wiper motor type

Can anyone tell me if the wiper motor in a 66F100 is dynamic brake or coast to park? Thanks, JB

JB, In all my 65 years I have never seen this before, where in the world did you get that info from?

Jowilker: If you go to a place like amequipment.com , a firm that specializes in wipers and mechanisms, each switch is available for either coast to stop or dynamic brake wiper motors. Read the faq on the site and you can learn the difference.

One learns something every day. JB

Thanks JB, just so you will know, I have one of the earliest swapped in delay wiper systems on this site. I did so by using the motor from my 76 donor and a harvested switch set from another Ford truck donor.

I know that you have to swap the arm off the back, keeping the original to get it to park correctly. I am concerned about your site that the bolt holes or parking spot are in the correct location. I might grab one from a pick & pull for five bucks rather than paying a hundred plus for one of theirs, and have to send it back.

Your call,



John

time is money

John: To me, time is money. The time I spend prowling the boneyards, removing, and installing an entire wiper system would exceed the time to merely install a switch by a considerable number of hours: more hours than I care to invest.

Thanks for your interest.

John

With the key on, when you turn the wipers off, the blades should return to their original 'parked' position at the base of the windshield.

1965/79 F100/350: Same 2 speed wiper motor.

1966: There are THREE different wiper switches, one for single speed wipers, two for 2 speed wipers.

One of the 2 speed wiper switches has 4 terminals, the other has 7 terminals and contains the windshield washer switch.

Number D: A friend sent me a pic of the motor/switch/ wiper assembly for a 65 F100, and there are only three wires going from the switch to the wiper motor, indicating that it is coast to park. So, by your research, all the trucks from 65/79 have the same set up and will be coast to park.
As always, thanks for your continued interest and input. JB

I do understand, I would like to ask you to post a final on how much time and money you have in your swap when complete.

thanks

Hoss, Aint but one way, remove the retaining nut on the shaft, it'll all be in your hands in about 5 min.

Wiper switch **** retained to wiper switch shaft by #8 -32 headless set screw.

Back off the screw, remove ****...then you'll see a nut with two slots in it nestled into the bezel. Remove the nut, switch will be free of the dash, unplug wires.

Remove a battery cable for safety before reaching under the dash.

What are you guys using for a switch? I need one for the 2 speed wipers in my '61. LMC and DC both list up to '60 and then start again at '67.

ND: Your first piece of inaccurate information. I tried to find a set screw on that thing for a full five minutes yesterday with a flashlight and magnifier, and there is none. My switch controls the washer motor as well, and when I pulled the **** away from the dash, I could see the slots. I got a mirror and looked and looked, and there is not a button release, as there is on the light switch. So, I used the get a bigger hammer approach, and levered it off. The **** is actually molded to the shaft, which was threaded on the far end with flat milled in it to engage the switch mechanism. I guess those threads hold it there by friction.

By the way, JO, there are 4 wires from the switch to the motor, so it is dynamically parked. I would imagine it will take me about an hour or so to wire the new one and install it.

Thanks to all for your interest and comments. JB

I don't know squat about your two dollar and thirty five cent words but I do know how these wiper motors work. Three wires or four only tells you it's either a single speed or a two speed motor, the two motors work exactly the same. The parking circuit is controlled by a cam on the ring gear in the wipers transmission that opens the circuit and stops the wipers in the same spot every time the switch is turned off.
ND is correct. There is NO factory wiper switch that has a molded on ****, they ALL have either a set screw or a spring clip holding them on. Someone in you trucks past may have messed up your **** and then glued it on OR you should have asked how to remove it before you messed it up.
If you need information about a Slick then this is a great bunch of guys with a vast amount of knowledge about these old trucks, but you will learn more from these gentlemen by showing a little bit of humility and using plain english.
'nuff said, Tom

****

Tom: I agree with you about the forum members: tremendous knowledge base.

I assure you that, on my switch, there is no set screw. I also have a 74 that has the spring clips, and this is not that style either. The **** and the shaft are inseparable. They come out of the switch together, and they reinstall together.

Thanks for the info about the 4 wires: I do have a 2 speed switch.
