发明名称 Automotive valve lifter and push rod extractor tool
摘要 This valve lifter and push rod extractor tool is designed to quickly and easily remove hydraulic valve lifters and push rods in automobile engines without removing the engine head from the engine block. The device utilizes the existing thread bores on the engine which normally secure the valve cover in place to mount the tool temporarily on the engine head. The device has a mechansim which is able to reach into awkward spaces in the engine with a clamp apparatus that can be temporarily attached to a valve lifter or push rod and then produce a sufficient pulling removal force which can be applied to either part until it comes free from the engine.
