1973/74 Brockway N361T in upcoming Alabama auction

Couple of photos of Paul Polizzi's HuskieDrive Display at the Museum, the second photo is an enlargment of the first. Hope this helps.....

Here's a picture of the rear end

Another picture of the rear end

I have the lever in the middle of the picture and the air line. Does that count. I'm laughing to keep from crying. I don't know why the guy wanted to keep the truck when it was butchered like that. Everbody keep your eyes and ears open and in the meantime I will be restoring the cab,hood,and fenders.

[stubnosebrock]

What you have is a single speed rear for sure. Have you checked all the serial numbers to make sure they match? There are 2 tags on the cab, and one stamped in the frame just ahead of the rearmost front spring hanger on the right side. Do some scraping, you will find it. Check all that and make sure they match. Sounds like a truck that was pieced together.

There was one photo with the add that gave the model and serial number. According to that tag this truck was supposed to be a N361T with serial number 79066 in the 1973 production year range according to huskidrive.com Model Year - Serial number Cross Reference chart.

A long, thin aluminum tag they had in the office had the following information on it:

Model NTC-250
Engine# 10462735
Engine Certification Identification: Family-092 CPI-0176
So.No. 15221
Mfg. Date 11-74
Ref. No. 3966-A2-3

This did not seem to match as huskidrive.com Model - Engine Designation Cross Reference chart listed a model N361T as having a Cummins NH-230.

Not really sure which tag actually goes with the truck as they seem to contradict each other.

The best way to find how your truck was built is to contact the Mack Museum. They will send you line sheet and to what dealer or factory branch and first owner. They appreciate a donation. Joe D.

Acording to the # you posted your truck was 1 of a batch of 10 that was shipped to Lakeland truck Center 10 2 72. Lakeland Fla. to Ala. not so far right! It came with an NTC 270 Custom Torque and an Eaton 2 spd 3.70 5.05 ratio. It was a Huskie drive truck

[Junkmandan]

With all the "Hype" about Huskydrive..............,It was just a plain vanilla 2 speed axle! In my Eaton literature................catalogs for parts and service, etc. , I found a catalog sheet fpr Model 20220 2 speed showing available ratios of 3.70/5.04 and of course, 4.11/5.60----------4.33/5.90 and slower . This 3.70 gear set might be a little more rare than 4.11-4.33 for diesels before the Roadranger craze, but would be available to anybody . This catalog sheet is dated 1969 and shows it uses a 20 series housing , capacity rating was 23,000 lbs. on ground[normal service]. I hope I didn't burst anybody's bubble !

It may be true they were a common axle..... but in 2013 it's easy to forget, engines didn't have the flat torque curve we've become used to for the last 20 years. A five speed was pretty much some thing you'd find in a Mack. Point being Cummins powered trucks, aside from the PT 270s with a TO95ALL (vocational) were unheard of with only 5 speeds for use as a road tractor. Brockway always tried to stay with the "latest" trends in trucks, and this was one at the time.

[Emery Johnston]

Didn't burst mine Dan!! I've always sought an explanation of the difference between my 5X2 and a huskie drive and never heard anything that would distinguish the two other than the Huskie drive was limited to two speeds in 5th gear! I assumed it was all sales hype, but apparently many people bought into it!

I got back into this thread...from the later "newbie" thread. Someone said the faster ratio in the rear was 3.07 and others are talking 3.70 ?

I've always been curious if a Huskiedrive could be shifted like a 5&2 and a gentleman posted that he had one and it didn't work...so I have no reason to doubt him. He would know.

I dug the ratios up for the trans.= 6.92 / 3.75 / 2.38 / 1.54 / 1.0 . With these ratios and a 5.05/3.70 rear...if my math is right...and it might not be!......wouldn't this combo be somewhat similar to a Rt-910 / 3.70 rear ?

If you use a 5.05/3.07 with this trans., it is not 10 progressive like the man that had one said.

Safe to assume it is 3.07 ? if so.......if you could get that 270 wound up....she would fly !!

What's anyone else think ?

John

[sbrant358]

That would've been me who said it was 3.07, which is a complete mistake, I meant 3.70 and went back and corrected it. If I did this right by multipying the rear end ratios by the transmission ratios, it looks like you could go straight through the transmission and split every gear, but some of the splits seem really close and some are pretty far apart.

[359Huskidrive]

The Huskidrives that I drove back in 1975 topped out at 62mph at 2100rpms. If that helps. Carl

[stubnosebrock]

My old truck will run about 72mph with 20 in rubber

[John Woge]

Shelby....

That's kinda what I thought about the ratios. I'll see if I can post the rt-910 vs. huskidrive for comparing after church.

this is interesting to me....wonder if someone knows how to get it in the proper form....not the four sale section ?

Just to compare, John

[myfirstbrockway]

I love all the discussion about the huskidrive. I just wish somebody could tell me where a 5.05-3.70 rear is where I could buy it and make my huskidrive truck back to where it should be. thanks guys

[MARK T]

Huskidrives were from a period of time when trucks started to get more power. Not as we know it today, but back then a truck needed some lower axle ratios to have power. The only way to get any road speed out of one was to overdrive it or double overdrive it.... and until the early '70s most didn't spend much time in "overgear" A truck that might "pull it" in overdrive tended to make for a short transmission life as high overgears generate a lot of heat. So with a Huskidrive, you had a low ratio axle for power and a high axle for cruise speed, but not the headaches of a big overgear. and yes an RT910 is a direct transmission same as the five speed used with a Huskidrive one turn in.... one turn out
