I drove one years ago. Had a 5 speed main and a wide ratio 2 speed rear. The ratio spacing was like a full gear, so you didn't split it. It was more or less just a low hole. I think Brockway called them CT270 or Huskidrive

3.70/5.04 and a direct 5 speed.

My 1951 LJ has the Vin number stamped on the right rear of the frame, above the spring hanger. Great find!

What did Brockway call that? Was it the Huskydrive? Had a powerband like a Maxidyne

JC YES!! Brockway Called it the Huskydrive.. With a 5 speed tranny and 2 speed rear that you only used in 5th gear. Also the had 2 Husky's mounted on the hood.

Forgot all about the double Huskies lol. But I remember that clearly now. I guess drove that truck like 40 years ago

If you get a chance could you photograph that area?  I don’t see anything on mine but there is a lot of paint and some wrecker attachments in that vicinity.

Shots of the front axle.  Some heavy frame reinforcement and welding here

I have never seen that style of Mack Carrier.  I can only assume the front drive has an automatic power divider.  Those rears are before my time .

That long power divider was used until about the mid 60's.  As far as I remember it was a cam and buttons setup like the later ones with the shorter power divider

[Joseph Cummings]

Older style PT pump with the round cover. No built in AFC

[Joseph Cummings]

Damn, are those 55,000 rears?? To put a set of CRD 92-93s in those you had to change the side gears so the axle would fit. Normally those would have CRD 112-113 in them

Looks like air assist power steering....

[Joey Mack]

I too was wondering about the axle fitment due to spline size..

My son and I just got back to Nebraska from Denver with my new to me  and also first Mack truck.   I bought it at Richie bros auction so I don’t have any info from previous owners. There isn’t any id tags that I can find anywhere and it has a new id plate and title issued from the state of Colorado.  I watched the truck sell on “bring a trailer” a year ago for 11000$.  The vin LJ2DX5210D was listed and shown on a homemade metal tag which is probably why a new number was issued.   I did a Quick Look but didn’t see any numbers stamped into the frame to see what the original is.  Any advice on where to look?    The frame has a lot of yellow under the red paint so I’m guessing it was a state or county road dept truck originally.  Has a turbo charged Cummins with no id tag, and a five speed with 4 speed aux transmission, I doubt any of that drivetrain is original, the aux shifter comes up right behind the throttle pedal and kinda locks your foot in there. I drove the truck the 450 miles home on the interstate and got up to 72 mph (2100) and settled on 65 at about 1900 for the drive. Truck had lots of power and drove nice.  I was without alternator , the batteries were hooked up positive ground which I’m pretty sure is backwards as it had a ford car alternator on it that wasn’t charging.  I’m planning on pulling the wrecker stuff and winch off and fixing this truck up for a fun truck and hauling a little corn occasionally with it. 

Where in Nebraska you from?  Terry

Look and see if the tag on the fuel pump is there, Might give some clues as to the engine.

[Geoff Weeks]

Also I'm betting that the front bumper is being used as an air tank, to increase the capacity for the air assist steering, and not anything to do with the radiator. One the hose is too small to flow any amount of coolant, and 2, I only see one hose.

It is plumbed into the coolant, definitely to hot to leave you hand on after it is warmed up.  I’m thinking it is acting as an overflow

Good call!! NTC 335. I thought they were all intercooled

[reb87]

Here is the right side front axle and spring shackles.  Looks like it was welded in, probably messed up any original numbers

[Joseph Cummings]

I never understand why people do stuff like this. It's like they put extra effort into making their rigging weaker. This is how people get killed

[reb87]

Engine shots and Showing the bumper plumbed into the coolant. What is the device on the right front of the engine?
