Repair camshaft

If the radial runout of the camshaft is not to tolerance (variation in concentricity of camshaft) this is rectified with a crankshaft straightening press:



- The camshaft must be mounted only at the first and seventh bearing journals and

- pressure must be applied only at the forth bearing journal.

If scores are present in the bearing journals of the camshaft, the bearing journals are re-ground with a crankshaft grinding machine in accordance with the defined repair size:



- All the bearing journals must be matched to the same repair size.

- It is important to maintain the specified peak-to-valley height.
