International DT530 Engine

International DT530 Engines For Sale

The DT530 is known as an update of the 466 and has been the topic of many online reviews. The 1984 to 1992 DT engines used a Bosch MW injection pump, whereas 1993 to 1995 models showcased a Bosch P pump. All 1996 to current models used an HEUI (hydraulically actuated electronically controlled unit injector) fuel system The DT530 is available in standard and high-torque configurations. However, it was replaced in 2004 by DT/HT 570, which were then replaced in 2007 by the MaxxForce 9 and 10.

DT530 ENGINE REPLACEMENT OPTIONS

Regrettably, there is an array of issues that can halt your engine. Some instances mean that your only alternative is to replace it. However, every so often you may just need a few more parts to bring it back to life, or maybe, the engine merely needs a well-earned refreshment. We can appreciate that factors such as cost, time, and availability will determine your decision-making - so let us inform you of the pros and cons of a new engine from the dealer.

Remanufacturing Process

If you have the misfortune of being the victim of a serious internal engine failure but are lucky enough to be able to re-use some of its external components…a remanufactured 530 long block is a good decision indeed. In addition, a long block is also ideal if you are hoping to spend as little money as possible.

In order to achieve this, our team of machinists and engine builders will do a full core tear down, cleaning, inspection, and machining of the engine before it leaves our facility, guaranteeing every engine is in good condition each and every time.

However, it is crucial to point out that all of our 530 remanufactured long blocks are assembled with a mixture of both reman and new parts. We do not just recondition or refurbish old engine parts, instead, we entirely rebuild the old 530 motors back to OEM specs.

THOROUGH CLEANING

To avoid the early demise of both parts and the 530 entirely, we remove all the unwanted impurities by stripping the blocks, heads, rods, and camshafts which are then meticulously cleaned in a chemical jet wash or hot tank.

CRANKSHAFTS

The quality control department inspects the crankshafts after they are precision machined to exact tolerances, polished & magnafluxed.

 CYLINDER HEADS

To guarantee a proper sealing surface with the block, and to achieve a finish fitting with the latest gasket materials, the heads are resurfaced. Valve height is mic-d and every head is vacuum tested to assure correct valve seating.

CYLINDER BLOCKS

Magnetic is employed here to ensure the blocks are carefully inspected for any cracks or damage. In an effort to ensure the avoidance of cylinder head distortion after the head is bolted and torqued to the block, the cylinder heads are bored and honed to precise tolerances. In turn, this significantly reduces a prominent cause of engine blow-by. Block surfaces are machined and then inspected to achieve a proper finish.

CAMSHAFTS

Camshafts are inspected and precisely machined to provide the correct lift. Lobs are measured with a micrometer to make sure OEM tolerances are met.

CONNECTING RODS

Brand new bushings are installed and machined in all bushed rods. Every rod is then carefully inspected for any bend and/or twist. Connecting rods are cleaned, then machined to O.E.M. specifications and honed to the usual diameter of original equipment for even distribution of strain on the bearings.

NEW PARTS

Pistons and rings, bearings, gaskets and seals, and liners are all brand new as standard for our 530 long blocks. These new parts guarantee dependable performance and reliability during the course of the now extended life of your engine. The new parts are a mixture of OEM and Aftermarket when available.

REMANUFACTURED ENGINES STANDARDS

In addition, wearable parts are replaced every time, all the 530’s core material is then inspected and examined against the original specifications to ensure correct the dimensional tolerances are met. After all, the aim of remanufacturing is to make it as close to new as possible. Alternate parts are either new or requalified. If new, the parts are produced in the exact same manufacturing process as the original 530 engines. Testing is then performed to manufacturer specifications and original production standards.
