General information about this item

Product info
The B6-01-0744 piston ring set in 74.5 mm (1st oversize) is intended for reconditioned, oversize-ground cylinders in the BMW 600 engine, where it ensures complete combustion chamber sealing and oil control. It is used in conjunction with matching oversize pistons when the original cylinder bores are excessively worn or damaged. Precise machining of the cylinder, checking the ring gap, and careful installation are crucial to restoring a high-performance and durable engine after restoration.
