Progress pictures of the mack Quantum in Australia

[Gorilla]

Hey Everybody,

Here are some pics, lots of work gone in, waiting on new square tanks, still to fit nearly new 5th wheel and finishing up converting all the air fittings to compression fittings, tomorrow fitting rebuilt turbo, stainless exhaust, ceramic coated exhaust manifold and figure out why the wires are cut to the electric cab tilt pump (been using manual as didnt realize it had a electric one).  Interior is multi layered sound proofing and marine carpet.

It was the time Volvo owned Mack and Renault, they needed a cabover body  so they used the Renault Premium DCI body which worked well BUT there is a twist.  There were three variants from my understanding and i picked the best of the bunch.  YES its australia only models and there are flaws in its implementation that i am addressing such as the cabin is 24v while the engine is 12v so they put voltage converters under the battery box which is behind the engine.  I have since replaced the rubbish australian made converters that were giving me 20v for whatever reason with high end chinese ones (i know you may laugh but you can get high end stuff in china and these give a very clean 13.8v) and relocated it under the bed in the cabin where the ECU for the engine sits and there is ample room (thus put my amp, fuse boxes for accessories and added relay for converter which switches on with the 24v ignition switch).  The australian converters from a company called "redarc" which were used originally have a really good reputation but the company told me they only keep wiring diagrams for current models  (not kidding, my jaw dropped but the staff did give me info which wires did what but sadly that turned out to be wrong !!!), whereas the chinese company provides wiring diagrams for the old models on their website (as they should) and costs 1/12th the price of the australian brand!!!  Sadly i would like to use Australian products but 12 times the price while not providing wiring diagrams is a joke and i have worked for chinese companies in electronics and they are awesome with technical diagrams and i am not surprised they are doing so well. 

Variants:

1. Early ones had Renault frame (plus axles it seems and  tanks etc), but mack e7 engine, this was troublesome as the frame was narrower and was insanely bad to get to the air pump (this is where people say the issues with quantums being hard to work on comes from).

2. Mid version (my model) had Mack CH everything under the cabin so essentially its a CH with e7, eaton Road ranger etc and only difference is you need to lift the cabin to work on it which is no biggie as come with both hand and electric cab lift.

3. Last version same as mid version but with an ISX engine rather then the e7 (i suspect to meet polluton requirements), also one i avoided in the search as i wanted the mighty e7.

Its actually really nice and roomy for the driver and the shifter is shaft operated, most importantly is there is plenty of leg room where i find most american trucks dont (mack is the exception)......dont get me started on the Kenworth SAR, i was getting leg cramps in it!!!

Dziękuję bracie

That truck kinda looks like what an H Model may have evolved into. 

[Gorilla]

Fitted the rebuilt Turbo with ceramic coated exhaust manifold and turbo hot side, new studs, new bolts   and painted the rocker covers and jakes   Tomorrow stainless exhaust going on :)

[Vladislav]

Would be interesting to learn how that temp resistant paint survives.

Looks cool as it is now!

not temp resistant paint brother, its all black ceramic coating

 

[Mark T]

I'm curious how it is there's a picture with the injector lines on and no manifold.  Can you install the manifold from the rear with the injector lines on ?  Not an option most of us have here .

[Joey Mack]

Mark, my guess is he left the lines loosly in place to keep dust out while getting the manifold powder coated.

To my understanding it's a kind of powder coat, thermosetting and hight temp resistant.

Honestly not that much a matter of chemistry to me than a place they do it overhere. Haven't found any so far

Anything over here the cab would be in the way for sure.  I don't think there was ever anything here with an E Tech that doesn't have a hood except for the MR, and they're all packed in right behind the cab.  🤷‍♂️

The ceramic coating does work, heat, air flow temp etc. However, the work quality of the specialist ceramic workshop, the materials they use and following the right process is paramount to achieve the best results. If readers remember the Castrol Oil advertisement , "oils ain't oils". I paid top dollar to have the most reputable ceramic coating company do our turbo and manifold and 10 years later it remains in excellent condition, definitely no rust anywhere. And this company is still in business and excellent reviews.

Ues Paul, i didnt state correctly about alternators and generators.. 🍻

I got it done by a local turbo rebuilder, very reputable company and excellent reputation.  Been around for donkeys years so fingers crossed.  Not a chain but a family business.
