Abstract

The invention relates to a camshaft mounting for a one-piece camshaft supported in a cylinder head having three undivided bearing blocks. The camshaft 5 has three bearing portions of small diameter. One end bearing block (4) has a bore of the same diameter as the bearing portion 8. The middle bearing block 3 has a bore 12 of the same diameter as the bearing portion 7 and a cut-out 13 shaped to allow the cams 9 to pass through one by one if the camshaft 5 is correctly oriented. The last bearing block has a larger bore 16 and is fitted with a bush 15 after insertion of the cams of the camshaft. The camshaft is assembled by sequentially rotating it to align the cams one by one with the cut-out 13 and axial displacement. The bush 15 may be inserted after the camshaft has been slid into position or may be placed over the bearing portion 6 before the camshaft is finally pushed home.
