Each cam has one number and seven letters
around the shaft opening on one side of the cam and
eight letters on the other side of the cam. When
removing cams, mark the letter of the cam which
corresponds to the shaft identification mark; thus
cam and cam followers are removed in succession.
This is done to each succeeding-barrier.
When reassembling, it is only necessary to
stack the cams back into the shaft in the same order
as taken off, keeping the proper cam letter lined
up with the shaft identification mark.
Before tightening the tie bolts into the front
support, make sure that all the barriers are properly
nested.

now be assembled, placing the stops, if present, in
their proper position with respect
to
the shaft
identification mark.
