The 11L became fairly popular in buses due to its efficiency and electronic control. This engine practically pioneered the existence of electronically controlled diesel engines. However, the 11L ceased in 1998, allowing the 12L to pick up from where it left off. However, despite the popularity of Both of these engines, the 12L also died out in 2007. The 14L was just as popular, especially in Freightliner trucks, but in 2011 it was discontinued and replaced by the DD15.

The 60 series was described as ahead of its time as it utilized a single overhead camshaft to operate its intake valves, exhaust valves, and fuel injector plungers. Like all engines, the 60 series also suffered some defects. A significant problem for the pre-2002 engines was defective wrist pins, these occasionally caused the piston crowns and skirts to separate, It wasn’t exactly a common problem, but it did cause some trouble.

Remanufacturing Process

If someone is unfortunate enough to witness a serious internal engine failure but is fortunate enough to be able to re-use some of their external components…a remanufactured Detroit 60 series long block is a good way to go. Additionally, a long block is also perfect if you are hoping to spend as little as possible.

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, ensuring every engine is in good condition each and every time.

However, it is important to point out that all of our 60 series remanufactured long blocks are constructed with a mixture of both reman and new parts. We do not recondition or refurbish old engine parts, instead, we completely rebuild the old Detroit 60 series engine back to OEM specs.

Thorough Cleaning

In an effort to avoid the early demise of both parts and the 60 series itself, we remove all impurities by stripping the blocks, heads, rods, and camshafts which are then thoroughly cleaned in a chemical jet wash or hot tank.

Crankshafts

Crankshafts are precision machined to exact tolerances, polished & magnafluxed, then thoroughly inspected by our quality control department.

Cylinder Heads

To ensure a proper sealing surface with the block, and to achieve a finish compatible with recent 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 particle is used so blocks are carefully inspected for any cracks or damage. 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 eliminates a cause of engine blow-by. Block surfaces are machined and then inspected to ensure 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

New bushings are fitted and machined in all bushed rods. Every rod is carefully inspected for bend and twist. Connecting rods are cleaned, then machined to O.E.M. specifications and honed to the standard diameter of original equipment for even distribution of stress on the bearings.

New Series 60 Engine Parts

New parts such as pistons and rings, bearings, gaskets and seals, and liners are all brand new as standard for our 60 Series long blocks. These new parts ensure dependable performance and reliability throughout the life of your engine. The new parts are a combination of OEM and Aftermarket when available.

After all, the aim of remanufacturing is to make it as close to new as possible. Replacement parts are either new or requalified. If new, parts are made in the exact same production processes as the original 60 series. Testing is performed to manufacturer specifications and original production standards.
