Hi Adrian, I've replied to your message twice now, it still tells me no messages sent. Last message this morning 17/feb jeff.

Hi Adrian, Steve's answered it for you, I have noticed though some macks will be stamped as RST, but appear to have a heavyweight rear end. In the 60's thru to 80's to me an RS was double splined rear axles, i.e. 40's or 44's. In the late 60's alot of these Macks were only 40,000lbs rear, but people say they are 44,000lbs because they have a cast pedestal and double splined axles, I'm not so sure. Jeffro.

HK, I take it the box I have, X1070 is overdrive in hi, the '0' on the end. Jeffro

Hi Barry, you managed to get a copy, thats great. It certainly was a nice truck, be great to see it looking like that again. G&L Stevens ran a tanker operation out of Darwin. Their 1st Mack was an R615RS Flinstone. There was a Cummins powered R700 with a fibreglass cab, it may have been Noel Buntines, he had quite a few. Brambles Manford had some aswell. Wettenhalls in Melbourne bought 4 R700's, 1 had a 320 coolpower, the other 3 had 350 Cummins', the only difference in appearance was the 320 had twin cleaners. I think they all had Mack 12 spd Maxitorque's and 34,000lb rears. I'm workin my way round this computer thing, I'm at the stage were I want to post some pics, just got to get it together. regards jeffro

Thanx Michael, for a moment I thought I had a 12 spd, but the no airshift had me confused. I hve since found a pic from Nov 68, a 237 with the same looking box, it says TRDXL107 with 'creeper' gear. My 1960 B 61 T is an ex 'WESTERN' unit also, it is in a very sad state, but complete. Regards Jeffro .

Barry, a Maxitorque 5 spd is pretty easy to ID, its a triple countershaft box so when you look at it from the rear it is triangular, flat across the top. Looking at it on the LHS like a passenger in OZ it has 3 sections, i.e. a clutch housing, and a 2 section main case, on the side of the front main case there is a flat area where the model # is stamped, just above that is the Mack logo. The rear case has 'Mack MAXITORQUE TRANSMISSION' cast into it. The model is TRL107 or TRL1076 or TRL1078. It should only have 1 gear lever and nothing else. The model # might only have L107 or L1078 I'm not sure of the changes made to the 5 spd, but you might like to find out if it is about mid 70's or later to suit your era. I think you might look for a TRL1078. If it has an extra case between the clutch housing and the main case, or if it has 2 levers or airshift cylinders it is not a 5 spd. Hope this helps you a bit, Jeff

Thanks HK, I was told it was a 6 spd but got confused by the extra case and no airshift to the rear. Also no shift pattern lable and no engine. Thanx Jeffro

I have a 1968/1970 Mack R685RS, it has a Maxitorque, it has 4 cases, i.e. clutch housing, front compound & 2 main cases. It has 2 gear levers in the front compound case. There is no shift instructions in cab and has no engine so have never been able to drive it. I beleive the engine was a 237 maxidyne. There is no airshift on the box just 2 levers. The model on the side of main case is X1070. I have a D107 10 speed and an X107 6 speed. I'm presently going thru my Mack manuals to see if I can fathom it out . Thanks for any assistance you might be able to provide . Jeffro

Hi Barry, yeh it would be great to see one of these monsters preserved or at least saved. They were designed and built in Brisbane by Macks engineering team, headed by Max Evans, the rear end was an SWD69, 80,000lbs bogie. It would be good to see more pictures of them as they are now though. Jeffro

Hi ,I'm into that stuff, its great to find this sort of info on an old truck. Regards Jeffro

Barry, I looked for your R767RS, it was in truckin Life V1 N4 as rig of the Month. Yes it had an NTC 350, 5spd Maxitorque main and it says a Spicer 12-416 Aux. I think it should be 1241 C. It has the 2 Mack step tanks as well. It says the sleeper is 36", it is a Mack box, I think built by Denning. jeffro .

Hi Barry, that Mack looks slightly familiar, the colour and the extra fuel tank, I think it may have had a sleeper, about 40". It probably had a Mack 5spd main with a 4spd Spicer. Regards Jeffro.

Hi Thad, the 88 code is for an E6 350 , a Detroit would be a 7X I think, 73 is 8V71 I dont have an engine code at hand right now. There was only a handful here in Australia, I've been told of 2, the same goes for the Cruiseliner, mostly Mack or Cat. There were more Superliners with Cummins than GM. Regards Jeffro

Hi mackattack, the V8 in the C & B was the 1st V8 , the END 864, and also in the R 600. I'm pretty sure the ENDT 865/866 was'nt available in the R 600, only the 700's & 800's regards jeffro

Hi Andy, B 613 is an END 673 T , not to be confused with an ENDT 673 C known as a 'C' engine. regards Jeffro

hi, dont know what year but that grill was used on fire apparatus, and it has dual ignition, so its a fire truck, and the plate says MOD.....75X, so its a mod 75, that is 750gpm, thats what i reckon , regards jeffro.

G'day Milo, yeh all fibreglass bonnets have vertical shutters, there should be 18 vanes, 'Kysor' is the brand name, you pickm up at Gleemans, if they come of an R model with surrounds they will bolt straight to your rad, if they dont come of an R or another brand of truck they might look right but the vanes and frame could be a different size, vane length should be 650mm. For the trim you might have to find a damaged bonnet . Hope this helps , regards Jeffro.

Hi Russ, the U model is basically an R model with an offset cab. The DM is a different chassis altogether. Hope this clarifies a few things for you. Regards Jeffro

Hi Grant, i havent been able to get on here for a while to reply to you. The reason your FR has a hole in the LH chassis rail for steering is because it is an R model chassis, if it was an F model chassis there would not be a hole for steering and your front front spring mounts would be totally different from L to R, what you have is a standard Aussie built post 71 'F' model which is actually an 'FR700R', i.e. R model chassis. Regards jeffro.
