I think they would be, with MP 10 at 685 hp and 2300 ft lbs of torque, I reckon they would sell like hot cakes except for one major problem Americans seem to like dumping their trucks on the ground to give it that long low sleek look, modern Australian Macks are up high and your face toughness Paul

They worked fine in hot climates and cold, they certainly were well regarded in Australia by most that had them, from what little I know the biggest issue was dirt and dust build up on the fines etc towards the rear of the motor If kept clean like any cooling system they were a million mile motor, the diffs seamed to be a common weak point Paul

WOW, now thats some serious bling there you have going on Paul

We dont call it Veterans day in Australia. We call it remembrance day and the day is like pretty much any other except everthing stops at 11.00am for a minutes silence Apparently every country in the Commonwealth calls it remembrance day and US is the only country that call it veterans day Not matter what we call it we are all in debt to the people that have and still do give up everything to protect us Paul

It's been a while now since I rebuilt mine and I seam to recall now that you mention it that I couldn't get a close enough match with the O rings and they gave me grief so I went genuine, either way you'll probably okay as everything on mine was pretty worn out Paul

Well I'll be buggered, yes I am officially stunned, not really speechless rather just stunned Here was me thinking I was the only truck nut ( other than Ken thomas) that is also a train nut Turns out that Im not the only fruit loop in the world Now that amazing discovery is out of the way, may I just say WOW Thats amazing, amazingly big, amazingly ugly and amazingly beautiful all at the same time, well done to all involved and I'll be watching this space Just did some googling to try and get some perspective on this loco and compare it to something I can relate to Australias largest loco was Heavy Harry or H class Victorian Railway's loco Heavy Harry weight is 264 tons and a tractive effort of 55,000 lbs C&O 1309 weight is 291 tons and a tractive effort of 98,300 lbs Thats quite impressive when I consider it only weighs a extra 30 tons and has probably 40% more power Even more impressed is that both survive and this would never of happened with out the many thousands of hours volunteers donate and their extremely understanding families Well done to you and everyone else involved, you should be very proud of what you have achieved Paul

Welcome to the forum and yes these jokers all love photos so dont be shy now 😉😉😉 Paul

Welcome to the dog house, those CH Macks still look really modern to me, thats I sign Im getting old I think Hope you get your issues sorted and get your truck out and about sooner rather than later Paul

Truth be known its probably nothing Things I would check are, Diff lock if fitted, is it disengaged Wheel nuts as mentioned Elephant ears are still there and working as they should And if the trunion is brass bushed make sure all is okay, I guess the same goes if it's rubber bushed Paul

Ot cant be to bigger the door not opening fullt as the air cleaners on a B model are on the drivers sude in Australia, hear plenty of complaints about lack of cab room but rarely about access Paul

Dunno the kit number, but for the few dollars it was I just get them from Mack Paul

Here go the next part to enjoy or not, seeyah Paul

First welcome to the forum I think Joey and Mowerman are pretty much on the money My experience with doors and windows of any brand are fairly limited The R model is more of a head challenge at first than it actually turns out to be Once you have it out on the bench it really is very simple to work on compared to most other doors in cars etc The key barrel has to come out as Joey mentioned and the clip is on the inside rear lip of the door and slides rearwards about a inch, the barrel then pulls out from the outside, the clip then comes out the rest of the way The whole window and inner door skin and regulator comes out as one I think we have covered everything Paul

More than you will ever through at it, over 2000 ft pound of torque comes to mind for some reason Dunno what but I feel its around 2200 ft pounds Paul

T model Ford was probably abad example now I think about it Horse and cart maybe And as you can tell I definitely wasn't telling lies when I said that I had never driven a model T Paul

I hope you have ear plugs and no loose fillings in your teeth lol Wont be able to sneak up on anyone in that wild machine Should be interesting when done Paul

If we are honest, truck drivers today would struggle with anything more than a Roadranger, thats not knocking todays drivers in anyway, it's just industry standard today and even Roadrangers are slowly fading in place of semi automatic and full automatic transmissions Most of us would struggle just driving a T model Ford with it's three pedal transmission, or at least I think thats what it has 😐 😒, dunno as I have never driven a T model so dont know for sure Paul

So if I'm reading this correctly, this truck is 1987 model and the box mentioned above is very early gear box Would this early gear box even of been available in 1987 ? To me 1987 is just yesterday and yes I do realise it is 34 years ago but very early Maxitorque transmission to me would be early 70's Paul

Dunno, you know as much as I do, but yes has a RoadRanger for sure Most truck drivers even the 80s wouldn't of been to successful driving twin sticks so just to keep it practical and for parts like most Macks the quad box would of been removed Paul

Do you have all the remnant parts, maybe if you take some photos of the part numbers stamped on them someone on here can find whats going with the original box, as in what it actually is or modified to be if that makes any sense Count up the teeth on the gears and see what they are and then we can work the ratios out from that Paul

Okay then Well the maths doesn't match the information, so if it was mine and its not so probably disregard Its time start sorting the fact from the fiction Correct me when Im wrong, you have two transmissions plated the same and looking the same on the out side ? What I would do is try to find out exactly whats going on and take all the guess work out of this The transmission thats out and sitting on the floor I would put it in each gear and count revolutions of the input shaft to do one output shaft turn This will give you a really good indication of whats i your original box The one in the truck is a little trickier, jack up the ass end and with the help of couple of people, one underneath counting the tail shaft and one counting the motor turns on the harmonic balancer and the last joker sitting in the cab turn the key Mark the tail shaft and the balancer with a paint pen and do the same, wind it over until the tail shaft has done on turn and count the revolutions ojf the motor This will give a really good indication of whats going on as all any of us are doing is guessing at the moment Paul

Well at least thats what this bloke Des reckons, kinda gotta agree with him Paul

Dunno if thats such a big deal, I would be just thankful you could get them, hopefully they are made local but if not and even if its a bit flimsy its a heck of a lot better than a gaping hole surrounded by rust Paul

Are you sure your speed is different, as in have you had someone following you down the road or used a GPS The reason I ask is no matter which overdrive Maxitorque Mack made I dont think you will get the speed increase your saying I wonder if the gears that drive the speedo are different as the diff ratios might well be different in the truck you got the gearbox from compared to yours Did you change the speedo gears when you changed the transmission ? Paul

No backing plates on the brakes, not a big drama as most people chuck them out Looks really impressive Paul
