The oil lines and updated parts did help the Jacobs brake after the engine got some miles on it.
-
Even when new, the ETECH Jacobs brakes were so weak that the later trucks had the option of turning on the air fan when the engine brake came on to help slow the truck. This parameter was turned on in the VECU software, we rarely turned it on.

No luck here. Part number is correct but comes up in red and won't let me search for it at other dealers
-
You got last six of VIN? I can do a dealer search and see if any are laying around at a dealer somewhere

Anthem fuel tank specs and measurements
Mackpro replied to Mackpro's topic in Modern Mack Truck General Discussion
Does anything Volvo does ever make any sense? That's my only answer. Lol. Actually someone told me the reason but I forgot, -
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

2000 ch613 heat gauge
Mackpro replied to svigarfarms's topic in Electrical, Electronics and Lighting
Check the ground breaker next to the wiper motor on the fire wall. -
I can pull the specs if you got a year model?
-
What year and 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

Anyone doing full deletes on MP8s yet??
Mackpro replied to bulldogfarmer's topic in Engine and Transmission
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

Anyone doing full deletes on MP8s yet??
Mackpro replied to bulldogfarmer's topic in Engine and Transmission
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
-
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
