Camshaft install tips and tricks

On a complete engine assembly, it is often helpful to install the camshaft BEFORE the crankshaft; in many cases the cam would be the first part to be installed by the assembler after "final cleaning" of the block. (The cam bearings are likely to be installed by the machine shop.)  If this is the case, it is very helpful to--if possible--set the block on the floor bellhousing-side DOWN, so the block is vertical.  The camshaft then can be lowered into the block straight down, and there's minimal effort needed to assure that the cam lobes and cam journals DO NOT nick the bearings.  If the cam MUST be installed horizontally, it is almost mandatory to use a "handle" on the front of the cam, and to take particular care that the cam doesn't bang into, or scrape across the bearings.  Whether vertical or horizontal, if the crankshaft isn't in the way, it's easy to guide the cam through the bearings with one hand while supporting the front end of the cam with the other.
