Mack Technician

CB repairmen? Three!!!!!? That’s a whole’nother time and place. This is a cool thread, glad it got rolled back in.

Duty cycle type shaft breakage on the current 300 series turbo is not going to be an issue once your upgraded to a 400 series.

Engine’s breathing, no scavenge bump, but has all the exhaust restrictions holding back? You can only improve that mess. I’d do the 5” + manifold with the turbo OldRedMack, Burrens, and now Ditch Digger is installing on their 370’s. I think O.R.M. Said it’s a Borg Warner s467 he got from YTS. Only pure modification you can do to a stock AI turbo is melting it down and turning it into a different series turbo......IMO.

Joe has to be loving on Bernie Sanders for the possibility of finally moving the podcast out of his parents basement?

Good suggestion..... I could use some work performance enhancers at this point.

Disabled the 7th injector module (removed air supply), still frothy as a hot Blatz.

They called back and asked me to disable the 7th module’s air PSI supply. I think they’re reading this thread?

New housing in, still frothy as a high dollar Latte. I sent a request to Volvo, they are coming to finish the business. They want a new fuel pump put on it. Said they'll warranty it.

The low draw volume fuel system is also a big part of the issue. They do a regeneration loop for the fuel/air to go around and around and around and around without a return to tank and create little to no circulation to move the loop-trapped bubbles out. I wonder why they put the cooling plate on the ECM of these things, it’s not like you have enough flow introduction to create heat sink?

Good suggestion, i rubber tied a latex glove over the primer early on........but that doesn’t exactly pass as a real fix. I keep one in stock, I’ll throw it on and see what happens. They are cheapskates, no denial.

The dealership came and dropped 6 cups and injectors in our D13 and made no difference to the volume of fuel aeration. So now i'm back on my soap box about "330 HP engines don't blow cups" (i'm kidding, sort of). Glad that was Warranty!!!! Who has seen a MP8 or D13 sucking air into the fuel loop via the transfer pump input shaft? Other places? Cups are eliminated. Standpipe is eliminated (ran it off a bucket).

Guess that depends somewhat on when Hillary has you killed. Make sure your wife lists the ‘98 on here first.

Couldn’t help yourself Wild Dave.... 🙄

You do an oil test? Does it go away when you Rev above idle?

Haughty Newscasters trying to decide what’s worthy of an attraction? We dream about that happening here. Ice fisherman’s dream. Sit and jig while the disc does all the work. Bugger if you go under since it appears to take a couple minutes before your hole comes back around to you. Relax and hold your breath.

Mack pans can fit rotationally either direction and the sump pickup can be bolted to either front or back of the pump. There’s a lot that’s universal, so guessing pickup may be universal too. Guessing. Measure once you get it off, you’ll be able to determine fit for sure. No real advantage to a deeper pickup tube except in some off road engines.

I’d gamble they probably are the same, still good to expect the unexpected and watch for interference. When Mack started using multiple pan volumes they adjusted the oil change interval to the pan volume. They went up to a 51 quart for the AI, probably because of soot. Going on memory, but back when Mack had gray and silver filters, silver was longer service life for larger pans on AC. They also built a corrosion resistant pan ...SB211023. Or I should say “use to build”? Mack powder coated the interior and exterior then put a layer of Rhino Lining on the outside. Your corrosion resistant 28 quart for an E-Tech is 21359528. Mack also made 100% stainless hardware to go with the pan. Even the little isolator buttons had stainless rubber-bonded washers. If anyone looks that up I’d be very curious to see the price tag 💰

Your oil pump pickup may be too long to fit.

That’s a midlife crisis device right there.... don’t mess up your E-Tech. Agree, it would be fun to stick one on a more needy engine like the AI to see what happens!

I’m sure they have those basics covered... good 🍀 luck!

You check fuel pressure?

Ice Disc?

Wouldn’t hurt, and it likely needs one anyway.

Freaky how those dust storms can produce lightning. Watched a show about the dust bowl of 1935. Sand moving over a steel surfaces, like a plow or tractor, could generate enough static electricity to give you taser shocks.
