on of my biggest fears when pulling with the old R600 was a flywheel or something coming thru the floor. I have seen what a runaway engine can do to a bell housing when a clutch/flywheel lets go. a cab over would be even worse. If it had big power a scatter shield of some sort would be a must.

compression test is a good start

This whole volvo thing with not offering a Mack (or for that matter their own self) with a standard Big HP north American engine to be used in a Heavy Duty on/off road Truck is pure ignorance. Name one other truck MFG that builds more extreme service duty chassis and then chokes it with poor engine power options. Even if the big HP was offered as a out side vendor engine it would still make more sense to offer it up as a option to those who demand it rather than send that customer away looking at a different truck MFG. It is pretty obvious to me that a truck with more options becomes more appealing to a buyer.

I drove a 300L that had been turned up to 2100... it had a T2060 or T2070 (cant remember) a hog on fuel but It would pull top gear to around 72MPH

Have that low RPM pump re calibrated to a 2100RPM pump.... you will be able to get to the Iowa 80 show about 30 mins faster

That is very interesting. I would have thought IH would have had a higher market share. It also seems the Mack brand is not as far off as they were 25 years ago, even though they are mostly a Volvo these days. thank you

Mack had 13% in 1990 ....what do they hold onto now?

so they make a sleeper version Granite in Australia ? is this not a repete of the failed Titan offerings here in the states?

No!

That is a very solid point and should be shared to these goons pushing for ELD. I dont haul freight but if I did I would not put up with these shippers with the appointment crap. Pay me for a days work be it sitting at a dock or rolling down the road....very simple and I dont know why drivers put up with that crap

I sleep a good 7-8 when I drive so that would work. I wonder how well it can maintain cool temps. I normally set the blower on low and the a/c to max cool. I wake up to 50 degrees some times...and Love it! I sleep better than at home LOL

I have never slept in a truck with a APU or other device that allows the use of A/C with the Diesel engine off. Im not sure I would sleep well without the "white noise" of the engine running? Regardless this is a slick way to maintain voltage and use the A/C...but I wonder how strong it is. I can see a low tree branch causing a very expensive issue.

I was thinking more of how the driver was going to feel after a day of off roading in one of those things. they seam to be a rough rider even on the street.

About 10 years ago they had a mass sell off of them. most were 250 or 300HP with automatics... a few guys picked them up and turned them into dump trucks. first time I had ever seen a MR pulling a dump box

looks like fuel tank is melted. the fire had diesel fuel at its disposal

The Donald says Klinger can go home now.......

10 years ago here in Chicago 90% of new concrete trucks were mack. With Recent ownership change of our local major concrete company's I think mack has around 50% now. The Refuse market is also going slowly away from mack as well. slumping mack market share is very noticeable these days

The superliner II that was at a company I worked for simply had the stainless breather bracket bolted to the driver side cowl with aid of a stiffener plate on the inside of the cab. it made the kick vent un usable. I have seen some superliners that had that stiffener plate on the passenger side as well. you will also want to adjust the driver door stop so that the door cant swing into the breather. again the passenger side may already have the limited swing hinge on it.

I was not aware it was available that late into the 90s

correct me if im wrong but wont a trans with a over drive final gear driving very fast rears give you very poor pulling ability. I can see how it might be better on fuel if the engine can maintain such low RPM on cruise but once you hit any slight grade you will need to downshift to get the RPMS back up?

if its a simple 2 wire set up..... from the back of the unit just run a wire from the + post over to the battery then attach a ground wire to the frame or block. after the truck starts give it some rpm and then use the volt meter to check voltage at the battery. On my R model I am seeing 13.5 to 13.7 at my batterys and about the same on the dash gauge Or just run it over to a electrical shop and ask them what they think. I know the 22SI had different options how they were equipped.

well done Larry ...Got to have fun even if you dont win it all. I have yet to figure out this kind of drag racing where you have to call your dial in time or what ever. I enjoy the old line em up and run. he who is fastest wins. I can understand having brackets where you have a weight or power class etc... I just cant follow the dial in times and if you go faster than that you get thrown out.

I noticed the hint of a RD fender as well and it also looked like it has a wheel opening kinda like a old R model. That would be cool if it they pulled it off right. I never really had a complaint about the CH cab as it was roomy. It is up there with age and really the only thing most of them lacked was a nice dash. they have improved on that over the years. I wish they would get away from naming the truck line up. For example Who names a truck after a golf ball? They should go mack to calling it a "X" Model or "X" 600. it was a much better way to denote what it was and equipped with. Locomotive MFG and most other large MFG still use that method and its easy to follow. still is a shame that you cant get big HP in a Mack. How Volvo cant see this is beyond me. Its been 30 years but to see all the Mack westerns equipped with different power and trans options really set the truck apart from a fleet spec. Sad that Mack even before volvo ownership has been shy to this market for 2 decades. Hope the truck looks good and they drop the

Thank you Vlad... I had the truck on a solar power trickle charger for the last few days. its keeping voltage at 12.5 during they day. When I started it voltage at the battery was a little higher than 13.5 so I guess its doing what it should. after some research I also noticed that my unit does not have a 2nd + post like some Delco Remy units have. the delcos have a "smart sense" option. It seams the delco units have a wire that goes to the starter and another wire directly to the battery. the delco units will self regulate making sure that 14.5 is always going to the batterys. I guess it can better see if the battery is seeing all that the unit is really putting out? The truck starts fine and in excites as soon as I touch the pedal I just fount it odd that I could see 14.7 when the battery was disconnected but 13.5 when they were in the system

First question is this a internal regulated unit or a non regulated unit. ? I think the 22si could be had both ways. Most people today buy internal regulated as its less wireing. if it is internal regulated you just need a thick red wire from the unit to the + side of the battery and a good ground wire to the block or frame. if you start the truck and voltage stays 14.5 or less you are good. if it is above that it likely needs a external regulator. Still Best to find out before. The "R" puts out 1/2 the voltage used for other stuff that you likely dont have. one other thing is some units need to see RPM before they start charging. so after you fire it up give it some RPM to excite it.
