Patent ID: 8196802

Claim:
A method for fixing a guide block in a gland of a seal device for a rotary shaft, the gland having an inner gland surface that defines a central hole and a fluid passage extending annularly around the central hole, and an outer gland surface surrounding the inner gland surface, the method comprising the steps of: providing the gland with a fixing hole that extends radially through the inner and outer gland surfaces; disposing the guide block in the fluid passage; inserting a fixing member into the fixing hole; connecting the fixing member to the guide block; placing an outer block surface of the guide block in abutment with the inner gland surface; filling a welding material in the fixing hole around the fixing member, thereby retaining the fixing member in the fixing hole; and cutting a portion of the fixing member that extends outwardly of the fixing hole, followed by a grinding process to make the fixing member flush with the outer gland surface.
