Then the tear down starts, it is really something to watch. Every component's nuts and bolts are put in individual zip loc bags, labeled and placed on a very tall bakers shelf. That is your motor, no intermingling of parts. And yes, all parts are cleaned.

The assembly, all of the parts needed to do a proper in frame are in a plastic container that comes from the parts room. He has the 871, 2250 and 2350 parts sets. All of the gaskets, the little o rings, everything is in there and used.

The slick lube for the bearings, it is there, I have seen the guys rolling in the bearings, they use it liberally. The pre lube of the motor, I borrowed the pump, it works. And the most important part, the setting of the liners. That is done too, no skipping that step.

Mr Hagg get's in there too, both front covers are removed, front gear train, front main seal, etc. Most shops only remove the top cover to remove the cam(s) unless you specify replacing the front main seal.

The best thing, is that they have done so many of these rebuilds, successfully, that they are quick. Not fast and sloppy, but efficiently quick to disassemble and reassemble. No corners are cut, and when other little things pop up, he is quick to address them, like a component that is soon too fail that needs to be addressed. When he says something is bad, it is, he is not the kind of guy to play games with a man's livelihood and he does not want to see you back with issues or broke down on the side of the road. I have heard these conversations and seen the parts. If he says it's bad, it is bad. He has no time for games, shop is way to busy for that nonsense.

When you pull up to the shop, it is nothing to see a half a dozen or more crates sitting in one of the bays or in the lot, those are in frame kits and heads, and they are stacked like cord wood on some days. I believe he is the number one or two ISX in frame shop in the country, and #1 in Georgia. That is one busy little shop.

Mr Hagg has a helluva a system down, he and Rawze worked together in the beginning to do these motors properly, both men have years of knowledge and experience, and they went about ensuring that when an ISX is rebuilt, it is rebuilt to a higher standard than even Cummins adheres too. These two men put their heads together to find a better way, and boy has Mr Hagg run with it and has it down to a science. I would trust no other shop to do an in frame on my motor.

There is a back story here too... Rawze, when he fired up Rawze.com, started hearing the horror stories of shops skipping crucial steps when rebuilding these ISX motors. I was one of those victims. He set out to find a local shop in his area that would work with him and rebuild these ISX motors to a higher standard that he could endorse and say this is the shop you need to take your truck too. That is when he met Mr Hagg... Rawze had the customers, he just needed somewhere to send them. Mr Hagg grabbed this bull by the horns and ran with it. and don't get me wrong here, Mr Hagg knows how to rebuild an ISX, Rawze's involvement was to ensure the steps were being followed so that these motors would not require a second in frame a year or two down the road. This was a good marriage in my book, both men are passionate about doing the job properly, or don't do it at all. I am damn proud to have met both men. They are both responsible for keeping many a man up and running and in business that would have failed due to mechanical issues. I am one of those guys.

I appericate you taking the time to give me more confidences in the decision I have made. now is time to get all my ducks in a row to insure the I have it all worked out on my end . piss poor preparation=piss poor performance .Thanks bud

RE: rebuild vs swap decisions
I have a couple thoughts that i have looked into a little bit but lets have some opinions about the following
my fan clutch is out from what i asume using it all the time to get back home recently and being everything will be tore down it would be ovb the time to replace it but i have been wondering
with all the new engergy saving types of parts coming up anybody have any thoughts pros & cons on
electric engine fan ??
fuel savings from it?
ovb dual would be safer to insure if one fails for what ever reason theres still one working .
any good quality kits on the market any one has seen or have experience with?

I also have steer air ride and the constant change in leveling I know screws with some things and have talked with a few others about how my drive line angles are changed and you can feel the differance in the drive ablity in the truck when it gets out of wack
but i also wonder if it is a common issue with the FLEX AIR SUSPENSION on Peterbilts

so is there any experience comments to the benefit over strait leaf spring type .its almost a hassle and they are expensive set up to have done and being I already have it i think i would replace the leafs to bring the quality of the ride and tire where back up cause I am having issues with steer wear CUPPING alot
I know bearings have a roll in that and shocks and that is a for sure replacement parts Im going to be changing

I have some pics i will include but I think im going to start a thread in the in the daily blog going forward with progresses and all .

Just as a little light at into your tunnel IronSled.... a properly tuned, maintained, and operated 2350 will be a good money maker.

Mine with 3.55s in the rear has ranged from 8.989 - 9.289 mpg since the beginning of this IFTA quarter. I run a 60 loaded and 40 empty, but when loaded I am 90% above 77k. Not sure the terrain or load you encounter, but a proper cm2350 equation (yourself included) will net you good mpg earnings which will transfer to money in the bank.


I’m constantly under the hood doing random checks and maintenance, but so far it has been a very profitable engine with the help and Insite of Rawze and the members of this forum.
