Power seat parts

[flathead48]

Restoring 56 Mercury and looking for info on power seat motor drives, I am missing parts that drive the forward & reverse screw. Thanks

Sounds like you are just missing the motor. Looks like Mac's has them for Thunderbirds. I would think they might be interchangeable.

Maybe these Ill's will help -

i think I have everything for my power seats on my 55, they have never been hooked up since the restoration was done. I guess they are 6 volt motors, what would it take to make them work on 12 volts?

A solid state 12 to 6 volt reducer would probably be best. The wire wound ceramic reducers won't heat up enough to reduce the voltage by much in the short time you'd be using the seat motor. That said they'd prolly work just fine on 12v. The seat will just move 2X as fast as normal. My Merc has 6 volt factory power windows and they work well on 12V. Just keep appendages out of the way when closing them. They are the same motor as your seat motor.

Do you have a good wiring diagram for hooking them up? They only need to be connected correctly, and will work just fine on 12v unless you abuse them.

Thanks for the replies, no I don't have a wiring diagram. If someone has it I would like to have a copy. Al

Thanks guys for the responses but what I need is the gear that connects the motor shaft to the screw arm that hooks to the seat goes inside 60418.

60481?

[Merc Cruzer]

This might be the same or similar gear he is looking for. The transmissions appear to be similar in design. These pictures are of the motor and screwjacks used in m y 53' Merc.

60481 Is The Drive Assy. The actual gear is (was) available separately.

[flathead48]

Thanks again guys, the gear is what I need, any ideas where one could buy one ?

[Merc Cruzer]

If you know the part number you can try Green Sales.

[KULTULZ]

The PN is BN 7060471-A.

I did not see any on a search but the PN may have been superseded.

Make sure the diagram(s) matches your power seat type.

[Dobie Gillis]

These goobers show one:

$50, OUCH!

[Merc Cruzer]

You might be able to buy a whole unit for parts, with a burnt out motor, for less than $50. Just a thought.

Is that the same gear part number for the 1953 Power seat? Any way to check other years and applications for that part number?

You know for 50 bucks, that might be able to be made on a 3D printer, if by chance you have the original gear. Just a thought.

Same price but made out of Brass:

If you have the original gear and know someone in tool and die, it might be another option.

[flathead48]

Used unit would be great, thanks for all the input.

The gear shown is a different PN -

The problem is with text this old is you would need a period OSI (Obsolete-Supersede-Interchange) Catalog to see where the original PN may have been updated. Different publication dates of cataloging may show an updated PN with no explanation of an update.
