International DT466 overhaul kits

International / Navistar produced thousands of reliable box trucks with the dt466 engine. Most of those engines are in the 4300 series and some are in the 4700 series. The dt466 engine has been running from 1995 to 2007. During those 22 years , most of the trucks on the road accumulated many miles. As results , many truck owners require an overhaul of the dt466 engine.

There are two types of overhauls. One is in frame overhaul and out of chasis overhaul. The first is easier than the ladder. The easiest way to do an overhaul of dt466 engine is to do an in-frame.The best way to do in frame overhaul on a dt466 engine is by using a genius or aftermarket dt466 overhaul kit. bellow are some of the dt466 overhaul kits we found.


(Navistar MaxxForce DT: 7.6 L)

DT is a line of diesel engines manufactured by the International Harvester Company between 1975 and 2016.  They are six cylinder inline engines, and are primarily used in medium-duty trucks and buses.

The DT466 variant of the DT line of engines displaces 466 cubit inches [7.63637 liters].

“International Harvester” is now called “Navistar International Corporation”.  The “International DT466” is now called “Navistar MaxxForce DT: 7.6 L”.

The Navistar DT466 diesel engine is a wet-sleeve engine. The cylinder sleeve is a separately machined part that fits into the cast cylinder bores.  This separate sleeve is in direct contact with the engine coolant, hence the “wet”-sleeve description.

DT466 Overhaul Kits

Rebuild Kit

There are two basic different kinds of rebuilds: in-frame and overhaul (out-of-frame).

IN-FRAME

An in-frame rebuild does not require that the engine be removed from the truck.  An In-frame kit does not contain gaskets for the front and rear body of the engine, only the main bearing, rod bearings, cylinder kits, upper gasket kit and oil pan gasket.

OVERHAUL (Out-of-Frame)

An overhaul requires the engine to be removed from the truck.  An Overhaul Kit comes complete with cylinder kits, main bearings, rod bearings, front and rear crankshaft seals, and complete overhaul gasket kit.

Prices:

In-Frame Kit:  $800~$1,000

Overhaul Kit:  $1,200~$1,500

Kits are also available without pistons and sleeves (at a slightly reduced cost)

Buying each part separately -vs- Buying a kit

It will cost almost twice as much to buy an entire rebuild kit one-piece-at-a-time -vs- buying a complete kit.  Add to that the aggravation of ordering every little piece one-piece-at-a-time—and the possibility of forgetting to order something—there is little reason to try to save a few dollars by ordering each piece separately.

 

If you are a professional mechanic, and you rebuild dozens of of these engines each year—there could be a good reason to keep a few extra parts.  If you are only rebuilding one engine, everything you need is in the kit.

 

Kits come boxed, sorted, and ready to go.

Escalation

A lot of parts need to be removed in order to do a rebuild.  Make a list of all the little issues that your truck needs, but you have been putting off.  Discuss these items with your mechanic before you start.  While your mechanic has everything apart, it might be a good time to do a few of those deferred repairs.  Any part that needs to be removed or disconnected is a good candidate for replacement/repair.

 

When you get the engine apart, you might find that there are other issues.  Be prepared to discuss additional repairs and service with your mechanic.

One Sleeve

If an engine has only one bad sleeve or piston, it is possible to repair that engine by removing the head and replacing that one faulty part.  Or replacing the sleeve, piston, bearings, etc of that one bad cylinder.  Then the head could be replaced and everything bolted back together.  This could, potentially, fix your engine’s problem—and save some money today.  However, if an additional problem were to develop or there are other undetected issues—you would have to take the engine apart a second time.  Each time you hire a mechanic to tear an engine down, there are labor costs.

 

You need to balance the potential short-term savings of only repairing/replacing the parts that are in immediate need of repair -vs- long term costs of having a mechanic disassemble your engine a second time.

 

Also, there are hidden operational costs in having a truck out-of-service a second time (or multiple times).

Things to think about

When you have repairs done to your truck, you should always very carefully keep the packing lists and repair records.  You never know what small piece of paper will be important years after the repair is finished.  You don’t necessarily need a fancy system of keeping records—just keep the papers in a file-folder, or stuffed into a large envelope.
