Your truck needs the turbo, injectors, download and the cam gear key way changed. Its ashame as you just had your cam out and they could have cahnged the key way and bumped the HP to 460. Here is a chart I made for the ETECH only engines showing the difference in engine parts per HP. I have different list for the CCRS style ETECH and the ASET-AC and AI versions.

Any certain area, my diagram is quite large, I can copy the part you need and post it here.

Last 6 of the vin and I can tell you exactly what you need. Best guess right now, you would need turbo, injectors, download and possible off set key way on the camshaft (to prevent overheating). We do alot of HP conversions here at our shop.

There could be some truth to that. The EUP pumps do leak some fuel into the oil pan, this is normal but if you change your oil as recommended it should never get to the level that would thin the oil out enough to cause a problem. There have been EUP failures that have dumped lots of fuel into the pan but your hot idle oil pressure would be so low it would set the low oil pressure code.

Back in the early ETECH days we would have as many as 3-4 cam jobs going on at the time. The newer cam kits have better roller lifters for improved oiling. Yours probably has the steel rollers they latter changed to cermaic rollers which lasted lcnger but any excesive valve lash (broken rocker arm, rocker arm shaft, rocker arm bolts or bent push tube) would crack them and they would fail as well. From what I've see engine brake makes no diffence on how long they last. Sadly it's just the nature of the beast.

I assume he was ok!

I'm ready, let me know when, I have a MP8 turbo coming in on Tuesday but can call him and have him come in another day. Other than than that the whole week is open.

Time to chrome it up, on a side note, we (Bossman) just ordered a new 2011 CHU with MP8 505HP ( has SCR) I cant wait to slap some some chrome on it.

Wow, I love it, Axle forward CH's of all years are my fave. I missed out on what happened to his 09 CXU?

It's a $1000 cheaper than a Mack/Borg Warner reman unit I could get for ya. Our turbo and injector shop we use (a great one in my opinion) tried to get into rebuilding these style turbos a few years back. They had all kinds of problems with the variable vanes sticking when the turbo would heat up and everything started to expand. I think they quit trying to rebuild them.

Thats a good price on the turbo but warranty would scare me. Let me see how much I can get you one for.

Mack parts says yes, if you order a M3 it crosses up to a M5. 12MS45M5 - Current Part 12MS45M4 12MS45M3 Part No. Backchain Description 12MS45M2* N MODULE

The newer Pinnacle style cabs (CXP,CTP,CHU,CXU,GU) are much more easy to change to the filter. It also helps to use a air blow gun and a tooth brush to help clean out the evaparator core.

Here's the service bulletin on it , hope it tell's ya what ya need to know. surge tank.pdf

To get to the filter, you remove the 2 screws in the cup holder (1 screw where each cup goes) lift up the top part of the cup holder. Then remove the 2 screws that hold the lower part of the cup holder to the AC/Heater cover/panel. Then you will see 2 more screws that go into the cover/panel, remove those as well. Then remove the 4 or 5 screws down the passenger side of the cover/panel and the 1 or 2 on the driver side of the cover. The cover will come off, ( the cover and unit has a alinment pin in the bottom that go over each other) then you can see the blue screen/filter on the passenger side of the unit, pull it out and wash it out. Kinda a pain in the butt to get at but when clean makes a big difference in AC performance.

That's confirms what I found with the "export" trucks, when we pull up the axle and spring arrangments in Mack parts it really dont tell us what rating the springs are. There are 5 different steer axle springs for the CXN, 12K standard with or without grease fittings, 12K heavyduty with or without grease fittings (as per Mack Service Bulletin I found)and then one part # for the 14K spring (does not say with grease fittings) Thanks for the VIN. Also your truck has an active recall for the fuel injector lines, Recall # SC324, you might already have the new injector lines installed due to another repair, like replacing exhaust manifold gaskets.

There are several retrofit DPF's for trucks out there. http://cumminsemissionsolutions.com/retrofit.html for one, Mack even endorses one on their website, Huss Retrofit is recommened by Mack but they cant even make their website stay up! http://www.motortrend.com/features/newswire/41570/index.html. I think $1500 to 2500 wont touch a total install. FJH, have you went to the Mack SCR school yet? We had guys there this week in Chicago and next week in Atlanta. I'am setting out on this SCR stuff as my brain is full!

I would like to see someone get one installed for $1200 to $2500!

Just the last 6 would be great. I thing I found some VIN's. Looks like back in 2005 Mack exported 150 CXN's to Venezuela, They had (I think) 14k steer axles and Mack 18 speed trannys. Like to look up your VIN to compare, Thanks!

This is for a CD/radio but I think the controls are the same, hope it helps.

We are looking for the VIN of a CXN613 with a 14,000 # steer axle springs. We are changing them over to the heavier springs due to being converted to a RV/motorhome. Thanks for any help!

Look under the center top of the dash where your CB would set, a triangle shape cover with 3 screws. should be a small piece of paper with fuse location on the cover, if not I can post the fuse chart location.

Here is the diagram, If you can figure it out your better than us. Starting with the CXP, CTP, and all Macks with the MP engine, they switched over to the Volvo style wiring diagrams and they are horrible it read. The older diagrams my 8 year old could read and understand.

Replace the big solinoid that is right in front of the fuse panel. This powers up everything that is turned on with the key switch. They carry alot of amps/heat so after a few years they start kicking out. They naturally get hot enough that you cant hold your hand on for to long (this is normal). We replace 1 or 2 a week. They made a couple different styles by many different vendors. Some of the first were black plastic, most now are round metal. Be sure to get one from a Mack dealer, we have some trucks come in with Ford starter solonoids on them, they dont last long.

I guess it was the first ETECH's , later thay came out with a download and we were told to remove the resistor. SL210013 Pub Type: Letter Group Code: 210 Number: SL210013 Former Number: Date: 10/23/1998 Model: E-TECH™ ENGINE Title: ENGINE MISFIRE — E-TECH™ ENGINE Engine Misfire — E-Tech™ Engine In certain vehicle applications and operating environments, a temporary engine misfire with accompanying white smoke may be experienced on some E-Tech™ engines. This condition will generally be noticed when the engine is idling with the coolant temperature in the normal operating range, and little or no cooling air flow across the charge air cooler. It may also be noticed when a loaded vehicle accelerates after a momentary stop (such as stopping for a traffic signal, toll booth, etc.). To eliminate this condition, an engine ECU service data file has been developed by Mack Trucks, Inc. To receive the appropriate data file, a request must be made to the District Service Manager serving your location. Other means of correcting this misfire condition, such as installing a resistor, must not be used. Additionally, any trucks which have had a resistor installed, must have the resistor removed, and the engine ECU must be reprogrammed with the proper service data file. To summarize, the following procedures must be used to correct an engine misfire as described above: Contact your DSM and request to have the engine ECU data file activated. Use MackNet to download the engine ECU service data file from the MACK Mainframe. Program the engine ECU with the new service data file. Upload the verification file to the MACK Mainframe. Remove the resistor if one had been previously installed.
