  1. Yes they only make the high volume pump now . 315GC466MX is the part number
  2. 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.
  3. 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
  4. 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
  5. 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.
  6. The oil lines and updated parts did help the Jacobs brake after the engine got some miles on it.
  7. 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.
  8. No luck here. Part number is correct but comes up in red and won't let me search for it at other dealers
  9. You got last six of VIN? I can do a dealer search and see if any are laying around at a dealer somewhere
  10. Does anything Volvo does ever make any sense? That's my only answer. Lol. Actually someone told me the reason but I forgot,
  11. Mack came out with this bulletin about all the different M-drive models. Direct drive, overdrive and HD version. M-DRIVE COMPILATION.pdf
  12. 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
  13. 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
  14. Looks very cool. Probably way ahead of its time, but gives me a headache just looking at it! LOL
  15. Check the ground breaker next to the wiper motor on the fire wall.
  16. I can pull the specs if you got a year model?

    What year and model?
  18. 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
  19. 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
  20. Walker part # M100463 is what we had put on a few truck. I think it was $120
  21. 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
  22. 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
  23. Never reuse cam gear bolts on a MP engine ! LOL
  24. There is a Mack service bulletin on this. There is a new updated bracket assembly to fix this issue.
  25. 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
