats!👌👌👌👍
Just an awesome sound and video, wish they still sounded like this!
The high horse D7e, best d7 ever made
Love that old machine , sounds great , my dad ran one of these for while

I learned to set chokers behind a D7e in Humboldt County, in the Redwoods...
My 1968 D7E #48A118** is still running smooth.. The army preferred the D7E above them all..🥃😎👌
@@caterpillarman456 yes, 5 3/4 inch bore by an 8 inch stroke.
Ran one a lot love these old tractors.
Like the onboard shot ! Love the low rpm shows the torq !
Same 5.75” pistons as in a 46A- D8H. Just a 4 cylinder instead of 6 (shorter engine block).
The D7E looks like a good all-around dozer
Way under powered compared to the later series.

I had a D7 built alot of ponds with that dozer
It's the perfect sized dozer.

gotta love that broomweed and mesquite!
I've never heard a D7E start on an electric starter before. Ours had a pup motor.
The last of high horse power D7Es before the D7F came out were direct electric start.
My 1968 D7E #48A118** came with the electric starter. It's still running strong today. I wouldn't trade it for two new ones..😎👌
no effort at all for that old girl. she didn't even break out a sweat LOL what a great sound and low rpm.
i know it is kinda randomly asking but do anyone know a good site to stream newly released movies online ?
@Bobby Elian i use FlixZone. You can find it on google =)

Pretty much same engine as the 17 A pistons sleves out of an D8 will fit
@@wilmamcdermott3065 I didn't know that. Thank you. So would that be a 8H piston and sleeves
My dad had one I pushed fat lighterstumps with it for years loved the machine now I have a D 7 G would trade for the 7 E lol

One day you have to do an equipment walk around! Every other video you make there seems to be more eauipment
nice cat that 4 cylinder d8 motor sure sounds different than the g model with the 3306 hahahahahh
the eights are six cylinders

I had a D7E for 26 years ,it had a starting engine ,the big four cylinder engine full rpm was 1200 never let you down ,great machine.
What was it rated at for hp? 150?
180 hp if its a high horse version

They had 160 hp compared to 200 hp with the Gs
power shift ours was a direct drive
This Dozer is not D 7 is D8
where is the 17A whistler haahaaah
Operator does not know how to push brush....just plays with it.
Yes by all means please explain yourself
