Ok thanks

I really dont know. The guy said exact same thing but i know how that goes lol

Sorry the trans shop said the transmissions are the same thing just want to be sure. Exchange is 4k one year warranty

I need a transmission rebuild for a t2180b 13 speed problem is everyone around me is pretty booked one place said that they have a t318lr for exchange can anyone here tell me for sure it would work? My truck is a 13 speed but i think if it had tbe different shifter it could be the 18 speed please correct me if wrong. Losing jobs like crazy lol. Thanks fuys

Im going to repair the harness for now and see what it does. I know repairs on the harness isn't the "right" way but it seems to be my only option with no available stock for right now. I come across some used ones at vanderhags that say will need repaired in a few places for 700 dollars i think ill just repair this one one for 50 and see if it will run. The used ones are probably no better than what i got. Ill post back with our findings. I appreciate your help so far..

Anyone need a really clean pinnacle with wet kit that dosen't run lol .

Right i figured it would have some codes. It did have an inactive #1 injector code but none were active while it was running like crap. Im still thinking cups but going to have to do something with the harness. I know on 1 and 3 there were bare wires together. The engine kinda looks like it could have been into before just because of paint stick markings on the injector rockers and so on like they marked them when they set them but its hard to say. 49k miles is nothing but i know guys for a different oil field company that were doing cups every 20 k they say. 49k miles with a bunch of idle time whike on the job cant remember the hours right now but its more than 49k miles.. just hard to say i know they had replaced parts and was really hoping to not see any signs of the valve cover being off before.

Part number should be 21401715

I finally got around to pulling the valve cover on this thing. Found a whole bunch if bare wires on the injector harness seems odd that its so brittle already but anyway of course mack nor volvo show to have it in stock maybe one dealer in new york has one waiting to hear back. Not sure if this would be the problem but i know it cant ride like it is. And i guess its the whole damn harness anyone got one laying around or know where to source one at? 2008 mack chu mp8 last 8 8n003286

Ok i will do that when i can source a banjo fitting. I appreciate the reply. I have a feeling its cups too but dont want to go through all that and it not do anything to fix the problem. If anyone knows about the upgraded cups vs oem injectors that would be great

Anyine got any ideas or has anyone ever experienced a similar issue i know that it could be anything. I think that bad cups sometimes causes problems in the hand plunger on the filter head. Thats kinda where im at since it looks like everything was replaced up to the cups. I cant really see too much areated fuel in the tanks. Whats the best way to condemn the cups? If it is the cups can you replace with the upgraded cups without replacing the injectors or do u have to go back oem

Im coming to you guys once again for help with this mack. First this truck was just purchased at an auction started and ran great there. it was an oilfield companies truck it has 49, 609 verified miles so obviously it has sat the majority of its life. Had it towed home got in it and maybe drove it 45 miles to have new rubber installed then it starts missing and wanted to die got it back home barely changed fuel filters then started noticing that it had a new looking filter head and a new looking fuel pump so i know mp8 engines had injection cup problems and thats is what im thinking. There are no codes and i changed the over flow valve pressurized the tank to help bleed out fuel system did not see any leaks etc. Truck was a long start and ran at idle fairly decent for 30 min. Then the miss returns and barely had enough power to back up 10 feet to get back in the shop. Just curious what you guys may think and if injection cups is having the truck sit for a long period could be what caused it with that low mileage or just that its dumb luck lol. I appreciate any help you guys could throw at me. Thanks..

Thank you Mackpro that helps a bunch!

I'm just trying to get an ideal on what the labor hours are on a head gasket replacement would be not counting the machine shop etc. Thanks for the help.

Yes I have a feeling the officer will be on the lookout for the truck and it probably would not go in our favor. I will be doing what Joey mack has done. Thanks for all the input.

It's the new style cluster

If it would help anyone the last 6 of the vin is 140084. I asked mack today when I called about the cluster and they couldn't tell me the wiring or what pressure switch did what they say there system just says pressure switch.

That was my thought also. I don't know if it changed or not but just hoping I can fix one up pretty easy. Really dont want to run into the same cop and not have one working I guess.

I've got an 01 ch613 (dump truck now) the D.O.T just shut down the truck today for the low air pressure buzzer was inoperative the light works fine and the buzzer will off and on if you slap the top of the dash. The buzzer is in the instrument cluster and not replaceable mack says. The cluster is about 800 but 5 weeks out here in our area. I'm looking to see if someone can tell me what wires at the back of the cluster I could tie into to install a different buzzer or where the buzzer gets its signal from. Just need to get the truck back in operation the odds of running into the same cop here are very good. I appreciate any help.

I will check it in the morning when I get over to the truck. I dont think it makes oil but I'll have to verify that with the driver. I looked at the wiring for the coolant level sensor at the sensor and did not see coolant in the connector. I will look at the exam connections. Thinking about it now I remember trying to start it a few days ago and it will act like its gonna start for a second it did this a couple of times but would not go ahead and run. Oil psi while cranking is reading low runs at 25 hot at idle 50 while driving. It's hard to see exactly what it is while turning the engine over with the starter. I will check it out in morning and report back thanks for the help so far

On the fuel pump it does not have a filter. Just the small gear pump with the plastic gear I know that those have been known to let the plastic gear spin on the shaft and not give proper fuel pressure but seems like u would have running issues.

Ok I will see if I can get blink codes out of it today. I have a laptop with jpro but its not working at the moment hard drive crashed. Anyway I can pump the hand primer till your blue in the face with really no change. Just changed the coolant surge tank from the plastic 2 piece to the aluminum one from mack it came with a new sensor was hoping that would do it but it had no affect. Starter was replaced less than 2 months ago but I will check connections and ground. Batteries are a year old and did clean the cables and nothing changed.

First the truck started out as not starting while the engine was at operating temperature now it doesn't want to start when cold. A little starting fluid will start it hot or cold. After the first start it doesn't matter if it runs all day or 15 minutes it will not restart on its own without spray. Trucks runs normal after it starts. This is the ac etech 360 hp engine or whatever the right term is for it. There is fuel in the davco filter check valve is holding. Replaced the return fitting with the check in it on passenger side of engine. Fuel pump possibly? Just need some places too look. Thanks for the help Quote

I see what you are saying. So change cam, heads, unit pumps and injectors ok. Has anyone ever changed one of these engines over like this anyone that has could you share your experience with me.. did it work out ok after was it a waste of time etc.. thanks guys
