PURPOSE: A method for sealing a stud bolt installed at a bonding groove of a cylinder frame is provided to reduce a manufacturing period and to reduce manufacturing processes by injecting silicon between a stud ball and a combing groove. CONSTITUTION: A method for sealing a stud bolt installed at a bonding groove of a cylinder frame comprises next steps. Silicon(52) is inserted between the bonding groove and stud bolt. The silicon prevents the inflow of foreign material being between the bonding groove and stud bolt. The stud bolt is inserted in the combining groove. The silicon spreads over the exterior of the stud bolt. The stud bolt, in which the silicon is hardened, is inserted into the bonding groove. The injected silicon seals between the bonding groove and the stud bolt.
