The ECM has a self learning capabilities and it might be possible the ECM reprogrammed itself when the values of a disconnected pressure sensor when you turned it on. It self calibrates, I'm not saying thats the case but It might be something to look into. There is service bulletin PV776-89064958 for replacing the sensor. While your sensor may not need to be replaced, you may have to take it to someone that can reset the parameters. Here is a paragraph from the service bulletin. Technically it shouldnt reset itself but anything can happen when it comes to hardware/software. "Due to the electronic control module’s self-learning capabilities, it is necessary to reset the learned data parameters after replacing or servicing certain components. This allows the electronic control module to calibrate itself to the new component. Using Tech Tool, perform Calibrations 2549-07- 03-01 Function Monitoring Parameters, reset the parameter related to the component replaced or serviced."

I'd love to see that thing tearing up an oval track like in the beginning of Smokey and the Bandit 2. That is a really sweet looking rig! -

Your mother and I didn't raise you to act like this, you learned it somewhere else. Mack has forever had issues with stick-slip Phenomenon in the clutch cables. They call it "Phenomenon" because science hasn't been able to cure it or properly/measure/define/predict it. Mack never cure it either. Your nylon surfaces in the clutch cable rub till they become mated. Once they true-up the stick slip starts to kick in. We have it in our wet brake systems, I have to put an additive in to relieve stick slip. Every time you slide your trailer tandem you experience stick-slip. It takes a lot of power to get the slide action to start, but once you break loose it takes less power to move. Install a new cable if it's bugging you. If it's an air clutch system make sure you have the proper updates to keep the weather out of the assist. https://en.wikipedia.org/wiki/Stick-slip_phenomenon Good luck!

Does it have air assist clutch? Those air cylinders go bad & make them hard to press. If so it’s best to just do away with it & put regular cable on. Did this to my CHU.

I have been to the Autocar plant in Birmingham, Al. for a tour and saw this truck up front. I sat behind the wheel and this is an awesome truck! The design is well planned out, the interior is really beautiful and the outside is rugged. If this model succeeds I can see them maybe offering this as a class 8 tractor. What a wonderful idea of an American owned and built truck.

I fail to see how a Mack trans can affect the clutch pedal, given that clutches are outside the trans, and you can put whatever brand clutch you want with whatever trans you want. I realize you hate Mack transmissions, but this one stumps me and just smells of irrational prejudice. Replacing trans because the clutch pedal is hard to press is about the dumbest thing I've heard. Rilex, give more info. Is the clutch properly adjusted? Is the clutch brake in good working order? Is the throw out bearing grease?

2016 cxu 613 mp8 auto lightning bolt
upsman replied to Catman's topic in Modern Mack Truck General Discussion
Engine symbol light only for emissions issues. Lightning bolt means electronic malfunction. -
I reckon it will use centrifical force to separate the water etc from the fuel Fuel floats on water so as it spins the water flow over the side and the fuel will run down Just a guess Like a centrifical oil filter Just clean and reassemble, last for ever and the engine oil stays spotless Paul

kscarbel2 He was a Mack man from the best times and has a vast knowledge of parts, suppliers and people. He is THE person for that info. The Autocar new truck post and most all the trucking news is his from his work association. Paul

A day late and been around before but worth repeating......

NO NO NO the cable will create some drag as it gets worn but if you have a Mack trans your gonna get stiff clutch, done mine twice, works great for couple weeks and goes right back to same crap, all the fuller trans trucks don't seem to have that problem, one more good reason to run a fuller trans.

Project Nightingale: Google accesses data of millions of US patients…..without permission BBC / November 12, 2019 Google has gained access to a huge trove of US patient data - without the need to notify those patients - thanks to a deal with a major health firm. The scheme, dubbed Project Nightingale, was agreed with Ascension, which hopes to develop artificial intelligence tools for doctors. Google can access health records, names and addresses without telling patients, according to the Wall Street Journal, which first reported the news. Google said it was "standard practice". [?????] Among the data the tech giant reportedly has access to under the deal are lab results, diagnoses, records of hospitalisation and dates of birth. Neither doctors nor patients need to be told that Google can see this information. The Wall Street Journal reports that data access began last year and was broadened over the summer. Ascension, which runs 2,600 hospitals, said the deal would help it to "optimise" patient care and would include the development of artificial intelligence (AI) tools to support doctors. The company also said it would begin using Google's cloud data storage service and business applications known as G Suite. Privacy concerns However, Project Nightingale has already attracted criticism from those who argue that it takes away patients' control of their own data. "There's a massive issue that these public-private partnerships are all done under private contracts, so it's quite difficult to get some transparency," said Prof Jane Kaye at the University of Oxford. "Google is saying they don't link it to their other data but what they're doing all the time is refining their algorithms, refining what they do and giving them[selves] market advantage." In the UK, Google's AI-focused subsidiary DeepMind was found to have broken the law when it failed to explain properly to patients how their data would be used in the development of a kidney disease app. -
Did it snow yet where you live? We got hit at our factory in Indiana, but not like this. Autocar fan David Monteith shared this photo of him driving his Autocar snow plow a few years back, just outside Philadelphia. #AutocarDC #AlwaysUp #SnowDay #WorkDay Always Up - Autocar Trucks .

I put a new seat in my 99 ch the seat was legacy made by Seats Inc I am 5'11 and was pretty comfortable

Replace your clutch cable, they fray internally and generate resistance.

If you're the owner operator, it's no big deal. Just don't let anyone else drive it. Great to hear you have 40,000 hours on yours! My 95 e7-350 has 19,550+; curious how many hours I'll get out of it til it gets rebuilt. Runs like a champ!

Parking vintage semi at your house.
JoeH replied to 68-f-model's topic in Antique and Classic Mack Trucks General Discussion
Careful on those 2x's that the garage door tracks hang from, they should have a diagonal brace to hold them from swaying. If they away, it'll pull the wheels out of the doors and drop it on your head. I'd have run the 2x's past the collar tie and put diagonals in above the collar tie to maintain headroom. -
You wired right from the head to a switch bypassing the relays and clutch switch and dash switch.? I did that for a test once ,but didnt leave it that way. The way you have it you can engage the jake with the throttle depressed and make a lot of smoke.

I know the owner of that truck he must be really proud of it! If it was warmer out I would take a ride up to see why he wants so much for it I think there is one like that setting in the weeds up on rt.6 and there is one a little newer setting in the weeds up on rt.11 going to Hartford.pa.
