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.
Claims17
A device for removing a valve spring, comprising:
- a base component adapted to engage with opposing vertically-extending components on a cylinder head;
- 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;
- and
- a fastening component threadedly engaged with the elongate member such that, when rotational force is applied in a clockwork direction to the fastening component, the compressor component is forced in a downward direction.
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.
