  1. Go to donaldson's website with your measurments and see what matches up and look at the DB reduction (sound level) to get the quietest they got. We (mack dealership) order single mufflers from them all the time. We have ordered some high flow prefromance mufflers from them for CX/CH trucks with great results. https://dynamic.donaldson.com/webc/WebStore/hierarchy/hierarchy.html?section=10022
  2. We have never had to change the DPF filters on any of our Macks except 1 time when a turbo went out and filled it full of oil. Some of our trucks have 600,000 miles on them. On our SCR trucks ( about 6 total) no one has ever had to do a parked regen, it seems to do the regen going down the road and thats not to often.
  3. My thought is that the trucks around here run better in the 50-75 degree Spring and Fall. I dont expect a big drop in fuel temp but if I could knock 15-20 degrees off of a 100+ degree fuel temp it shouldn't hurt. I have already seen what leaving the coolant turned on to the fuel heater will do to MPG in the summer time and it is not good.
  4. Seems UPS is still holdin on to alot of older trucks. We just started on a complete inframe overhaul on a UPS 2001 CX612 with god knows how many miles on it.
  5. I wish I had wrote down all the specs and tips on MPG and power I heard when we had a Mack engineer at our shop. I will talk to our Boss and sales guys and see what they say. Best I remember they talked like running a rear gear ration real high and getting the RPM down as low as 1200 or just high enough to cruise down the road. I really need to ask them and write it all down again.
  6. Passenger side of engine, right below #2 EUP where the fuel line goes into the side of the block. I'll see if I can add a pic tommorrow.
  7. Mack sent me a new engine data file for your truck, next time your in we'll install it. they say no side affects at lower altitude.
  8. I'll send in a E-service to mack about it. I think there is a download but I also hear it hurts you down around normal altitudes. I'll see what they say.
  9. His truck sets all winter but I can always unscrew the hoses and put a union in and bypass the coolers if he needs it. Just wondering if it would even worth it to install it. Already got a 460 turbo, high flow muffler and a "Hot" enine ECM file installed , hits 35 psi boost but just need a little but more.
  10. The problem mainly is the return fuel coming out of the block/fuel galley back to the tanks, I think that is where most of the heat comes from. Thought I might put a left over trans oil cooler in the return fuel line and another one on the suction side. My buddies CV with a AI-427 will try anything cheap for more power.
  11. Thinking about the ideal of a fuel cooler. I noticed today that the fuel temp in the tanks were 100 degrees. Wonder if running through a cooler to get the fuel temps down would help preformance? I know the drag racers do it with gas engines. Any thoughts out there?
  12. We have seen this problem and its usually a loose wire connector not pushed all the way in at the large firewall/bulkhead connector. Its a pain to find. I'll see if I can get a pic
  13. $43.19 here at our shop. Part # 279gb43m. We usually change them once a year.
  14. First day back at work and ready to go back on vacation.

  15. Back from vaction for a few days then off for 5 more days of fun. I married a much younger girl and Ms Mackpro is a Princess (so she thinks) so thats where all my money goes. I think I replaced the boost pressure relief valve on yours, if not I know I have had it off atleast twice and checked it, Im sure I screwed it in farther and peened the end over so it wouldn't back out. Im leanin toward EGR valve or turbo actuator. Gotta go put more suntan oil on Ms Mackpro
  16. 9-2 code is low voltage to either the engine ECM or the vechicle ECM. Start from the batteries and start checking every cable and connection, Check the block to frame grounds, look at the ground wires on the side of the block under the starter, check the ground breaker (black box ) on the driver side of the firewall. There is a service bulletin on the 9-2 code that tell everything to check, I'll see if I can find it. Seen a few starters short out inside and cause this. Had alot of RD's that had the VECU mounted with the connector/ plug-in end facing up and water would drip into the VECU and short it out and turn the pins green.
  17. Cummins has their Insight program that is awesome. Mack has their VCADS/Preium Tech Tool (PTT)/ Guided Diagnostics software that I hate with a passion. The Guided Diagnostics ( how to test and repair faults) part only works on newer DPF and DPF/SCR equipped MP engines. The VCADS will work on ETECHs and ASETS ( I think, we use it only on MP's).The software is $450-500 but the computer interface is around $1000. Eaton makes a good proram called MD300, we use it on alot of different trucks, reads codes on the engine, ABS, transmission dash/heater/AC. For our ETECH through ASET (99-07) engines we still use the old and easy Mack service software and a service manual for checkin codes and repair instructions.
  18. Send an E-service to Mack if your a dealer. There was a new Bulletin the other day about dash clusters but I didnt open it. We have had no regen issues at all with the SCR equipped MP engines at our shop. That said , there probably is a "reprogram MID128" that they have that would fix it.
  19. Im heading to Florida for a week, If ya need me call anyway! On your idea on the EGR valve switch breaking the circuit , either wire will work.
  20. Yep, probably an ALT. Yours was due for one if it was an orignal.
  21. Off to Florida for a week, no Macks for a week!

      We already got a Disney Limo picking us up at the airport!

  22. IH does have a back up plan. They bought an emission reduction company that is working with a soild form of DEF (diesel exhaust fulid "urea"). This could be better that the current SCR system that everyone else is using. One small solid block of their "urea" equals 17 gal of our DEF and with a better shelf life and easier storage options. On the other had I worked on a brand new 2012 CXU MP7 395HP the other day, It was an ADM truck and the driver loved it, 7.5 MPG ( and gets better as it gets broken it) and plenty on power so says the driver (who is an old school driver from the 70's). He says the sister truck to his is getting into the 8 MPG range. It only had 20,000 miles on it but the factory forgot to zip tie a wiring harness and it got up against the DPF and got melted, easy fix and he was back on the road that same day. Had a Mack Engineer at our shop for a few days this week and got lots of cool info on improvements on MP engines that we cant see. They have been working non-stop on fixing issuses the we sometimes dont see.
  23. The very first ETECH's had a steel gear on the fuel supply pump, cant remember how it was attached (pinned, key way or set screw). Did enough cam jobs back then to notice the steel gear. They just recently started rebuilding the fuel pumps, threw away no tellin how many over the years. Took one and knocked off the plastic gear and chucked up a drill to the shaft and use it to suck oil out of my boat engine, works but slow.
  24. Whats the last 6 of VIN? Sometimes slapping some 24.5 fullsize tires on a roadtractor speced for low pro 22.5 with high rear gears spells disaster in off road or poor road conditions. I can pull the VIN and see how it was speced and what style engine it came with.
  25. Back in the mid/late eighty's before the CH came out, we sold about 25+ R models to a customer and all were sent straight to Rest-rite to have sleepers put on. I was 19 and hardly been out of Kentucky. I made 2-3 trips a week to pick up the new trucks and drive them back home. The Rest-rite factory was East of Pittsburg PA up in the hills. I remember meeting the owner/old man, we was very nice and walked me all over the factory and showed me how they did/built everything. I stayed at a little motel down the road that didn't have phones in the room so the wake up call was a guy banging on the door. Thoses we my good old days.
