Horn Contact Repair Instructions
(New Style Horn Cam)
For Part Number 262000010
Instruction #: 8000010051 REV 01/13
The reason this spring gets damaged is due to 12 volts of
power being passed through it. If you have cooked the spring,
the horn is wired improperly. You must use the black wire on
the column as a trigger wire for a horn relay. You can pre-
test this by grounding the wire that comes to the black wire
on the column. It should sound the horn, not spark and get
hot. If you need a horn relay… we have them.
1. You must remove your steering wheel and/or adaptor.
2. Remove the snap ring by using snap ring pliers. (Figure
1) Spread the snap ring apart and work it up the shaft.
You can now remove the horn cam.
Please note: There
is a spring under these components. The spring is similar
to a valve spring, it will come loose with 65 lbs of force
but only has a ¼” stroke.
3. This is the plunger that we are referring to. You should
see it at the 2 o’clock position. (Figure 2 A) If this item
is good, it would be sticking out 3/8”. It would be able
to move in under pressure until it was flush with the
surrounding plastic. On release it should spring back out
to 3/8” past the plastic.
4. You could use any pliers but the side cutters give the
best grip. You are NOT trying to cut this, just pry with
them and use a pulling motion to remove the plunger.
(Figure 3) This is the spring that could be the problem.
Underneath this plunger should be a once piece spring.
This spring should be one piece and not discolored. If this
is burnt, you may need to use pliers or tweezers to remove
all pieces of the spring.
5. To reinstall, set the spring in first, then set the plunger over
the spring and center this over the hole. Using a hammer
and punch, tap the pin back in place.
(Figure 4) This can
be difficult. If it is being difficult, you can lightly sand or
file the lead edge of the plunger to make it start easier.
Installation of Plunger and Spring is complete
(Figure 5)
6. Install the horn cam & snap ring. Use the snap ring
pliers & spread ring and push onto shaft. Set a piece of
tube with an inside diameter of ¾” over the assembly
to compress the spring. Note the column shaft must be
supported at the bottom of the column to do this. We
stand the column on the floor, and push down. You may
have to use other methods if the column is installed in
a vehicle… maybe a floor jack under the bottom of the
column. Some times a helper is necessary to apply and
hold pressure to the bottom with a pry bar. The amount
of force is approximately 65 lbs. When you get this done
you will hear a snap as the clip goes in.

Installation is complete. (Figure 8)
