That brings up something I was wondering about:
How did that work in Australia with the DM/U model cabs being offset to the "wrong side" to be compatible with driving on the left side of the road?
HK, thats a point, because the DM's were'nt easy to convert to RHD the R 800 was a more popular choice particularly for hwy use. I dont think any DM 600's landed here. There were no U's, as they were a hwy truck I'm sure and offset cab Macks could'nt be converted to RHD without being silly. We had R 600 RSX's for heavy duty 600's. DM 800's were used for off hwy use and oil field work but the R 800 was the choice, thats what I reckon. Regards Jeffro.

I think the only DM's we had in Oz were 800's, from what I can workout the 800's have a chassis with a sraight thru profile like a B 80 series,and only have steel fronts. The 600's have a profile like a B model except deeper at the front and have fibreglass or steel fronts. The U's have an R model chassis and I have only seen them in fibreglass fronts. I think the U's are basically an offset cab R model. Regards jeffro

Does this VIN mean it was the second DM800 or the second with a Cummins? Do all VIN production numbers start with 1001?
I think it means the 2nd with a Cummins something,from what I can gather if it is a B 615'T' 1001 the next one could be a B 615 'ST' 1002 then 3rd could be B 615 'SX' 1003 there could be ten all the same thru to 1013 then there could be a B 615 'X' 1014 but it would change if it was a B 61'3' T eg 1001 B 61'3' ST 1002 B613'SX'1003, so long as its a B 615 or a B 613 or a DM 865 I dont think it matters what it is behind the cab. Thats what I reckon. Regards Jeffro .

I would use them. Are the later Thermodyne badges available? Like on F models, capital letters with a line under, I'd be interested in a couple of those also.

Hi Gary, END 673 170 hp, END 673 P 180 hp, known as a 'P' motor . Regards Jeffro .I have been told that the exhaust manifold from a 673 diesel, 170hp, will work on my 1962 Mack B-85F fire truck with a 707C gasoline engine. The source of this information said that he had a cracked exhaust manifold on his 1961 Mack B-70 tractor with a 707C and the 673 diesel, 170hp, exhaust manifold worked fine since the engine blocks are almost identical. He said the 673 diesel exhaust manifold is easier to find.Any thoughts or experience you folks have in this regard would be greatly appreciated. Is the 673 the END673 and if so, does anyone know the letter for the 170hp, i.e., A, B, etc.
Thanks again,
Gary M. Belt

Hi Martin, the stands that come down from the frame are referred to as a pedestal, the tube is called a spindle,some are hollow some solid, the trunnion slides on to the spindle. The spindle is clamped to the pedestal with the 4 bolts each side, there should be a collar between the pedestal and the spindle. Regards JeffroBear with me on the lack of correct terms here...I've got a 1965 B set up as a dump truck with bogie camelbacks. The caps that hold the trunion tube to the trunion stands( or do you call it supports?) have 4 bolts on each side of the truck...and they are marginally loose. One even has the head popped off. There's even some space between these bottom caps and the tops. Just to clarify here, I'm not tallking about the ubolts at the spring pads/perches.
A couple of questions for you expert wrench spinners....
Should I tighten or replace these bolts and nuts? They're pretty rusty and funky. What grade should I replace with?
Could someone explain to me the function of these things that I am calling caps? Seems like they hold the trunion tube up against the stands. SInce the wieght of the truck bears down on the trunion stands and onto the tube, it seems like these only serve as to hold the trunion in place (and deal with the bouncing up of the suspension system when you went over a bump, for example. Is this correct?
Thanks for bearing with my lack of correct terms and for helping me understand what purpose these serve and how to fix.

James, the #'s you have in your photos are the block cast #'s. The engine # stamped on the block should be at the very front of the block below that compressor, on the top edge of the timing gears caseing. Early COE engines had the # stamped across the back of the block just below the head although I think that by the time the Coolpowers came out all #'s were at the front. Other than that you will have to get the #'s from the emissions plate, on the block behind the fuel pump or the #'s on the fuel pump could translate to the correct engine. Hope this helps , Regards jeffro.I have a 1963 B75 that was purchased from OLDMACK.COM and can't identify the engine that is in it. The only thing that I know about the engine is it's supposed to be a rebuilt Mack 300. The data plate on the side of the block is covered in heavy paint and we are trying to get it off but not sure if we will be able to read it.Can anyone ID this motor by these pictures on my photobucket?

Ok so I get it. In the flat ground my right stick will stay in direct. Which is downward. Then I shift my gears normally. When I'm pulling a grade which I will be with switchbacks and mud and all I'll put the old dog in lo and shift them. There's no splitting involved...
If its a 6spd you'll only use Lo in first gear, then shift to Hi go thru 1 to 5. When you select rev, you have 5 reverse ratios.

Hi, looks like an early 30's type 19 pumper, based on a Mack BK chassis, would be a 6 cyl eng. What a gem you have. Regards Jeffro.

HI, I think the mounting is referred to as a pedestal, it is a cast steel pedestal. Its been around virtually unchanged since at least the L models, 1940 and maybe developed just before then. I think that was the only one until the inside frame mounted pedestal was produced, maybe around the time the B model was released and it appears this was the lightweight pedestal, it was also a cast steel unit used up till about mid 60's. Then came the fabricated pedestal which is also inside frame mounted and I think there was a heavyduty version also. I think the heavy cast pedestal was used up until about early 90's when airbag became the norm. Mack was using a camelback style spring on tandems in the mid 30's with a different pedestal arrangement. These are just my opinions based on my obsevations studying Macks. Hope this helps you, regards Jeffro.What years was the outer frame mounted camelback suspension used? Was the outer mounting used with the lighter rear axles? -
When the Maxidyne was released in 1967, it was rated at 237bhp, 906lb.ft. torque. To get that torque from a Cummins you had to go to about a 270 Cummins of 855 cu.in. The maxidyne was only 672 cu.in.

Hi,what model truck do you have? Is your original air cleaner engine mounted or on the outside cowl mount or whateva? Why would it have to mount horizontally? What are you doing with the truck, i.e. a working truck earning its keep or just an old truck to drive and take to shows? Regards Jeffrohello guys looking for a simple chrome air clearner for my 47 mack 707 eng. to replace that big monster oil bath air clearner ,it would have to mount horizontal, thanks -
I think the canister on the macks was WGB brand, they were on the early Maxidyne & C motor aswell. They stopped using them around 72 although it may have only been on 6 cyl engines at first. Mack called it ESI, extended service interval. jeffro

Hey Super, I got a pair 6 mths ago, I hate them. But that DM, I had to look twice, cause I had Maxi V8 in my head because of the 865... JeffYou're right,Jeff,I read that VIN wrong.Guess my wife is right,I do need to think about getting glasses. -
Hi everyone, the shift plate for the 14 spd says to "use 5th in Hi-Split only" that equals 17. Maybe only use 1st in "Lo-Lo", that equals 14... but the plate does'nt say that. .Regards Jeffro.

DM 865 SX ? I think 65 would be a cummins, a 237 would a DM 885, a GM would be DM 87x I think. Most Cummins engs are in the 6's. It could be a typo. Pretty early DM . There was only about 25 DM 865's built between 67 n 73... Regards Jeffro

Hi Russ, I looked up some model #'s and found that a DM 845 is an NTC 335. Interestingly there is a DM 863 also with an NTC 335. I dont have spec sheets on either truck but the listing I have shows the tare weights different for each truck, the 863 weighing in heavier than the 845 by about 855lbs. Regards Jeff.Hi Russ, 45 is a Cummins 'NT', I found that somewhere in reference to an F745. Regards Jeff -
Looks like a Renault badge on the door. JeffIt could be a Magirus -
Hi John, I think judging by what happened to the truck at the end of the movie that it was a wreck, and probably sold off as parts and srap. I guess thats what happened to the Peterbilt in 'DUEL' aswell. regards Jeff.I have posted some photos from the movie in one of my albums showing the truck in action. I'll post a few more from the end of the movie where the truck is laying on its side with the tri-axle tanker behind it.Regards,
John

The no engine number would be right. The the engine in my mack now, came from Gleemans and it never had an engine number stamped.
It had a Mack pedigree Re build plate 6/97. It came from the US. It had done hardly any work. It had some sort of coupling on
The harmonic balancer so i presume it came out of a mixer or a garbage compactor. Replacement blocks never had an engine number.
If your block was U/S they would stamp your old number on it
. I just stamped my old engine number. Mark
Hi Mark, I bought a 237 from Gleemans and it was ex USA, it had no eng #, it was in really good nick, it was tilted and had rear mounted turbo and other parts which I'm sure came from an MC or something. That engine still runs nice and clean, it is in my tipper. Regarding that R with the V12, It was a 700, it had 2 hole steel Budds on the steer, I think they might have even been 24.5's.. Jeff .

Hi, I'm pretty sure it is pure Renault. Regards Jeff.HiI have just bought myself a new (new to me) horsebox truck. It was sold to me as a 1988 Renault Midliner but since looking on the net at some pics it looks alot more like the Mack Midliner to me but i am a complete novice when it comes to the models of trucks ........what do you think??

Hi Russ, 45 is a Cummins 'NT', I found that somewhere in reference to an F745. Regards JeffHi all,Another engine question...Was looking at a DM845SX today. I searched the threads here, and have many engine codes written down, but not a 45. What engine does 45 mean? Thanks for your help.
Russ

I was wandering what happened to that R 700, was it 1 of Hayes' trucks ?

Hi Grant, I'd be interested in most of the leftovers you mentioned, including 'F' parts. Let me know what you want and we can go from there. JeffHello, I am not doing anything with the engine but pulling it out and selling it and the 18speed quad. and the flintstone cab and hood can go to! once there out I can drag the rest over to workshop and relocate the diffs 24 inches back from there current position and drill new chassis holes, then strip the poor thing bare.Grant
E-9 Paint Colour
in Engine and Transmission
Posted
John, the first E9's & E6's were that salmon colour, I think when they went to Econodyne they went that light blue colour. I think there was a change in the shade of grey sometime after it was introduced. When I was looking for it a guy at Mack in Brisbane said that the colour was a Dulux colour called 'Avil Grey'and later changed to just 'Anvil' and you could buy it at any hardware store as small as 500ml, I bought 1ltr. I'd like to know the code for a thermodyne 6 in the late 60's early 70's, b4 they went to silver for a thermodyne it was an aqua blue colour. Any ideas would be a help. Regards Jeffro P.S. I think when they went to 500 hp they went grey
