I recently acquired a MACK AC 5 ton truck that is thought to be a 1927. It is fairly complete but I do need a rad cap, cab side name plates & front fenders. If anyone has any idea where to find these I would greatly appreciate any information.

Thank you,
Jack

Ok,that is what my grandfather drove alot back many years ago.
He was driving 1 pulling a trailer for Moss Trucking company hauling mill machinery in 1940 near Gastonia NC when the Crescent Limited high speed passenger train took the trailer loose! :eek: I will have to find the pic and post it. Newspaper said the truck stalled. I guess that is a good thing because the fact is,Grandpal didn't see the train and gunned it to get as much across the tracks as he could.

Craig & all, Here is a start. This is about the only part I could bring home in my 1/2 ton GMC. The rest will arrive when the fellow with the large float has time. (The Do It Now rate is much harder to swallow)

Always Loved the AC Bulldog's. :cool:

Built a couple 1/24th scale models of them 45 years ago and still love them as much now as I did then.

Looking Forward to seeing Many More Pictures of this one.

:salute:

The MACK arrived today! Here are some pictures as it is. The rad looks to be rebuilt & is still in my pickup. The right side running board assembly is new & in the box. The Wood hoist is in the box as well.

It does not have a starter but it looks like there is a boss on the engine for one & the flywheel cover has a bulge that could be opened up to add a starter - has anyone done that? The 5" bore & 6" stroke will not go well with my heart medication.

I need both fenders or patterns and the rad cap or a borrowed one to copy.

More pictures;

I forgot to mention that one MACK front wheel with a good 36 X 6 solid tire would be nice to find as well

With those solid tires, I bet the ride won't do your heart much good either! Rough rider indeed:eek: All kidding aside, looks like you have a nice project on your hands. is the engine stuck or free?

Look's pretty good to me. A good cleaning will do wonders as it looks very solid.

They do ride rough even though the top speed is 18 mph. MACK did have better suspension than others of the period though. They figured it out that thinner spring leaves & more of them worked better.

The engine is stuck from sitting idle for over 40 years. I am told it did turn when parked inside in the 70s.

I am soaking it with ATF/Acetone 50/50 & heating the crankcase from inside with a heat gun off & on. I have had good luck with other stuck engines with that method.

Yes that is the plate that would be mounted on the outside of the cab on both sides. The plate pictured is for an earlier model but would do.

In 1922 the name was changed from "International Motor Co." to "Mack Truck Inc." to avoid confusion with International Harvester trucks.

A fellow collector near here picked up a complete spare motor of one of these from an old sawmiller close out. It wasn't stuck but was mounted on a wood skid for use as a power unit in the mill years back. There was something about those motors, who was actually the builder. I don't recall the details, but I think the motor was built by an outside vendor on those trucks?

Mack built their own engines & most other parts. They have always built their engines but in later years they offered other makers' engines as an option. The term "Built like a MACK truck" is founded on the heavy duty service of every part.

GOOD NEWS; The engine now turns over with compression even!!! A couple of 2 hour heat cycles with a 1500 watt heat gun through one of the crank case ports & a soaking of ATF/Acetone mixture worked in less than 24 hours.

Clean out the oil pan, some fresh non-detergent oil, spark and gas, and off you go! You might want to check the engine bearings before start up, to avoid any surprises later! Hope the rest of the resto goes as fast as the engine!

There was something about the cast in logo on the engine block. It didn't stand for Mack. Maybe it was the foundry logo, I know there was an article about that on the truck forum a few years back and there was another company involved. Was it maybe the International truck co you mentioned above? Just trying to dig up more info. But I thought they claimed that the motor was from another early engine builder. I guess I need to see if there's anything on the website about Mack trucks. And yes I too thought that they had always supplied their own motors back in the day. Possibly the supplier I heard of ended up as a part of the main company.
