Has any one out there encountered this problem like I have with the hour meter reseting on the total display and not on the trip side. Is there a way to retrive the real time in the computer or is it gone forever.

All the info is stored in the VECU not in the dash cluster. If you replace the dash cluster the stored info will show up on the new cluster. We do replace alot of dash clusters but none for that reason. I'll search my Mack service bulletins for dash cluster issues.

i asked more than a couple times if this truck had a fresh service on it when i bought it, and was told yes, just serviced.

they replaced both long power steering lines, surely one of the bolts that hold the lines didn't get picked up by accident?

maybe used same drain pan for both jobs, screw got left in pan, and drain plug got dropped, it's a long shot, but possible.....

Your safe on this one, Its a common Mack screw but not used anywhere inside the engine.

trying to upload pix now found a 1/4" x 1" bolt stuck to the oil drain plug magnet

Yes. post a pic. is the bolt complete/not broken? Does it have a flange/made on washer?

if i do this repair myself???

can i reuse fuel lines???

is it unsafe to do so, or is it just a ploy to make you buy fuel lines??????

To save money you could do it your self, it's really not that hard but I have done so many so it seems easy to me. Mack says no-no on the reuse of the fuel lines but this is for liablity reasons (alot of AC engines caught fire due to reused lines). Any time we do one under warranty we use all new everything and follow the newest service bulletins. But when we have one not covered by warranty and the customer is dirt poor, we have just slipped in some new gaskets and reused the fuel lines. If you mark the line with the location and install it back in the same hole most time it wont leak. We do a long test drive to make sure (25mile). The real problem gaskets/studs is #3 and #4. If it has the new style studs on those 2 locations I see no reason to change them all if it was my money.

maybe im just paronoid, not used to running this long without a major repair$$$$$ it seems like my turbo is getting louder????? checked all pipe fittings, every thing is tight and proper, kept an eye on boost pressure around 31 psi when its pulling have seen it spike 36 psi some times. this turbo has about 50,000 miles since it was replaced.

i never heard the turbo in my vision.

maybe something was wrong with it. maybe it was just that quiet?

is it just getting broke in????

do i need to get a smaller muffler so the pipes will drown it out????

would the warrenty transfer with new owner??????

is there some thing i need to keep an eye on???????

From what I have seen , when the turbo makes a "squeal" during high boost it is usually a turbo gasket or the intake manifold gaskets. I know you have been through this before but the smaller the leak the louder the noise. All the exhaust back pressure in the exhaust manifold trying to spin the turbo puts a real strain on the gaskets. Make sure all your turbo nuts and manifold nuts/studs are there. I have already seen the new style/ new fix stud/spacer fail on some Tyson trucks.

truck had complete emmision system replaced 400,000 miles. it has 450,000 now, how often should i clean the screen?

should i replace all coolant each time???? can i reuse 50% of old coolant

it has pink phillp 66 coolant, i had trouble with this in other motors. is it okay to switch to the green stuff????

This is all I could really find on the subject. Mack Service Bulletin Date: 11/04/08

Oil Cooler Coolant Inlet Screen Replacement

(November 2008)

A screen (part No. 387GC32) is incorporated into the Y-shaped hose at the oil cooler inlet on ASET™ AC, AI and AMI engines. This screen is designed to trap debris which may be circulating in the cooling system. Over time, this screen can become plugged with debris, resulting in restricted coolant flow and possible damage to cooling system components and/or the EGR cooler.

Oil Cooler Coolant Inlet Screen

1. Oil Cooler Coolant Inlet Screen (Part No. 387GC32)

Anytime the cooling system is drained for any reason, such as cooling system repair, maintenance or the regular coolant drain intervals, the oil cooler coolant inlet screen must be replaced with a new screen.

I just recently bought a 2007 CTP 713 Mack Granite dump truck. It has on it an ugly exhaust elbow going into the muffler stack. And I'am having trouble getting the correct chrome or stainless exhaust elbow I really need. At the mack dealers when I give them my serial number they can't tell me if the new elbow I'am ordering is just a regular steel elbow or the chrome/stainless elbow that I want to change for. I got a nice looking truck but that s shaped wrap around exhaust elbow ruins the look of it.

When the parts people look up your truck, it will only show the part # of the pipe that came on the truck. Your only hope is to find another CTP with a a chrome pipe and get the VIN# and have the parts guys look that truck up and get the part#. I have a CTP on the lot here and just went out and checked it but it was not chrome. Your dealers parts guy might send in a parts E-service to Mack Specs and see if Mack could tell them the part# if they even make one in chrome.

I just got off the phone with MACK OF NASHVILLE and they corrected the part # 446 TC 25 to Part # 446 GC 25. They just called me back and said they could not sell me one seal but I had to buy 10. They would not split up a case for one. I told them to forget me.

Just my luck again

They had none in stock and had to order 10 to get 1 and didn't want to get stuck with 9 of a slow moving part. WorldWide of Knoxville TN shows 8 in stock give them a call.

Hello everyone, I was on here a couple years ago, but I have since lost my account information.

So my uncle, and my boss, has a 1997ish Mack CH612, with a 9spd RoadRanger. After idling for an amount of time, the computer shuts down the engine, he is looking for a way to remove this shutdown "feature" and he is also looking to find out if there is a way to allow the injector pump to pump more fuel. He says he thinks that it will have to be done in the trucks computer but any advice on it would be appreciated.

Thanks, Ben

A dealer needs to hook up to it and disable the idle shutdown and make sure a parameters are set correctly in computer (tire size, gear ratio, governer setting to MIN/MAX, ect ect). If this was a fleet truck it might have a password for computer entry so the dealer might have to redownload ECM/computer, its very common. I would do this first before messing with the HP, turbo, injectors, ect.

Does the new MP10 have EUP's?? The dealer is trying thier best to get us to buy one in a new truck, but with so many problems with the last one I'd rather not have them. I was a Cummins and Detroit man too long I guess. I have heard rumours the the Volvo Mack line will be available with an ISX down the pike, but they only have MP10s right now..

Adam

The Mack MP engines are ,as FJH said, like everyone elses. Single head, overhead cam, unit injector. No more EUP's like the ETECH style engine. The MP10 is only in the Titan, but at one time you could get it in a Volvo at a reduced HP rating, we have 2 D16 vovlos on the lot now. But please dont go buy a Volvo!

Thank you so much for your replys...However, the problem is not that the fan is not working at all, but that it will not shut off and has a high pitch scream which can drive you crazy by the end of the day!!! What I would like to do is be able to put the fan on a toggle switch. That way, when the fan doesn't need to be on I can shut it off. This is why I was wondering about what the five wires do...any help or suggestions would be greatly appreciated!!!

When the fan goes bad it locks up tight, however they really never totally freewheel like a (air) horton or eaton. Back in 2003 in Mack school thay showed us a video of how it works, it was in German so I dont know what they were saying. It does have fulid (like ATF) inside and magnets that open and close passage ways inside to lock or unlock. I talked to one of the engineers at Mack about installing a fan over-ride switch like the air fan clutches have and he said "cant be done".

Hi John!

If you can 't turn the fan by hand its Seazed!You will need to replace it!The wires control what it does when its working correctly If you can't turn it a little by hand its not working corectly!

I made a Behr fan clutch tester out of an old wiring harness plug and some alligator clips. This put 12v and ground straght to the fan to unlock it, Like FJH said if it's locked up tight and cant be turned by hand without slipping the belts, it bad and you gotta change it.

How have these transmissions been holding up over all? The range syncronizer better than in the 200 series?

The syncro's are better but we still change alot of them. The main problem is the driver/trainning, then Mack had alot of problems with the range shift fork bolt backing out and also the out put/rear yoke bolt getting loose and causing syncro failures. I would say 90% of the time it's not the syncro's fault.

Great, thanks for the help. And if i wanted to have the "step 12b" software put in i can only have that done through a dealer correct?? And what exactly doe the step 12b software do?

Gotta be done at a dealer, The download is free from Mack, you just have to pay labor to install. I would also get them to install the newest/latest softwareor datafile in the EECU(engine computer). The new software and datafiles just have newer info to make the truck run better or clear up some software issues.

It is a 2004, and i cleaned out all the sand and grim from under the pedal and lubricated all rollers and piviot points. I also found that the metal pedistal that the pedal rolls on had a grove in it causing the roller to hang up, so I ground down the grove and smoothed it out. Those things helped, but the pedal is still pretty sensitive, the slightest movement in the pedal makes a big jump in RPM's.

Thanks in advanced for all help or suggestions

Mack went through several vendors that made their throttle pedals. When we would replace a pedal made by one vendor with one made by another vendor the driver would sometimes complaine about this. You can have the "Step 12B" software put in the VECU and the dealer can calibrate the pedal and as mentioned above change the governer setting to "min/max". And also I have found a flat spot on the roller on the pedal and the pedal ramp worn down, just as you have found.

any one know how a e7 350 sounds with dual straight exhaust? i would like to put dual 6" straight exhaust on my tri-axle but im not sure how it would sound. i need to cut my headboard down to make it fit alright and i think im going to have to move my air dryer to sneak a stack out on the drivers side. and does any one know where i can get aluminum fuel tanks for a 92 rd?

I work on and test drive a 2005 CV dump truck with twin 6" straight pipes. It has tip outs a little bit above the roof line. Its not bad when crusing but any time you get on it, you cant hear the radio or cell phone. After about 9 months the owner/driver put mufflers back on.

This is from Mack. I tried to copy and paste the service bulletin but the chart didn't come out right. The finer sliding clutch teeth makes it shift better than the T-200 series but still not as smooth and a half worn out Fuller. SB320003

MAXITORQUE® ES (T300) Lubrication

The MAXITORQUE® ES (T300) Series transmissions use the same lubricant specifications (GO-J PLUS and TO-A) and lubricant change intervals as is used for the current T200 series transmissions. These lubricant specifications and change intervals are outlined in the Maintenance and Lubrication Manual, TS494. For transmission lubricant capacity, refer to the chart under the heading "MAXITORQUE® ES (T300) vs. T200 Gear Ratio Comparisons and General Information".

Charlie I have personaly never done this but!I have heard you can take the knob apart and break off the lock out mechanisum Its plastic I beleive!

All we have ever done is just change the knob but the knob is $$$. So you might be able to mod the knob as FJH said but I dont know how.

hey guys

here in the netherlands my favorit beer is GROLSH and when i am in the states i drink mostly budweiser.

we also have bavaria,heineken,amstel and a lot of belguim beers and local brewerys greetings rene

MACKFOREVER

My buddy who worked in our body shop drank Grosch in a green bottle with a flip top stopper lid. I thought this was the same Beer you were talking about but after doing some research , they are 2 different beers I think.

on our 05 granite.it has ai400 since day one it would pump coolant out of the plastic tank.dealer changed the water pump.we put in new stats and put on the steel coolant tank and it still pumps coolant out the tank.any theories?plus sometimes it displays this code s001-08 m128.our dealer didnt know what that code was.our dealer and us kinda have had problems since they put a clutch in one of our other trucks

That code is for #1 EUP= MID128 SID1 FMI8 usual code for cold start up. You need to remove the Rubber "Y" hose between the oil cooler and steel lower radiator hose and clean the oil cooler inlet screen, could be stopped up?

Not a fan of light beer,I like Michelob or Heineken in that order,also I make my own from kits and it's pretty darn good.

A real mans beer I see. I did buy one of those kit's but my wife made me pour it out before it was done. She thought I might poison myself.

Bud Light for my household...followed closely by Coors Light. The 'heavy' beer I just can't get into.

Miller has a pretty strong foothold in my area and every event such as a beer garden or anything else where there's a beer trailer seems to be Miller products.

A few years ago my cousin married into the family who owned the Miller distributorship and their wedding was allllllllll Miller...family wedding pictures in front of the Miller semi-truck and everything... Me, my brothers and our dates, my dad and my aunt brought Bud and Bud Light to the reception just to be richard heads.

Ahhhh. I forgot about Miller Lite, It's popular here as well. My wife likes Woodchuck and will drink it by the pitcher when we can find it.

what makes you think that combination would not make 460hp and after all that trouble why not the 460p file?

It's all in the combonation of things. A ASET complete block and heads has 16:1 compression where as a CCRS has 17. 4:1 compression. You start mixing up parts and you dont know what you got going on

Being that we have Mack fan's/owner's all over the world that post here, whats your favorite Beer? Mine is just plain ol Bud Lite, most popular around my location is Bud Lite, Bush Lite , Coors Lite and Budwiser. Would like to know what my northern friends drink and every one around the world drinks.
