FIC 3500 electric tongue jack

[Hotvawt]

I have an FIC 3500 electric tongue jack on my 2016 Jayco octane toy hauler. When I take the little rubber grommet off the top of the jack housing to use it in the manual mode is there supposed to be a nut in there to connect to? Mine does not seem to have that. And I don’t seem to have the manual operation handle to operate it. I think I can order a jack handle. But I don’t know what it hooks to since there is no nut in there. Does someone have a picture of the inside of one of theirs?

My electric tongue jack is a different brand. I'm not sure but I think it's Lippert. The manual override on it uses a 3/4 or 19mm socket. I've read that some tongue jack overrides have a square hole in the top such that you would use a ratchet 3/8's drive extension... though maybe it was a 1/2 inch drive. I don't remember which.

I did see one of those jacks a while ago, and it took a socket on an extension, with a ratchet. I don't know if it was the same year or model of yours. Try some socket sizes like 7/16" or 10mm. If that's not it, they may have changed the motors to a different manual crank handle.

I think being a 2016 Mikec557 is correct with the 3/8" or 1/2" drive. Take a flashlight and look at the top of the shaft. The opening for whatever drive you have should be visible.

A lot of the tongue jacks come with a wrench for manual operation. My Bulldog jack has a slotted wrench.

We have a FIC 3500 electric tongue jack on our 2019 Jayco 264BHW. There is a nut located under the rubber grommet that the jack handle attaches to when using it in the manual mode. Although the trailer came with the manual crank handle, I bought a cheap ratchet, 6" extension and a socket from Harbor Freight I keep in the trailer to use instead of the long (and IMHO unwieldy) jack handle. Sorry I don't remember the size of the nut, nor do I have any pictures of the internal working of the electric jack.

Did you buy the trailer new? Would the previous owner have any thoughts on the matter? I have no idea why the "manual crank nut" is not on your tongue jack drive shaft. But somehow it may have fallen off the drive shaft and is probably down inside the plastic housing. There are a few screws located on the back of the plastic housing that hold it together you can remove to open the housing to retrieve and reattach the loose nut.

My Bulldog jack does not have a hex nut, it has a round nut with a roll pin thru it. Special crank wrench.

The backup crank for the FIC 3500 electric tongue jack that was supplied with my then new Jayflight SLX didn’t even fit through the hole in the top, it did fit the stabilizer jacks, so I had 2 cranks for the stabilizer and none for the tongue jack.

I discovered this when the 4 y/o trailer started showing age issues. One if this being the electric jack would only raise the jack not lower it. I tried different sockets and found the 7/16 would fit, however the socket came off the extension while inside the jack head so I ended up taking the jack head apart. I did get the jack working manually with the 7/6 socket and ratchet , however it’s time consuming.

By trial and error I discovered the switch wouldnt close the circuit to put the jack down, but if I reversed the contacts I could use the UP switch to put it down. Of course I have to leave the jack head disassembled, but will replace the switch when I return from this trip and button things up again.


I attack 3 pics, the switch, the 7/16 shaft that you need to turn, and a bag I got from Amazon the cover the jack head
