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.

Happy B-day!

Best B-day wishes Tom! Hope the day is nice and all Winfall wimmins Zina from Florida keeps you in focus of her attention. Sure I belive production of hot sauce is well supervised.

Well, now I understand I saw similar cabs on Western Stars of late 80's. Thanks for the detailed explanations, interesting.

There's make an offer option in the ad. Also the seller may be count out with some efforts for a straight deal to avoid e-bay commission. And I belive there's a bunch of BMT guys out there in NH so there's a chance someone would help picking that headliner up and bring to a truck show or send by ocassion. Just thoughts. $750 doesn't sound as for free but on the other hand purchase would solve a problem if such one exists.

Yup, those bird catching devices were installed on some American trucks too.

Great to hear Ray is in contact and continues providing transportation services. He used to show up on here regulary but seems plenty of time passed by since. White looks really nice, congrats on the purchase! Is the cab similar to what was used on some Brockways and Autocars?

Impressive thingy! Does that engine have decompression setup or anything else those "second injection lines" were used for?

We are no less anxious on that than you

The housings for airride and Camelback may differ by the attachments. Pre-90 Neway usually had double "cleves" at the bottom side which were a kind of cast steel bracket with two ears for bushing welded onto the axle housing. Camelback axles have pads at the bottom to accomodate the rubber pads and clamping caps. The pads are cast together with the housing if its cast style or a weld on part for fabricated housings. Once I met interesting setup of Neway equalizer beams connected to "ears" which were steel brackets attached to cast iron housings by bolts. Actually the housings were the same style Mack use for Camelback. But these "ear" adapters allowed to use them with Neway suspension. And all looked like factory setup, not home made. Also different truck models had different width of the rear end of the frames. The most of earlier rigs such as R, F, DM and also B-models I belive had 33-1/2 measured at the outside of the rails (with small wariations due to the rail material thickness or presence of outer rails etc). But newer trucks like RW, MH and than further CH/CX had different distance between the rails. That means different distance between rear suspension parts and as a follow different positions of attachment elemens on axle housings. So all in all you should pay attention to style and location of mountings on particular housings you might be wanting to swap in. Speaking the initial subject of the thread I'm with you on preference to be sure every important part in a truck or other vehicle has its properties according to industry standards and quality. We're supposed to belive factory things such as a truck or a car made in a plant were designed and build the way they should be to drive safe and reliable. And when we meet a fix which doesn't seem done correct big preference is to get rid of it by redo or swap. If a weak link takes place in a chain the fact it haven't broken yet doesn't mean it will never do.

Me too

No Keith, looks like they're not. At least 3 R688 of the SGT bunch had the spring brackets with tow pins incorporated (and used no spicers) and also there was one more R which I purchased a hood off and it had the same style brackets and VIN starting with 2M2N pointing to Canadian assembly. All those were made in 1988. On the other hand the truck I mentioned in the post above was Matt Pfahl's (from Connecticut) restored R-model I crawled under for a few detailed pics accordingly to the condenser mounting (to fit it properly to my R). And that truck had spicers (as I mentioned before) and American VIN-code 1M... Built in 1985. So my guess the spicers were an option. I don't see any practical use in setting the tow pins off to the front (and putting them in one more separate part hold by bolts instead of a generic chassis part as the spring hanger) so probably it was a matter of style. Same as two bumper options for 2nd generation Superliner. Modelbuilders must be happy with what we describe and show out with pics definitely
