If a face came off a lifter, you'll have a hard time seeing that from the top. Pan needs to come off. Those on occasion come off in only a couple pieces sometimes too big to fit out the drain plug.

You'd like it. Lots of nice trucks and lots of good people. If you happen to be able there when the weather is good it makes a great show even better.

That picture looks like the hood and the radiator shell are both extended.

I might be way off on this, but I think the Brockway name is now owned by The Brockway Truck Preservation Society ( the guys with the show in Cortland every year ) as far as the glass goes, that's in Brockway Pa. ( name of the town )

No playing around ( lol ) Wait until you get it back together after everything you have planned. I think you'll be surprised at what one of those sounds like in the hood area. You'll likely not hear much at idle other than belts...and it'll run as smooth as the paint on that truck. Best part, you can go do whatever you feel like without any worries .

How is it I've never seen that red and white one ?. I see the other one quite a bit.

Awww...an animal lover (lol)

In reality, a CMCAC just exits from under the hood.

Paul makes an interesting point. Tip fan needs some kinda filter. In this day and age maybe there's some kind of filter from K & N or one of those that's friendly to modifying for something like that. A cool power in a B ? What about air in air out somehow on the fillers between the hood and fenders 🤔

Wasn't there a couple MLRs ? One had ratios very close to an 8LL and one had a few reverse choices .

The one with the "cone" is a full floating axle. Those you don't hit when you take the six nuts off of it. The center of that cone is only a soft plug. The "cone' or drive plate is splined to accept the splines on the axle (just like in carrier on the side gears) the other type with the flange ( flange and axle shaft one piece ) is the ones you smack in the center to get out. Usually the wedges behind the nuts don't like to give up easily on older stuff and they can be frustrating to get out. I agree with the others , the front ones are likely from different size axles (weight and bearings) So likely not much of any of it will interchange between the two trucks.

When Macks had grey engines in them, they had a pretty good idea of what would work together for the trucks application. Some stuff will go together in other configurations and some won't. Grey engines either had a wide torque band or a little higher horsepower ( one or the other ) the "torquey" ones often found their way into vocational trucks (mixers dumps) and had some form of extended range transmission. The higher HP ones usually went into road tractors that needed HP to maintain road speed and usually had transmissions with multiple gears for on road ( anywhere from 9 up ) Sorta a generalization ,but might help your decision

I'm not sure. But if that picture is from the inspection hole on the top , it might be

72 series .. I thought I saw it in the picture he posted . looks like the part the release yoke comes in contact with.

Some had some type that worked on the counter shaft on some models. NOT the one that is squeezed by the release bearing

I doubt the engine you describe would work great with a 5 speed. Needs transmission with some gears and depending on weight maybe even a thought about axle ratio

Weren't the Maxidyes (237s) with the two side by side and smaller compared to the engines with a tip fan that were one on top of the other and bigger diameter ? I think some with a Strata Tube had the air cleaner that was smaller on the top if it had the under hood draw for bad weather too.

Not sure , but if it's a 350 it's not going to be the highest torque.

Boy, they went all out . Looks like Guerrilla Tape ( the good stuff )

I said " looking" 🤫

Maybe he needs it to be some kind of compliant looking for where it goes. This is a interesting swap even if considered blasphemous by some. I never knew a Cat can communicate with a VECM on the Mack (maybe it can't) and yes....hot air. the air needs a little help get'n that lean fuel mixture to light on those environmentally friendly Cats 🤣

A '99 ? I doubt it was a ACERT. That's more like 2WS era

Certainly looks like one

I think that's an ACERT ME Wow
