Title: Engine valve clearance adjusting method
Inventor: YAMAHARA KANJI
IPC: F01L1/20
Filed: 2004-07-20
Abstract: [PROBLEMS] To solve the problem that a technique which allows anyone to adjust a tappet clearance in an engine valve without requiring a special skill sometimes fails to provide an accurate adjustment since the abutment seat of a digital gauge for detecting a displacement magnitude is not a rocker arm itself and since the abutment position is deviated from the axis of an adjusting screw, thus requiring a readjustment or the like. [MEANS FOR SOLVING  PROBLEMS] In a method for adjusting/confirming the tappet clearance between a rocker arm adjusting screw and a valve stem, the adjusting screw is driven in until the face of the valve stem is separate from the valve seat, whereupon the adjusting screw is loosened for retraction while measuring the torque, so as to find the adjustment origin on the basis of the measured torque value, and the adjusting screw is loosened by an amount corresponding to a clearance set specified value from the thus-found adjustment origin, thereby confirming this clearance set specified value by a displacement gauge.

Patent CA-2549773-A1 (CA)
Inventor: FRAZIER BRADLEY L
IPC: E21B17/14
Filed: 2006-06-07
Abstract: A guide shoe that utilizes an eccentric nose attached to a cylindrical body that has spiraled, ridged blades extending outward from the body. An orientation system is attached between the body and a hollow shaft. The orientation system is designed to allow free rotation of the body and nose about the shaft during the insertion of the tubing into the hole. It does this by providing clearance between a pawl and notches on the cylindrical body. Indexing of the eccentric nose is provided by a slight retraction of the tubing string in the well hole. Friction between the well hole and ridged blade causes the cylindrical body to rotate about the shaft and lock into an oriented position.  The guide shoe is attached to the tubing string by a threaded female connection mating to the matching male connection on the tubing string.
