Original BMW Connecting Rod Bolt, 53 mm, BMW 3, 5, 7, and 8 Series (1982–1995)

This Original BMW connecting rod bolt, part number 11-24-1-713-342, clamps the rod cap to the connecting rod on M20, M21, M42, M50, and M70 engines in BMW 3, 5, 7, and 8 Series cars built from 1982–1995. BMW specifies a 53 mm length for this bolt and a weight of 30 g (1.06 oz). A connecting rod bolt holds the split big end of the rod together around the crankshaft journal, and its clamping load keeps the upper and lower bearing shells seated inside the rod. Production of this part number began in September 1987.

Original BMW Parts carry a 24-month parts warranty.

This bolt supersedes the earlier part number 11-24-1-267-147, and BMW rates the change as exchangeable retrospectively. That means the newer bolt can go into engines that left the factory with the older number, so 11-24-1-713-342 is the number to order for both early and late builds of the engines covered here. A single part number spans the M20, M21, M42, M50, and M70 engine families, which makes this same 53 mm bolt common across E28, E30, E32, E34, E36, and E31 bottom-end work.
