If they would have taken the time to put alignment pins in the seal retainer their seal would have worked a lot better. Those stock seals were cheap to manufacture. DIRECT REPLACEMENT - This is a high-quality aftermarket alternative to OEM 3164780 (seal/sleeve kit PN 4965569).

BENEFITS - Specifically design to install and remove the crankshaft rear seal & wear sleeve, saving time and reducing risk of crankshaft seal surface damage during removal. You might also want to try testing a product yourself BEFORE you condem it. It will fit the newest Cummins seal perfectly. Some times its best to not look a gift horse in the mouth. YOU WERE NOT THERE ! I think I have only 20 or so of them left.

We had hundreds of leaking seal warranty claims when the trucks were new. The rear main seal on an engine is between the engine and transmission. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks. The rear main seal is an unlikely source. 2 years ago I sold hundreds of them to the fleets before I ever offered them to the consumers. An example of this is a rear main seal leak. External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. I sold almost 1000 of those seals in just a few short months. And where exactly did you get your engineering degree ?Īnd heres another news flash for you. 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.Your right about the road draft tube. These engines use many torque to yield fasteners that require bolt “stretch” to maintain adequate clamp loads. DFC considers this practice unacceptable and installs new cast SBI guides in every cylinder head we remanufacture. Instead of just testing old springs and reusing like most remanufacturers DFC installs brand new SBI valve springs that are still tested for proper spring pressure on every cylinder head we remanufacture.Ĭommon industry practice is to check guide clearance and if within specification, not replace. Our Rottler equipment allows us to remanufacture the Cummins engine to tighter than OEM specifications resulting in a longer lasting more efficient engine assembly. By utilizing a high quality silicone we are able to prevent this from occurring. Slik66 : 3 - 08-Jun-08 Reply: Slik66 : 08-Jun-08 : Old engine maybe sump has goneporous or rear main seal.

The front covers on the Cummins engines use a paper gasket that is known to fall inside of the front gear case causing a significant oil loss and expensive repair. rear main seals: Popular Searches: 40+ applicable posts with matching content. Our production engines are typically matched with near identical weight piston and connecting rod assemblies giving our customers a smoother running and quieter engine. Most companies will re-grind and install used again.Įnsuring 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. Our engines have oversized SBI valve seats installed with at least 0.008” crush eliminating this from occurring.ĭFC installs new valves from MAHLE/Clevite or SBI in every cylinder head we remanufacture. The factory valve seats were only installed with 0.002”-0.003” crush which can allow them to fall out prematurely causing engine failure. The 2003-2007 model engines come upgraded from DFC with additional piston cooling preventing premature piston erosion of the piston crown from failed injectors. DFC silicones the oil pans instead of using the factory gasket as they are common to compress and start to sweat prematurely.
