Thanks for sharing the Fruehauf brocure.I own a 40's era Fruehauf short lowboy that I pull with my BCR.It was built for the Army Corps of Engineers as a pull trailer.Somewhere along the line somebody pulled out the dolly and replaced it with a kingpin.Although mine wasn't in your brochure,it has a lot of the same features as their civilian models shown.Thanks again.

Thanks HK for the info.I measured the housings and the donor camelback rears,but wasn't sure.Without the carriers out of the donor cutoff,I thought something could be off.The transverse tourque rod brackets bolt to the back of the carrier housings,I believe (around where the through shaft would come out of the front one).I got all of that stuff with it,so hopefully it will convert with little problems(yeah right).It'll be done just down the road from you in Oshkosh.Thanks again

Bought a cutoff from a CH with Hendrickson 40LH suspension, but no carriers in it. Have a set of 4.17s from a '74 R, will they fit into the newer housings?

I go every time I make the ATCA show at Macungie. You don't get to see the line moving, but its still a good tour. The show,museum,and the plant tour are a must for the MACK fan.Every Fathers Day weekend it is the place to be.

I stand corrected.Sounds like sometime in'86 was the switch over,huh? I have noticed over the years, MACK did certain changes, depending on where the truck was built (Canada vs. US).Maybe that could be part of the answer.

I think the tan interior came out mid year '73,when the cab got the back wall extended out, and the dash was changed.Then sometime in '77-'78, the interior was changed to more of a brownish(darker tan) color.The best photos would probably be in the brochures of that era.I have some of my '79's interior, I'd just have to scan them. If you would like me to post them, I'd be happy to.As Rob said, '85 was the last of the tan interior.My '90 had the gray,of course, but I was partial to the interior of my '79.I moved a new Granite tractor around at a show a few years back and was surprised it had a tan interior.

Looks like a beauty.Nice find.Something about those old dogs,huh?

Just be glad it wasn't yours,Trent! ..........Al

10-4 ON THAT THERE!

Joe, I have a Ford C-8000 with a 3208 NA that I start up every now and then.In the summertime, I use it as a mosquito fogger! Works great! Like the others say,its something they all do when cold.

Nice grille or grill! FYI, he should put that emblem(Kw) on e-Bay they're bringing a decent buck!

Was at a repair shop the other day and was told that another shop in the Chicagoland area, will be selling/servicing the NEW Diamond T Trucks.I've seen an attempt at this in the late 90's.I've only seen a couple of these in the Truck Paper.I don't know if its a rumor or what. This one used an S-series IH cab. I guess we'll have to wait and see.Good luck in this economic and regulation(EPA) laden climate, Diamond T.Hope you make it.(If its true)!

I had the "PDLO" on my 1990 RD690S. Loved it when you had a swail or ditch or cut out to go through.It didn't care if you had a wheel off the ground as in my '79 with the automatic power div..Was glad not to have to tap the brake pedal to get the auto. to engage,as the old timers taught me!

David, That is cool.Thanks for posting,also.After all it's from TEXAS...and everythings bigger in TEXAS!!!

According to Mr. Montville's book,MACK actually introduced their first marine diesels in 1940!I imagine the events of Dec. 7th,the following year, put the kabosh on that!That crusher "power unit" I talked about is probably just one of the many applications of "homemade" MACK powered equipment examples,all over the world.A MACK fan, Rick from Montana, told me he has converted a few Michigan loaders to MACK power using 673 or 675 and the air-operated wet clutch that UPS used.No limit on the possibities here!

Why not replace it with a 237 Maxidyne? Seems like an easy answer to me.They are plentiful.Parts are available.Best of all,it says MACK on it(and it means it)!!!!

Thad, Was at my local Mack dealer in the 90,s and they had an ad out of a yachting magazine for Merlin Marine Engines.They used an E-6 MACK engine advertised at 700 HP!That was double the horse MACK sold as an E-6 350 horse for the road.I don't know if Merlin is still in business.I think they were out of Florida.

As Superdog said they were to introduce the trucking world to the new ENDT-676 285 horse intercooled diesel.Two companies in our area (Northern Illinois) had them and kept them painted gold for along time.One company,W. Smith Cartage of Crystal Lake (then HQ in Cary) liked the color so much, they changed their fleet color to gold.They got rid of their first 300 Series R after putting about 2 million miles on it.The other company that had one sold out to another asphalt paver in the area.They ran theirs up until about 10 years ago.They drove it over to a pit they own,cut the frame behind the cab.It now powers a roll crusher in their operation.The guys really like it.Like most older Mack products it is reliable as hell and if they get something that stops the rolls,they simply put the 6-speed in reverse.Beats the prybars and other tools and cussing our guys use when that happens!I have a Bulldog Mag from 73 showing the convoy that ran from coast to coast stopping at dealers and truck stops along the way to show 'em off!That tip-turbine sure sounded cool.Had one on a '79 R-612st (300 plus-315 horse).If you remember,that was the forerunner to the chassis mounted intercooler that MACK was the first to use...now everybody uses them,HMMMM........

Don't get me wrong,I liked the F-FL/FS also, just did not like what the "iron moths" did to them.The WS/WL was what I thought to be the answer to the steel cab question.Turned out different.What ever faults they had,I'd still take a G,F,FS/FL,or WS/WL.Only Superdog can say"Got one of those" to all of those!(Not to mention the MH)

Thanks Doug, for the story.Have seen your trucks at Macungie many times.The old MACK vs.KW story (almost of urban legend status)has been going around for years,as you say.Went searching the archieves for this one.I always thought the G was ahead of its time and wondered why they ever quit building it,also?I know the F was the "up and commer"but the G looked like so much more of a truck to me,and a true competitor to west's big three!Oh well, I was only a year old when they introduced the F,and who at Mack was going to listen to me anyway

Mr. HK is correct.A good friend of mine has done just that in a '65 R600 that was his lowboy tractor for almost 30 years!A 237 with a quad using a single disc clutch(loaded with extra HD pressure plate springs) was able to haul his 225 CAT excavator with ease. As the others say, "Be good to the truck, and it will be good to you"

You could A;Tell her it came attatched to some other parts that you bought...B; Bought for her as a Anniversary/Birthday/Sweetest Day/Mothers Day...uh... present?

JMK, Also forgot to mention most (if not all) the turbo motors have oil coolers on them. A necessity when creating higher combustion temperatures. That (the oil cooler assy.) would be another piece of hardware needed for the conversion. It can be done to your present END 673 motor, but why not go with the reliability and parts availability of an ENDT 675 (237hp)? Just a suggestion. I was at a show recently where a naturally aspirated 673 such as yours took off and made some of the best music I have heard in a long time come out of a B model's stack. Again, good luck!
