Spike ? , were the heck did that come from ? Trolley valve, I could sort of make that connection, but spike ? no idea 🤔 Paul

My understanding it has only been this way in recent years and as others have said gold dog Maxidyne silver Thermodyne Im guessing this stopped with the Maxidyne and was just a silver dog for many years When the MP series motors arrived on the scene is around the time that the gold dog meant all Mack drive train I'm guessing it was a way of trying to capture the past gloryof something famous and tie it into the future Paul

Definitely a neat old truck there Paul

Maybe not all is lost yet, heads can be welded up and machined again You need a specialist shop for this but it can be done very successfully depending on were the crack is Dont feel to bad, the only people that dont make mistakes have never tried, I learnt the same way once some years ago now, my head was damaged beyond repair Paul

I'm kinda strange as no doubt most of you have guessed by now, but just sitting there on a beautiful spring or autumn (fall for you lot) afternoon in my folding cheer (lawn chair) with my esky (cooler) having a cool refreshing beverage admiring this truck in the sun would be plenty for me Sometimes things are just to fantastic to muck with and this rare beauty is one of those, so original and so straight I would count myself as a very lucky man to have something this special as part of my life Each to their own but they are only original once and can never go back to been that way once changed I hope who ever buys it leaves it as it is and just maintains it Paul

Yeah I think you just weld the remains of the hole up for the spoke and when finished redrill and tap in the correct spot I have welded up spokes before and ground them back into shape and never had a issue Swishman might know more about this than me Paul

Looks neat as a pin, what sort of weight and length are you at with three trailers Oh and does how much horse power is needed to shift this along Paul

Well unlike you blokes, I wouldn't hesitate having that truck I wouldn't change a thing, just drive and enjoy it Paul

Way way back when dinosaurs roamed the earth, well maybe not that far back but you get my drift After WW2 NR Macks were plentiful in Australia but had those stupid yanky 22 inch or 24 inch tyres on spiders (daytons) Anyway this made tyres hard to get and most had the hubs machined down to accept 20 inch tubed type rims These are 22 inch tubless Could this be a simple proven option for your hubs I'm guessing thousands were done in Australia this way Thought it maybe of some help Paul

A dumb question from me, they normally always are though lol Trolly valve, is that just used for pulling the trailer brakes on ? Or something else? Paul

Miss Maddie is the perfect little helper by the looks of it Happy times Paul

That is a well worn pedal, looking good and thanks for the update Paul

A header is called a header in Australia because up until say 30 years ago we only harvested the head And the seed drill is called a combine because it combines three jobs Cultivate Seed Fertilize Even in Australia a we call things vastly different names from end of the country to the other A landing net that is used for fishing is called a didel (pronounced die dill, I have no idea how it is spelt) in the area I farmed in north Queensland Yeah I have no idea about that one either Who knows probably Italian or from that part of the world as there is a lot of Italian descendents on the sugar cane Paul

Is it a combine or a header ? We call them headers in Australia and a combine I believe is what you lot call a drill Last years debacle ended up with some quality gear out and about A Massey Ferguson 587 pto on the back of the Fordson Super Major What a mess lol And six weeks later on new years eve we were done Paul

Looks pretty flash to me Paul

Looks like a allcrop header to me, Allis chalmers were probably the biggest manufacturer of them but I think everyone had a go at building something along those lines Paul

Thanks for that, clear as mud now Paul

Okay you blokes, I have been educated on a wife beater, to me a disgusting term but thats a whole other subject not related at all to trucks But what are slides ? Paul

Good for you, couldn't make it ride any worse lol Should be a lot more enjoyable to drive about now Paul

Maybe between running a really low pressure and removing spring leafs you might get a acceptable ride Does your back end have shockers on it at all, not all Mack bogie drives do, dunno about single drive, if you were to pull leaves out and you had no shockers it may tend to bounce a lot Should be a interesting exercise Paul

This is what I need to do to my truck, a bloke I know has a KW brute and pulls tripple road trains thru some of the roughest country in Australia hauling cattle, he keeps right up to date with his air system and he can park over night and the air hasn't dropped at all Which is quite impressive when I consider all the joins and quick release couplings to get to the back trailer and the age of the truck and trailers, they would all be well over 20 years of age My truck, 1/2 hour and we have lost plenty of pressure lol Paul

Looks good, welcome to the forum Paul

Well you buggered that up, thats for sure There is good news, you arent the first person to do this, I can speak from experience here Hopefully the head isnt going to leak, if it does leak you will need to find a new head Cast iron cant he heated like this, for future reference Drill the stud out a fare bit, fill the hole with a mig welder and build it up enough to grip onto with vice grips and it will just wind out I wish I had a better answer but you cant heat big lumps of cast iron like this and expect to get away with it Not been a smart ass just answering your question Paul

Oh okay my misunderstanding, so they are sealed bearings then, I best but out of this as I haven't seen this hub before Paul
