The following 42-second video will demonstrate
this technique.
1 Get a stiff metal rod that
will fit inside the spring. A very long shafted screwdriver will also work.
Preferably the rod should be as long as the spring, however a slightly
shorter rod will suffice. A 3/16-inch diameter rod is ideal. The rod should
not have a sharp tip, to prevent scratching, damaging or puncturing the
inside of the hose or your hands.
2 Place the rod securely
in a vise and drop four 1/4-20 common hex nuts on the rod.
3 Use needle nose pliers
to bend the tip of the springs last coil inward so it does not drag against
the inside of the hose.
4 Spray the inside one
end of the hose with a lubricant like SillyCone. Don't get this lubricant
on the outside of the hose. Do not inhale the SillyCone spray. The spring
can also be lubricated with SillyCone.
5 Slip the hose over the
rod and gently compress the spring so the coils are touching. Firmly grip
the hose, close to the vise end of the hose. Do not grab the hose above
the tip of the rod or you may puncture the hose and your hand. Wear heavy
leather gloves for grip and to prevent puncturing your hand.
6 Continue pushing the
hose over the compressed spring. As the compressed coils are inserted inside
the hose, they will naturally spring back and un-compress to a degree inside
the hose. However the inserted spring will be shorter in overall length
than a free spring, once it is completely installed.
7 Repeat step 6 until
the spring is completely inserted into the hose.
8 Remove the hose-spring
assembly from the rod.
9 When finished 1-2 spring
coils may still be visible protruding from the tip of the hose as some
originals overflow hoses exhibit. If your original overflow hoses had the
spring completely inserted with no coils visible, repeat step 6 until 1-2
hex nuts are pushed into and stuck in the end of the hose. Then use a pick
to pull the nuts out of the hose.
CAUTION:
Wear eye protection to prevent eye damage. Do not operate the vise, rod,
spring, hose, pliers or SillyCone after using alcohol or drugs.
