The Mack has finally arrived on farm!!! But it has issues! We struggle to get it off the truck, but we do eventually get there and show you around the truck and of course take it for a drive!
X MK II operator here. The starter needs pulling down to find the issue, its bypassing air to the exhaust (that inch n half outlet) which not only dumps air but reducers the starters torque and revolutions.
Youd have to check the current pto will work at high engine speeds, as it may be geared for idle like work being that its a fuel tanker. But probably a way around it. You could also consider the 2" davey twin impellor pumps with the 13hp honda on them, you have a backup rope start, for the $$ your talking you could put two big honda/daveys on there and have pretty impressive and simple pumping setups, big bonus you have two pumps, if one dies , you have a spare. Very impressive compared to the old GX160 firefighters we are all used to. Your diesel option though is nice not needing to have seperate fuel and fuel tanks on board
Re your fire fighting pump setup, why not hydraulic drive your existing pump from your truck engine? You already have a hydraulic tank and your truck engine is large enough. This could save considerable weight and space as you already have some hydraulic setup on the truck.
What you are trying to screw in is just the muffler for the starter, does not affect operation. By the sound of the initial start there was enough air to start. It sounded like the fuel had run back to the tank from the injector pump, needs pumping up with the primer pump. There is a check valve where the air goes into the starter tank which should maintain starter air when all other air is lost. I'm sure there will be a Mack man down your way that should be able to sort that for you.
G'day JH great ol truck ya got you would have to name it MACCA or H2O or Squirt glad you are happy with it stay safe Henry had a grin on his face like a kid in a candy store.
Hi jh you can put taps on the tank for the two small air lines, get sum new air lines made up turn taps off when not in use, you may need to pull the big air valve off on the bottom of the air start tank and clean and put some rubber grease on the O rings, you may also have fuel draining back from the injector pump, you may need to put some new air lines on it, have a look at the air start silinoid of its leaking air
The smiles says it all on the test drive, great stuff mate

Extra sockets and tools don't stop working even rusty store them for a rainy day ✌️

Great truck!! Going to enjoy watching you have fun with it making it a badass fire truck!!
Check the air start tank for a one way valve so it doesn’t loose the air for starting 👍🏻👍🏻👍🏻

The pump for the fuel should be able to pump at around 1000 lts a min if it any good. That will run a good canon. 👍
That part you picked up off the floor is just the muffler for the air starter, sometimes they clog up with sh1t and some people love how loud they are
Can put tap on air tank so it don't all leak out before you need
❤❤❤💯💯💯

You’ve got everything all set up to run the existing hydraulic pump it’d be a lot simpler to purchase one suited to the job and swap it
Looks like it will be a good fun project to set it all up.
Convert the starter to electric start
👍👍🇦🇺 should ov grabbed as many ov them mack's and mogs az you could get ya hands on 👍🇦🇺
Air start trucks can have absolutely no air leaks , good luck with that.
wooohooo its here
