Steve, any petroleum based lubricant will destroy the rubber cushion. The horn should not require ant lubricant. After you replace the horn wire, you will probably never remove the ring until you decide to restore the car. That maybe never. If you do have to remove it again, you can still use the silicone spray for any need lubricant.

Thoughts on lubricating the three fingers of the back of the horn ring before reinstalling appreciated, including recommendations for lubricant if appropriate.

Steve, The horn wire should have about 1 ohm resistance to prevent shocks when you blow the horn and are trying to be casual with your left arm holding the roof on. The silicone probably lubricated the parts so that they could move. The horn ring is pot metal and can be bent back with some heat, but I would not advise you to do this. It is very tricky. If you ever decide to re-chrome the ring, it can be straightened at that time.

Mac's has the horn wire you need, part no.32-10985-2. This fastens to the horn ring with an eye connector and goes down through the column, with bullet connector on the other end. As i recall it did have a lock washer. The excess length should be pulled [not tightly] out the bottom.

Yeah cliftford - as I thought on the pot metal. It's the original so I'll keep it and enjoy it as is. The bend in the bottom of the ring is not too significant and is not noticeable to most anybody but the owner (me) anyway. On the wire - I confirmed my earlier repair and the heat shrink tubing had bound up in the bottom of the steering column. Should any the of exposed wire be left in a curled bend under the horn ring or was it intended that all of it be fed back into the steering column when replacing the horn ring? Also, do you recall if your '48 had a lock washer on the horn wire screw? Thanks - Steve

Steve, I believe the ring is pot metal, at least on a ford it is. Any attempt to straighten it would be highly risky in my opinion. you will want to replace the wire. Most old ford v8 parts dealers should carry them.

Thanks cliftford - after reading your last reply I looked again at the back of the horn ring and see that the medallion for this Merc is not snapped in but is held in place by a ring secured with 3 very small bend tabs that insert through the metal of the horn and are bent outwards - I did not see this before in my initial macro look. A spot of silicone on each of those should do the trick and not come in contact with the back of the medallion. cliftford/Tom/all - can these horn rings be safely bent/reshaped or are they pot metal brittle? Clearly back in the 40's, 50's or 60's someone 'stood' on the bottom of the horn ring and bent it slightly toward the floor - was wondering if this can safely be bent back up or whether work hardening likely has made this a high risk venture. Appreciate any thoughts on the earlier wire questions as well. Steve

Hi Steve, Glad to hear you got the ring off. The suggestions I made were based on my car, a 48 Ford,on which the ring is obvisly different than a merc. On mine, the medallian is held in place by a ring with 3 screws. I was thinking of removing the ring and putting a little silicon under it. Also mine does not have the rubber ring, the spring tension holds it in place. So I guess we were comparing apples and oranges. Good luck and best wishes for the new year.
