Mazda L3G610602 — Crankshaft Front Oil Seal
Overview
Front crankshaft oil seal Mazda L3G610602 retains engine lubricant within the crankcase at the timing cover interface. Manufactured from fluoroelastomer (FKM) compound, this genuine seal resists thermal degradation up to +200 °C and tolerates synthetic oil additives. Key dimensions measure 37 mm internal diameter, 50 mm external diameter, and 6 mm width. The sealing lip incorporates a garter spring to maintain continuous radial pressure against the crankshaft nose during operation up to 7000 rpm. Supplied under genuine OEM reference Mazda L3G610602, this component supersedes earlier part numbers L3G610602A and L3G6-10-602. Precision moulding prevents fluid migration along the rotating shaft journal, protecting auxiliary drive belts from contamination.
Fitment covers Mazda 3 BK and BL models (2003–2013), Mazda 6 GG and GH models (2002–2012), Mazda 5 CR and CW models (2005–2015), and Mazda CX-7 ER models (2006–2012). Suitable for 1.8 L, 2.0 L, and 2.3 L MZR series petrol engines (L8, LF, and L3 engine codes). Replacement is required when oil weeping appears around the front crankshaft pulley, when crankcase fluid loss is detected, or following hardening of the sealing lip over extended service intervals past 120 000 km. Installation restores fluid retention within the timing gear compartment and prevents oil saturation of the serpentine belt assembly.
