Wasn't the EN-540 the 185 HP (or thereabouts) version used in the B60 series???

Maybe these will help a little.

And, of course, improperly mounted Daytons can have BAD wobble to them. That wobble CAN have better or worse bounce at certain speeds. They can also go in and out of phase with each other as they get rotated to different positions relative to each other. The '67 I used to drive would smooth out, start bumping a little, get progressively worse, then shake like the world was coming apart...then smooth out again. It would repeat this cycle over and over. Was particularly bad on concrete roads with expansion joints. I took the time to true-up all the rims on the spiders, and it acted like a whole different truck. Very smooth. Well, as smooth as the 55K rears would let it be! Somebody here will undoubtedly be able to steer you in a good direction.

Shouldn't he get some kind of award from all of us?!

Your safety wiring looks good.

Ah, yes! The shims! That takes me back...

That's cool, Matt!

The R611 I drove when I was a young-un had the oil bath air cleaner converted to a dry filter element with a kit that was supposedly available from Mack. I tried to find a kit to do that to the one I had later, but it was apparently no longer available. Considered getting a Donaldson aftermarket body to put on it. Never thought about the gear oil thing. Sounds promising, though.

Well, it looks gorgeous, whatever the case!

I don't do much "socialist media". But, I love it here. Welcome to the Pound.

Absolutely!

I'm still struggling to understand this one. If the front mount is the same, how could the back interfere...given that all the "differences" are in the pulley/water pump. Would be nice to see both engines in person...and with a tape measure. Signed: Curious

I think you should fix it up a little bit and sell it to me. But that's just me talkin'...

That's a long story, Harold!

I'm a huge fan of factory green! But, chrome and polished stainless look cool, too.

Another of my favorites was the Willis Brothers' "Give me Forty Acres".

I remember listening to that song when I was young. And it seemed like, when it was over, you were worn out! Felt like you went on the ride with him. Painted a great picture with his words. They flat wore the "Convoy" song out! It was crazy how often that was on the air. Between "CW McCall" and "Cledus Maggard & the Citizen's Band", they sold more CB radios for the manufacturers than all the advertising they ever paid for. And, of course, there was Red Sovine. I was watching a rerun of an "Archer" episode ("Midnight Ron") where Archer and Ron ran into a group of cross-dressing truckers. He referred to one of them as "CW McCallgirl". Made me laugh..an obvious tip of the hat to The Man.

Yep. You should be good with exactly that. No need to split the gears unless heavily loaded, and even then it's questionable. We've talked about that several times on here before. Empty, you probably don't even need 1st gear. It's kinda fun to show off and hit them all once in a while, though! Still envious of that find! I LOVE those early R's. Grew up in them and the B's.

Beau-ti-ful ride!

Yip. That's the one. Me an' Earl was haulin' chickens On a flatbed out of Wiggins And we'd spent all night on the uphill side Of 37 miles of hell Called Wolf Creek Pass Which is up on the Great Divide We was settin' there suckin' toothpicks An' drinkin' Nehis and onion soup mix And I says, "Earl, let's mail a card to mother And then send them chickens on down to the other side Yeah, let's give 'em a ride" Wolf Creek Pass, way up on the Great Divide Truckin' on down the other side Well, Earl put down his bottle Mashed his foot down on the throttle And then a couple'a boobs With a thousand cubes In a 1948 Peterbilt screamed to life We woke up the chickens We roared up offa that shoulder Sprayin' pine cones, rocks, and boulders And put four hundred head Of them Rhode Island Reds And a couple a' burnt-out roosters on the line Look out below 'Cause here we go Wolf Creek Pass, way up on the Great Divide Truckin' on down the other side Well, we commenced a-truckin' And them hens commenced a-cluckin' And then Earl took out a match And scratched his pants And lit up the unused half of a dollar cigar and took a puff Says "My, ain't this pretty up here" I says, "Earl, this hill can spill us You better slow down or you gonna kill us Just make one mistake And it's the pearly gates For them 85 crates Of USDA-approved cluckers You wanna hit second?" Wolf Creek Pass, way up on the Great Divide Truckin' on down the other side Well, Earl grabbed on the shifter And he stabbed her into fifth gear And then the chromium plated Fully illuminated Genuine accessory shift knob Come right off in his hand I says, "You wanna screw that thing back on, Earl?" He was tryin' to thread it on there When the fire fell off a' his cigar And dropped on down Sorta rolled around And then lit in the cuff of Earl's pants And burned a hole in his sock Yeah, sorta set him right on fire I looked on outta the window And I started countin' phone poles Goin' by at the rate of four to the seventh power Well I put two and two together And added 12 and carried five And come up with 22 thousand Telephone poles an hour I looked at Earl and his eyes was wide His lip was curled, and his leg was fried And his hand was froze to the wheel Like a tongue to a sled in the middle of a blizzard I says, Earl, "I'm not the type to complain But the time has come for me to explain That if you don't apply some brake real soon They're gonna have to pick us up With a stick and a spoon" Well, Earl reared back And cocked his leg Stepped down as hard as he could on the brake And the pedal went clear to the floor And stayed right there on the floor And he says it was sorta like steppin' on a plum Well, from there on down It just wasn't real pretty It was hairpin county And switchback city One of 'em looked like a can full'a worms Another one looked like malaria germs Right in the middle of the whole damn show Was a real nice tunnel Now wouldn't you know Sign says clearance to the 12-foot line But the chickens was stacked to 13-nine Well we shot that tunnel at a hundred-and-ten Like gas through a funnel and eggs through a hen We took that top row of chickens off Slicker than scum off a Louisiana swamp Went down and around and around and down We run outta ground at the edge of town Bashed into the side of a feed store In downtown Pagosa Springs Wolf Creek Pass, way up on the Great Divide Truckin' on down the other side Wolf Creek Pass, way up on the Great Divide Truckin' on down the other side Source: Musixmatch Songwriters: Davis / Fries

You are all over that, '67! And I believe his real name was pronounced like "Frees" instead of "Frys". Great write-up.

Yep. Brown-Lipe Gear Company. Had divisions that made differentials, steering gears, and who knows what else. One of a million totally useless pieces of trivia I've picked up and crammed into my head over the years. You don't want to live in there! It's scary!

My favorite was "Wolf Creek Pass". "...and that chromium-plated, fully-illuminated, genuine accessory shift knob came right off in his hand. I said, 'You wanna screw that thing back on, Earl?'..."

10 speed direct. That's the "Duplex". You can split each gear for a total of 10 forward. 2 reverse. So, yes, a TRD-72 or -722. Probably -722. Could be the "L" or not. Depends on the case material. the 9 speed (-720 or 7220) was direct in 4th, overdrive 5th, so you typically skipped Lo-5th (duplicate of Hi-4th). Just went from Hi-4th to Hi-5th. Mack boxes are "married" boxes, with the compound bolted directly to the main. Not remote mounted like a typical "Brownie" (Named after the Brown-Lipe brand). I always loved the split-shifting instructions they gave (like on the bottom of snowdog's post). They show shifting the main box first in all cases. I never found that to be true. If down-shifting the main and upshifting the compound, I found it better to upshift the compound first, then double-clutch and downshift the main last. Reason is simple. If you have enough RPM available to downshift the main first, then why even bother splitting it! Just downshift the main and put your foot back in it. So, I always upshifted whichever box was going up first, then downshifted the other. Worked better. If you learn really well, you do them simultaneously. But, when you miss one, it's hilarious for everybody else to watch as you try to get them back in, stop, and start all over. Ask me how I know that! In reality, you don't need to split the gears most of the time. You can usually stay in Lo, use 1-5 in the main, then shift to Hi. Probably start off in 2nd even. Anyway, I love that truck. Steel dash. Green interior. 2 sticks (a Mack-must!), and a single axle. Just love it! Kinda jealous!😁

Well, Bob, I wouldn't want to sit on it. But, some might. I try not to judge!
