So my friend purchased another fire engine (after selling the Mack a few years ago.) This time it's a 1981 Hahn powered by a 6-71N (inline, naturally aspirated [no turbo]) Detroit Diesel with an Allison MT 644 automatic transmission. Saved from being turned into scrap at the eleventh hour (literally, he picked it up around midnight) this beast lives on!
It's one heck of a rough ride with nothing weighing it down. I had to use youtube's image stabilizer to keep the nausea inducing bounciness under control in the vid. It is also very loud, even in the cab. We had to almost shout to be heard over the roar of the Detroit! I'm hoping to get more videos soon.
This is former Rumson NJ engine no. 275. They removed their station name from the body when they took it out of service.
Detroit 2 stroke and Ally auto. A match made in heaven. Just plant the foot and let the music begin.
Beautiful music 🎶 👌.
I was active in that fire company when that engine came in. It replaced a 1954 American LaFrance 700 series engine. 1981 Hahn, 6-71, Allison HT740 automatic, Hale fire pump. Got to love those 71,s screaming, shifting,and we're doing .......32 MPH. hehe
Guys, as a past owner of two Detroits diesels and the current owner of a Detroit diesel tattoo, all i can say is i adore this truck. My father drove a hahn back in the early 1980s. Thanks for the memories.
Good lord this sounds amazing!! It's a shame stuff like this still ends up in the scrap yard. Your friend rocks for saving it.
TheCRTman has
@@markdonofrio744 Two stroke diesel ..... no better sound :D
Love the sound of that Detroit Diesel!
Daniel Stewart I know right it sounds mean.
Now THAT’S what ALL Fire Engines should sound like!! 😈🔥👍🏾🚒😎
Great sounding 6-71' love that whine sound too.
The best sound on our Hahn was at the right side pump panel, near the exhaust if it had a Donaldson muffler and a big Hale pump flowing big water. That Detroit hammering away, and the whine of the Hale pump was a sound made in heaven!
We had a 75 Hahn with a DD 6-71 natural with a Donaldson muffler married up to a 5-speed manual Spicer trans. A few of us could make that baby talk going down the highway. Foot to the floor until the tach pegged then hit another gear. That babe could talk the talk and walk the walk. Just a simple TCP, 500 water, nice hose bed and a Hale 1000 2 stage pump.
Shit, Id take that Hahn over most of these new showboats out today anyday. She was built to put out fires, not to look pretty, even though she was a great looking 'standard out of the box engine. She was originally painted Chrome Medium Yellow like the Hawaiian rigs, same paint code too. She did look sharp! Groveville Fire Company, Hamilton Twp., Mercer County, NJ E-19-2
You got that right. Today's rigs are nice looking but...
That can put out my house fire any day. I'd be disappointed if a four stroke attended....
Imagine the sound of this racing to a burning house, full throttle, horns and sirens blaring
You probably won't need to use the horn or siren for how loud these monsters are.
I don't have to imagine, I've run our old tanker, 8v92 in a 1982 Spartan pumper tanker, ~2500 gallons on board, ~1500 gpm pump, way underpowered and absolutely gutless but it was fun, got its last hoorah with the onboard cannon, it's been replaced by 2 newer trucks because it had a small electrical fire that caused numerous lasting issues that affected its usability
With a REAL Q nonetheless.
I loved 6 houses from
This firehouse and you knew when this engine was leaving. I’ve ridden in that engine several times as kid. Family friend has been in the FD since the 70s. Always loved that truck. Take care of of it.
Bad ass Hahn. Restore her well and make us all kneel in praise!
The fire department in the city I was raised in purchased six (6) ALF 1972 pumper. One was a hydramatic (?). Man, I could here that diesel a mile away. What a B-E-A-UTIFUL sound.
Love that diesel! You didn't need to look at the gauges when pumping to know your pressure. You knew by the whine.
Love the sound of the screaming Jimmie. A fire truck with a Q2b a set of Groves air horns
Beautiful fire truck and love that Detroit power.
Exactly like a fishbowl I love it!
For those who don't know what a 6L71 is or looks like it's a inline six cylinder Detroit Diesel engine either a N for natural aspirated or TA for turbo aspirated engine that's what a 6L71 Detroit Diesel engine is
TA means turbo&Aftercooled👍
one of my favorite Detroit Diesel vids.
That sweet sound brings back some memories for sure...
Atlantic City fire department used to have a duplex oren fire engine with the 6L71 N natural aspirated Detroit diesel engine with MT 644 or HT 740 Allison automatic transmission until the 2000s
They had these when i was a kid, when a truck drove around you knew it was there. Did I want to be a firefighter, maybee, but i wanted to drive one of those engines! They threw candy at me during christmas time as santa drove by.
Get that exhaust leak fixed. And the passenger is correct...when climbing a grade you'll need to manually downshift the transmission to keep the rev's up around 1800+ RPM. Detroit's don't like to be lugged.
I thought there was an exhaust leak but after searching youtube it seems all 6-71 powered Hahn's sound like this. I still want to get underneath and look anyway. Also, I was the passenger :)
The 6-71 has vertical block, the 6L-71 is mounted horizontally (L = Low).
This sounds amazing!
Wow, I'm looking to buy a 80-82 Hahn!! First one I ever drove was a 74 Hahn Engine. Love these Engines. Looks like you're out by Williamsport.
Ted yellowstone check out some of my videos on my 82 HCP-10.
This video was taken in the Greater Latrobe area.
Hermoso saludos desde chile
Music to my ears!
15psi is normal idle pressure for a Detroit. Tapping the gauge won’t change it 😉
Somehow Hahn trucks never had quite the style that Maxim, Crown, ALF, Mack, Seagrave, or even Ward LaFrance had in their day. if a fire truck is a fire truck to you, I guess it wouldn't matter.
The fire department of my township just sold their old ladder truck with a 6V92T in it gonna miss that thing screaming by
Listen 2 how the driver guns the engine around 3:46
I tried riding the fire truck in sm and it was fun and drew a fire truck.
Sounds godlike! But I've never understood why this and other large vehicles with automatics have such weird shift points / ratios. Seems like some of the ratios are close, and others aren't.
Do you still own this beautiful truck?
I grew up in the neighboring town and could hear this truck a mile away. Do you still own it?
What's the top speed?.
I was told rather emphatically that it will not go faster than 65mph. I believe it too as it hits 2000 rpm in the 50's.
angrodNumenesse The reason I asked is because i know a guy that has a 1975 seagrave pumper that is almost identical to that one and the top speed in his was 62mph and running at a really high rpm.
Iam Your Newest Subscriber Great Videos
Some goo gone Weill help get the sticky crud off the doors etc. unless that is from sanding
Was this fire engine made by the same company that made mowers and tillers back in the late 70's and early 80's?
No. It was built by Hahn Motors which built fire apparatus and busses.
if i was too buy one do i have to get different plates or could i leave the emergency vehicle one one
Devon Edmondson EV plates cannot be used on privately owned vehicles.
OK thank you
Used by a Ex Fire Department In United States.
Listen you how he guns it at around 3:46
I would like to own the old FIRE trucks on the movie Backdraft. Those are the old FIRE engines. I love to own one of those, I would use it for display.
1976 Dark Vator ?
Wow amazing rig! Love that mean roar! Does this truck have a straight pip or a muffler? Does your friend have a fire engine with the Allison HT740 automatic?
There is a muffler but it doesn't do very much. He says he wants to straight pipe it which would be awesome. Also, this one has an Allison MT644 automatic. It's the only one he currently owns.
+angrodNumenesse Does he plan to get another one?
As of right now, I doubt it. Unless he sells this one which is unlikely from the way he has been talking.
The MT644 (MT647 in 1985) could handle up to 325 hp and 975 lb/ft of torque when used in fire trucks!
This kind of stuff reminds why I'm proud to be an American.
What you going to do with this?
teach people with zoom zoom cars what a real engine is!
Detroits aren't naturally aspirated, they have a blower. Just thought you should know. Yes, some did have a turbo, but all of them had blowers.
This is true. However, General Motors decided that since the blower only moved enough air to push a new air charge into the cylinders it didn't qualify as forced induction and therefor the engine is to be considered "naturally aspirated."
@@angrodNumenesse 100% percent correct👍
