OBR Remanufacturing Process
OBR's remanufacturing process begins with a used engine core that is completely disassembled, cleaned, and inspected. Components are checked for condition and specifications, and parts that do not meet requirements are replaced during the remanufacturing process. OBR long blocks are assembled with the cylinder heads installed and timed on the short block and are built to meet OE specifications.
