The problem: 
The removal of valve lifters from internal combustion 
engines requires extensive disassembly of an engine before 
the valve lifters are accessible. 	 Note: 
The solution: 
A valve lifter removal tool has been developed which, 
in most instances, can remove the valve lifter after removal 
of only the valve c o vers and push rods. 
How it's done: 
The removal tool is a threaded rod mounted in a 
tubular housing which is flanged and expandable at one 
end. The flange is designed to engage an internal groove 
in the valve lifter body. The tool is inserted into the 
valve lifter and aligned with the internal groove in the 
valve lifter body. The handle is then rotated counter-
clockwise, spreading the housing so as to engage the 
groove. The valve lifter is then removed by removing the 
tool from the push rod hole.
