Like the title says if we have a pre emission 1999 Kenworth 900 with a 12.7 Detroit and a Fuller Eaton 13 speed that has been worked a little harder than average but runs good.
What would you expect that has all ready been repaired or replaced on the truck and what would need to be replaced to make that truck go another 1/2 million miles reliably ?
Million mile Truck what needs Repaired ?

Did you check the turbos ?
-
Did the seller give you any detailed information on What has been fixed?
-
I will make a list as you guys ad your thoughts
Turbo
Belts and Hoses -
all fluids, belts, water pump, dyno.

Oil sample is the best indicator, along with dyno.
Could need nothing inside the engine, could need everything.Depends, an oil sample will tell the tale. -
Hi tommy, I've heard of Detroit's going a million miles ( a Century I drove had 830K and never opened up) but not a heck of a lot more. At a million miles, you can bet everything has been replaced at least once. I guess I'd worry about electrics and suspension. It would be OK for a local truck, but I wouldn't want to do any cross country stuff with a truck with a million miles, although the ones that do probably know what they have done to the truck.

It is a Hypothetical truck as many trucks you look at pre emmision these days are right at a million or over so my question is what do you think has been replaced on the truck and what will need to be replaced to keep it going a 1/2 million ?
Lets say the truck dynoed good and has no blow by or in other telltale signs of incurring doom and we do not have any real past data on what has been repaired on the truck. -
So I would say this need repair on the engine
Belts and Hoses and all fluids
Bully Gear and Harmonic balance r
Clutch assembly
Turbo
a overhead
waterpump -
If you pull the boost hose off the turbo, you can inspect the impeller. Look for chips on the impeller, and whether or not there are signs of the impeller hitting anything. Spin the impeller...is there any play in the bearing? Is there an oil leak? No? Turbo should be fine.
Bring a flashlight and inspect the radiator. One of the things that gets overlooked on the old trucks is the radiator. The fins will eventually rot and fall out, and the radiator will leak at the tanks. With rotten fins falling out, that rad will not cool the way its supposed to. On a heavy load on a hot day, you will cook your motor.
Bring a creeper too. Go underneath the truck, top to bottom. Look at the air tanks...are they rusty? Are the fuel tanks leaking at the support straps? If theres something leaking, dust will accumilate at that point. Try to twist the driveshaft by hand. Both driveshafts. Wheel seals? Are the diffs leaking? Everything good?
Go and look inside. Usually, you can tell when a truck has been beaten to hell by the hood and the interior. Start her up and turn on the lights. If theres a problem, the relays should kick off if you leave the lights on. Get your circuit tester and check the pigtail. You want all gremlins fixed before you talk money. And I dont think thats unreasonable. I dont care what year the truck is. You dont buy a truck to take it home and fix it, you buy a truck to put it to work. If its not ready to work, its not a truck.
Fire her up and take her to a shop and have them inspect the tranny. Once they remove that cover, its really easy to see whether or not the transmission has been cooked. You will smell it. And the gears will be all funky looking, chipped, missing...etc.Mattflat362, dunchues, FinkPloyd and 2 others Thank this.
