DFC Diesel Rebuilders prides itself in being the highest quality product on the market. This is why we can back our engines with a 5 year 160,000km warranty that we stand behind.

Our engines have been re-manufactured to factory specs using all new industry recognized name brand parts that meet and exceed OEM specifications. The block has been professionally machined and bored for use with the next over-sized piston NO SLEEVES ARE USED.

All New OEM or equivalent pistons, rings, and gaskets are used to ensure quality and consistency of our engines. Our Re-manufactured Cylinder Heads have all new seats, guides, valves, and stem seals as well as being resurfaced and magnafluxed.

Complete Long Block Includes:

  • Long Block
  • Injectors
  • Turbo
  • Oil cooler
  • Does not include CP3 fuel injeection pump
Oil Pump

All DFC Duramax engines feature an EDM doweled oil pump shaft with a hardened dowel installed locating the gear to the oil pump shaft preventing slipping and the subsequent oil pressure loss.

Machining

Our Rottler equipment allows us to remanufacture the Duramax engine’s to tighter than OEM specifications resulting in a longer lasting more efficient engine assembly.

Head Gasket Sealing

Some model years of Duramax engines are more susceptible to premature head gasket failure. To reduce the chance of this all DFC long blocks come with new head bolts, revised torque sequences and digitally recorded torque values to ensure reliability.

Core Criteria

Ensuring every engine is built to the same high quality standards as the next DFC is very strict on what is remanufactured rejecting components that require considerable “restoring” to acceptable specifications.

Valve Springs

Instead of just testing old springs and reusing like most remanufactures DFC installs brand new SBI valve springs that are still tested for proper spring pressure on every cylinder head we rebuild.

Valves

DFC installs new valves from MAHLE/Clevite or SBI in every cylinder head we remanufacture. Most companies will re-grind and install used again.

Cast Guides

Common industry practice is to check guide clearance and if within specification, not replace. DFC considers this practice unacceptable and installs new cast SBI guides in every cylinder head we remanufacture.

Weighed Rotating Assemblies

Our production engines are typically matched with near identical weight piston and connecting rod assemblies giving our customers a smoother running and quieter engine.

Torque Specs

These engines use many torque to yield fasteners that require bolt “stretch” to maintain adequate clamp loads. In addition to not just following the OEM procedures for tightening sequence our assembly technicians record the achieved torque load through use of digital torque wrenches ensuring no fastener will come loose over time.
