Original BMW Rear Crankshaft Seal Kit for BMW 5, 7, and 8 Series, M5, X5, Z8, and Land Rover Range Rover (1994–2005)

Built for the rear main seal job on BMW's M60, M62, and S62 V8 engines, this Original BMW crankshaft seal kit, 11-14-1-436-109, packages the rear crankshaft seal, the seal carrier, and a steel gasket for the 5, 7, and 8 Series, M5, X5, and Z8. BMW's parts data calls the assembly a set of covers, reflecting the carrier housing that closes off the back of the engine block around the crankshaft. A rear crankshaft seal sits where the crankshaft exits the back of the engine and seals the spinning crank against the stationary carrier, keeping oil inside the engine. The kit is made in Germany, weighs 498 g (1.1 lb), and is sold as one complete set. BMW has produced this version since May 1996.

This kit replaced the earlier 11-14-1-745-093, and BMW rates the change as exchangeable retrospectively, meaning the current kit also fits engines built with the older part. Because the seal comes with its carrier and the steel gasket, the parts that meet at the rear of the block are renewed together rather than reusing an aged carrier. BMW's parts data shows the kit on the E34 530i and 540i with the M60, the E38 730i, 735i, 740i, and 740iL with the M60 and M62, the E31 840Ci and 840i, the E39 535i and 540i with the M62 and the M5 with the S62, the E53 X5 4.4i and 4.6is, and the E52 Z8 with the S62 plus the Alpina V8. A leaking rear seal typically shows as oil near the transmission area at the back of the engine, and oil reaching hot components can produce a burning smell.
