BMW 3 Series E36 M40 Front Crankshaft Seal | ELRING 748.889
BMW E36 Front Crank Seal ELRING (M40 Oil Leak Solution)
ELRING 748.889 | Original German Viton® Quality | Timing and Crank Protection
- Timing Belt Failure Disaster: M40 engines are timing belt driven. If the old BMW E36 Front Crank Seal starts leaking oil, this hot engine oil seeps directly onto the rubber timing belt. The lubricated belt deteriorates quickly, skips teeth, or breaks! When the belt breaks, the pistons hit the valves, and the engine is completely destroyed. The moment you see oil sweating from the front, replacing this seal is a vital NECESSITY.
- Master Craftsmanship: When installing a new BMW E36 Front Crank Seal, it is crucial that the technician does not SCRATCH the steel surface of the crankshaft while trying to remove the old seal with a screwdriver. A scratched crankshaft will continue to leak oil, no matter how good the seal is.
Specially imported for BMW's legendary E36 chassis with timing belt 4-cylinder (M40) engines, the ELRING brand BMW E36 Front Crank Seal is here to cut through those dangerous oil leaks at the front of the engine like a knife! This rubber ring, which is responsible for keeping engine oil inside at the point where the crankshaft meets the front pulley, hardens over time due to the heat and friction generated by high RPMs over tens of thousands of kilometers, losing its sealing capability. An old and hardened BMW E36 Front Crank Seal that leaks oil down from the front cover, leaving the timing belt in oil and creating black stains in your parking lot, is the biggest indicator that your vehicle is on the brink of breaking down. To protect your engine from that massive timing belt failure and rectification costs, you can reset the front sealing of your engine block with this brand new BMW E36 Front Crank Seal, produced with "Das Original" ELRING quality, the factory (OEM) sealing supplier of German automotive giants. Made from fluorocarbon (Viton) material that is fully resistant to high temperatures and the acidic nature of synthetic oils, this imported BMW E36 Front Crank Seal wraps around your crankshaft like a clamp, providing a definitive and permanent solution to oil leaks.
- Vital Engine Protection: By preventing engine oil from reaching the timing belt, it definitively stops the belt from deteriorating, fraying, and the engine from bending valves (engine eating).
- Perfect Oil Sealing: A brand new BMW E36 Front Crank Seal traps oil inside the engine block, eliminating oil consumption issues and that ugly sludge on the front surface of the engine.
- ELRING Das Original Quality: Manufactured from premium materials that show maximum resistance to friction, excessive engine temperatures, and high pressure, meeting original BMW standards.
- Flawless Fit: Fits millimeter-perfect into its slot in the front cover, and when installed with proper craftsmanship, it absolutely does not require any additional silicone or liquid gasket.
