The kit was to help with Jake brake issues on engines with high miles and low oil pressure, if your engine brake works good when hot this migh not help.

Mack alway told us , dont change the cam bearings unless its grooved up bad enough you hang your finger nail on the #2 and #5 cam bearing. We rarely ever put cam bearings in ETECH style engines. This was back around 2000 when we were doing 3-4 cam jobs a week under warranty.

On a disc its probably Volvo or mack only. We are online with Mack

98 ch613 fault code 35
Mackpro replied to stinkypete's topic in Electrical, Electronics and Lighting
In 1998 was the year the ETECH first started to appear. You could get the E-7 VMAC or ETECH engine. Is this an ETECH? Or a injection pump VMAC engine? -
Its controled through the engine ECM. The ECM looks at coolant temp, intake air manifold temp and A/C head pressure ( and can be set up to turn on when engine brake is turned on). Any of these things can turn on the fan. 12 volts comes from the fuse panel and goes through the solenoid to the engine ECM. The engine ECM grounds the solenoid wire to turn on the fan when it sees the correct input from any of the above sensors..
-
Yes, its the exact same. Even the VCADS/ PTT troubleshooting software program is the same for Mack and Volvo. Your pass word lets you into only what your allowed view.

I have seen some of the same exact parts have different part#'s for Mack or Volvo. It might be something as simple a the box it comes in. We have called Mack Parts specs before for a part that Mack was out of and they could find the same part over on the Volvo side, just in a Volvo box. We as a Mack Dealer can't look up Volvo parts on Impact, if we were a dual dealer we could.

As long as Mack uses Bendix instead of meritor/wabco, Im happy. I would not put anything Meritor/Wabco on my truck or anyone i know's truck.

Thats good news!

Check this bulletin , it tell how to check the flywheel. 3-4 code.pdf
-
We had a customer that built up an ETECH engine from spare parts and put a VMAC 1992-98 flywheel in it. No knotched teeth on the flywheel for the sensor to read, had the the 3-2 code.
-
As far as the EUP itself, I dont think there is a + and -. It just makes a simple circuit and activates a electro-magnet in the EUP. But all the harnesses are laid out that way. I one time reversed the wires on a EUPto see what would happen and it still fired with no miss. But I could be wrong. Lol

Mack the king of recalls! at least it gives me something to do other than injector cups and DEF pumps!
-
flywheel sensor (RPM/TDC sensor) bad or not reading correctly. It should start with out sensor plugged in but usually have to crank on it for 10 seconds as its using the cam shaft sensor to calcuate timing.
-
In 2017 we will hopefully see the common rail MP engine here in the states. Being tested in Europe as we speak. Hopefully it will mean the end of the cup and broken injector issues.

All new engine ECMs are blank. ( pretty much) . You can plug it in out of the box and truck will start and you can drive it but it will be weak. The part # of the engine ECM has nothing to do with its HP rating, your new ECM could be used in a 275 to a 460 HP, Its all in the dealer programing it with the info/HP of your engine from Macks mainframe computer system. On that style ECM , a tiny dent on the cover can short one out. Looking at my AI engine HP chart. The 350 and 400 HP is exact same engine except the programing is different. when you go up to the 427 or 460 HP the turbo and injectors have to be changed. 427 and 460 use the same injectors but the 460 has a bigger/different turbo than the 427. If you were going to pay that kinda money might as well go all the way to the 460 HP.
-
There are other things that need to be changed other than the programming to bump the HP. My chart is at work on Part differences between HP levels on the AI engine. Chances are you need a turbo or injectors or both to get to 427 if you did keep the 427 engine ECU on there. As a rule of thumb 350 and 400 HP turbos and injectors are the same. 427 and 460 use different ones. There is not much stored on the engine ECU , besides the HP level, there is fan type (air or viscus or electric viscus) , fan temp engagement, A/C (yes-no), engine brake type and a few other choices of things. You could use the 427 ECM as long as it was AI engine and the above choices were set correctly. But to say your gonna get 427 HP, I doubt it with out injector/turbo swap.

Finally got that Bulletin to attach , it might help in the future. snm 13- 022 kev2 spn5394 fmi17 diagnostic.pdf

Good news. Sometimes the codes wont go inactive after replacing the NOX sensors , we have to clear the codes and test drive or do acouple of regular regens.
-
Blow-by filter on timing cover clogged. removed top cover and wash out wire mesh screen. If it has milky sludge in the filter you might have leaking liners.
-
Your local dealer has to apply for you ( I think) . Its called "Trucks Customer Portal". We have never set it up for any one yet.

Is it an ETECH engine? -
Check this out injector harness.pdf
