Abstract
Embodiments of a device and method for removing a valve spring from an engine are herein disclosed. In one embodiment, the device includes a base component with a compressor component removably connected to the base component via an elongate member threadedly engaged with the base component. A fastener may threadedly engage with the elongate member to reversibly keep the compressor component in place. The base component is configured to engage with opposing vertically-extending components on a cylinder head while the compressor component is configured to simultaneously engage with a valve spring. When rotational force is applied in a clockwork direction to the fastening component, the compressor component is forced in a downward direction thereby compressing the valve spring for subsequent removal thereof.
Claims18
A device for removing a valve spring, comprising:
- a base component adapted to engage with opposing vertically-extending components on a cylinder head;
- and
- a compressor component slidably engaged with an elongate member, the elongate member threadedly engaged with an opening passing through a center of the base component.
A device for removing a valve spring, comprising:
- a base component, the base component comprising a U-shaped member with two outwardly extending projections extending from terminating ends of the U-shaped member;
- an elongate member at least partially engaged with an opening passing through a center of the base;
- and
- a compressor component, the compressor component comprising a vertically-extending back support having a proximal end and a distal end wherein two outwardly-projecting prongs extend from the distal end of the vertically-extending back support, the compressor component slidably engaged with an elongate member via a bore through the vertically-extending back support.
A method of removing a valve spring from an engine, comprising:
- positioning two horizontally and outwardly-extending arms of valve spring tool on opposing vertically-extending components on a cylinder head;
- securing the arms to the opposing vertically-extending components by applying rotational force in a first direction to threaded members passing through openings in the arms and the opposing vertically-extending components;
- positioning two prongs of a compressor component on a valve spring head, the compressor component connected to the valve spring tool by slideable engagement with an elongate member, the elongate member threadedly engaged with a base component of the valve spring tool;
- applying rotational force in the first direction to the elongate member to compress the valve spring;
- and
- applying rotational force in a second direction to the elongate member to remove the valve spring.
The method of claim 18 wherein the valve spring tool is positioned on the cylinder head while the cylinder head remains in the vehicle.
