One New Aftermarket Replacement Piston Ring Set Fits John Deere (Fits JD) Two-Cylinder Tractors and Crawlers
This standard-bore (STD) aftermarket piston ring set is a direct replacement for the original Fits John Deere 2C7741.STD ring set, designed for the classic two-cylinder Fits John Deere Model B engine family. It restores compression and oil control in engines with standard (un-rebored) cylinder bores, making it an essential part for engine rebuilds and overhauls on early unstyled Fits John Deere tractors and orchard/crawler variants.

- Oil Rings: 4 rings per set at 3/16" (0.1875")
- Complete 2-cylinder set
- Size: Standard (STD) - not oversize
