摘要:
A process for remanufacturing a cylinder head that includes a worn or damaged rocker arm stand adapted to receive a rocker shaft to which at least one rocker arm is mounted, the steps including machining a channel in a surface of the worn or damaged rocker arm stand, securing an insert into the channel, and machining the insert to form a remanufactured inner facing surface. The remanufactured cylinder head includes at least one rocker arm stand that has a machined channel with a remanufactured insert secured therein, the rocker shaft being disposed adjacent the inner facing surface, not the rocker arm stand.
