    Vlad the Thermodyne motors can be driven like a Maxidyne just fine I have had problems with the splitter on the 12 speed once grossing 90 ton drove 3000 km  with just the 5 gears and up some big long climbs they the Thermodynes that is will lug right down to 1100 and I just kept a eye on pyrometer and the Thermodyne would hang on at 12 revs for hours at a time with out it getting to hot on the pyrometer so I just let it lug 

    So I guess what Im saying if my old bucket of bolts can hang on for hours at a time grossing 90 ton I reckon bobtail or even just a normal single trailer it would be fine with a five speed 

    Before I went changing anything I would drop the nine speed apart and see whats crook in side they are fairly simple transmissions to work on and theres not a lot to go wrong 

    Roland great video mate I find I get much better air flow in the cab with only one window open as I think both windows the air pressure seems to equal out and I end up with bugger all air flow

    G'day Paul,

    Yes I agree that one window down seems to work better. I tried two partially down on the way back and felt hotter, even though the sun was pretty much behind and to the left.

    Yeah, the RR probably only needs bearings and shifter work, but I like the taller overdrive of the Mack box compared to what the RR can offer. It'd be nice to get 100kmh...

    G'day Vlad,

    Thank you for taking the time to reply in detail :thumb:

    I have the same problem on rough roads. My foot pumps the throttle and makes it much worse, especially in the first 5 gears.

    Last week I went for a drive to fuel up at a new truck stop near work. It's was 34°C in the shade. So I grabbed myself a small can of Coke Zero and then instead of just driving the truck back to work, I drove to a Gleeman's. They're a truck spare parts and wrecking yard about 45 minutes drive from where I work and about 20 minutes from my home. It was the first time I have driven the truck on a hot day. PHEW! I had both front vents open, as well as the roof and drivers side bunk vent. Stopped at traffic lights, was like being in hell or Pizza Oven as a mate of mine calls his F model hahaha. Once moving the air flow was quite comfortable though.

    Mine has a worn out 9 speed overdrive Road Ranger. I have been experimenting and I now only use five gears when taking off from traffic lights with the Maxidyne. 2nd, 4th then split to high for 6th gear, then 8th, then 9th. I have to drive it like a 5 speed Maxitorque and wait for the revs to drop on each gear change. Otherwise I can drive it like a hot rod using all 8 (not low). It's impressive if I get it right. Embarrassing when I don't hahaha. I think I want to change it back to a 6 speed over drive twin stick Maxitorque TRDXL 10780 as the overdrive will be .62 with 6.34 diffs...

    Here's us on our wedding day. I didn't know my lady was filming at first. I thought she was just talking to me Hahahaha...

     

    Keep warm over there mate

    G'day Vlad,

    She's a good looking truck. Does it ride well with the air bags? Tell us about the engine, transmission and diff ratios please. 

    Looked like a nice drive home, but perhaps a little cold hahaha.

    All the best

    Thank you for sharing this story and the picture.

    I don't remember you previousely mentioned you bought that rig.

    Seems cool you could ride your lady there. Hope it was a lot of fun.

    G'day Vlad,

    Good to hear from you. 

    Did you ever read my story of how a purchased my Mack and drove it home?

    I ended up buying the truck mentioned above. Not from the guy that "restored" it, but from a fellow Mack enthusiast in Kalgoorlie that was hoping to put it back to work. Due to a growing business and mine sites being reluctant to allow a near 50 year old truck onsite, he had to let it go and buy a newer truck.

    It's far from restored. It's tidy on the outside and pretty much as it finished it career on the inside. She's a '68 F711-RST. Cross over steering shaft. Originally a long wheelbase rigid for Wrights Cattle Transport fitted with a C motor, quad box and 34,000 rear end.

    At some stage the wheelbase was shortened up into a prime mover, 44,000 rear end fitted with 6:34's. A 9sp over drive Road Ranger. The motor is stamped as a C, but it's actually a 237 Maxidyne.

    The original hard seat base on the drivers side (RHD) has been cut out and an old Mack suspension seat fitted in it place.

    I recently removed plywood additions to the centre console as most of the extra switches and gauges aren't connected. I also replaced the Push Pull Park Brake Valve as it was leaking profusely in the parked position via the foot valve.

    She holds start air for about 4-5 days and starts first go, even if parked for over a month.

    My short term goals are to tighten up the gear linkages, soften up the rear Spring packs and refurbish the semi custom cab suspension that was fitted at some stage. I also am hoping to fit a suspension seat for my lady...

    All the best

    Tire pressure for a hobby truck. Looking for advice.

    G'day mate!

    Quite an interesting point. Did you do 30 pci with load? Or with an empty trailor? Sounds impressive anyway. I think your camelback was too pleased initiating horse riding[emoji4] Thank you for sharing experience.

    G'day Vlad,

    It had this tipper body on with 2 spare tyres in it only.

    2ff9db98d0169c95110cf597c5be9f81.jpg

    So I estimate the total load was

    I did the same as you. Day 1, 90psi to 60 psi which didn't produce much of an improvement. Day 2, 45psi with a noticeable improvement, but 30psi was the best so far. This weekend I'm going to test 25psi on the way to the workshop.

    Oh yeah, I'm a rodeo rider now with the camelback lol.

    All the best

    G'day Vlad,

    On my short wheelbase F model with 44,000lb camel back suspension, I was advised to run between 30-45psi. I recently drove right across Australia 3,400 km's like this. Same on good roads it was fine, but as the roads became worse I let the tyres down in 10 psi steps every day. The best ride was at 30 psi cold, measured in the morning before driving. All 8 tyres on the drive are 11r22.5 Aeolus also. 30 psi on the rears made the tyres contact patch look similar to the fronts at 90psi.

    The tyres did not get hot, even on warmer days of 25°C. 

    I hope this helps.

    All the best

    F Model 711? Central Australia

    in Truck Stories

    Posted · Edited by Retro Racer

    40 years later to the month, I purchased this '68 F711 in Kalgoorlie and drove it back across Australia to Sydney.

    Hell of an experience and had some dramas along the way, but with some good luck I managed to overcome my problems roadside by myself.

    Hey ianoz,

    Thanks for sharing the pics. I particularly like the red R model and Flintstone.

    Re the bull bar tilt, there's a box section fabricated behind the bar and bolted to the web of the chassis. They usually have a very low hinge point well below the chassis line and on the red R model you'll notice the two eye bolts that locks the bar in the upright position to the box section behind it.

    I personally prefer the original bumpers, but the size of our wildlife and roaming cattle necessitates the bars here.

    All the best

    Those cabovers are of the same kind as the one had front bumper thrown out near the lake in Russia.

    Although somebody noted Australians built them with R-model frames. Or some bunch of them.

    I think they built them with R model chassis so the steering box would fit on the right side and not be chain linked :)

    All the best

    Welcome aboard! I took a quick look at the National Road Transport Hall of Fame website and will have to check back when I have more time. It looks like a fun place to visit and it 's kind of you to volunteer your time for the cause.

    Forgive my fellow BMT'ers for some of the silly questions, they get carried away sometimes. There is something I've been wondering about, however. How do you folks down there keep from falling off the bottom of the earth?

    It's because we get so many crap US TV shows here that it oozes out of our sets, sticks to our feet and keeps us fastened tight to the planet ;)
