Does this superdog run novadays? Really cool picture. Someone must be happy catching the truck on a road with so good point of view. Thanks for sharing, I now too doubt I would be able to step on the Brown land myself in the distant future.

And the engine in the original talk was a boat application. My guess is if you have water all around you some also may circulate over exhaust manifold. I'm not familiar with marine engine engineering though.

If so the matter is clear to me. Never put a wrench on a 237. Thanks Glenn.

One thing I haven't figured out is how that assembly holds in place? I don't see any clamp or a brace. Were those "compression" rings supposed to lock the tubes by just tension?

That's probably because the seller read this thread and figured your father is a seriouse potential buyer

In Iran probably...

I remember seeing a youtube movie of how a man was making piston rings. Those were of a simple square shape, almost as on your tubes. The way was really simple. The guy had a piece of cast iron pipe or so (since the most piston rings are made of cast iron), put the pipe in a lathe and cut a ring of the size he needed exactly (as compressed to the place). Than made a cut, put something (steel rod?) between the ends expanding the ring after which heated it up with a small torch. Getting red hot the ring failed off the rod loosing its springness but got it back right after a minute. I was going to try doing the same but the plan as usually went on a back burner. Sure may be just a movie but seemed real and also not difficult to make a try repeating.

Renault didn't have such the thingy either. Same as in a US truck, integrated into the timing cover.

Wonder what actually B66 was? B67 gasser?

Hope you're able to leave your lovely shop earlier today and cut off a bit of time to add especiality to the day. Best birthday wishes! Many more to come!

Books tell original NO was 102 inches wide. She can't be much wider at the moment.

Looked quite complete when I saw it in one known place in CT in 2018. The cab is sure not factory since there was an open style military cab. Also front bumper was modifyed and wooden cargo body gone. But would be a cool truck if put the original style cab (which you would definitely have to fabricate) or one off an L-model maybe and just keep it a tractor. One of carzy ideas which popped up in my excited brain when I saw it was to make a replica of experimental Mack NQ. Looked damn impressive with a 5th wheel and a C-cab which seemed even easier to make than the military one (ask me how I know).

Now it looks like it was possible to install (or remove) those shims with tranny in place. Loosening all the bolts and than taking off one at a time and putting back with a shim. Would be interesting to learn how Fort Wayne guys calculate what you need of shims to add with a particular flywheel, disc and pressure plate.

Very interesting, thanks for clarification guys. We know some applications where friction materials work in oil such as motorbike clutches or clutches in hydromechanical automatic transmissions. This way it seems quite possible to do the same for a small part in a big truck

Welcome to BMT! Nice looking old R-model. And looks like the truck has plenty of potential. Wish you good luck on bringing it into working order. Also would be cool if you not limit your activities with just making it road worthy but also find resources to improve the look. This way you may please lovers of old Macks and also jobs you're going to do will be done with pride. Dash panels you're looking for is relatively easy assembling stuff. If I were you I'd start looking for a set of parts over junk yards. Preferraby still installed on a truck. Of what I saw on the pics you posted in another thread you would need a steel channel which goes from the left door sill to the right one. There's a piece of angle steel or so installed there at the moment since some previouse owner needed something to put parking brake knobs into. But factory dash wouldn't fit on it. Also there used to be a heater box which installs right below the dash. R-model was made the way the heater is a separate part so you can assemble all the dash without and put it later on. Vlad

Should friction surface of a clutch brake be greased??

All injection lines are metric. I found myself about almost shocked when discovered that both delivery valve housings and injectors had metric threads on Lanova engine made by Mack in 1945! The pump was made by American Bosch though as it was written on its tag. END673, 237 etc all had metric connections at the pumps and injectors. I'm not almost sure on the thread size where the lines go into the head housing on E6, E7 and E9. But my bet is they're also of German origin.

My guess is if you use Swishy's trailer as a chassis and build something similar in Barbie style it may work out as quite comfortable accomodations. On the other hand that tiny home on the pictures is a finished object ready for living and travel so a person who wants something like that may be lucky just bying it and go make his dreams real.

Bob, it looks like a trick with a long focus camera in the first pic. There you can see a low window at the right than a door and than another window. And the stairs at the left probably allow to get to a sleeping compartment which is above the photographer. When we look at the 3rd pic that same sequence of the low window than a door and a large window appears. Also you can see a narrow window above the low one so suggestion on the sleeping compartment above that point the 1st pic was taken from gets making sence. But now it clearly seen that hypotectical sleeping area is only 3 planks high. Ok, maybe 4 including some space in the "loft" but we should reserve a bit for a matress.

The heater box and the lever boots are eye candies! And both the dashes too! A point - sticker or a plate is needed to attach onto the cab lifting pump with notice to "unzip the sticks before lifting"

The difference between Maxidyne and Econodyne is the torque curve shape. The difference is achieved by the injection pump settings and the turbo. I too would like to learn what particualary is changed in the pump but haven't seen leads to such info so far. Speaking the matter of your interest both E6 and EM6 have similar metal. Heads, pistons, rods, cranckshaft, bearings etc. I'm not almost sure on the cam shaft, maybe someone else can explain that point. Head gaskets are also similar between two engines. Worth to admitt there were 2 valve and 4 valve E6-350 engines and 2V and 4V EM6 either. The gaskets used on 2V and 4V are also of the same style (same part#). It seems surprizingly since 2V and 4V heads sure have different design but Mack fitted them using the same gaskets. PAI number for E6 head gasket kit is EKG-8425 which conteins EKG-8424 gasket plus 3 EFR-8421 steel fire rings. One kit is for one head. The number you mentioned is probably a big upper engine kit or so. Also worth to point out Mack engine overhaul manual prescribes swapping the head gasket as a recommended procedure. But the fire rings are the must. Actally the gasket seals coolant and oil passages only with the combustion area sealed by the rings. New PAI gaskets aren't expensive though.

Don't know how these things are at your side of the globe folks but in my neck of the woods there are shops which can apply Titanium nitride on steel or SS or many other metal parts. That way the parts get real gold look. You can get polished look if the parts were prepped correct (pre-polished) or smooth look if the surface was media blasted or so. The most common particular applications are teeth coating to make medical steel (which actually is SS) to look like gold or different cutting tools such as drill bits, bores, lathe cutters etc since TiN also has very high wear resistance. What is important point in what I typed (since I suppose plenty of members are familiar with that coating) is many shops overhere offer such coating for small lots of parts and quite affordable.

Yes, Back Mountain area. The pic was taken in 2018. After seeing that truck in person RD800 took place in my favorite Mack list.
