Thanks and you're welcome. I hope it to be useful to all. I personally don't think this particular post is valid enough to be a sticky. But, if the board wants, I can combine all of the alternator and bracket info into one single post and then (they) make that a sticky. I have published all...

On a 250 engine, the top bracket is just a brace or strut. Exactly the same piece is used. On an 8.3 engine, this is just flipped over, as the alternator is clocked 180 degrees from the 250 position, so, on an 8.3, the top mount changes and the bottom mount is just a brace to the single...

It is a sound engine. May glaze over if you start pouring WMO down its throat though. The DT-E series is electronically controlled, so you should just need to add the correct pedal and sensor, and you're off to the races with real power and no issues or leaks. Guys turn this engine up to...

I was in a mess like this with my fuel gauge. Big surprise. I swapped gauge, NG. Put original back. Swapped sender, still NG. I then connected the new gauge and new sender together on the bench and supplied 24v to it. It worked perfectly. I swapped both into the truck, and the system...

We have a perfect running DT466E and MaxxForce 7 that we are getting ready to discard at my work. Sorry, we are not throwing away the ISX or ISB's yet...

Any pitting on the top of a piston is either too much heat or mechanical indentations from a foreign object bouncing around in the combustion chamber during running. Engines that exhibit pre-ignition/detonation will typically show this. I have never seen a ring gap close unless it is loaded...

Thanks for the info.

If you want it by the book, then any 15w40 oil with an API rating of CH4/SG in the starburst symbol.

None of the M939/A1/A2 were originally equipped with ABS. They all should have been MWO's to have ABS added, unless liquidated before the MWO went active. http://www.roscommonequipmentcenter.com/MWO%209-2320-272-35-1.pdf Battery may and should absorb any spikes, but an oscilloscope would...

They now have park and neutral rev limiters to prevent slam shift on the auto transmissions. With electronic throttle valve now, this is easy to do without giving the customer the old style rev limiter feeling of cutting out spark. I have seen rods through oil pans and blocks also. Usually...

Interesting, thanks. We could not find such information when working on an ISX and was told Cummins does not publish such info. What is the source of this info (what is a QSOL)?

Disagree. Going without it may cause voltage spikes into your system, and could fail electronics which are not protected against such, such as the ABS module (proven to fail) or the voltage regulator in the alternator. They added it for a reason. You'd have to put a scope on it to confirm...

0, once, and fine, respectively. I'm not sure what any of that has to do with engine longevity, but mine is still running great through all of that regardless. I said I can help load your pistons whenever you are ready to do so. You are not at that point yet. I don't have time to sit around...

Who has a 39 page thread of their engine not running right, and being fully apart....twice?

It is needed because when the horn solenoid releases/closes, it generates a big spike that would otherwise go through the system, much like an ignition coil (they discharge their high voltage when power is removed and the mag field collapses). If your horn switch tests OK, then it is probably...

Your wife didn't do anything wrong. Way cool she will get in and handle it. An A2 doesn't need the fuel cut reset. The fuel cut solenoid is problematic though on these. It will go to stop mode even after extended cranking as it heats up and battery voltage drops. I say add 10 gallons of...

Thanks for the support. A rod typically comes apart at TDC of piston travel, while attempting to reverse and pull the piston weight back down from the upstroke. I can't see how engine being loaded vs not would make a difference. I have always heard people scared to rev an engine on no load vs...

The bevel info was posted earlier in this thread for you.

I was unable to thank this post twice, even though I tried. Mostly in part that it will run 2800r's just fine, and probably run the best it ever has after that. Then, when we finally drive down to the Findlay show, he'll go more than 49mph, maybe we can actually tool along at 55mph. I'm...
