Great sound! The early D7s, from the 1T through the 47A and 48A D7Es, ran the same basic engine. It was a four-cylinder version of the big six that powered the 2U and 14A D8s. As Albert mentions, Cat added turbochargers during the production of the 17A series. All of the turbo 4-banger 7s had this distinctive exhaust tone. We logged with them in the woods in Southern Oregon, and you could hear them for miles. Truly,one of the best-sounding engines on earth. The 94N D7F used the Cat 3306 for power. They were easier to service, but were thousands of pounds lighter in the front end than the earlier D7 models. The F-models just didn't have the punch, but were still a pleasure to run. Those were some of the happiest days of my life!
Maybe old but these old 7s have lots of pushing power. There first gear is faster than d6d in second ! Just don't make the mistake double blocking! The blade winch will snap your 5/8 or 1/2 inch cable in the blink of in eye! You will learn 75ft of cable is a real problem and pain to change by yourself ! Still love these old cable dozers with direct drive!
I had two 17A turbo D7D's and one D7F all with stick shift transmissions. The D7F would really push a lot more than the D7D's. They were three great machines. The stick machines would outpush the newer machines going up steep hills.
Be proud of your dad my dad was the same arms like tree trunks and hands like a shovel unfortunately the old boys had it hard and my dad suffers with leukaemia, and COPD from the industry this is when men were men not boys now days try a 7 day week stripping no ear muffs just pure hard work I wish I was born in 60's when non of this government fraud shite changing country making it worse what has happend 😡😒
@@bobbyarnold3536 It should be in the service book for the D7 -C or D 17A seres turbo or natural the wiring is the same the only diff. on the later 17As 1959 or 60 they had a in seat start option, a control tower on the front left floor board that housed the starting controls gas shut off and push button starter and and all the controls to engage the diesel ,some had the glow plug switch.also , they have long rods that go to the carb for throttle and choke control the glass pony gas bowl is mounted inside the tower with a knob to shut it of from the seat . The 17As with the in seat start are very rare. On the 1961 D7E 47A or 48A the in seat start controls for the pony are on the Regular Dash . I have one of each. 1960 D7D w in seat start with cable control # 25 Winch and a 1961 D7E hydraulic blade with the quick drop valves on top of the massive lift pistons to drop the blade fast like a cable control blade. That was because customers complained that the early Hydraulic blade option on the 3Ts and 17As went down to slow. Completely Diff. machines but they both have the big Bore 4. and direct drive trans. The Caterpillar Tractor Co. "Around the Clock Around The World". Never mind Matsu , Beesheee and Kamo-Kazzi'.
That 4 cylinder engine was wide open. It idled at 500 RPM full throttle was around 1150--1200 RPM My D-E-48A will still out work the new "CAT" tin cans. Plus it's ALL PAID FOR !!!

We had one of these on our farm in Southeast Georgia. STRONG piece of equipment.
Ahhhh😌 That sound just makes my heart happy💗 It just takes me back over 35 years when I first got to work a little with one of these! 💘

D7 D one of the best balanced machines engine power to weight ratio
Thats one strong machine!
My Dad was a Master of the Cable lift 7. He probably could have buttered toast with one.
thats a funny image now i wanna see someone try it lol

He ain't running half throttle they turn max at around 900rpm full throttle it's not a bleeding 2023 machine!!!
I own one thats at half throttle they rev higher than that `@@ZombieModz1
Neat machine.
Sounded like it needed to be throttled up a bit in some parts.
for that big old engine that’s wide open
That 4 cylinder engine was wide open. It idled at 500 RPM full throttle was around 1150--1200 RPM
My D-E-48A will still out work the new "CAT" tin cans. Plus it's ALL PAID FOR !!!
it sounds like its idling. I bet those engines last forever
is this in Texas? what part?
Old girl is a little pushy don't you think. Sounds great and looks as if she is not lacking power.
That is badass !
The original Killdozer ! ( from the book by Theodore Sturgeon )
Chris Casteel I believe Kildozer was a D-9
sad part is i emptied the stock room at the shop and i have filters for this old cat
you know what they say, the bigger the boy the bigger the toys
I'll take one of them, or a 977L.
Get it off idle and let her eat. Throttle up.
I think its running at full throttle, max. power was at 1100-1200 rpm
How mainly toys do you have god
how old is that d7?
d turbo in that rel dread
Can someone tell me the weight of the 17A , I've found one I would like to buy but need to know the weight for trucking,
It weighs about 40,000lbs with everything on it.
Sounds makes it scary haha
i was looking for the ram's......nek minute i saw dem cables......id love tah operate 1 ov deez.....
@dalton456 1955
Doing a great injustice to this great machine with a shitty camera.
Get stick back me old!!!
