By mimscorpApril 21, in Engine and Transmission. I've had numerous problems with the Micro switch on the accelerator linkage. In my opinion Mack didn't use a very suitable switch for its application.
I straightened this out with a much higher quality switch. Now, having got the switching issue under control I am not at all satisfied with the hold back property of this system. Consequently, my question is this. Seeing how the brake is definately workiing is there some problem that can make it have a reduced effect or is this "As good as it gets" with this type brake. If it is possible to be operating but not well what can I do? I'm, for the most part, very satisfied with this unit and would like to restore it to A-1 condition.
The problem is that it has a double frame that is rusting between the members and making them tweak out of shape. What can be done short of dissassembly? A engine brake on a E 6 engine is not what many people exspect. They work better if you open both doors wide open with windows rolled up when you want to slow down. But they are great to shift with on a up hill shift. On the engine brake keep in mind you only have cu.How To: Valve Lash Adjustment (English)
The valve adjustment has a huge effect on the effectiveness of the Dynatard. Keep a good tight. As for the frame little can be done short of replacing the rails. That will eliminate the problem. It is possible that only one head is working.
The silinoid on the rocker shaft does go bad. Take valve covers off and flip switch and see if both go up and down. They did make a Jacobs setup for a 4 valve E6 I have seen only 1 never ran it to see if it was better or not. But it would have to be an improvement.
Every truck that I ran with a Dynatard or a Jake was different. Not one acted exactly the same. Some were weak Dynatards or others really strong just like the Jake setups some were good some weak.

Find Trucking Jobs. Valve adjustment procedure question Discussion in ' Mack Forum ' started by brianApr 18, Apr 18, 1. Does anyone have the procedure and specifications for setting valve lash on a E in a CX Vision? I have done this on Cats and Cummins but never a Mack. Yes, let employers and TruckersReport text me with new opportunities, job alerts and other career information to the number I provided.
There is no charge for this service, but standard message and data rates may apply. Apr 18, 2. I do not have my book here tonight but intakes 16, exhaust I believe the E7's have timing marks on the flywheel but it takes two and I was often alone and use companion cylinder method.
Write done the firing order. Then under that write down 6 2 4 1 5 3. Rock the valves on 1 exhaust closing and intake opening and adjust the valves on 6, draw a line through 6. Then rock 5 and adjust 2, etc. You can start anywhere as long as you keep up with it. If no one else answers and you want by the book let me know but it will be tomorrow. BoxCarKiddApr 18, Apr 18, 3. Apr 19, 4. No problem only 7 and a half pages.
The first 4 tell you there is a pointer in the center of the hole, at the bottom of the flywheel housing, after you remove the cover. Tool JA is used in the flywheel housing hole at the right rear of the oil pan to rotate the engine.
If you cannot read them there are instructions on here to remark them if you have a typical flywheel. If you have a non-typical flywheel it should be replaced. Then use the marks and adjust the valves the same as I explained in the companion cylinder method. BoxCarKiddApr 19, Apr 25, 5.

The history of the engine is steeped in technology, tradition and good old American gumption one would expect from Mack. The e7 mack engine was first conceptualized in by the Mack Corporation engineers and introduced in The Mack E7 Engine replaced the longstanding Mack e6 model and was produced for over 20 years. The same year Mack also introduced the CH Series for on-highway heavy duty applications.
The engine is 6 cylinder, heavy duty rated and in use both for on-highway and off highway industrial applications.Decorative melamine panels
Mack engines are known for their per foot pound of torque output. Comparing a hp CAT to a hp Mack is like comparing cats to dogs. This allows power down low where you need it during pulling situations. It is not unlikely to have a Mack Engine put 1, miles hauling full loads and not need a major overhaul. Mack E7 engines are found in mining, oil and gas, agriculture, construction, pumps and compressors and power generation.
Typical horsepower rating for the mack e7 is between hp.
At the lowest rating of hp the mack e7 engine will put out foot pounds of torque. Consequently, at the highest hp rating a Mack e7 engine will put out was hp at an impressive 1, foot pounds of torque. The vast majority of mack e7 engines still on the road are later models which are all water cooled. The original design up Mack E-Tech Crankshaftuntilfeatured a turbocharged air mounted cooling system. After Mack engineers developed their patented Econovance variable injection timing system which increased fuel efficiency greatly and cut emissions.
Since more redesigns have been implemented to meet EPA regulations. The Econovance system was used exclusively on the E7 engine but not adopted by other production lines at Mack. The higher pressure injection system improved fuel economy and combustion productivity all while optimizing proper oil viscosity and reducing engine emissions.
Due to the increased air flow a byproduct is less pressure on the injectors.

Customers are happy to find that injector failure is quite uncommon with Mack E7 models. The Mack E7 Engine ended up being one the most popular industrial diesel engines of all time. Both large scale and small scale operations flocked to the Mack E7 Engine because of its reliability and fuel efficiency. Up until Mack ended up producing 16 different varieties of the E7.
Mack E-Tech engines are still being produced and are still known for their outstanding horsepower to weight ratio. The fuel injection system uses an upgrade to the Econovance technology of the E7 called the Mack V-Mac III electronic fuel control system which utilized electronic unit pumps. The E Tech engine also uses high swirl combustion for increased fuel efficiency and emissions production.
Like the E7 the E-Tech features dual flow paint on oil lubrication system with a 34 quart capacity. The E-Tech has upgraded high rated steel crest articulated pistons and both wet and dry liners for long standing resilience.

It has a long history of not running right and smoking like crazy white fuel. The owner asked me to pull injectors and have them tested they tested fine. As I was pulling the injectors I noticed that valve lash seemed very loose, when checking putting the flywheel on valve adjustment marks the clearance is right.
I have no experience with mack engines but this seems very strange.Please Log in to join the conversation. Post: P.Lg l34c reset

Gday guys, I've been playing with the Dynatard on the Mack- I read a while ago that the connection on the back of the injector pump should be connected to the dynatard lead that runs across the rocker cover- This means that the fuel pressure will shut the dynatard off at idle or under acceleration apparently.
At the moment, my dynatard is either On. Not a good look when you foot it again with the dynatard on!!! This is the back of the injector pump, with wire connected. Re: mack Dynatard question RicHard Gudday M8 RE: the top pic the screw of the end of the fuel pump is the beast u need to play with it can b a minute adjustment I'd suggest U get the truck upto normall operatin temp 1st on the screw there B a lok nut n back er off then adjust the screw in Pure guess here rev motor 2 C if dynaretard iz working That was my guess!
But I was reluctant to get stuck into playing with it without some much needed forum wisdom Powered by Kunena Forum. Page: 1. This is the back of the injector pump, with wire connected- BUT when we connected this wire up, now the dynatard seems not to work at all under deceleration, until the engine hits idle again, then it comes on, and stays on when you try to accelerate!!!
Needless to say we have disconnected it again Obviously we are doing something wrong- Is there an adjustment in the injector pump? Or some way of telling the 'tard when to be on or off?
