Abstract A preferred form of follower includes an inverted cup-shaped body that fits over a valve stem of an overhead cam engine and includes a threaded central bore which receives a threaded plug. The bottom surface of the plug engages the valve stem and the top of the plug is provided with a square bore. A cap fits over the body and plug and is provided with a downwardly depending square boss that is fitted into the bore of the plug. The cap is provided with slots engageable by a screwdriver to rotate the cap and thus screw the plug axially inward or outward of the body to adjust the clearance between the cam and the valve stem. A plurality of circumferentially spaced locking holes are provided to be selectively engaged by a pin depending downwardly from the cap. A second form of the invention includes an inverted cupshaped body having an upwardly extending threaded boss. A cap overlies the body and is provided with a mating threaded bore. A recess is provided in the cap for rotating the cap and providing access to a set screw inserted through the cap for locking engagement with the threaded boss.
An adjustable cam follower comprising an inverted cup-shaped body with an open end embracing a valve stem and having a threaded central bore; a plug threaded into said bore; a cap overlying said plug and said body; means slidably interconnecting said cap and plug for rotation of said plug with said cap thereby raising or lowering said plug relative to said body while permitting relative axial movement between said cap and said plug; means for rotating said cap; and means for releasably locking said cap and said body against relative rotation when in a normal operating condition.
