The Mopar Difference – Dyno-Might: Mopar Proves its Mettle .
Every automobile manufacturer tells the same story: that genuine original equipment parts have a long list of advantages over aftermarket or salvaged parts.
That same advantage applies to authentic remanufactured parts and assemblies. When it comes to Mopar® Remanufactured products, the advantages start with the access Mopar has to the original design specifications from which the reman engineers can develop a surefire process with proven, quality parts. The engine design is tested to standards that are mostly unheard of in the aftermarket.
Recent benchmark testing performed for Mopar involved a 4.7L Reman engine direct from the Mopar Reman inventory. When pitted against a competitive 4.7L Reman engine purchased from a national auto parts store, the Mopar Reman engine passed the testing with flying colors. The aftermarket engine failed.
Both engines were subjected to the standard by which all Mopar Reman engines are tested. Mopar uses a 625-hour general durability dyno test on a minimum of three design engines. A complete teardown and inspection of all internal components follow the dyno runs. The results from this benchmark test were, well, explosive.
After a mere 15 hours on the dyno, the aftermarket engine suffered a catastrophic failure. When a rod failed due to an inferior remanufacturing process, it led to massive internal damage and total engine failure.
✦ Blocks, heads and crankshafts are painstakingly machined to tolerances matching proprietary FCA US LLC specifications
✦ Engine components are subjected to over 20 checks and tests on state-of-the-art test equipment
✦ Every Mopar® remanufactured engine is cold tested to validate the build
✦ Torque-to-turn, compression, oil pressure specifications and other critical engine parameters that are proprietary to FCA UC are monitored and recorded to ensure quality, lasting performance and reliability
During teardown analysis, Mopar® discovered it has several advantages over the aftermarket:
✓ Mopar® replaces wear components in mandatory replacement locations with 100 percent new O.E. parts (Fig. 1) – the aftermarket manufacturer does not. The aftermarket remanufacturer also reused torque-to-yield connecting rod bolts (Fig. 2). This resulted in a connecting rod failure (Fig. 3) and ultimately the catastrophic failure of the aftermarket remanufactured engine.
✓ Mopar bearings look brand new after 625 hours of testing (Fig. 4) – the aftermarket bearings showed signs of significant wear and fatigue after only 15 hours (Fig. 5).
✓ Mopar maintains proprietary O.E. surface machining specs and deck heights, and uses O.E. approved processes. This aftermarket remanufacturer used copper sealant spray on the head gasket to mask potential sealing issues – not an O.E. approved process.
✓ Mopar remanufactured engines use the correct replacement parts and include the latest engineering upgrades to ensure optimal performance and reliability.
