I own a diesel repair shop and we do 60%pickups and 40% heavy trucks. We sort of specialize in performance and tuning diesels vs. just repairs. Anyway, from what I see the 6.7 has minimal problems compared to the 6.4's and 6.0 powerstrokes. It seems we get one now and then that is just a problem child and has issue after issue, but overall the majority of repairs come back to the emissions system. I would not run one of these engines in a medium duty truck and expect it to last. They are just not stout enough for that unless they adjust some of the internals. Ill tell you though, the power we get of these engines is impressive.

I should clarify. It costs me $700 because I remove the housing and drop it off at the repair shop. Mobile services for my area is about twice the price. Axle Surgeons came out and did a buddy of mines trailer on the side of the road. Remove and replace 1 spindle. Charged him $3500.

Called a spindle in the US. I've had a few repaired. Cost me about $700 per spindle to cut off the old and weld in new. Never had any issues with the process.

Start by checking for bent push rods. They are the weak link and typically bend first causing excess lash. If you had enough ether in that thing to cause it to runaway I wouldn't be surprised if you have other more serious issues.

As long as its oil rated and can tolerate the heat. Make sure your inner diameter is the same or larger. Also the line has to be downhill with no major bends to restrict oil flow out of the turbo. I've seen more than a few turbos lose the oil seal due to a poor drain line.

I use alumi-tank as well. They are easy to deal with and the tanks they build are very nice. Last set cost me about $650 a piece for polished tanks on the CL.

My buddy works at the company down the road from the Mack plant that sets up the trucks for delivery like this. Its pretty neat the way they do it. I can tell you I would never want to be driver though. That's a rough job. If its only a single truck they make you tow a car and drive back, which of course is not paid.

Nice try! The only place this motors heading is to my engine stand for tear down.

I had some time to pull the motor out of the new truck I purchased. I've pulled a lot of engines but this really shows you just how bulky an E9 is. A 3406 or ISX is a big motor on the ground. The Mack is just like a body builder with giant upper body muscles. Almost comical. The motor next to it is a 5.9 Cummins out of a Dodge pickup.

I recently paid $6500 for a E9 engine with a Mack T2180 trans. The problem you run into is everyone wants a core and if you don't have one its big money to buy it outright. I'm always looking for E9 parts... at the right price.

Is there are problem with the braking or you are just looking to go bigger?

I drove for 2 companies that use drivecam. Both would use it a a tool for punishing drivers. Telling you your following too close, or going to fast for the curve, or drinking a coffee... I always hated it. Until one morning after loading a trailer full of LPG and heading out and a car goes right through a stop sign and we collide. I was able to veer to the oncoming lane so it was a glancing blow and nobody was hurt but the damage was done. I am now a firm believer in drivecam! It showed the whole event, and I was in the clear.

There are a lot of liars out there and drivecam is a cheap and easy insurance.

I second dieselspec. They have a network of dealers that can tune the emissions equipment out of your truck. It can get a bit pricey.

All parts are still available individually. Mack prices the individual pieces 10x what it would be to get you to buy the whole kit. For example I can get a complete engine kit from Mack for $4300. If I were to but a single piston/liner its $875. Crazy right? Ill pull the motor now but i'll have to wait a bit to get the engine back together with the holidays coming up.

Ill say that the company that had this truck spared no expense for repairs. That's one reason I bought this truck. It is not all cobbled together.

I have a truck with 4.17's that I'm looking to jump up to 5.02's. Same thing 44k on camelback with a 300 HP E6. Running a 55ton lowboy we need more reduction in the rears. Its a shame your all the way in IL. The 5.02 is a great mix for heavy operating. It give you good reduction but still reasonable on the highway.

Wasn't that the truck on ebay with the engine knock?

Yea I first saw it on Ebay. Sounds like a dropped valve seat.

1998 was the last year of the E9's in the states correct?

I had one that after 2 different pullers and various methods of removal it ripped the thread off the top of the injector. Ended up welding a nut to the top and using a puller with an air hammer. Came out with the sleeve.

I would say your best bet at salvaging them is remove the studs and use 2 very large prybars while twisting like said above.

Here is a picture. Not the easiest spot to snap a good photo... Its a simple piece of angle across the valley with another piece of angle for the pump to sit on.

That's sounds very similar to what I'm experiencing. At 1500 to 1600 rpms it will just start to bounce the throttle. I can either back it down or push through it. I found 2 broken throttle springs so m going to try that first. Defiantly not a fan of the air throttle, they are too imprecise.

Thanks so much! That is exactly what I need.

Anybody with an e9 that has an inline pump with air throttle I could use your help! I need a picture of the throttle return springs. I'm trying to figure out the way they are supposed to go. There are 2 brackets that go in different directions for springs.

Not sure if its still available but I saw this one on craigslist. Post id: 5203790186

1988 superliner with 58k's in Brooklyn. They are asking $13,500.

A borg warner S480 is a nice up-grade even for stock fueled engine. It takes a few modifications to get them plumbed in but its worth it. You can get a brand new one, not reman, for about 1k.
