What is the rear ratio that is in it now and what is your rpm when your at 55 mph? 

RPM is about (might be a little higher) 2400 full-load, 2550 unloaded, and the rear end is a 6.86. I think the 80 mph truck had a 5.63, but for some reason some literature suggests it was changed back for the 6.86 before completion. I think the 5.63 was on the truck when the fire company owned it because it was said to do 80... this all with 10.00/20 size balloon tires according to other literature...

This is the further info I have...

I’m 30 miles south of Cleveland Oh.   I just posted it here on bigmacktrucks. I’m hoping to get around $19,000 for it it’s in really good condition.   I also have a 62 L model that’s really solid if you’re interested I can send you some info 

Do you mean a 52 L model? Regardless feel free to post pictures of that too!

My favorite horns in all aspects have always been Grovers... got them on my CF...

Aaaaaaaaaaaaaarite ........ too much fun thanks for sharing and 10-4 on the lousy weather....... I’m burned out on it..... cold and windy this morning in reno👎🏻👎🏻👎🏻.... bob

I was lucky enough to have finally gotten a good day to drive the thing home earlier. Very comfortable in that cab all around. It’s also running a lot smoother so now I don’t feel the thumping of the engine in my chest when I’m trying to fall asleep. Other than that I’ve been thinking about digging out my winter coat again...

Just got home...

The only company I know of that really uses metal 3D printers is SpaceX. To give you an idea on cost of something like this and how they can afford it, each launch costs atleast $60 million and they’re one of the few companies that lands and reuses the rocket boosters... there’s actually a launch scheduled for tonight at 11:50PM EST for anyone interested, with a planned landing back at the space center:

Most other aerospace companies use 3D metal printing for prototyping and making castings of components.

This one was listed for sale on here a little over a year ago... worth a look maybe...

Just found these little nuggets for future posts... figured I'd test them out... 

Figured I'd mention it, I heard from a friend of a friend who works at the Hagerstown Mack plant that this corona thing is messing with production because some smaller components that are supposed to come in through the port of Baltimore are stuck out at sea in quarantine. Unfortunately it sounds like the infectivity of this strand is increasing rapidly, which I don't think anyone who actually knew what they were talking about expected.

I think my brother would be interested if they ever made a new highway tractor. He keeps thinking about a Mack Anthem because he likes the look of them without the snail mirrors but won't because of the lack of configurability. Autocar tends to have a different tune with such things and I'm sure they'd win him over with their classic design cues...

No mine is red and i do all the work myself .

Figured I'd ask, the owner of it has a similar name (but I'm no good with names), then saw you had a B model...

What is the rear ratio that is in it now and what is your rpm when your at 55 mph? 

About 2500 rpm in 5th at 55 MPH. No clue on the gear ratio off the top of my head, I'll have to check the manuals on both mine and the sister on Saturday when we go to bring the truck back home... It's either been too cold this week or we've been too busy to drive the thing home from the shop we rebuilt the engine in...

yes im quite familiar ,,,my DM has the same top end......kinda gets old in a hurry with everyone taking you apart on the highway...... gotta new transmission for it a few years ago.....im not sure if it will pick up the top end or not....bob

Luckily most of my limited experience driving the L on the highway is pretty positive, so far most people have seemed ok and in some cases even excited with the inconvenience of the slowed traffic once they realized the hold up was a real old looking firetruck...

Still, whenever we get the money we plan on changing out the rear end to be like the one that was in the sister apparatus which made her top speed closer to 80...

Wow, stick a set of mirrors on the fenders and an old flatbed trailer on the fifth wheel and that'd be the perfect rig to haul my firetrucks to shows with...

well....im sure that truck,will go anywhere now....have a ball with it...bob

It'll certainly go anywhere, including up a wall... just at a max of 55 mph... keeping somewhat local, like within 2 hours of normal travel time and sticking to back roads is preferable...

Looks great! Which show are you talking about?

Hopefully the 11th Annual Mt. Airy Memorabilia & Equipment Sale in Maryland on the 29th. We’ll see how it works out...

Definitely trying to plan to have it at CAFAA’s muster in MD this year, Pump Primers in PA, and the Gerhart All Mack Show in PA. Might try to have them both at Macungie... and maybe a few others depending on what comes up...

This picture was from 2018. It was parked at a different place in 2019.  Not that it really matters. 

Is it normally at the Gerhart show? I’ve only ever gone on the Saturday once most people have left so I miss a lot of the trucks...

It's definitely not a Mack ED. Looks like a Chevy to me but I don't know for sure...

My guess is the last chain drive Macks were E models. But to be fair, I believe I've seen 50s Kenworths that are chain drive so clearly there was a demand for some reason...

That's not a tower, that's a great wall...

No that engine was not military only. It was originally offered by Mack as a part of the newly designed Thermodyne family in November of 1938.

I was referring to the updraft carb on a 707, not the engine itself. I know 707s weren’t military only, my firetruck has one and was just fixed up using parts off an engine from an OTR tractor.
