Oil Seal Crank Front H10 OD79 ID65 (Bruck) (Petrol) (BMW 1 Series E81/E87 / F20/F21 / 3 Series E90 / F30 / 5 Series E60 / F10 / X1 E84 / X3 F25 / X5 E70 / Z4 E89) is designed to serve as a front crankshaft oil seal for various BMW petrol models across the 1, 3, 5 Series, and selected X and Z models. Positioned at the front of the crankshaft, this seal plays a critical role in preventing oil leaks from the engine by sealing the crankshaft end, helping maintain lubrication and engine efficiency.
This specific oil seal features outer and inner diameters (OD79 and ID65 respectively) to match the crankshaft and housing dimensions, ensuring a proper fitment for the listed BMW models including E81, E87, F20, F21, E90, F30, E60, F10, E84, F25, E70, and E89 chassis codes. Buyers should compare these measurements with their current seal to confirm compatibility.
The product carries the H10 bulb code identification, which aligns with the part’s category but here relates to its designated type within the manufacturer’s catalog. Its use is exclusive to petrol engines among the BMW models noted. When replacing this seal, ensure the crankshaft front area is clean and free of damage to avoid premature failure.
