Description

BMW:
• BMW M3 Base 4.0L (2008-2013)
• BMW M5 Base 5.0L (2006-2010)
• BMW M6 Base 5.0L (2006-2010)

FITMENT NOTES:
• Direct-fit OE-replacement transmission-side crankshaft / rear main seal (rubber) for the 2006-2010 BMW S85B50A 5.0L V10 (M5 / M6) and the 2008-2013 BMW S65B40A 4.0L V8 (M3) high-performance NA engines. Covers 3 source applications: M3 Base 4.0L 2008-2013 RWD (E90 sedan / E92 coupe / E93 cabriolet, S65B40A 32-valve DOHC NA V8 ~414 hp / 295 lb-ft, 8400-rpm redline - shares the same architecture as the S85 V10 minus 2 cylinders), M5 Base 5.0L 2006-2010 RWD (E60 sedan, S85B50A 40-valve DOHC NA V10 ~500 hp / 384 lb-ft, 8250-rpm redline, SMG-III 7-speed only US-market) and M6 Base 5.0L 2006-2010 RWD (E63 coupe / E64 cabriolet, S85B50A V10 ~500 hp). Replaces BMW OEM 11217838071. Spec: 3.94 in. inside diameter, 4.92 in. outside diameter, 0.49 in. thick. Rubber radial-lip seal. Mounts at the rear main / transmission-bell-housing side of the S65 / S85 block. Critical for preventing engine oil weeps onto the SMG-III hydraulic clutch / DCT clutch packs, a known S65 / S85 high-revving M-engine failure around 60,000-90,000 miles - accelerated by the high-RPM operating envelope (these engines see 8000+ rpm regularly, generating higher rear-main shaft speeds than typical street V8s/V10s). KOOL catalog reference CFW82037166.
