Before installing your new mast, compare the old mast with the new one.
They need to be identical in every way. If they are different, you may have
an after market power unit. Also it is very important that you
cut the white cable on the new mast at any time.
Remove the nut on the outer end of the power unit where the mast comes
out of the fender.
2. As someone turns the radio on and as the mast begins
or tries to come up,... grab hold of it and pull out the old mast...taking note which direction the teeth on the plastic
center cable are facing so you know which
way the new mast cable is to face when you put it in. ( With your
Sequoia the toothed cable faces
FORWARD )..... Make sure that the short
outer grounding/retaining sleeve ( as what is on the outer NEW antenna
mast ) has come out with the old mast, this is very important, as this is what holds the antenna
mast in when the nut is fastened..... If the old mast and grounding/retaining
ring are out then proceed with step 4. If not proceed with step 3.
3. If at this time you canít pull the mast out and it
seems to be stuck, more than likely the grounding/retaining sleeve is
corroded to the top of the antenna tube. What one needs to do at this point
is Pull the mast extremely hard and it will come out. If at this
time the old mast comes out proceed with step 4.
4. Compare the old mast with the new one, the length of
the white teethed cable MUST be the same length of the one you took out of
your power unit (DO
NOT CUT THE NEW MAST CABLE).... If the cable is not the same length,
then you probably have a broken piece left in your power unit.... If the cable
is shorter proceed with step 5.... If the over all length of the stainless
portion of the mast and diameter are the same along with the white cable
length continue with step 6.
5. There are occasions where the antenna
mast cable breaks off
in the power unit and this will not allow the replacement mast to be pulled in
all the way. SO IT MUST BE REMOVED. In this event you will have to remove the power antenna
assembly from your Sequoia. This
is done by turning the wheel extremely sharp to the right. ( Or
Remove the Right front tire ). Now
remove the screws that hold the plastic splash pan from under
the fender, from the lower rear of
the fender up to about the middle of the fender and then push the splash pan
out of the way. Next at the base of your power antenna unit there is a
bolt remove it, now the power unit will drop enough for you to work on
it. Next pull up the plastic cover from
around the power unit and now you will see the cover on the lower motor section of
your power antenna, looks like its covering a dounut, remove it and as you do you will see
what looks like a donut
looking plastic drum, pull it out from the antenna and then manually remove the broken
portion of the cable from inside that drum. Once the cable is out, clean the
old grease out from the drum assembly
before you reassemble the drum
use a light grease or white grease in that drum
assembly.. Put the cover back
on, once this is done, now reassemble the
power unit back up into the fender of your
Sequoia and proceed with step 6.
6. Insert the new mast cable into the top of the power
antenna tube on top of the fender with the teeth facing toward the
FRONT of your Sequoia,.. then have someone turn the radio off,.. as the power unit begins to
pull the new mast in, guide the new antenna mast cable and mast into the power unit, as it pulls
the mast down into the power unit, it may on the first try not pull the mast
all the way down, donít worry, install the outer nut and then turn the radio on
and off a few times as this will center the new antenna mast in its proper
place, then, "Voila! The mast is installed."
