Int'l Gets a Bad Rap...Why?

Sounds like the common consensus is "don't get a MaxxForce engine".

 

Keep a close eye on the fuel pump. Educate yourself. Even the new fuel pumps are blowing apart. It should be a regular maintenance item and rebuilt every 300,000 to 400,000 miles.

 

Maxxforce is not a Detroit. Not even in the same universe.

 

Hello, new to the site. I see alot of you have road trucks on here. Im trying to get more info on the new X15 cummins engine then anything but all info would be greatly appreciated! i
Im thinking about buying a new international HX 520 dump truck looking to get the new X15 cummins engine and since theyve been out almost a year now if people have some miles on them and if theres any problems with them. Im going to go with the 485 performance series engine at least maybe bigger if i need to. And it will be coupled to either the 4500 rds Allison or possibly the 4700 ofs Allison if they are stronger and more durable?

 

Well, there has not been much feedback yet on these motors. One thing I would do, is make some calls to Cummins and find out about the fuel pump on that motor. The ISX CM-2250 and CM-2350 all have very real engine ending problems with these pumps. I would want to know if they have made real changes or if it is the same pump found on the older motors. If it is, they will need to be rebuilt every 300,000 to 400,000 miles. I would also want to know the signs of a fuel pump eating itself alive, there are some fueling codes that will be thrown and I believe a warning light just prior to it destroying the motor. If caught in time, the motor is salvageable. But like I said, I would call an actual Cummins shop and see if they have done anything to address this well known issue. Hopefully they have at least found a way to keep the metal pieces of the exploding fuel pump contained so that it does not enter the motor.

 

You got it right

 

Fuel pump got you good info, I only have about 210,000 an it, thanks for the heads up

 

They make a rebuild kit for it. You should have the two cylinder pump on yours, I believe the kit runs around $350 Oh, you will throw fueling codes when it starts to blow apart, pay attention and if you ever see a fueling code pop up, shut the motor down IMMEDIATELY! Do not drive it, call a wrecker and get it to a shop. I would call Cummins and ask them what codes to look for, they should know. If not, find someone that does. When the pump goes and is not caught, your motor follows right along, in most cases they cannot be salvaged.

 

The older International (9400 and 9900) were great trucks. Solid power plants (International and Cummins were partners for a reason), excellent cab and sleeper design, solid builds. Excellent workhorse trucks with a decent amount of comfort.

With the advent of the ProStar series and the Maxxforce, things went downhill in a hurry! Engine was junk, no question. Too many design flaws on the interior to list. And the build quality? Garbage!

Want an International? Get yourself an older 9400 or 9900, depending on hood preference. Eagle package upgrade of you can find one in decent shape.

 

I drove the older ones, but I like my prostar over them, the prostar runs good and turn on a dime almost like my Volvo 670 I had
