Abstract
A shim attaching/detaching tool for a tappet of an internal combustion engine includes as essential components an air supplying tube, an air blowing tube and a nozzle formed at an opening portion of the air blowing tube at the foremost end of the same. When compressed air is blown from the nozzle toward the shim while the air supplying tube is inclined at an angle of about 45 degrees and the nozzle is oriented toward the fitting portion of the shim fitted into a circular cavity, the shim is thrusted against the opposite side of the cavity and the compressed air is then introduced into the space below the shim through the gap appearing around the fitting portion of the shim, whereby the shim is floated up away from the cavity so as to enable it to be easily exchanged with another shim having a different thickness.
Claims7
A shim attaching/detaching tool for a tappet of an internal combustion engine wherein an annular side wall stands upright from the upper end of a cylindrical body of said tappet which upper surface is closed with an upper wall and a shim is detachably received in a circular cavity defined by said annular side wall to adjust a valve clearance as desired, comprising:
- an air supplying tube having a predetermined length and communicated with a compressed air supply source,
- an air blowing tube integrally connected to said air supplying tube, a flat nozzle formed at an opening portion of said air blowing tube at the foremost end of the same, a largest height of said flat nozzle being dimensioned so as not to exceed a height of said shim projected above the upper end face of said annular side wall when said opening portion of said air blowing tube is brought in contact with the fitting portion of said shim fitted into said circular cavity
- right-angled projections being formed on the opposite sides of said nozzle while extending in the forward direction.

- an air supplying tube integrally connected to said air supplying tube, and
- a flat nozzle formed at an opening portion of said air blowing tube at the foremost end of the same,
- upper and lower edges of said opening portion at the foremost end of said air blowing tube being dimensioned to have the substantially same radius of curvature as that of said shim, substantially right-angled projections being formed on the opposite sides of said nozzle while extending in the forward direction, a largest height of said flat nozzle being dimensioned so as not to exceed a height of said shim projected above the upper and face of said annular side wall when said opening portion of said air blowing tube is brought in contact with the fitting portion of said shim fitted into said circular cavity, thereby forming closed space between the opening portion of said air blowing tube, the annular side wall and the shim.
