DM and U share steering boxes?

No.  They share a cab, hood, engine trans and that's about it.  My DM steering box is held on by about 35 bolts, (exaggerating) and my U model has like 6. My U model has a single 1/4" frame rail, my DM is two 3/8" rails.

Yarnall is taking the rear, sorry!

I do believe they're all 673 cu inch engines.  Even the 675/676.

Is an "RM" the same as a "DM" but without the offset cab?

RM is an all wheel drive R model.

Yarnall called first dibs on the rear axle, if he doesn't want it you can have it. 

Top Top line 425

Top line. 11KH-415JCP. Several digits questionable

Lower line reads 117        614753  unsure about the 6.

Rated at 19,040 lbs

Dad says it was a triple A truck, no idea who they were. 

1952??? That thing looks like it'd sell like hot cakes if they rolled it off the assembly line today!

My DM used to have rears so low you could put it in 1st direct (2 stick trans) from a stop with no clutch and it'd click right in no grinding.

Also the brackets off of the tank under the battery box is it is 9” diameter

 

It's 10x24, about 27" end to end. 24" weld to weld. Small tank is 7x14, about 17 end to end.

Large tank is 12x 24, about 30 end to end.

I hear ya. I don't know the owners story either.

Was in a bad mood this morning. Had to replace a cracked dust/inspection plate on my lift axle because the original cracked and was rattling. And of coarse dealer had none in stock when they did annual safety the other day.

So simple job....one nut and one hose clamp. But hendrickson in their infinite wisdom designed it so you have to pull the wheel and the brake drum to get that one nut and bolt off. Awesome. Just what I wanted to do at 6:30 am.

 

Hope it wasn't a spoke hub, that makes it worse at 6:30 am. We pull them off and never put them back on. Horribly annoying to check brake linings, and horribly annoying when stones get caught in there.

I would be I interested I  the cab and doors.  Hood also if available.  Could pickup with gooseneck trailer or rollback if you have a way to load. Please send me pm.  Thanks.  Carey Leitch, Fredericksburg, Va. (50 miles south of wash., DC)

Loading is easy. Take your pick, 1970s Case wheel loader, 1964? Oliver white  2-44FL,  or late 1960s or early 1970s R685ST crane.  Cab is really rough, but if you want it I'll be gentle.  My dad plowed with the truck for years. 

Radiator would fit an r685, at least 2 of my R's, my DM, and this U model all have the same radiator. Late 60's to '80.  Not sure if the radiator in my 1988 R690 is the same, I know my 95 RD is different.  Check your messages.

Do you have a 9 x 20 air tank?

I see 3 air tanks in the pictures, could easily have a 9x20 there.  I'll check, but I expect freight wouldn't be cheap from PA to CA

Apologies, Southeastern PA. Chalfont to be precise. Planning on gutting the truck this week, so I'll PM my cell # to interested parties.  Don't want claimed pieces to sit here long, so I'd prefer local boys to pick things up promptly, helps me keep from tripping over things.

Fuel tanks, someone please take them.  Air tanks, have a spare hood that's in great shape.  All I plan to keep is frame, engine, and power steering. Trans will likely get kept if no one wants.  Aluminum 5 speed behind the 237.

Rolling down the road you see the chrome and miss the hood cracks.

Hi,

I have a Mack Superliner 1988 R721RS1502 with the E9 v8.

I am wanting to find the history of this truck, mainly so I can compare what is still original and what is not.

Is there any resource that could provide this?

Mainly want to know what the original Diff ratios were as well as the original gearbox.

Thanks and look forward to chatting more. 

Pictures or it doesn't exist.  😎

1979 R686ST single frame, 38k rears.

I can get more dimensions if anyone's willing to sell a rail.

My dad's been commenting about a noise while driving his truck the past couple weeks.  Walking around his truck today I noticed the frame cracked vertically at the splay, right under the driver seat.  We would be much obliged if anyone has a decent frame rail in a  parts truck in the Quakertown, PA region. 

We have the harbor freight truck trans jack, works well but you may want to make your own deck adapter to hold the transmission. The "safety" chain is a joke, and the 4 angle iron feet that bolt to the deck are slippery.  Jack handle is very nice, it pivots around so you can operate it from almost anywhere.

The jack is also nice to use for spoke hubs.

You posted it on the internet; I tried it; it works.

Just kidding. 😎

Been slammed at work, haven't had much time to work on it.  Maybe with this coronavirus I'll have some idle time to work on it!

I owned a 2001 etech 400, I couldn't find a single freeze plug on the engine, let alone a block heater. I'm sure it had freeze plugs, but I couldn't find them...

I feel as bad as I did when I was 40. Back then I was going to the chiro 2-3 times a week just so I could move around.  I'm not going to chiro anymore since I bought my inversion table, which does help some.

I won't touch an inversion table any more, I tried my brothers and threw my back out pretty bad.  I let my muscles relax a bit too much and felt my vertebrae separate enough for something to slip between them that doesn't belong between them...

That frame is immaculate.  Could wish for a double frame though, that's a lot of weight pushing down on the frame when the body first starts going up.  Great find, how many miles? Tractor first, so I guess it'll have a few.
