Be careful with what you see on the hood and headlight design.  I see some paneling on the fenders that could be add on to screw us up from the final product.  obviously the grill is blacked out and lacking a name to hide it as much as possible. 

I remember the late 80's test CH that ran for Atomic transport up here in Canada looked slightly different then the final product but really close.

I was told 6 months ago by a Mack bigwig that crossed over to the Volvo office that the cab would remain the same size as requested by alot of big customers. that and I'm sure Volvo would save some money doing so.  he also mentioned the interior ceiling would be now open like a volvo with a new bunk.  guess he wasn't far off.  the hood looks like it may have some add on pieces above the fenders to throw us off a bit.  we will have to wait and see the final product.

I like the flat fenders looso mean

Looks more like CH fenders now.

• where's the BULLDOG?

Holes are there.  they are trying to hide who's truck it is.  cab gives it away.

So......same cab shell, new bunk, new hood, new fairings........wish it was going to be priced right and break down as much as a Mack from the 80'S OR 90'S.....one could only wish.

That is weird a mack ride busted with low miles . a friend of mine has a volvo vhd 2004 with The t ride and loves it . I've always heard positive things about t ride.

I'm sure they work just fine and that design is quite commonly used in Europe.  very few in use here in Ontario right now for rear suspensions but I heard Mack has priced them well on new orders and hope that this design replaces the camel back because the M series can be used on both truck brands.

Not very many M Rides in use yet. but I have seen 1 come apart pretty bad for a none off road use set up.  it was an MRU front end loader. rear axle had to be chained to the frame to tow it in.

Very few order camelback up here anymore.  Lots of trunion and spring issues over the last few years here.  

I got to see an m ride fail that was less then six months old on a front end loader. broken torque rods and and all.

Every mixer company in Ontario right now is ordering Chalmers still to this day. Hendrickson is your best bet in my opinion. most of the reps don't even get involved in how the customers spec is doing on the road.   they just input orders. talk to the fleet owners.  get the real story.

I have some ugly news for you VLAD. ....your truck which sounds like it was a Canadian build.

Most of the Canadian build trucks had the records stored at Toronto Branch after the Oakville plant was shut down in 1993.

Most of those files were destroyed in the late 90's when The Toronto Branch was moved and no one wanted to cover the cost of shipping the Canadian records to the museum in PA.  they were thrown out with the trash.  Sad really.

Mack corporate shut Toronto Branch down in late 2001 

The MRU computer will be programed and wired for a different exhaust after treatment system that isn't even available on a volvo product.

Not quite interchangeable. 

At best you may have a good ecu that will need to be programed to the Mack software.

We had a Raydan come in a few weeks ago where the bushing attaches to the beam split.  had to replace the beam. it was a twin steer dump on a large dump fleet customer in Toronto. I wouldn't bother with it.  plenty of other proven suspensions available. I'm starting to see more Simard twin steers coming in with helper air bags on the spring centers to the frame. one large cement customer has them on all.  that looks like mid Ontario Barrie you are shopping at.

That's just wrong on so many levels....

What happened to making things simpler?

that looks expensive

Because the passenger side of the MP/D series engine wasn't enough to go wrong already.  
I can't wait to see how they shoe horned that compound junk into the passenger side of the Mack frame rail under the hood.

Yup

A couple of Large fleets up here have made decent orders months ago to avoid having these engines in the trucks about to be built.  One customer has been a regular tester of new Mack powertrains for decades.  He has had enough of the failures in the last 15 years of product development.

I believe the use of the 3 plunger unit injectors may have to do with a principal that Detroit/Benz uses on the DD series  with an extra set of injector holes in  each injector tip.
 Detroit/Benz has them on all 6 injectors and the higher then common rail pressures are made by using fuel pressure as its mechanical/fluid advantage to increase injection pressures at the tip.(basically the same principal as CAT and Navistar's use of HEUI injection systems. its ported through the head separate from the actual injector fuel supply only being used as a form of hydraulic advantage. 
 The lower pressure is fed to each injector by the fuel rail.  The DD engines use both sets of tip ports for every cylinder injection.  Metering and duration increase for high power demand and regens. 

 On Volvo/Mack The 3 Unit injectors ( that will have 2 sets of tip ports? )will use the rocker arm plunger as its high pressure actuator (Instead of a HEUI like system) when needed on the one set of injector nozzle ports while the common rail will feed the lower pressure injector ports (on the unit injectors with plungers only) The mechanical plunger will be used to amplify the common rail pressure most likely.

The other 3 injectors will be fed by the rail only and have a single set of nozzle ports at the tip.    (I have yet to confirm this but it makes sort of sense to me)
Why Mack/Volvo will only needs 3 cylinders to do this is strange to me.

Lets see if my hypothesis is correct, as nobody at my dealer has been trained on these engines yet.

saw this one a few years ago, local truck, not seen it lately....

BC Mack

This truck is actually an MRU with an MP series engine.  It's for sale in BC. It's on truck paper.

Too expensive to convert.  It can be done, but you would be better off and cheaper buying a used 250 or 300 series Midliner which would have full air brakes already.

Separate reservoirs for clutch and brake fluid on Midliners.  

Yep polishing is on the list......still have some other mechanical projects on the Dog to finish such as longer stacks etc..... 

Decals (red but not that bright) on order.

You may notice the display engine in the picture making the rounds is missing external fuel lines to feed the rail under the valve cover.  It's not a complete mock up.  I'm thinking (and hoping) this is a bridge engine and that there is another engine currently in the works for release at a later date.

Volvo VN also offers the I shift controls mounted under the radio on the dash. It's the same key pad as the M drive. The seat shifter has its own set of issues internally and with drivers crushing them getting in and out of the seat.

On a happier note, I was told the Mack cab will not be shared with Volvo as rumors first swirled. I hope that holds true.
