Abstract
A valve spring compressor has a main body 11 which is fixed to a cylinder head block by means of a bolt 15 which is passed through a bracket 12 at one end of the body. A head 13 is attached to the other end of the body and is adjustable by means of a pin passing through a hole in the body and engaging in one of a series of holes in the head. A clamp 14 is located in the mid region of the body and is fixed rigidly to the cylinder head. A nut 16 is tightened on the clamp to force the head 13 down to compress a valve spring 17.
Description
2324265 THE OVERHEAD VALVE SPRING COMPRESSOR This invention relates to an
overhead valve spring compressor.
Valve stem seals are seated on top of the cylinder head of a combustion engine.The stem of the valve passes through it,when the seals are worn they no longer stop the oil leaking into the combustion chamber.The oil then mixes with the fuel causing smoke emission.This is detremental to the atmosphere and increases oil consumption.
It is generally the practice to remove the head of an engine whenever it necessary to replace worn valve stem seals.The head is removed from the engine block,placed on a workbench and a valve spring compressor is employed,one end is positioned on the valve head the other end has a means to compress the spring, this system is both time consuming and expensive.
According to the present invention, to change the valve stem seals it is no longer necessary to remove the cylinder head from the engine block. There is provided an overhead valve spring compressor, comprising a tool with the means to compress the valve springs from the top of the head.
HERE IS A BRIEF DESCRIPTION OF THE DRAWINGS.
Fig 1 shows the body of the tool with support bracket,which has the ability to slide to any position on the tool.
Fig 2 shows the head of the tool which has the means to adjust to di f f erent positions by means of a series of tapped holes held into the body by a bolt.
Fig 3 shows the main clamp of the tool,when the overhead cam is removed this clamp is positioned on the head where the main bearings of the camshaft sit.
Fig 4 shows the adjusting legs which screw into the support bracket (Fig 1).
Fig 5 illustrates the tool being employed on the valve spring in a sectional view from the side of the engine.
Referring to the drawings, Bolt down the main clamp(14)to the fixings for the camshaft bearing.Place the body(ll)of the tool in position,adjust the head(13)to the required position,adjust the support bracket(12)and the adjusting legs(15)until the tool(ll)is level,tighten down the nut(16)on the main clamp(14)thus compressing the valve spring(17)release the split collets(18)slacken the nut(16)on the main clamp(14)to release pressure on the spring(17)swing the tool(ll)out of the way,remove the spring(17)the seal (20)can now be changed.
Claims (1)
