Anybody running an ISX that would like to comment on it? I'm looking at a truck that has an ISX 435 hp in it and would like some information on your experience with it and your thoughts.

Rev, if I remember right you have an ISX 600? (I think) care to critique? even though you are a HHG man :lol:

 

We've got one in a dump truck where I work, and the other trucks in the fleet with Cat C12's and C13's with roughly the same HP will pass it like it's standing still.

 

That's because CAT seems to underrate their engines.

 

I am very interested to hear the comments on the ISX also, I have heard they have lots of trouble with the EGR valves and wonder if this is true since I would like to trade my 02' KW in for an 06' sometime within the next 6months to a year and would consider a cummins if they don't have to many problems. A driver I was considering hireing said he'd been driving an 07' cat and had 180 codes already and has had to stop twice for an hour or better to let the PF burn clean.

 

Yes the EGR valves are a problem. I think not idling would definitely help out with that though. Underhood temps skyrocket idling in summer.

 

2006 ISX 475 now at 550 with 300,000 miles. Been a good engine with minimal trouble. Knowing what I know about Cats offered at the same time, I'd spec the same engine again in a heartbeat.

 

I had an 07 International with a 565 ISX. The thing belched black soot like it was going out of style, and the mileage went from 6.2 to 4.75 before we turned it back in. Cummins said it was some kind of computer problem but they didn't know how to fix it :shock: . The wash rack was always a waste of money.

 

Wow, good comments thanks guys. What about the the average life of the ISX before rebuild?

 

I do recall my 475 kitty yanking Bandits Cousin through the hills of eastern oklahoma and on the flat ground...we were only 1k lbs. apart weight wise. My motor has about 800k on it without being touched, and his has less than 200k on it. His is a 525 isx with 3.70 rears and a 13 speed, and I have 3.55's with a 13 and tall 24.5's. Something tells me his extra 50 horsies and better gearing for pulling hills should have made the outcome different. 8)

 

This might not be a bad deal here.

2004 Int. 9400, 51" Low roof, ISX 435, EF 10 sp OD, Fontaine A/S, 3.73 ratio, 214" wb, 237,000 mi.

All maintenance records, and oil analysis. I can get a recent one done if I want to. It's coming off an Ideal Lease.

40 K or M whatever you prefer. :lol:

Anything comparable on truck paper was 47 to 49.

Thoughts?
