If you look under from the rear of the truck, just below the check plug in the lower housing, there should be a number stamped in probably starting with S, like SS44C, or something similar. That is the model number of the axle. For the ratio, look at the front of the forward rear, and just to the left of the power divider on an angled flat spot on the top housing, there should be a carrier model, like CRD 93 or something similar, and a ratio like 4.42 or something similar.

Barry,

I have tried to use that on other sites, but was not able to. I hate to open another account on another site just to be able to do that. Is there any way that you can make it more user - friendly (for dummies like me) to use a third party host, or post a detailed tutorial? Maybe that will encourage us all to do it that way.

I for one, appreciate Barry's hard work and dedication to the site. THANK YOU, Barry! I come here for the informative truck content and pictures and technical information, and if that was all that was on here I would not have a problem with supporting it. However, there is occasional content that does NOT add to the quality and the purpose of this site, and that's what I have a problem with. Oh yes, I can ignore it, and I do, and I have never complained about it. But I cannot support it either.

I also appreciate the quality postings on here by most of the members, especially here lately there have been pictures and information shared that can not be found anywhere else. For those members, THANK YOU.

This too will probably blow over, and life will go on. Just my two cents, now I'll shut up.

This topic came up before. Somebody posted this list from Don Schumaker at the Mack Museum.

I don't remember where I took those, maybe Macungie. Don't know where it went.

How cool does a set of stacks coming up through the middle of the hood look? Oh yah! What is the engine in that LRVSW?

Cummins NVHB, V-12 1486 cu in natural @ 400 hp. I believe trans is 9 spd w/ torque converter

Dave thoses 2 dumps that my b81 was sitting in between those were both M model macks right, may be a little smaller then the ones in your pics above. Thanks for sharing those.

No. One was an autocar AP-15, the other is a Mack LR (15 ton). By the way, the MB fire truck is back here if you want to see it.

The bodies for the Mack M's were built by others, mostly Heil. The smaller ones were assembled at the factory. The largest ones were likely shipped to the end user and assembled on site.

From Pit & Quarry magazine November 1971

ET477, never knew there was such a thing. I knew the 400 series chassis used an END475 (6 cyl n.a.) @ 140 hp. Never saw a ET477 6 cyl.

A guy I worked for had a 475 in an R400 ten wheeler dump. At the time I was running an International R190 tandem, The 450 cubic inch gasser would run circles around the 475 Scania.

Might be good trucks, not much dealer support, imagine taking one of those to your local truck shop for parts and repairs. And if you think a Volvo has a sharp depreciation curve, try trading a Scania back to any new truck dealer. Here we go again, trying to compare apples to pears, a product from the past to current product.

That looks like some kind of component (injector pump?) arrangement number.

Nice. Reminds me of the Slattery (from NYC?) LJSWX's

I don't know about oil cooled pistons, I don't have a spec sheet on it, but I do know an ENDT673C @ 250 hp was an available option in R, RD, F and likely others. The 673T engines used several different intake manifold arrangements, including the "tin" manifold that the 675's used, and a two piece cast aluminum manifold.

If you're looking for an answer on the gator, in past years it has been OK. They asked that they be registered at the show. (don't know if they want proof of insurance - may be covered by your auto policy) Maybe Doug Maney will see this and let you know for sure.

A good friend of mine bought an older RD tri axle dump years back. It was a "300" (676) and it ran really good, but he was concerned about the fact it would easily turn 2300 rpms under a load and really smoked. He took it to the local Mack dealer and ran it on the dyno, turned out it was putting 400 horses to the wheels!

Needless to say, it was their recommendation to turn it back just a little.
