    Mack came out with this bulletin about all the different M-drive models. Direct drive, overdrive and HD version. M-DRIVE COMPILATION.pdf

    I got this the other day on the new Anthem if anyone was wanting to know specs on fuel tanks. Shows measurements with the round tanks and the "D" tanks. ANTHEM_FUEL_TANKS.pdf

    I get asked alot about how the Mack rear drive axles work and which one pulls and how the power divider works. Mack just came out with this new Bulletin that explains it better than I could ever. I was gonna post it in the "Driveline" section but I figured it would be seen more here. Rear Drive axle power divider how it works..pdf

    Looks very cool. Probably way ahead of its time, but gives me a headache just looking at it! LOL

    Check the ground breaker next to the wiper motor on the fire wall.

    I can pull the specs if you got a year model?

    Heres the differences in 427 , 460 and 460XT. This is for the 1998.5 to 2001 ETECH's. You can print and compare torque curves and spec's. ETECH 427.pdf ETECH 460.pdf ETECH 460XT.pdf

    Boost pressure seem somewhat OK. Kinda low though. Be sure to pressure test complete intake system. Early ETECHs had problems with intake gaskets blowing. New gaskets are steel core. The air compressor intake is also on the boost side ( pressurized) and is known to leak off boost . Adjust valves, Check air cleaner and muffler. Check fuel pressure going into block, should be 80-100 psi scan0598.pdf

    Walker part # M100463 is what we had put on a few truck. I think it was $120

    I got a part number for a Donaldson or walker ( I can't remember) that is straight through and not loud. I'll be by the shop Monday and find it

    Check the ring mount on the front of the air horn on the roof. We had a new 2018 last week that the air horn ring was broken and it sounded like the exhaust bracket was rattling

    Never reuse cam gear bolts on a MP engine ! LOL

    There is a Mack service bulletin on this. There is a new updated bracket assembly to fix this issue.

    Only on the CCRS ETECH engine . 2002-2003 year model. We went from 460 down to 427 to get rid of the waste gated turbo required for the 460 hp program. We did this to several trucks. Also we did a 2014 505 Plus down to a 505 due to the extra torque causing vibrations

    I think the EPA has started limiting the number of glider kits that are completed at places like Fitzgerald's. There was a big article about it earlier in the year.

    You have to pull the head . They come down through the top of the block, there is a special tool that installs them to the correct depth and makes sure they are straight. His is a good time to use the tool to check the other H rings for proper depth

    We had a customer take his 2011 MP8 up somewhere in Illinois And get the full delete done , I think it was around $3000. They said at the time they could only do the non-OBD trucks, which means only trucks with the 9 pin diagnostic plug. Not the rectangle OBD plug.

    2004 Z71 Tahoe. It's been a good one. We actually had 2 at the same time
  20. Mackpro
    This is true with the Mack MP engine diagnostic software (PremiumTech Tool). But with the "Grey" motors not so much. I don't want to go into detail as Mack/Volvo/EPA might change the way we do programming on the "Grey" motors. But let's say we're ok for now! Lol
  21. Mackpro
    Yep. Wife won't buy anything but large American made steel SUV's for this reason. If we were driving anything smaller , the deer would have been in our lap. We were gonna trade it in next month as we're approaching 300,000 trouble free miles on the Tahoe. Uses no oil and has been perfect.
  22. Mackpro
    Yep! Insurance will probably total the Tahoe, the glass guy charged us $177 but wrote it up like we paid $308. So we will get $308 back from the insurance company. Which will about cover the speeding ticket . Lol

    I can pull the exact data and software numbers off of the vin of a XT engine ECM and compare the numbers to a regular 460. However I'm vacation for 2 weeks and won't be able to access the system. But I might turn around and Head back home. Made it 150 miles from home and hit a deer. Took out the windshield , fender and door of the Tahoe. Lucky a guy changed the windshield for me in the middle of the night and we continued on. 20 min later get a speeding ticket , 72 in a 55 , he did knock it down to 60 in a 55.

    The XT programs are still in the Mack Mainframe for the VINs they were assigned to. So if you own a truck with the XT file in it , that came from the factory or was upgraded later and Mack knows it's supposed to be in your engine ECM , your still ok. If your ECM shorts out , you can get a new ECM programed to your original. Mack is just not gonna add the XT to anymore VINs. However , if you kept bringing in your 460XT truck with a bad ECM, the dealer can keep programming new ECMs with the XT file . Or you could have a bunch programmed ........ for spares .........if you know what I mean,

    Unplug the ecm , then install new fuse to rule out bad ecm
