  1. Hi, I'm wondering if you think you have gotten a plausible answer to your original question? Regards Jeff.
  2. Yes Vlad, an NR is really a Military L, I'd say an LFSW.
  3. Hi, The difference between a DM and a U? I would say, simply, that a DM is a DM, and a U is an R with an offset cab.
  4. Hi Pawel, You are doing a great job. I am a model builder too, and I also like to see accuracy under the cab n hood. I like to see correct chassis under the model. I have an Italeri Superliner but have'nt built it yet. I will be making proper Mack X-members and front chassis section based on Australian trucks. Did you know that Australian built Superliner and Cruiseliner were built on the R model chassis. Mack also used the R model chassis for the CH and the Titan. The 1st CH's were CHR's Also around 1971 Mack Trucks Australia (MTA) started using the R model chassis for the F model, they were designated FR700. Regarding the rear end in your model, I think it is a 1/25th scale 58-65,000lb representative. With the detail work you've done on the front carrier I think it is a pretty good 1/24th scale 44,000lb rear. Jeff
  5. As Fifth Wheel said. They were factory built. The 'E' designation stands for 'Extreme' as in extreme service, some people refer to them as a 'Tropical' radiator.
  6. I think that shift instruction plate is for a Triplex. I have seen F600's and F700's with 14 sp Quadruplex transmissions. They were in F611's, F715's and F719's.
  7. The R600 at the top of this thread looks to me like B4 1972 say. I have to be careful because in Australia we were about 6 to 12 months behind the USA in what was available, and we did'nt have all options. But the old style spoke, small letters MACK and the small grab handle all point to about pre 72 in my opinion. Bearing in mind that anything can be changed or modified, i.e. the bumper in my opinion is post 75/76 clearly not the bumper for an R that looks like this one. In saying that, those smaller grab handles are'nt easy to fit to a cab that was built with the longer grab handle. The chassis # might be the real indicator, the number looks like an early 70's number. However the truck does'nt look like an RS600 to me. Then again it could've had a rail change. so going on appearances I say a pre 72 R600. In regards to the 1/2 Dogs on the doors, In Australia we did'nt see them till about 1968. These trucks that hit the road in 1968 could've been built 12 months earlier. These are my observations.
  8. I will say none to Australia. The U model was, I think a Hwy truck and not at all able to be converted to RHD. However there were quite a few DM800's, again not engineered for RHD. These DM's were used for exploration work in remote country, or for work in civil construction and mining. Later Mack produced the R800, which was essentially a DM800 with a centrally mounted cab, like an R600. This chassis could be built in RHD and many were built here for exploration, off highway dump trucks, mining semi trailer and road train, and on highway heavy haulage. I did once see what I thought was a DM600, in the late 80's. It was a concrete agitator, it was white, and had a 'Mack Western' style grill. A U model is really an R model with an offset cab. The only similarity with a DM is the offset cab. I think a DM600 is a continuation of the B57 and B576 construction range of trucks of the mid 60's. An R800 is essentially a DM800 with a centrally mounted cab. R model and U model, use the same chassis. B57 and DM600 use the same chassis rails DM800 and R800 use the same chassis. Can anybody say what chassis rails a C600 uses? Does it have it's own chassis rails or does it use F, H, B or R chassis rails? Does an H model and a B model share the same chassis rails I think the C600 chassis has some similarities with the R model chassis and maybe suspension like a DM600. IDSTBC.
  9. Hi Mort, Firstly, this info only refers to trucks available in Australia. Are you refering to the cab or the hood? For the cab, they first appeared in mid 1973. I beleive there may have only been about 25 or so trucks built with this cab. There was no changeover date, the RP (Reinforced Plastics) cab was an option. The RP cab seemed to disappear around or just after the time the new steel cab was available in Australia, about mid 1975, When it comes to the hood/bonnet, both were available basically from the first release in 66/67. By about 1971/72 the steel butterfly hood was only seen on severe service trucks, and the fibreglass hood appeared to be the standard hood arrangement. Hope this helps Jeff.
  10. I'll have a stab n say it's an R model of some type. In Australia 'AXXXXXXX' is the VIN part, A= R model then the #
  11. Hi, I'm looking for a 1960's 'F' series parts book, 6 or V8. What have you? Jeff.
  12. Great decals, I'd buy many, I know blokes whod buy some too. But they are not available to Australia.
  13. A good piece of Mack 'F' action, truck looks new. Sounds like they've used the soundtrack from 'DUEL'. Thanks for the link.
  14. I always thought it was early fender,(the top one) and later model fender,(the bottom one). Maybe one fender has been replaced at some time giving the truck odd fenders.
  15. How does that sayin go?, "If you have'nt got anything good to say, say nothing"
  16. Hi Skip, you've done a great job. Good to see it looking original. Nice pics. Regards Jeff.
  17. Yeh great pics, thanks for sharing them. I love seeing pics of Allentown, particularly when it is the truck lot. Jeff.
  18. I think it is a REO cab, used by REO, Diamond T, Diamond REO, White and others.
  19. TBone, If the engine is unaltered from original, I'm talking about appearance, then that Perry water filter dates it to about mid 60's at the earliest. theakerstwo, I have never heard of an ENDT674, or an END674, please enlighten me. I've found that the blocks without provision for piston cooling are not 'T' blocks. AFAIK there were only two Mack engines built turbocharged w/out piston cooling, they were the END673T and the END864T. All engines designated ENDT have piston cooling galleries in the block. It is the 'T' in the ENDT that indicates this. The 205hp Thermodyne, Mack's 1st turbocharged engine, is officially an END673T, just an END673 Turbocharged. Whereas an ENDT673 has a block designed for/to be, a turbocharged engine, i.e. amongst other features, piston coolers. BIDSTBC Jeff.
  20. TBone, it could be a 237hp Maxidyne, an ENDT675, the original Maxidyne, you need to look at the engine #. The numbers on the fuel pump and turbo could tell also, providing you have a manual that tells you how to interprete the numbers. By numbers, I mean numbers stamped in to a plate riveted to the pump or turbo or stamped in to the body of the pump or turbo. Any numbers cast into the block or other components are common numbers to thousands of units produced. These numbers are ok when your looking for a replacement item. I'm pretty sure an ENDT673 Thermodyne block is the same block as an ENDT675 Maxidyne, but an END673 or an END673T Thermodyne is a different block but it looks the same as a ENDT. I do stand to be corrected. Jeff. P.S. The engine # is stamped, not cast. It comprises engine model/type followed by the serial# of your engine. Engine numbers are typically, depending on age of engine, END673P 477-60, END711-51-H96, END864-8-29, ENDT673C-2X-1234 and so on. Later engines were just T673C-2G-2345 or T675-3B-3401
  21. TBone, my guess by looking at that engine, if the engine is an unaltered engine. The large oil filter, a WBG, the oil cooler that I think I can just see in one pic, I would say it is an ENDT673 or 675, as opposed to an END673T. Not sure about an END711 Turboed. Jeff.
  22. An ENDT 676 is the same engine as an EM6 285, Mack simplified the I.D. around 1980 I think. There is possibly minor differences between the two engines, but essentially the same engines. Gaskets could look different but should interchange.
