DT466E Maintenance and Care

Iím looking into firing up my IH 3800 w/ a DT466E for the first time in almost 6-7 months. Iím having trouble finding operator and service manuals for my chassis and drivetrain. I want to ensure that the proper startup procedures are always followed.

Iíve always been a stickler for maintenance. I want this engine to last as long as I can make it. Is there anything special for starting I should be aware of? Should I just crank it and let it idle, or should I bump it up to a high idle of say 12-1500 RPM after ten or so seconds once started?

Any thoughts and contributions are welcome!

While I can't say for sure what any manual would tell me -- my pre emissions DT466E I have no issue letting it warm up at idle. It's not fast to do so, but it's charging 13.7-14.1v at idle, and I will generally let it come up to 100degress before I move it.


As for sitting for half a year -- if it has a drain on the fuel filter to let the water out, I'd hit that, check the oil, check the air filter for mice.

Fired it up and ran like a top. Nothing crazy happened which IMHO is the best way

Its my understanding that warm-up time is fairly inconsequential as diesels don't warm-up like gasers do at idle I personally start it and once oil pressure is up its good to go like 5 seconds

Tis true, they don't warm like a gasser, but they do still have heat expansion during a warm up, and on a barge this big, I like to give it a chance to barf in the driveway before I get going. God knows if you're driving it, you're not in a hurry anyway!

The other day I cranked the TC2000 up in the sloped drive. Didn't have enough power cold to move it up the drive, had have a tow truck pull me up. I was later told these things don't make good power until they are warm.

I'd look at your transmission that's probably at fault there

Not saying. That my way is the "right way" by any means but I've driven a lot 7.3 motors and. Found no ill effects from it

there are times i just start mine up and go when its really cold out.. I like to let it warm up... its hard on the oil system toi run the revs up when the oil is thick goo... pegs the gauge at 80 PSI.. the relief springs cant leed off enough pressure when its winter cold..



with the old computer mine did have terrile manners.. once i updated to the new computer and latest firmware its winter manners got MUCH improved..



id rather let it warm uo at least 10 minutes or longer efore driivng.. ut sometimes im in a hurry.. I just kick it over and gone..

What service intervals do people usually use for RVs/Skoolies? Hours for fuel filters/air filters, engine oil/filters and trans fluid/filters, and miles for rear axle lube? I understand people here will change coolant religious after a year or possibly two. Something I still have to do on my DT466E to set a baseline. I’m also trying to find some info about bleed the hydraulic braking system on mine. Are the pressures exponentially higher than in a passenger car with the ignition off? Or is it safe to crack a bleeder after a few pumps of the brake pedal? Last thing I’d ever want is hydraulic fluid in the eyes again haha.

Bleeding is like a car same steps but don't bother trying to vacuum bleed it with hand pump

When I bought mine originally, I changed all fluid filters and air filter.

Since then, I change the oil, oil filters, and fuel filter once a year.

Air filter has a vacuum monitor on it, so I simply check that. It hasn't needed changed yet.

Trans filter was changed again after 5 years.

I've only ever checked/adjusted my coolant with test strips. It's never been changed to my knowledge.

It's a good idea to flush your brake fluid. Most people don't know that it's hygroscopic, and after 5 or so years can start to ruin the seals in the system.

Your braking system on the bus shouldn't have any crazy pressures, it will just be a larger system then a passenger car. Slide one end of a 1/4" clear nylon tube from the hardware store over the bleeder and the other into a water bottle that is half full of fluid. That way you don't end up with a fluid mess or in your eyes.
