replacing the antenna mast

I bought a new antenna unit a few weeks ago and installed it. when I
did, I discovered that the plastic to push up the mast was broken so I
ordered a new one. Now, to get it in? do I need to take apart the
unit like I did while experimenting with the old one, in order to feed
in the plastic? or can I just feed in the plastic with the antenna
unit installed? is there a play by play description of this task to
make my life easier?

and, does anyone want to buy the motor unit that was in my car, and
functioning, but I didn't know it because the antenna mast was torqued
and stopped retracting? turns out that the motor unit turns off after
awhile, which is a good thing because otherwise the motor would burn
out, but I didn't realise that until I bought a salvaged unit and put
it in. Oh well. Live and learn. I'm no Volvo mechanic. :-O

If the plastic is broken then you need to take the motor apart to get
the broken piece out. Otherwise it's a simple matter of making sure
that the motor thinks it's in the up position (radio on, antenna switch
in proper position), then feeding in the mast as far as it will go.
Have a friend turn the radio off (or work the switch) and the mast will
feed itself in. Don't worry if it doesn't go all the way. Put in the
sleeve and put on the nut. Work the antenna up and down.

 

Hi Kate,
I just replaced the mast on my '88 745 Saturday. Here are some tips:

and

I found that on my wagon, I had to remove the silver metal tube into
which the old bottom mast section section is anchored. This is done
by:
1. Remove the chromed nut at the base of the mast.
2. Remove the vertical, upper, left rear plastic panel by the tailgate
to access the silver tube.
3. The silver metal tube has 3 things connected to it. 1) Radio
antenna wire that leads to the radio. 2) Black plastic pipe into which
the white gear retracts. 3) Clear plastic pipe - maybe for water
drainage. I pulled the silver tube down & out, but maybe you won't
have to, however you do have to disconnect it at its base by removing
the 2 Phillips screws.
4. At this point, I pushed the old mast DOWN through the tube to
remove it.
5. Put the new mast UP into the silver metal tube & the white plastic
gear down into the smaller black plastic pipe.
6. Now follow the advice at the above web sites for retracting the
gear.
7. Replace everything you took apart.

Good luck.
