Assembly
1. Basic assembly is the reversal of the above steps.
2. It is important to make sure all parts are clean and properly lubricated where needed.
3. A thin coating of light grease should be applied to any sliding or rotating surfaces
before assembly.
*Note: If you should need to remove the spring, the easiest way to rewind the old spring
is to make a mandrill from a piece of round stock about 1/2” in diameter. Drill and tap a
hole in the rod for a screw similar to the end of the shaft (107) on the machine where
the spring is to be installed. Put the mandrill in the lathe chuck and slip the spring over
the screw head. Drill and tap a hole in the side of a lathe tool and install a screw similar
in size to the screw in the spring housing. Put the tool in the tool post in a manner that
the screw head can be hooked to the end of the spring. Slowly turn the lathe spindle by
hand as you also feed the tool post inward to keep pace with the spring as it winds up
and gets smaller and smaller in diameter. When the spring is wound to a size smaller than
the spring housing, wrap wire around the housing to hold it wound while you remove it
from the mandrill and install it into the housing.
