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!
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.
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.
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.
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 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.
