So another late night which means Waffle House for supper, OH boy,  anyway zoom in and the cook who has been there for 25 years is cooking, they say he has been there longer but I know for sure 25 years cause that's  how long I have eating his cooking,  anyway some yahoo puts some RAP sh*t on the noise box, so I put on my look of disgust and manager wants to know what's wrong, As nice as I could I explained that if Christopher Columbus is offensive than that SH*T is offensive to me, they unplugged the noise box and I ate in peace except for some whispers from the dark pigmented life forms, seems they thought that was unfair, my only comment was how does it feel ???? score one for the white boy bit*h. 

Welp, let’s flip this pancake again to their side? Sir Mix-a-Lot’s rap tune “I Like Big Butts” directly applies to the midnight, waffle stuffing, munch-a-thon folks? May have been perfectly appropriate music genre? To quote Fred...... Just say’in!

We used www.ksfuel.com. Did well on those pumps.

A 30-06 would reach that far.

That’d be nice medicine for it. Too many....everywhere. Got called in Monday night and one shot the company fence then ran headlong into my grill. I dug this old pic up to tell them they need to open a season on these crazy road 🐐 goats. 

2 years ago we had one run into the facility. Got turned around under the paper machine & started raising hell in the maintenance basement.

Might have been some warmth coming off the chips.    .....Hippy

Sometimes the wet bark piles start on fire from decomposition. Gets exciting. 

From winter. Not sure what he was doing there surrounded on all sides with equipment, buildings and a river? Didn't seem to be worried. Taking squatters rights on the wood chip pile.

Yup, they’re hearty folks. Don’t mind riding on a steel hump. Much of the 90’s fleet had air ride with the sleeper units and 48’ loader trailers. Landing pickers.  

Keep in mind these guys considered an air ride seat inside of an air ride cab to already be a little too luxurious in comparison to the forwarders they used for the previous 30 years. Before bio mass collection the trucks would run right over the downed tops. Bags are flimsy, low and vulnerable. If you had an air bag suspension you’d be doing one bag a month because of tooth pick attack. Now they chip the whole tree and the stumpage looks swept clean as the kitchen floor. That’d be my guess.....they expected to pick off deep landings and didn’t want to deal with bringing suspension balloons to the dart 🎯 party? Other thing was axle cracks. The single-point weight displacement of a spring pad usually cracked the Mack axle tops on the off road trucks. Camels had better weldment style receiver and rarely cracked the housings.

I’ve seen lots of bad deletes on Macks , seems very few work out great. The last one was where a delete was done and a export model data file was installed in the engine ECM. This sounds like a great idea but the export models don’t have  a VGT turbo, they have a standard turbo. The truck would barely build boost  because the VGT turbo was not being command to move abs build . I had to remove the turbo actuator and manually move the arm on the turbo and test drive , if  I went to far it would over boost and backfire through the air filter and derate. Once I got it figured out I built a wedge spacer and put it inside the turbo actuator to hold the arm in place . This was years ago and don’t remember the actual position of the arm . 

Love it!

Be tempted to machine a little adjuster screw to set VGT travel limitation and a “give’r hell” cable, with a hand grab T-bar, for the big hill climb mode! Pull for full boost and slam it back home when the EGT’s hit 1,400 degrees.

Wow. Couldn’t imagine having that much money and equipment to be able to buy a new machine and let it set. They say the 3rd generation of a family business usually fails. I assume it’s because the 3rd gen never say gramps and gram bust their butts to make a go of it. So in the 3rd gens eyes it’s always been easy so just sell it. 

He's retiring. As I recall they never bought a truck inside of the Tier 3 emissions (or higher). The newest I recall were some 460HP E-Techs from the early 2000's which they used to tow 98K of wood chips. Those he started selling 2 years ago.

Tires got hocked, looks like recaps, the one still has a sticker on the cap? Bright side......at least new recaps! Funny how the condensate can rust the plate & mount.

Guys I know from the dealership days. Loved Mack. Use to spend the end of year $$ on a new truck or wood processor and let it sit in a showcase shed for local parades or as a "just in case" truck. They must have had one of the millennial grandsons post it, he clearly can't spell Mack (Mach). 50 miles on the truck.

I had one customer with a V-Mac II come in during the LS transition with a failing injection pump. I had it staged to R&R over to K&S Fuel for a rebuild, he didn't come back for 6 months. When he finally came back for other work I hit him up to find out what was shaking. He had started adding lubricant to the fuel and said the rack stick went away. That's the only instance.

Once I drank a pot of coffee and read through the most boring engineer interpretation I could find on composition of Low Sulfur fuel. It acknowledged the fuel has been "dried" from the process and mentioned lubricity additions to the fuel (per manufacturer) as compensation to make up for the anemic lubrication character.

Yup, I ran out of space, unable to clear. Barry was kind enough to go in and manually adjust.

Do you feel its making the same power as the etech at a 400hp rating

For the heck of it I overlaid the two books with the torque/HP curves. They’re exact. 

He has an E-Tech and a V-Mac II. It’s not the same engine, but is an E7 platform....for the most part. 

That’s a million mile base engine if you properly maintain it. Arguably the best PLN engine Mack made. 

In their time a very reliable motor, now add 23 years later........mmmm, gremlins we never saw could arise in the aging of its electronics, sensing, low sulfur diesel, etc. I’d buy one though. Smooth power, nice idle, softer than the E-Tech by far.

all but one of the 8ll trans trucks i ever drove had this problem. 

i think the 8ll is the absolute worst trans ever made.

10, 13, 15 and 18 speeds never had that issue.  

 

I need to put my wallet in Wild Dave’s mouth so he doesn’t pitch a fit and bite his tongue off when he reads this thread.

I think someone said 2002 was best a while back, don't know why. I have an 02 350hp with 300k and the thing is mint. Will probably blow up tomorrow because I said that lol

In the late 2001, 2002 and early 2003 Mack had figured out most of the base engine issues. When Tier III hit in mid 2003 it was more emissions and other issues to hash out with emissions. 

The mid year 1998 1/2 E-Tech engine intro was also a good showing.

We use donaldson  as a second line and sell them for those who don't want to spend the bucks on genuine Mack I have seen them come with threads not there ,However seen it happen once on the Mack filters too! Shit happens! Automation!

Is OE Mack staying competitive? They use to give them away?

I only buy OE for the Volvo’s oil&fuel. $21 for an OE oil filter is nearly as cheap (+/- $2) as NAPA WIX.
