SplitCam

 

In engine designs where the camshaft is inserted through the camshaft bearings, the diameter of the bearings become a limitation on the design of the cam lobes

 

AGAP has developed a patent pending principle which makes it possible to use significantly larger cam lobes than what otherwise would be possible. The technique can be used on new designs but is maybe most suitable to improve an existing design where it is not practical to increase the diameter of the camshaft bearings or in certain racing classes where regulations 

may stop such modifications. 

 

The principle is based on that the camshaft bearing journals are detachable and assembled with the camshaft once the cam is inserted in the engine. Below a split cam is shown together with a standard camshaft.

 

 

 

The camshaft in this case can be inserted in the engine by being angled down in between the camshaft bearings, another alternative would be to insert the camshaft through the cam bearings radially displaced.

 

 

 

By closer inspection it is evident how much the cam lobe extends above the camshaft journal, ¼ inch to be specific. If this technique had not been used the camshaft bearings would have had to be ½ inch larger in diameter, which had not been practically possible in this application.

 

 

 

 

 

If you are interested in having a camshaft developed for your application or you whish to use the technique yourself, please contact us.

 

Among the products you can find a camshaft developed for Ford Model A, which also happens to be the camshaft you have been looking at in these pictures.
