I would think in 2025 it wouldn't be very difficult to fit some form of K & N filter or something like that on the tip fan and duct it out from under the hood somehow. An air cleaner for the engine wouldn't need to be much bigger than an old oil bath or something as far as real estate in the aircleaner area. They make a lot more stuff now after the diesel pickup craze than back when this was a more popular swap.

Nice Superliner. Can't help but wonder if that'll spark some interest with Spencer ???? They seem to have a knack for locating hiden gems, and I like the idea of them getting into Macks. Not out of the question to see one of those bunks show up for sale some place or on here from time to time.

Ahhhh..... memories of ol uncle bosie. Those zany cannibals alway up to some kinda mischief.

One of the problems with the smaller Mack Triplex or Quadraplex with biger engine was keeping tho oil cool. Once they spent more time in overdrive, oil temp. got to being an issue. If you have a Triplex and a four way behind it ??? you're double overdrive. That bigger engine, likely you'll need a faster axle, and skip the four way. Unless I'm reading wrong

Creeps up on ya, but you realize it all at some point.

Wonder if everyone realizes you need to click on the picture to see them all. Took me a few seconds to remember Other Dog posting pictures like that.

When I was around 20, I used to get stuck doing all that. Got that I could cut motor mounts out and usually not burn anything. Lot's of wet rags.... then you'd get to crawl under and lay in all that (lol) At the time ??? I didn't know any better. I swapped a Fuller 9 speed in one of my CHs one night (no clutch) in 5 hours. It was a reman that had an issue with the synchro. Started when it got in @4 and was test driving @ 9. I ain't got it in me anymore. The CHs were a piece of cake after fight'n old Rs in the past.

Eh....he was happy (lol) My own, I had everything ( I was aware of) in stock. Flywheel, cluthch kit for the Fullers, OTC jack.

Here's a handy little thing I welded up from a grade 8 half inch bolt and an old push in typ adjuster. Bolt it on the cover in place of the push in adjuster and then you can use something 3/4" to get the ring moving sometimes when they're putting up a fight. Sometimes it works, sometimes it's time for a new clutch.

Did an R Model in 6 hours once. Guy was a cheapskate. Just replaced the clutch.

Lots of wet rags too 😂

No rear main. Flywheel in stock already resurfaced.

Think you could still do a dump truck in under 8 hours ? I don't believe I could pull it off anymore. Used to be the norm.

The valve doesn't have to open a lot, just bump it off the seat. It's the overcoming the cylinder pressure is the hard part. Open the lash on a 680 or 346 . Go about .100. be wowed about a week (lol) then watch stuff break like housings or solenoids turned to junk

They could do a lot of things to make stuff work better. Problem is most manufacturers have this thing called a board of directors. They don't really care about anything but how much they can make off of the product. Engineering can only produce what budget allows. Stuff did get better as time went on though. Not many guys can complain about performance of a Powerleash. Then there's the lack of maintainance. I rember the 690 had 6 bolts that held them on to the rocker pedestals. If you read the Jacobs literature, they recomended changing them every 300,000 miles. Not many did, then wonder why they had issues with alignment and oil leaks. Or guys would continue driving the truck with the soft plugs out of the rocker shafts until the shafts were actually gouged out and never be able to keep oil in them like was needed. We're spoiled now with these newer engine brakes that exceed 400 horse of retarding power with relatively little maintainance.

I never understood that. The 680s had lots of oil pressure issues on the top.....and some didn't. I don't remember 690 on the E Techs being like that.

The 690 poked the pin through the adjustment on one valve. 690s had power

The 690 has the pin through the bridge. 680s have the legs that hit the bridge

That's a 690

Eggs are in short supply. Long as they're at the beach.....maybe pound sand intead.

Over the years, I've seen a lot of guys do some pretty impresive stuff on this site. No disrespect to any of them, but man.... you blow them all away. God bless you.

I'd be spraying the angle springs with WD40 . Really isn't much else unless the clutch is shot. Sitting does weird stuff to components .

Yes, you are correct. I am however convinced there are indeed people who make statements like that and truly believe themselves. Somebody's making a lot of money from all this insanity and we're the people paying for it (monetarily). It's hard to watch all this. Every day there's stories about these poor illegals just looking for a better life, while our quality of life becomes poorer and poorer. These people are criminals....period. The ones who allow it are criminals. I've paid more for overweight fines than these criminals will ever pay for the crimes they commit. Sure, I'll get called an a44hole for sayig that, but it's true. An illegal kills someone ??? even if they're caught, they're fed, they're warm, they're not contributing a fu#&'n thing to society. There's people make a ton of money from it.

The mixer is pretty nice, no two ways about that.
