ABSTRACT:
A relatively simple device for measuring such variables as piston wrist pin and connecting rod big end clearances in internal combustion engines includes a cylindrical casing with a threaded front end for mounting in a spark plug hole; an elongated, arcuate wire probe slidable in a sleeve on such front end for engaging the top end of a piston; a plunger slidably mounted in the casing and extending beyond the other end of the casing to a micrometer for measuring piston movement; and air and oil lines extending through the casing to such front end for introducing a vacuum, air or oil to the cylinder for various measuring procedures.
