Are parts available?

Driveline parts will be readily available.

As has, been mentioned Engine is 8.3 Cummins either Roadranger or Allison Transmission & Rockwell (Meritor) Steer & drive Axles..

Cab Parts will be hard to get, Though.

PS: were also sold as Kenworth K300.!

I'd leave the E7 there as a Tribute to your Grandfather. He managed to do 2 Million Miles with It the way It Is..So why Change It..??

But at the end of the Day.. It's your Truck, Money & Time, Do whatever Floats your Boat...

The E9 & Scania V8 shared a common engine Block Too..

Welcome to the BMT forum.. This old thread may help you..

I have a 2001 quantum the Horton fan won’t go off but what is confusing the ground wire has power in it. If you push the test light into the earth wire at the selonoid it lights up but gives it a earth and stops the fan. Any ideas?

Sounds like an Earth Issue to me. get a Multimeter & see the earth wire has a Short in It..

Maybe disconnect/remove existing earth wire & run a new one..!

In February 2020  Dean Bestwick The Vice president of Sales & Marketing  of Mack Australia took on a Big role with Mack in North America.

If he's given the same sort of Autonomy he had here in Australia expect big changes & some Australianized Features on New Macks..!!

You might have to wait for the Virus express to Leave & some normality return first though..

I wonder how the air cooled engines worked out?

They worked out Pretty Good..

They were BIG power in there Day.. Only thing was you HAD to idle them down properly or they'd grab a Piston..

Most owner Drivers used to carry a Spare Barrell Piston & head with them all Loaded up. they had access hatchs to the Crank & you could change a Barrell ect. over in 20(or so) minutes I've been Told..

i wonder what it has for power?

At the 2.40 mark you can hear that V8 Cackle I reckon.. But Have been wrong before (Just ask my Wife)

I've no idea if something like This is Available In the U.S.A.  ..

But I've fitted one of these to a Truck & It makes a HUGE difference..

Is the Transmission end of the Cable rounded off or still has the Drive pin On It..

Also is there a Ratio Adapter something Like this on the Transmission?? they can & will fail..

So here's a girl in a shopping cart -

 

I think She'd be Barely Legal.. Otherdog..

Those old 300's were a good Motor. Dad had one in a F700. It got a bit Tired so he put a 351 in It. .

All he gained was the V8 Burble.. Didn't seem to Go all that much Harder...

My Monies on It being a BITZA built by a Retired Truck Driver...

Most likely a Mack Chassis & running Gear with the Camper Body Grafted onto It.. But just a W.A.G.  on My part..

You Should be able to make a Bendix To Flo 750 Compressor Fit I would Think..

Some opinion news sources here have been highly critical of Australias response

Media Organizations the World Over are absolute Experts at Cherry picking, & Selective editing things to suit Any Narrative they Want..!!

Don't believe everything the Press Tells You.....

EDIT: Here in Australia Gleemans used to be the Australian distributor for P.A.I.  Parts.. But there've been taken over bought & Dumbed down. Not Too sure who the Aussie distributor is Now..

Wow-any clue on distance of the  haul?  Any clue as to  how many man hours it takes just to remove the boom/bucket?

I found the Pic on an Australian heavy haul page.. I think It was an Internal site transfer on a Mining Lease.

They mentioned that; the Gross Weight was 670 metric Tonnes..

I've NFI on your manhour Question.. Sorry.
