Subaru Tech Tip: Front Crankshaft Oil Seal Replacement Tip
Subaru has updated the procedures and tools needed to enhance retention of the oil seal and eliminate any chance of blocking the oil return passages in the timing chain cover.
Demystifying Scopes: Camshaft And Crankshaft Waveforms
Having to remove valve or front cover of an engine to check engine timing marks can rarely be completed in under an hour on most modern engines. But, capturing the waveforms from the camshaft and crankshaft sensors can be completed in under 30 minutes. This diagnostic approach can also diagnose circuit and sensor problems.
VIDEO: Crankshaft Vibration And Belt Components
Andrew Markel reveals the details on crankshaft operation and how the power pulses cause vibration and stress on the belt and the components it is attached to. Sponsored by Auto Value and Bumper to Bumper.
MEYLE Adds Crankshaft Sealing Flanges For 2,000 Vehicle Applications
The company says that sealing flange modules are important to ensure effective sealing at the engine crankshaft.
Lunati Offers Voodoo Crankshafts
The backbone of an engine and the foundation of the bottom end is the crankshaft. Voodoo Crankshafts from Lunati are engineered from 4340 non-twist forged steel that is known for its durability and strength in high-performance applications, said the company.
Crankshaft Grinding Tips
Working in technical support, hardly a day passes without at least one crank grinding question. For the most part, these questions involve properly using, dressing, mounting and balancing the crankwheel.
Tech Tip: Audi 2.8L V6 Rear Crankshaft Seal Leaks After Replacement
Oil may leak from the rear crankshaft seal after seal replacement due to the seal lip rolling while installing the new seal. This condition affects 1996 A4 with 2.8L V6 (Engine Code AFC). When replacing the seal, the new seal is supplied pre-installed in the flange.
GM Tech Tip: Crankshaft Rear Main Oil Seal Leaks in Some 60-degree V6 GM Engines
Some GM owners may complain about external oil leaks from these engines. Before replacing the new design rear main oil seal, be sure the PCV system is operating correctly.
Tech Feature: Understanding the Differences, Challenges Between Crankshaft Position Sensors
There are two basic types of crankshaft position sensors: Magnetic Field (Variable Reluctance) and Hall Effect. The magnetic type uses a magnet to sense notches in the crankshaft or harmonic balancer. The Hall Effect crank sensor uses notches or shutter blades on the crank, cam gear or balancer to disrupt a magnetic field in the Hall Effect sensor window.
Crankshaft and Camshaft Position Sensor Diagnosis
Nothing is more frustrating than diagnosing an intermittent cranking, no-start complaint with no diagnostic trouble codes (DTCs) and no apparent failure pattern. Much of the time, the cranking, no-start complaint lies with a failing crankshaft or camshaft position sensor. Many of these failures can be heat-related and might require several warm-up cycles to duplicate.
