313GC5227MX is for your truck (Early ETECH). The 2002-2003 CCRS and 2004-07 AI engines take 313GC5230MX . The AC engine takes 313GC5233MX . The X on the end of any Mack part denotes reman

EPA to rescind glider kit emissions regs enacted last year
Mackpro replied to kscarbel2's topic in Trucking News
This is good news for those going that route. -
Certain year models of the MP8 505 you can have it bumped to the 505 Plus and gain some torque. I can't remember if it's 100 or 200 ft pounds. We have a few of the Plus trucks running around here and the one I rode in was grossing close to 100,000 pounds was in no strain up hill or in town driving. If your truck has the 2 piece valve cover I think it can be done, if your trans is rated for the extra torque

Call 1-800 AIRBRAKE . The Bendix tech guys are quite helpful sometimes, plus you dont have to be a dealer to call.

Yes they only make the high volume pump now . 315GC466MX is the part number

You are correct. We would repair the o-rings on the solinoids and solinoids if bad. Add the anti-drain back screws on top of the rocker arm shaft and may be the high volume oil pump. But anymore than that and the owners usually gave up and wouldn't spend the big dollars for the external oil line kits and the upgrade rebuild kits.

Heres some new specs on the Pinnacle daycab ( old CHU model) fuel tanks specs. Looks like only round tanks and no "D" tanks listed. PINNACLE CHU FUEL TANK.pdf

Thought I'd add this new info I got on the Anthem ( and I assume all conventinal models) radio controls and Copilot. Looks like Mack has renamed the Guard Dog back to the original Copilot . Anthem CO-PILOT-P7605.pdf Anthem RADIO COMPILATION.pdf

Early ETECH Jake brakes we known to be weak or just quit all together after 500,000 or more miles. Adding the update kits, external oil line kits and the high volume oil pump would restore them from the dead and make them stronger. But at a high price and most guys around here said to hell with it and didn't install the update kits. I think I put on one external oil line kit. Biggest issue we saw was bad solinoids/o-rings and the freeze plug falling out of the end of the rocker arm shaft.

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

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
